THE SUSSEX CATTLE<br />
BREEDERS SOCIETY<br />
OF SOUTH AFRICA<br />
INSPECTION STANDARDS<br />
(TO BE READ IN CONJUNCTION<br />
WITH THE<br />
STANDARD OF EXCELLENCE)<br />
The <strong>Sussex</strong> is a medium size beef<br />
animal, with good fertility and milk<br />
characteristics, which is well adapted to<br />
a variety of Southern Africa climatic<br />
conditions. Its role in the industry is<br />
that of a specialized male line, whose<br />
major function is in producing crossbred<br />
commercial females, or steers<br />
which can be economically produced<br />
under extensive conditions, or as a<br />
third cross in a three-way crossing<br />
system. The following <strong>Breed</strong><br />
<strong>Standards</strong> should therefore be applied<br />
with these functions in mind:<br />
- FERTILITY<br />
- GOOD MILK SUPPY<br />
- ADAPTABILITY, ESPECIALLY<br />
UNDER EXTENSIVE HOT AND<br />
COLD CONDITIONS<br />
- GOOD POST-WEANING<br />
GROWTH, LEADING TO MEDIUM<br />
MATURE SIZE, WITHOUT<br />
SACRIFICING EASY CALVING.<br />
- GOOD FEED CONVERSION<br />
5<br />
Vroulik:<br />
Goed ontwikkelde vulva. Uier goed<br />
ontwikkel wat vier goed geplaasde<br />
spene vertoon.<br />

INSPEKSIESTANDAARDE<br />
(OM IN SAMEHANG MET DIE<br />
STANDAARD VAN<br />
VOORTREFLIKHEID GELEES TE<br />
WORD)<br />
Die <strong>Sussex</strong> is ‘n medium grootte<br />
vleisbees met goeie vrugbaarheid en<br />
melkeienskappe, wat goed aangepas is<br />
by ‘n verskeidenheid van Suider<br />
Afrikaanse klimaatstoestande. Die rol<br />
wat hy in die bedryf vervul is die van<br />
gespesialiseerde manlike lyn en sy<br />
hooffunksie is om kommersiële<br />
kruisgeteelde vroulike diere of slagosse<br />
wat onder ekstensiewe toestande<br />
ekonomies aangehou kan word, te teel<br />
of as ‘n derde kruis in ‘n drieledige<br />
kruisteelstelsel gebruik te word.<br />
Rasstandaarde moet dus teen die<br />
agtergrond van ondergenoemde<br />
aspekte toegepas word.<br />
- VRUGBAARHEID<br />
- GOEIE MELKVOORSIENING<br />
- AANPASBAARHEID VERAL<br />
ONDER EKSTENSIEWE WARM<br />

PRINCIPLES OF STUD BREEDING<br />
Professor A.O. de Lange, Faculty of Agriculture, U.O.F.S.<br />
About five years ago, Mendel’s laws of<br />
heredity were re-discovered. How has<br />
this influenced breeding practice? In<br />
one sense detrimentally and other<br />
instance beneficially. Detrimentally in<br />
the sense that it promoted an oversimplified<br />
view of breeding<br />
improvement. It was an inevitable<br />
consequence of the kind of<br />
characteristics which were exceedingly<br />
well suitable for genetic studies –<br />
discreet, qualitative differences<br />
reflecting a firm Mendelian pattern of<br />
hereditary. The result was a school of<br />
thought directed at “good” and “bad”<br />
genes and a breeding of homozygosis<br />
of the “good” genes. This approach<br />
had two particularly detrimental side<br />
effects:<br />
1. The belief that in-breeding is an aid<br />
in selection because is promoted<br />
homozygosis, and<br />
2. The exaggerated value attached to<br />
uniformity.<br />
From the 1940’s more and more<br />
empirical research was carried out in<br />
two, one can say almost “new” fields of<br />
genetics, namely biochemical genetics<br />
and the genetics of populations. The<br />
circumlative results of a wide variety of<br />
experiments have gradually, over the<br />
years, led to a new perception of the<br />
complex nature of genetic variation<br />
which actually only clearly took shape<br />
during the past one and a half decades<br />
– in fact, this is still taking place. There<br />
are four particular aspects of cardinal<br />
importance for a realistic view of<br />
breeding improvement: the extent of<br />
variation existing in a population, the<br />
role of sexual reproduction, the unity of<br />
the genotype and in-breeding decline.<br />
Firstly, let us consider briefly the<br />
genetic differences in a natural<br />
population – which is indeed the raw<br />
materials with which an animal breeder<br />
works – and see how we can<br />
manipulate them to bring out breeding<br />
improvement.<br />
Types of differences<br />
All differences among individuals can<br />
be classified into two main groups:<br />
discreet differences and continuous<br />
differences. The former of the two<br />
includes traits such as horns, colour,<br />
blood group types, etc. Selection for or<br />
against such traits is relatively easy and<br />
the breeding ideal is mainly uniformity.<br />
Selection for a recessive trait is<br />
hundred per cent effective and all<br />
individuals that reflect the trait<br />
externally will henceforth breed pure for<br />
that particular trait, as will their<br />
progeny. Selection for a dominant trait<br />
is not quite as effective – as the<br />
recessive genes are being excluded,<br />
they are increasingly hidden in the<br />
heterzygotes. When a recessive gene<br />
is very rare in a population it wil by<br />
nature seldom occur in the<br />
homozygous condition. To incur<br />
trouble and costs especially to test<br />
male animals before use to establish<br />
whether they possibly carry such<br />
genes, is not worth the while. Say for<br />
example that one of 20,000 cattle<br />
reflects a certain detrimental recessive<br />
trait, then one out of every seventy<br />
bulls will be a carrier of the recessive<br />
gene in the heterozygous condition.
The chances that he may serve a<br />
heterozygous cow are 1/70x1/70 =<br />
1/5000. The possibility that she will<br />
have a recessive homozygous calf is _,<br />
in other words, it takes us back to the<br />
frequency of the trait in the population,<br />
namely 1/4x1/5000 = 1/2000. To go<br />
and carry out the necessary test<br />
matings to identify this bull as a<br />
heterozygote only to prevent those<br />
1/2000 undesirable calves, is simply<br />
not worth the time and the cost.<br />
Production Traits<br />
In contrast with discreet differences the<br />
vast majority of economically important<br />
traits reflect continuous variation, for<br />
example milk production, growth rate,<br />
wool production, size, length, width,<br />
etc. The population cannot be divided<br />
in a few clearly defined classes and<br />
variations among individuals are merely<br />
degree variations in contrast with the<br />
absolute differences of the discreet<br />
traits. Characteristic of the type of traits<br />
is the fact that should we measure a<br />
large enough sample of individuals, the<br />
values would be divided campanuately.<br />
In other words, the majority of he<br />
population does not deviate much from<br />
the average – the large the deviation,<br />
the more such rare individuals become<br />
(See Fig 1)<br />
15<br />
Extent of variation<br />
By far the most surprising result of the<br />
experiments referred to above is the<br />
astounding extent of genetic variation<br />
occurring in the populations. According<br />
to the classic genetics one would<br />
expect that the loci of a specific species<br />
must be predominantly homozygous<br />
owing to the prolonged effect of the<br />
selection. Two sources of evidence<br />
reflect however, that the genetic pools<br />
which we manipulate in animal<br />
breeding, show amazing variation.<br />
Studies of electrophic variants of the<br />
same protein indicate that<br />
approximately a quarter and a half the<br />
gene pairs of sexually reproductive<br />
species, alternative genes are found in<br />
the same locus (Lawontin, 1973). This<br />
means that there must be literally<br />
thousands of gene pairs in any breed<br />
where alternative gene combinations<br />
are possible. This in turn, ensures that<br />
each individual must have a unique<br />
genotype.<br />
The second type of experiments<br />
shedding light on the question of how<br />
much variation exists in a population, is<br />
long term selection for a specific trait<br />
until later it not longer reacts. In a<br />
review of such experiments Krass<br />
(1975) found that the total response to<br />
selection vary much from trait to trait<br />
and from organism to organism. The<br />
average variation was about a threefold<br />
increase or decrease of the population<br />
average. This is a very large variation<br />
and indicates a particular pliability of<br />
the gene pool. Moreover, two<br />
unexpected phenomena came to light<br />
in these experiments. The first is that<br />
the variation in regard to the particular<br />
trait for which is selected, frequently<br />
tends to increase rather than decrease;
and the second is that even after the<br />
population stood still at a selection limit<br />
for a considerable period of time, it<br />
reacts immediately on reversed<br />
selection in the vast majority of cases,<br />
In other words, the genetic variation is<br />
also not exhausted noteably by<br />
selection.<br />
Variety is Normal<br />
The first principle that we should<br />
understand, therefore, is that the<br />
animal breeder is busy manipulating a<br />
highly variable genetic pool. The<br />
second major principle to remember is<br />
that the primary function of sexual<br />
reproduction is in fact to maintain this<br />
generic variation. No two individuals in<br />
a sexually reproductive population<br />
appear or are alike – no two people,<br />
sheep, horses or whatever. Each fly on<br />
the windowpane has it’s own face like<br />
every human being has his or her own<br />
face. They only appear alike to us, just<br />
like the animals of a stud breeder will<br />
appear like to the inexperienced city<br />
dweller.<br />
Avoid In-breeding<br />
At last we can accept, after half a<br />
century’s controlled matings of<br />
affinities, that species which normally<br />
reproduce sexually , retrogress with inbreeding<br />
and that even strong selection<br />
pressure has barely any influences in<br />
counteracting this retrogression<br />
(Pircher, 1969). Even with poultry,<br />
where it is possible for in-breeding to<br />
take place much faster than with bigger<br />
farm animals, Stephenson and his coworkers<br />
came to the conclusion that<br />
“strong in-breeding can decrease<br />
16<br />
performance much more effectively that<br />
selection can increase it. Therefore it<br />
hardly seems economical to produce<br />
inbred lines for commercial use”<br />
(Stephenson et al. 1953). The<br />
success stories which in practice are<br />
frequently attributed to in-breeding on<br />
closer investigation, usually appear to<br />
be more likely due to selection.<br />
Against this background, namely the<br />
extent of variation that is present,<br />
sexual reproduction, the unity of the<br />
genotype and in-breeding retrogression<br />
a few remarks on a number of aspects<br />
of breeding in practice, are relevant.<br />
Firstly avoid in-breeding. Why follow a<br />
mating system which even in the<br />
vegetable kingdom, nature goes out of<br />
its way to avoid? Don’t take the<br />
botanist as an example. His situation is<br />
totally different because he can, for<br />
example, self-fertilize maize, he can<br />
reach a degree of in-breeding which<br />
would take 40 years of parent-onprogeny<br />
or full blood brother on full<br />
blood sister with farm animals. The<br />
botanist normally does at least 5<br />
generations of self-fertilization before<br />
he starts crossing. Also remember that<br />
the approximately 60 inbred maize lines<br />
used for the reproduction of hybrid<br />
maize in the USA towards 1950, were<br />
selected from about 100 000 original inbred<br />
lines.<br />
Selection the Key to Success<br />
Selection remains the most powerful<br />
method to change the genetic<br />
composition of the population. Often,<br />
however, selection takes place exactly<br />
with the view to stabilizing the<br />
population average at an intermediate<br />
optimum (for example fibre diameter in<br />
the case of Merino’s). This type of
selection has three results: naturally it<br />
decreases the variation of the present<br />
population, but it has no notable effect<br />
on the variation of the next generation<br />
and it prevents a change of the<br />
average.<br />
More often, however, selection is aimed<br />
at a higher or lower value, for example<br />
for bigger or smaller animals. This<br />
results in displacement of the<br />
population averages, but again the<br />
variation is seldom notably influenced.<br />
The differences between the best and<br />
the poorest remain about the same, but<br />
both groups continue to improve. It is<br />
simply not possible to get all the<br />
animals of a large stude to be equally<br />
as good. Inherently they differ from<br />
each other and for this very reason<br />
sexually reproductive populations ar so<br />
pliable and therefore susceptible to<br />
selection. For this reason the<br />
Simmentaler in Germany could be<br />
selected as a dual purposed breed,<br />
while the same breed is primarily a beef<br />
breed in Australia.<br />
There are no short cut magic formulas<br />
to change the genetic composition of a<br />
breed overnight (except, of course,<br />
through crossbreeding with another<br />
breed). It is a question of continuous<br />
selection pressure with a firm objective<br />
in mind. One or two percent progress<br />
in a year is the best one can hope for in<br />
the majority of cases. This is why it is<br />
so important to limit mistakes to the<br />
minimum. Firstly, and perhaps most<br />
important, with regard to objectives, but<br />
of course also as far as selection itself<br />
is concerned.<br />
17<br />
Objectives<br />
One of the most difficult aspects in<br />
animal breeding is to formulate clearly<br />
outlined breeding objectives. Consider<br />
the changing needs of the market; the<br />
diversity of conditions in which the<br />
same breed must produce the lack of<br />
knowledge on exactly what the breed<br />
originally looked like; and where one’s<br />
physiological limits are, then one can<br />
understand why breeding objectives<br />
are vaguely formulated in terms of<br />
breed standards. <strong>Breed</strong> standards, in<br />
the case of older breeds, are in many<br />
respects a description of the breeding<br />
progress already achieved. One<br />
should expect in these cases that breed<br />
societies should rather entertain the<br />
view that the vast majority of their<br />
animals conform to the breed standards<br />
at any rate, and that the differences<br />
that do occur are very natural and will<br />
always be there if the population<br />
reproduces sexually (in contract with,<br />
for example, cloning). Instead of being<br />
possessed by ideas of breed<br />
standards, such a bred society should<br />
incessantly propagate the strong<br />
aspects of its own breed, while the<br />
breeder asks himself: in respect of<br />
which traits should my breed be<br />
improved further, and selection should<br />
then be aimed primarily at those traits.<br />
The major function of the stud breeder<br />
is to provide bulls to the conventional<br />
producer. The bulls that he provides<br />
should, however, possess certain<br />
characteristics and it is firstly important<br />
for the breeder to formulate these<br />
characteristics clearly for himself and<br />
then strive for them consistently. When<br />
establishing objectives, three factors<br />
should be borne in mind: the objectives
must be meaningful, they must not<br />
change too frequently and the number<br />
of characteristics taken into<br />
consideration must be minimized. In<br />
the short term, the stud breeder with<br />
salesmanship can convince the<br />
commercial customer that what he has<br />
to offer, is exactly the right thing. In the<br />
long term only those breeders will<br />
remain in the industry who offer bulls<br />
that are lucrative to form with to the<br />
commercial producer. Therefore it is so<br />
vitally important for the stud breeder to<br />
have clarity about what he is trying to<br />
breed. Secondly one must realize that<br />
there is no instant formula in breeding<br />
improvement – it is based on sustained<br />
selection in regard to the set objectives.<br />
If these objectives change too often<br />
(which happened frequently with some<br />
of our livestock breeds in the past), it<br />
cannot be expected that much breeding<br />
progress will be made.<br />
Thirdly, it is a well-known fact that each<br />
animal possesses good as well as<br />
undesirable traits. The more<br />
characteristics are therefore bone in<br />
mind during selection, the weaker the<br />
selection pressure will be in regard to<br />
any one seen separately.<br />
Accurate Selection<br />
With the objectives clearly defined, the<br />
following important aspect is the<br />
techniques used to measure the traits<br />
on which have been decided. The<br />
more accurately the animals are being<br />
evaluated, the larger the selection<br />
progress will be. The golden principle<br />
is to measure all traits that can be<br />
measured objectively instead of<br />
estimating subjectively, for instance<br />
body mass, height, length, width and<br />
18<br />
depth, etc. The second principle is, as<br />
far as possible, to select directly for the<br />
traits which we want to improve. For<br />
example, if one wants to improve<br />
fertility, one should select for it<br />
specifically instead of, for example, only<br />
considering the performance of the<br />
mother of the bull.<br />
Performance Testing<br />
Performance testing as such is no new<br />
concept. The performance of a plant or<br />
animal was, through all ages, the<br />
foundation on which selection was<br />
based. Herein, however, we use the<br />
term to refer to the objective measuring<br />
certain traits of breed, for this is what<br />
performance testing actually is – a<br />
measuring technique. It is not a<br />
breeding system and the question<br />
which is often asked, namely whether<br />
performance testing can replace the<br />
breeder, is therefore out of context.<br />
The breeder’s function is decision<br />
taking and this function cannot be<br />
replaced by a measuring technique or<br />
any data processing system. Any<br />
decision however, based on information<br />
and this is where measuring data<br />
processing enter the picture – they<br />
provide information to form a basis for<br />
decisions.<br />
Selection Theory<br />
Selection is the most powerful means<br />
at our disposal to recreate plants or<br />
animals according to our needs, and<br />
breeding improvement within a breed is<br />
based mainly on selection. The<br />
difference between the outstanding<br />
animal and the mediocre breeder is<br />
mainly attributable to effective
selection, although management skill is<br />
a prerequisite and a good farming<br />
contributory factor. With efficient<br />
selection we mean the ability accurately<br />
to judge the value of an animal as well<br />
as good judgement on the relative<br />
importance of the various traits for<br />
which are selected. In practice,<br />
selection progress will be determined<br />
by the following factors (over which we<br />
have no control):<br />
• The number of traits for which are<br />
selected, limit this to a minimum.<br />
One wonders often, for example,<br />
whether it is worthwhile to divide a<br />
trait such as conformation into head<br />
and neck, forequarters, middle piece<br />
and hindquarters. In practice, the<br />
points awarded are so often<br />
determined by the size of the animal<br />
that it would perhaps be better only to<br />
point a “general appearance”. Size<br />
and body size can rather be<br />
described in terms of objective<br />
measuring.<br />
• The proportion selected. This<br />
determines the superiority of the<br />
selected animals and is therefore<br />
extremely important. In practice it<br />
will depend on reproduction rate and<br />
replacement needs. The latter, in<br />
turn is largely determined by the<br />
generation interval, which we will<br />
discuss later.<br />
• The accurate elevation of animals.<br />
This is one of the most important<br />
aspects of selection. The accuracy of<br />
selection, firstly, directly determines<br />
the response obtained by selection.<br />
Secondly , the figures so obtained are<br />
priceless value to determine breeding<br />
policy. Many futile arguments take<br />
place about breeding policy simply<br />
because the data on which<br />
arguments can be based, are not<br />
19<br />
available. Measuring the<br />
bookkeeping is imperative if one<br />
strives for maximum breeding<br />
progress. Without it, it is not even<br />
possible to determine the extent and<br />
nature of the progress that is being<br />
made.<br />
Population Size<br />
After the objective has been set and<br />
decisions on accurate measuring<br />
techniques have been taken, the<br />
selection progress will further depend<br />
on the effective size of the breeding<br />
unit. Population size influences the<br />
selection progress in a dual way: the<br />
possibility of achieving favourable gene<br />
combinations are better in a large<br />
population, and risk of in-breeding<br />
smaller. The gene pool of any member<br />
of individuals found in such a species<br />
represents but a fraction of the<br />
potentially possible gene combinations.<br />
The larger the population is, therefore<br />
the better are the chances of getting<br />
individuals with favourable gene<br />
combinations. It has, in fact, been<br />
found in selection experiments with<br />
vinegar flies, that a low selection<br />
pressure in a large population brings<br />
about more progress than a high<br />
selection pressure in a small<br />
population. It is also noteworthy that<br />
the top studs in any ramification of<br />
animal breeding are always of an<br />
above average size. It is sometimes<br />
said that apart from the<br />
knowledgeableness a stud breeder also<br />
needs a bit of “luck” to get to the top. In<br />
my view this luck element is strongly<br />
connected with stud size. Provided<br />
other factors are even, the large stud<br />
will be “luckier” than the small one.
Economics of <strong>Breed</strong>ing<br />
Improvement<br />
In conclusion, a few remarks on the<br />
economics of breeding improvement.<br />
Strictly speaking breeding improvement<br />
should not be expensive and in view of<br />
the cumulative effect is should yield an<br />
excellent long-term profit. In practice,<br />
however, this Is frequently not the case<br />
because of a general tendency to pay<br />
prices for breeding animals that are<br />
hopelessly out of proportion to the<br />
possible improvement that they can<br />
achieve. This attitude is again due to<br />
the disregard of the role of sexual<br />
reproduction in nature. An outstanding<br />
ram or bull on average always breeds<br />
poorer than what he himself is, and an<br />
extremely poor individual, on average,<br />
better than itself. Sexual reproduction<br />
sees to this, because it tends to<br />
maintain the status quo of the<br />
population. The breeder can,<br />
conversely, force the population into a<br />
direction through selection, but this<br />
usually takes place at a relatively slow<br />
pace.<br />

DIE NASIONALE<br />
VLEISBEESPRESTASIETOETSSKEMA<br />
Die Nasionale Vleisbeesprestasie- en<br />
nageslagtoetsskema is op 4 Desember<br />
1959 in werking gestel. Sedertdien het<br />
die skema tot ‘n goed georganiseerde<br />
program ontwikkel wat ‘n groter invloed<br />
op die bedryf as geheel uitoefen as wat<br />
algemeen besef word.<br />
‘n Adviesraad komitee, bestaande uit<br />
verteenwoordigers van die verskillende<br />
sektore van die bedryf, hou toesig oor<br />
en dien as adviseurs vir die skema met<br />
sy verskilende fases. Die leiding wat<br />
van hierdie advisering ontvang word, is<br />
een van die redes vir die kursus van die<br />
skema.<br />
Doel van die Skema<br />
Die doel van die skema kan in die<br />
volgende paar punte saamgevat word:<br />
1. Die belangrikste doel van die<br />
skema is om die gemiddelde<br />
prestasies van die nasionale kudde<br />
vir die ekonomiese belangrike<br />
eienskappe te verhoog.<br />
2. Om met behulp van objektief<br />
bepaalde inligting die genetiese<br />
verskille tussen diere so akkuraat<br />
moontlik te identifiseer sodat<br />
seleksiebesluite sinvol geneem kan<br />
word.<br />
3. Om bestuurspraktyke te evalueer<br />
en seleksiebesluite te vergemaklik.<br />
4. Om die geleentheid te skep vir<br />
wetenskaplikes en telers om byeen<br />
te kom en sake van<br />
gemeenskaplike belang te<br />
bespreek. Die afgelope dekade of<br />
meer het die gesindheid van beide<br />
stoet- en kommersiële telers<br />
teenoor wetenskaplike hulpmiddels<br />
en tegnieke dramaties verander.<br />
Prestasietoetsing is een van die<br />
voortreflikste opvoedkundige<br />
mediums wat vandag in die<br />
vleisbedryf funksioneer.<br />
5. Om die ekonomiese voortreflikhede<br />
van die verskillende rasse en<br />
veranderings wat deur die jare<br />
plaasvind, te dokumenteer sodat dit<br />
vir die bedryf waardevolle inligting<br />
vir beplanning kan verskaf.<br />
6. Om in samewerking met die Suid-<br />
Afrikaanse Stam-boekvereeniging<br />
‘n geintegreerde rekenaarprogram<br />
daar te stel wat duplikasie uitskakel<br />
en die stoetbedryf op ‘n gesonder<br />
basis plaas.<br />
Basis waarop Prestasietoetsing<br />
berus<br />
1. Individuele diere verskil geneties<br />
wat hul groeivermoë, groeikurwe,<br />
patroon van ontwikkeling, tydperk<br />
tot geslagsrypheid,<br />
voeromsetverhouding, ens. Betref.<br />
2. Daar bestaan dramatiese<br />
produksieverskille tussen diere wat<br />
uiterlik eenders vertoon. Dit word
veral by FASE C toetssentrums<br />
gereeld opgemerk.<br />
3. Die meeste eienskappe by<br />
vleisbeeste is middelmatig tot hoog<br />
oorerflik. Verskeie komponente van<br />
reproduksie is hoog oorerflik. Die<br />
dier se eie prestasie is dus ‘n goeie<br />
aanduiding van sy teelwaarde.<br />
4. Melkproduksie is ‘n eienskap met ‘n<br />
hoë herhaalbaarheid. Seleksie vir<br />
koeidoeltreffendheid, wat gewoonlik<br />
met verhoogte melkproduksie<br />
gepaard gaan, kan dus met groot<br />
suskes gedoen word.<br />
5. Navorsingsresultate en gegewens<br />
uit die praktyk toon besondere<br />
vordering, in ‘n aantal eienskappe,<br />
deur die toepassing van<br />
prestasietoetsing as seleksiehulpmiddel.<br />
Eienskappe wat aandag geniet in<br />
Prestasietoetsing<br />
Die belangrikste eienskappe wat<br />
produksie doeltreffendheid beïnvloed<br />
word deur die skema geevalueer, en is:<br />
1. Vrugbaarheid<br />
2. Moederseienskappe<br />
3. Koeidoeltreffendheid<br />
4. Groei (intensief en ekstensief)<br />
(a) Geboortemassa<br />
(b) Groei per dag van ouderdom<br />
(c) Naspeen groei<br />
5. Voeromset<br />
6. Skelet ontwikkeling<br />
7. Karkaseienskappe<br />
Hierdie eienskape geniet aandag onder<br />
verskillende fases van die skema.<br />
22<br />
Uiteensetting van die Skema<br />
Die Skema behels vyf fases, waarvan<br />
Fases A en B (kudde evaluering onder<br />
heersende plaastoestande) die basis<br />
vorm, terwyl Fases C en D groeitoetse<br />
van jong bulle behels. In Fase A en B<br />
wor geen vergelykings tussen kuddes<br />
getref nie aangesien toestande van<br />
plaas tot plaas verskil.<br />
Fase A: Koeikudde Evaluasie<br />
(Verpligtend)<br />
Die moedereienskappe van die koei<br />
word d.m.v. die massa van haar kalf<br />
geevalueer. Die koei se<br />
reproduksieprestasie en<br />
doeltreffendheid van produksie word<br />
ook geevalueer.<br />
1. Geboortemassa: (Opsioneel)<br />
Voorgeboortelike groei word deur<br />
hierdie meting geevalueer en is<br />
belangrik vir die volgende redes:<br />
(a) Die rol wat dit speel by die<br />
kalfprobleme en kalfmortaliteit<br />
(b) Die rol wat dit speel by<br />
uterusherstel na kalwing;<br />
(c) Korrelasie met alle massas en<br />
groeivermoë tot volwassenheid;<br />
(d) Dit speel ‘n belangrike rol by<br />
akkuraatheid van<br />
indeksbepaling;<br />
(e) Seleksie vir groei kan<br />
veroorsaak dat geboortemassa<br />
toeneem.<br />
2. Voorspeenmassa: (Opsioneel)<br />
Hierdie massa is die beste massa<br />
om die melkproduksie van die koei<br />
te bepaal.
3. Speenmassa: (Verpligtend)<br />
Die speenmassa van ‘n kalf<br />
weerspieël die melkproduksie van<br />
die koei sowel as die groeivermoë<br />
van die kalf.<br />
Die beenmassa van ‘n koei se kalf<br />
is ‘n herhaalbare eienskap. Dit<br />
beteken dat die koei, met ‘n redelike<br />
mate van akkuraatheid, geevalueer<br />
kan word op die prestasie (groei)<br />
van haar eerste kalf.<br />
4. Koeimassa: (Opsioneel)<br />
Indien die koei massa en<br />
geboortemass (van die kalf) wel<br />
geneem word kan ‘n koei-kalf<br />
verhouding en ‘n<br />
koeidoeltreffendheidsindeks bepaal<br />
word.<br />
Fase B: Massatoename naspeen<br />
(Verpligtend)<br />
Die massa van verse, osse en jong<br />
bulle wat ekstensief grootgemaak word,<br />
word met gereelde tussenposes vanaf<br />
speen- tot teelouderdom gemeet.<br />
Ons sien dus dat in hierdie fase<br />
hoofsaaklik groei van die diere na<br />
speen gemeet word. Aangesien dit<br />
groei onder ekstensiewe toestande<br />
meet, speel aanpassingsvermoë van<br />
die dier hier ‘n rol.<br />
Fase C: Gestandaardiseerde<br />
Groeitoetse (Opsioneel)<br />
Hier word twee verskillende groeitoetse<br />
gedoen, nl.:<br />
C1: Groeitoetse by departementele<br />
toetssentrums en<br />
23<br />
C2: Groeitoetse by nie-departementele<br />
toetssentrums.<br />
In hierdie fase word jong bulle onder<br />
gestandaardiseerde intensiewe<br />
toestande by sentrale toetssentrums<br />
oor ‘n tydperk van 112 dae getoets.<br />
Die gelangrikste eienskap wat aandag<br />
geniet is:<br />
1. Die gemiddelde daaglikse toename<br />
oor toetsperiode (GDT) ADG.<br />
2. Voeromset verhouding (VOV),<br />
d.w.s. die hoeveelheid voer gevreet<br />
om ‘n kg gewig aan te sit (FC).<br />
3. Groei per dag van ouderdom (GDO)<br />
Ander mates wat aan die einde van die<br />
toets geneem word is:<br />
1. Skouerlengte<br />
2. Liggaamslengte<br />
3. Skrotumomvang<br />
4. Veldikte<br />
Fase D: Groeitoetse van Jong Bulle<br />
(Opsioneel)<br />
Hierdie wor drie verskillende<br />
groeitoetse gedoen, naamlik:<br />
D1: Op die plaas enkelkudde<br />
groeitoets<br />
D2: Gesentraliseerde veelkudde<br />
groeitoets<br />
D3: Verkorte enkel of veelkudde<br />
groeitoets<br />
Onder Fase D toetsing word die<br />
naspeen-groeivermoë van jong<br />
bulkalwers deur middel van groeitoetse,<br />
onder gekontroleerde toestande op die<br />
plaas van ‘n lid of by die geriewe van ‘n<br />
privaatinstansie, geevalueer. Om ‘n<br />
Fase D groeitoets te doen moet daar<br />
ten minste 15 bulkalwers per ras in die<br />
groeitoets opgeneem word. Ten minste
5 van hierdie bulkalwers moet<br />
registreerbaar wees.<br />
Fase D1 en D2 toetse strek oor ‘n<br />
minimum van 140 dae en ‘n maksimum<br />
van 365 dae met ‘n<br />
aanpassingsperiode wat wissel tussen<br />
21 en 90 dae. Die ouderdomme van<br />
die bulle in die toetsgroep mag nie met<br />
meer as 120 dae verskil nie en die<br />
oudste bul mag nie ouer as 365 dae<br />
wees nie. Die toetse word gewoonlik<br />
ekstensief, met byvoeding soos die<br />
teler dit verkies, gedoen. Vir die toets,<br />
om amptelik te wees, moet die bulle ten<br />
minste ‘n gemiddelde daaglikse<br />
toename van tussen 450g en 650g<br />
afhangend van die ras wissel,<br />
handhaaf.<br />
Fase D3 toetse strek oor ‘n 112 dae<br />
periode, waartydens die bulle aan ‘n<br />
kragvoerrantsoen onderwerp word. Die<br />
aanpassingsperiode sal wissel tussen<br />
28 en 35 dae. Die oudste bul in die<br />
toetsgroep mag nie ouer as 270 dae<br />
met die begin van die aanpassing wees<br />
nie. Vir die toets om amptelik te wees,<br />
moet die bulle ten minste ‘n gemiddelde<br />
daaglikse toename wat tussen 1000g<br />
en 1400g, afhangend van die ras<br />
wissel, handhaaf<br />
Fase E: Karkasevaluasie<br />
(Opsioneel)<br />
Die kwalitatiewe karkaskomponente<br />
van die nageslag van ‘n bul word<br />
geevalueer. Vir hierdie fase moet daar<br />
15 nageslagte van ‘n spesifieke bul<br />
geslag en geevalueer word.<br />
24<br />
Punte van belang<br />
Prestasietoetsing is slegs ‘n seleksie<br />
hulpmiddel en moetin balans met ander<br />
hulpmiddels gebruik word.<br />
Prestasietoets resultate moet dus met<br />
diskresie gebruik word en visuele<br />
beoordeling van funsionele<br />
doeltreffendheid sowel as die produksie<br />
sistem moetin aanmerking geneem<br />
word.<br />
Prestasietoetsing is nie die enigste<br />
seleksie metode beskikbaar nie, maar<br />
dit verskaf die mees akkurate metode<br />
om beter en swakker diere te<br />
identifiseer.<br />
Sekere verwerkingsprosedures van die<br />
skema gee voorkeur aan maksimum<br />
groei. Die dier met die beste<br />
groeivermoë sal dus die hoogste indeks<br />
behaal. Telers is geneig om te aanvaar<br />
dat die dier met die hoogste indeks die<br />
aangewese een vir elke situasie is. Dit<br />
is egter nie noodwendig die geval nie.<br />
Telers moet dus die toestande<br />
waaronder die dier moes presteer ook<br />
in ag neem.

MARKETING REGISTERED CATTLE<br />
Many factors are involved in effectively<br />
marketing anything – whether it be<br />
cars, clothing or registered cattle. What<br />
follows are a few ways which seem<br />
common it all successful stud breeding<br />
programmes.<br />
KNOW YOUR MARKET - perhaps<br />
more than any other thing, this is a<br />
must. It is futile to spend time and<br />
money producing cattle for which there<br />
is no market. Successful breeders first<br />
find out what is needed, and then<br />
produce for that need.<br />
First you should try to raise an<br />
acceptable product to market. One that<br />
is acceptable to you in performance,<br />
pedigree, type and adaptable to your<br />
own environment. It is very hard to<br />
convince someone else that your<br />
programme is good if you are not first<br />
satisfied.<br />
The big question is, are you producing<br />
for the purebred stud market, the<br />
commercial cattleman or both? Some<br />
breeders can have the best of both<br />
worlds – work on the one that fits your<br />
programme. Make sure that your cattle<br />
fit the need, then start a good<br />
marketing programme.<br />
There are many ways to promote<br />
registered cattle. Naturally an all year<br />
advertising campaing in the smalls<br />
column as well as in breed journals is<br />
ideal. Shows, sales and field days are<br />
also good promotion tools. Regardless<br />
of the way that you promote cattle,<br />
always keep one thing in mind. You’re<br />
still producing for the man that uses<br />
your product.<br />
Any success that you have as a<br />
breeder must stem from the fact that<br />
you breed and select cattle to fit your<br />
marketing area. Then you should try to<br />
feed and handle them in a really<br />
practical way so that the production and<br />
performance records are meaningful.<br />
Your customers should then be<br />
more interested in the cattle than in<br />
promotion<br />
The local market should always be your<br />
top priority, even though you might<br />
have sold to all four provinces and to<br />
neighbouring countries, you will find<br />
that your most dependable market is<br />
your home province. In fact, the most<br />
successful outfits that stay in business<br />
over a period of time have built their<br />
business – at lesat the beginnings, the<br />
rudiments, by selling to their<br />
neighbours. One can safely say, that<br />
with all the tools available to breeders<br />
today to assist them with their breeding<br />
programmes, a superior merchandiser<br />
with minimal breeding ability will be<br />
able to survive the financial realities of<br />
the business better than a superior<br />
breeder wth minimal merchandising<br />
ability.<br />
RECOGNISE WHAT YOU HAVE – with<br />
todays artificial insemination and, even<br />
more lately, embryo transfer usage,<br />
every breeder has equal access to the<br />
industry’s leading bloodlines, so it takes<br />
more than just a popular pedigree to<br />
command the top price. Successful<br />
breeders with a track record of effective<br />
marketing have travelled widely studied<br />
the difference between “good” and<br />
“great” and learned to recognize it in<br />
their product.
PROMOTE YOUR PROGRAMME – in<br />
the highly competitive environment of<br />
the purebred cattle business today, if a<br />
breeder doesn’t enjoy marketing his<br />
product, then his chances for success<br />
in his overall programme are slim.<br />
Try to let people know your philosophy<br />
of breeding cattle and tell them<br />
everything that you know about your<br />
herd sires and A.I. sires – because you<br />
may have the greatest batch of calves<br />
in the history of your breeding<br />
programme, but will not make any<br />
difference if those looking for a new<br />
herd sire, ranch bull or replacement<br />
heifers, don’t know about them.<br />
It’s the people in the livestock industry<br />
wyo consistently sell their cattle for a<br />
premium that are the breeders who<br />
enjoy selling.<br />
Producing a quality product is the goal<br />
of any business. All too often in the<br />
stud industry breeders forget the most<br />
important first step – MARKET<br />
RESEARCH – they design and produce<br />
a product and then begin searching for<br />
someone to buy it.<br />
More often than not, stud breeders<br />
expect a promotional programme to<br />
compensate for a poor product or for<br />
inadequate preparation. Without a<br />
quality product and a high level of<br />
service, the sales you make are bound<br />
to “one-time” customers.<br />
Building a satisfied and loyal customer<br />
base should be the ultimate goad.<br />
Promotion requires several important<br />
steps. First identify the positive things<br />
that can be said about your product.<br />
26<br />
Then plan a promotional programme to<br />
convey these facts to potential<br />
customers. Advertising, sale<br />
catalogues, personal contact and direct<br />
mailings are all effective segments of a<br />
total marketing strategy.<br />
The easiest way to sell cattle is to sell<br />
them the way you would like to buy<br />
them. That is producing a good<br />
product and promoting it accurately and<br />
completely. Try to emphasize the<br />
positive things about your cattle,<br />
because if you are not excited about<br />
them then you certainly can’t expect<br />
anyone else to be.<br />
Possibly one of the most neglected<br />
areas in the Stud Industry is that sellers<br />
do not help new breeders with their<br />
problems when they start off. It is all<br />
too easy to say thank you and walk<br />
away after a sale is made. The<br />
problem lies in the selling experienced<br />
breeders a product and then new<br />
breeders find their enthusiasm quickly<br />
drains away when they don’t know how<br />
to handle routine problems. To combat<br />
this, the smaller seller should give this<br />
new breeder management time. The<br />
new breeder will then feel well<br />
supported in his or her new endeavour<br />
and more often than not, will be come a<br />
REPEAT BUYER.<br />
Follow-up and making sure the cattle<br />
meet you customers expectations is<br />
most important because your<br />
operation should depend on repeat<br />
customers not a new crop of buyers<br />
every year.<br />
Travelling as much as possible to<br />
gather knowledge about what is<br />
happening in the breed and with your<br />
own herd, and to enjoy the friendship of
established and new breeders alike<br />
should be important to you.<br />
In an auction situation the breeder’s<br />
catalogue is the true test. Are you<br />
willing to publish ALL the performance<br />
on your sale cattle, or are certain ratios<br />
or calving dates conveniently left out?<br />
May there are no figures at all. Nothing<br />
disappoints buyers more than to get a<br />
catalogue from a good production outfit<br />
and find that the only figures included<br />
are the lot numbers and the fact that a<br />
grand old cow that you sold to<br />
someone else brought in R10000.00 on<br />
that breeders sale three years ago!!! If<br />
the breeding and the performance<br />
behind the offering looks good, then the<br />
buyer will go to the effort of contacting<br />
the breeder for more information.<br />
Don’t underestimate the value of a<br />
phone call. Remember no one has<br />
ever bought a bull they didn’t know<br />
existed.<br />
A few basics I paperwork are important.<br />
Always write “thank you’s” to your cattle<br />
buyers. You should have a card file on<br />
buyers which includes a record of all<br />
purchases made, the dates and<br />
amounts. This information on past<br />
purchases will help to tell you what a<br />
customer will want. Naturally this file<br />
also serves as a mailing list.<br />
27<br />
When your cattle are sold, back them<br />
with a guarantee. Something like:<br />
“Your satisfaction guaranteed, or your<br />
money back”. This indeed will let your<br />
buyers know that you are sincere in<br />
your desire to please them.<br />
Developing customer confidence is the<br />
key to successful marketing. They<br />
must have confidence in you, your<br />
programme and the cattle being<br />
offered.<br />
In summary, effective marketing is a<br />
matter of knowing what to produce for<br />
the market you have; recognizing<br />
when you have a really great one to<br />
sell; promoting the fact that you have<br />
great ones to sell; and properly<br />
presenting them tot he prospective<br />
buyer.<br />
A reputation for honesty and reliability,<br />
standing behind the cattle you sell, and<br />
follow-up with your customers are also<br />
necessary ingredients in being a<br />
successful merchandiser.<br />
In shot, “successful marketing is like a<br />
good golf swing: it’s the follow through<br />
that helps improve the distance …”<br />
and in the final analysis, each breeder<br />
is responsible for his own success. He<br />
can draft some help, but it is his own<br />
initiative and ingenuity that makes a<br />
successful merchandising prgoramme.<br />
It’s the FOLLOW THROUGH – Think<br />
about it!

SAMEVATTING VAN BASIESE BEGINSELS VAN<br />
BEOORDELING<br />
VAN BEESTE<br />
Deur H.M. Seyfferdt<br />
Dit moet altyd onthou word dat waar of<br />
wanneer u ookal optree as<br />
beoordellaar, u besig is om<br />
opvoedings- en onderrigwerk te verrig.<br />
U is besig om die toeskouers en<br />
vertoners te toon wat korrek is en wat<br />
nie.<br />
Daarom is dit noodsaaklik da u u<br />
kennis van beeste in die algemeen,<br />
asook van die <strong>Sussex</strong>-ras in die<br />
besonder, gedurig sal uitbou.<br />
Om objektief te beoordeel, moet u oor<br />
die nodige kennis beskik, maar u moet<br />
ook eerlik wees. U mag nie toelaat dat<br />
enigiets of iemand, behalwe wat u sien<br />
en waarneem in die diere, u besluite<br />
beïnvloed nie. U moet ook nooit die<br />
ekonomiese faktore of eienskappe uit<br />
die oog verloor nie. U kennis moet oor<br />
die volgende beskik:<br />
1. Die samestelling van die bees.<br />
2. Die korrekte benaming van die<br />
verskillende liggaamsdele.<br />
3. U moet die korrekte benaming van<br />
die foute ken.<br />
4. U moet die standaard van<br />
voortreflikheid ken.<br />
Ons wil nie nou op al bogenoemde<br />
punte ingaan nie, maar tog kortliks vir u<br />
‘n paar foute noem waarna u moet<br />
oplet wanneer u beoordeel:<br />
(a) Voorbene: X-benig or<br />
krombenig<br />
(b) Agterbene: Krombenig,<br />
koeihakkig, sekelhakkig,<br />
regophakkig<br />
(c) Pote: Te regop, te slap,<br />
deurtrap<br />
(d) Kop: Skewe of gedraaide<br />
neusbeen, kort bek, lang<br />
onderkaak<br />
(e) Lende: Swak lende, swak rug en<br />
lende aansluiting<br />
(f) Grootte: Vir ouderdom<br />
Dit is egter belangrik dat u weet<br />
waarvoor die ras geteel word, m.a.w.<br />
die doel van die ras, sodat u veral ag<br />
kan slaan daarop dat die dier aan sy<br />
doel beantwoord. Die <strong>Sussex</strong> is ‘n<br />
vleisras wat funksioneel moet wees.<br />
Om in kort alles saam te vat:<br />
Om ‘n beoordelaar te word, moet u leer<br />
want u moet oor kennis beskik. Leer uit<br />
boeke, leer van mede-telers en veral<br />
beoordelaars, leer op skoue en leer<br />
dan om op grond van u eie kennis die<br />
verskille in diere raak te sien, die<br />
verskille teen mekaar op te weet en te<br />
besluit hoe die verskille tussen diere<br />
teen mekaar opweeg.
From experience, I have found that<br />
the number of an animal most easily<br />
read, is the tattooi above the top vein<br />
of the ear.<br />
Step one is therefore to put the year<br />
letter plust the sequence number in<br />
the top half of your tattooi pliers and<br />
the herd designation letters in the<br />
bottom half o f your pliers, for<br />
example:<br />
Voorvoegsel + Jaartal + volg<br />
nommer.<br />
CN 06 0100<br />
If your are not sure how the numbers<br />
will look when tattooed, use a pice of<br />
paper and clamp it with the pliers.<br />
The best tattooing ink is ZEBO<br />
STOVE POLISH or A BLACK LEAD<br />
IN SUSPENSION.<br />
The calf to be tattooed, must be held<br />
firmly. The tattoo in the pliers must<br />
then be thoroughly wet with the<br />
tattooi ink. (An old toothbrush is the<br />
ideal applicator).<br />
The pliers are then postioned in the<br />
calf’s LEFT EAR WITH THE TOP<br />
29<br />
THE ART OF TATTOOING<br />
VEIN OF THE EAR BETWEEN THE<br />
NUMBER AND THE HERD<br />
DESIGNATION LETTERS. Making<br />
sure that they are not too near the<br />
end of the ear or too deep in towards<br />
the head. THE PLIERS THEN ARE<br />
CLOSED WITH A HARD, POSITIVE<br />
ACTION AND HELD IN CLOSED<br />
POSITION FOR AT LEAST THIRTY<br />
(30) SECONDS. This allows the<br />
holes to remain open for a while after<br />
the pliers have been opened and<br />
removed.<br />
Immediately after removing the<br />
pliers, the TATTOO INK SHOULD<br />
BE THOROUGHLY WORKED IN<br />
WITH THE SAME TOOTHBRUSH<br />
THAT IS WET WITH TATTOO INK.<br />
SPEND AT LEAST FIFTEEN (15()<br />
SECONDS BRUSHING THE INK<br />
INTO THE TATTOO.<br />
The animal is then released and if<br />
possible, left for at least three weeks<br />
before reading thenumber in the ear.<br />
If one takes care, the numbers in the<br />
ear will be clearly visible even when<br />
the animal is very old.

VOEDING VAN VLEISBEESTE EN GROOTMAAK VAN<br />
BULLE<br />
Deur Willie Grobler van Rumevite<br />
Aangesien die landsoppervlakte vir<br />
landbougebruik jaarliks verminder en<br />
die bevolkingsgetalle jaarliks groei,<br />
word daar ‘n groter druk op , veral die<br />
veeboer, geplaas om meer te<br />
produseer. Dit kan slegs geskied<br />
indien die beginsels en praktyke van<br />
voeding gerespekteer en nagekom<br />
word.<br />
VOEDINGSPRAKTYKE<br />
Dierevoeding word hoofsaaklik in drie<br />
praktyke ingedeel, naamlik aanvullende<br />
voeding, byvoeding en volvoeding.<br />
Elkeen van hierdie praktyke het ‘n<br />
spesifieke doel en bepaalde reëls<br />
waaraan die praktyk moet voldoen om<br />
as sulks geklas te word.<br />
(a) Aanvullende voeding:<br />
Dit is die maksimum ruvoer- of<br />
weidingsinname. Lekinname maak<br />
minder as 10% van die dier se<br />
daaglikse inname uit.<br />
(b) Byvoeding:<br />
Wanneer ruvoer0 of<br />
weidingsinname nie maksimum kan<br />
wees nie, hetsy weens tekort of<br />
swak waarde wat inname beperk,<br />
word kragvoer volgens behoefte<br />
gegee. Hierdie is ‘n praktyk wat<br />
baie gereeld, veral in die kouer dele<br />
van Suid-Afrika, toegepas word<br />
deur bv. Voorsiening van heel<br />
gemaalde mielieplante.<br />
(c) Volvoeding:<br />
Hierdie praktyk is vanselfsprekend.<br />
Maksimum kragvoerinname en<br />
ruvoer slegs om gesonde<br />
rumenfunksie te verseker.<br />
Die algemene praktyk van afronding<br />
van beeste en dus ook van bulle in<br />
krale of stalle, val in hierdie praktyk.<br />
Al hierdie verskillende praktyke het ook<br />
spesifieke beginsels wat geken en<br />
daarom gerespekteer behoort te word.<br />
Hiervan is, vir hierdie artikel, die<br />
beginsels van lekaanvulling die<br />
belangrikste.<br />
(a) Aanvullende voeding of lekke moet<br />
die voedingstekorte in die dieet<br />
balanseer en aanvul sodat meer<br />
ruvoer ingeneem kan word en ook<br />
beter benut kan word.<br />
(b) Lekke moet aanvullende tot die<br />
weiding wees en dit nooit vervang of<br />
die vrywillige inname beperk nie.<br />
Ruvoer-inname moet die maksimum<br />
wees.<br />
(c) Die norm en samestelling van die<br />
lek moet gelykmatig en<br />
gekontroleerde vrywillige inname<br />
verseker.<br />
In die voeding van beeste kom<br />
verskillende knelpunte voor. Soos o.a.<br />
lae en selfs onverteerbaarheid van<br />
wintergrasse, wat ‘n direkte tekort aan<br />
inname van energie veroorsaak.<br />
Tekort aan proteïen in die winter en laat<br />
somer op natuurlike weidings, asook<br />
marginale fosfor tekort in die somer.<br />
Van hierdie knelpunte kan reggestel
word deur gesonde voedingspraktyke<br />
toe te pas, bv. Lekaanvulling.<br />
Hierdie lekaanvulling moet genoeg<br />
wees om tekorte aan te vul, maar in die<br />
regte verhouding en ook op die regte<br />
tyd. Hierdie aanvullende voeding<br />
behoort alle essensiële voedingstowwe<br />
te bevat, maar ook baie belangrik is dat<br />
hulle gebalanseerd t.o.v. mekaar moet<br />
wees. ‘n Motor se enjin bevat water,<br />
olie en petrol. Nie een van hulle is, vir<br />
doeltreffende werking, belangriker as ‘n<br />
ander een nie, maar ook slegs indien<br />
hulle in die regte verhouding is.<br />
Aanvullende voeding moet net genoeg<br />
wees om die einddoel te bereik, en<br />
moet ekonomies wees.<br />
Die belangrikheid van die balans van<br />
voedingstowwe in aanvullende voeding<br />
asook ‘n bepaling van die behoefte per<br />
dag van verskillende diere, hoe dit deur<br />
natuurlike weiding aangevul word, wat<br />
die tekorte is en hoe dit dan deur<br />
aanvullende voeding reggestel kan<br />
word. Indien hierdie tekorte nie betyds<br />
reggestel kan word nie, mag ons<br />
hewige gewigsverliese ondervind wat<br />
dalk aanleiding kan gee tot verlaagde<br />
kalf en speenpersentasies.<br />
Voordele:<br />
Deur die gewendte teikenmassa by die<br />
aanvang van die dekseisoen te bereik,<br />
kan die volgende voordele in die hand<br />
gewerk word:<br />
- Hoë kalfpersentasie<br />
- Hoër kalwingstempo<br />
- Beter kan vir herbesetting<br />
- Korter intekalfperiode<br />
- Hoër speenmassa<br />
- Hoër koeimassa<br />
31<br />
Teikenmassa by koeie is per definisie<br />
die gewig wat ‘n koei met paring het,<br />
wat haar die grootste kans gee om<br />
beset te raak.<br />
Slaggate by aanvullende voeding:<br />
Onnodige aanvulling of wanbalans<br />
tussen voedingstowwe wat aangevul<br />
word:<br />
1. Vervangingsvoeding: Inname<br />
onderdruk natuurlike weidingslus of<br />
maak ‘n te groot deel van daaglikse<br />
dieet uit.<br />
2. Probleme met innames wat te hoog<br />
of te laag kan wees, kan die<br />
volgende oorsake onderligged hê:<br />
(a) Lek is nie deurentyd beskikbaar<br />
nie en gulsigheid of southonger<br />
word ondervind.<br />
(b) Die lek is of te smaaklik, het dalk<br />
te veel meel in, of is onsmaaklik<br />
met ‘n hoë insluiting van sout.<br />
(c) Weens ‘n tekort aan ruvoer kan<br />
lek innames hoog wees en<br />
indien goeie ruvoer in oorvloed<br />
beskikbaar is, sal innames laag<br />
wees. Lekinnames in nuwe<br />
kampe en mielielande kan<br />
aanvanklik laag wees, maar<br />
verhoog langsaam namate<br />
ruvoer verminder.<br />
(d) Die aantal diere per lekpunt het<br />
ook ‘n invloed op die lekinname.<br />
Dominansie in ‘n kudde<br />
veroorsaak dat party diere meer<br />
vreet en swakkeres wat dit juis<br />
nodig het, nie vrye toegang het
tot lek nie. ‘n Ideaal is 12 – 15<br />
beeste per lekpunt.<br />
(e) Die afstand wat lekke vanaf die<br />
watersuipings geplaas word, het<br />
baie beslis ‘n invloed op inname.<br />
Verder vanaf die water gee laer<br />
innames terwyl lekpunte nader<br />
aan die suipings hoër innames in<br />
die hand werk.<br />
(f) Die formulasie en fisiese<br />
voorkoms van lekke het ook ‘n<br />
invloed op die hoër of laer<br />
innames. Los lekke word meer<br />
geredelik as blokke ingeneem,<br />
maar blokke se inname is meer<br />
gelykmatig.<br />
(g) Een van die grootste oorsake<br />
van te hoë innames is dat<br />
lekaanvulling te laat in die winter<br />
begin. Diere het reeds ‘n<br />
agtersand en oormatige<br />
behoefte aan lek bereik, voordat<br />
aanvulling begin.<br />
Grootmaak en voeding van bulle:<br />
Meer as 95% van alle bulle word aan<br />
kommersiële beesboere verkoop. Die<br />
probleem is dat ±76% van all bulle voor<br />
of op 24 maande van eienaar verander.<br />
Die praktyk het bewys dat kommersiële<br />
bulkopers, veral as hy ‘n bietjie hoë<br />
prys betaal het vir ‘n bul, geneig is om<br />
hom baie hard te laat werk, om<br />
daardeur sy geld te probeer verhaal.<br />
Hierdie jong bul ondergaan nou, nadat<br />
hy gekoop is, ‘n paar strawwe toetse.<br />
(a) Hy moet aanpas in die omgewing<br />
waar hy nou gaan loop.<br />
32<br />
Byvoorbeeld vanaf die Transvaal<br />
Hoëveld na die Noordkaap.<br />
(b) Hy kry nie meer die hoë peil van<br />
voeding waaraan hy vir ‘n lang tyd<br />
gewoond was nie, omdat hy ‘n<br />
sekere grootte en gewig moes<br />
behaal om verkoopbaar te wees.<br />
(c) Hy moet koeie dek, dit is waarvoor<br />
hy gekoop is. (Verbeter die<br />
genepoel en kry vroulike diere<br />
dragtig is die algemene<br />
uitgangspunt).<br />
(d) Meeste rasse sny tande tussen die<br />
ouderom van 21 en 30 maande.<br />
Met al hierdie omstandighede in ag<br />
geneem, kan so ‘n jong bul, indien hy<br />
nie goed versorg word nie, baie gou<br />
soos ‘n wrak daar uit sien. Die direkte<br />
gevolg is ‘n bul wat ‘n lang herstel<br />
period nodig het, en moontlik ‘n swak<br />
naam aan die ras asook die teler<br />
besorg.<br />
Die wenslikste sou wees om hulle op ‘n<br />
hoër ouderdom te bemark sodat hulle<br />
‘n langer tyd gehad het om nader aan<br />
hulle volwasse gewig te kon kom. Die<br />
ekonomie van so ‘n praktyk kom egter<br />
hier sterk ter sprake aangesien telers<br />
bulle langer sal moet hou en voer.<br />
Die verandering kan egter goedkoper<br />
geskied, mits die volgende punte in ag<br />
geneem word:<br />
(a) Werk behoorlike doelwit gewigte uit<br />
vir bulle teenoor hulle ouderdomme<br />
bv. Speen, 12 maadne, 18 maande,<br />
24 maande en 30 maande.
(b) Gee minder voer oor ‘n langer<br />
tydperk om net hierdie<br />
doelwitgewigte te behaal.<br />
(c) Indien regstellings gemaak moet<br />
word, bestaan daar meer tyd<br />
daarvoor.<br />
(d) Hou bulle nader aan die natuurlike<br />
omstandighede, veral waar hulle<br />
moet gaan werk, naamlik die veld.<br />
Die moontlikheid dat hierdie bulle die<br />
probleem kan optel wat jonger teëkom,<br />
is baie skraler.<br />
Die resultaat – ‘n Tevrede Bulkoper!<br />
33<br />
Die bulkoper wat weer en weer by jou<br />
bulle aankoop, is die enigste maatstaf<br />
om te bepaal hoe suksesvol jy as<br />
bulteler is.<br />
Kwaliteit is belangrik!!!<br />
Hierdie is ‘n aanhaling van Ruskin:<br />
KWALITEIT IS BELANGRIK<br />
Daar is bykans niks ter wêreld wat nie<br />
deur iemand effens swakker vervaardig<br />
en effens goedkoer aangebied kan<br />
word nie. Mense wat slegs die prys<br />
van ‘n artikel in ag neem, is hierdie<br />
vervaardiger se wettige prooi.
VELD BULL POWER HAS THE<br />
COMPETITIVE EDGE<br />
Why a <strong>Sussex</strong> veld club? IN most veld<br />
clubs of today, <strong>Sussex</strong> are compared to<br />
large framed animals which appear to<br />
look better but do not necessarily<br />
perform better. The commercial buyer<br />
will not, or soon wil not, buy fat show<br />
ring finished bulls as the “crash” under<br />
commercial conditions.<br />
Our bull club will be unique in that we<br />
will incorporate growth tests under<br />
intensive, semi-intensive and extensive<br />
conditions, namely a ration test (official<br />
Phas D2) and a veld test on Highveld<br />
veld and Smutsfinger grass. This<br />
determines the bulls hereditary<br />
potential for weaners ending up in<br />
feedlots, and the adaptability for future<br />
commercial cows. This test is<br />
approved by the <strong>Sussex</strong> <strong>Cattle</strong><br />
<strong>Breed</strong>ers <strong>Society</strong>.<br />
Performance data is often overlooked<br />
but definitely plays an important role in<br />
the future of a successful beef farmer.<br />
A combination of data and<br />
conformation in a selected bull is 50%<br />
34<br />
of the genetic material of your fuure<br />
herd.<br />
A comparison of bulls throughout the<br />
country can be made under the same<br />
conditions. The test will be carried out<br />
on Vogelsfontein, Randfontein District<br />
on severe Redwater and Gallsickness<br />
veld and will be completed over a<br />
period of 18 mnths. There will be 12<br />
monhs of testing under commercial<br />
conditions, followed by rounding off for<br />
an auction.<br />
All bulls are sold under the auspices of<br />
the <strong>Sussex</strong> <strong>Society</strong>.<br />

VELDBUL HET DIE BEMARKBARE<br />
VOORDEEL<br />
Is ‘n <strong>Sussex</strong> Veldbulklub nodig? In die<br />
huidige veldbul klub’s word <strong>Sussex</strong> met<br />
groot raam rasse vergelyk, wat soms<br />
beter lyk, maar nie noodwending beter<br />
presteer nie. Die kommersiële koper<br />
sal nie of sal binnkort nie vet skou bulle<br />
koop nie, want onder kommersiële<br />
toestande gaan hulle agteruit.<br />
Ons Veldbulklub sal uniek wees met<br />
betrekking ot die inluyf van groei toetse<br />
onder intensief, semi-intensief en<br />
ekstensiewe toestande, naamlik<br />
rantsoen toets (offisiële Fase D2) en<br />
veld toets op die Hoëveld en<br />
Smutsvinger gras. Dit bepaal die<br />
oorerflike potensiaal vir voerkalwers,<br />
wat in die voerkraal eindig, sowel as die<br />
aanpasbaarheid van toekomstige<br />
kommersiële koeie. Hierdie toetse is<br />
deur die <strong>Sussex</strong> Beestelers<br />
Genootskap goedgekeur.<br />
Prestasie data word dikwels misgekyk,<br />
maar speel ‘n belangrike rol vir die<br />
suksesvolle beesboer. ‘n Kombinasie<br />
van prestasie data en bouvorm van ‘n<br />
uitgesoekte bul gee 50% van die<br />
35<br />
genetiese material van jou toekomstige<br />
kudde.<br />
‘n Vergelyking van bulle uit die hele<br />
land onder dieselfde toestande kan<br />
gemaak word. Die toets vind plaas te<br />
Vogelsfontein, Randfontein Distrik, op<br />
strawwe Rooiwater en Galsiekte veld,<br />
vir ‘n tydperk van 18 maande. Met 12<br />
maande onder kommersiële toestande<br />
en dan afgerond vir ‘n veiling.<br />
Alle bulle word deur die <strong>Sussex</strong><br />
Genootskap goedgekeur en onder hul<br />
beskerming verkoop.<br />

GUIDE TO SHOW JUDGING<br />
Judging <strong>Sussex</strong> <strong>Cattle</strong><br />
36<br />
1. PLIGTE VAN DIE BEOORDEELAAR VOOR BEGIN VAN BEOORDELING<br />
1.1 Bestudeer die pryslys indien beskikbaar om jou te vergewis van die klasse en<br />
voorwaardes.<br />
1.2 Meld aan ten minste ‘n halfuur voor begin van die beoordeling, by die hoof<br />
vee opsigter of verantwoordelike beampte. Dit is nie passend om die vorige<br />
dag of heelwat vroeër dieselfde dag op die skougronde te wees nie. As dit<br />
egter onvermydelik is, moet die beoordellaar weg bly van die beesstalle en<br />
die vertoners.<br />
1.3 Gewoonlik dra beoordelaars ‘n wit jas, maar dit is nie noodsaaklik nie. ‘n Lap<br />
om hande af te vee na hantering van die beeste en ‘n klein notaboekie en<br />
potlood kan nuttig wees.<br />
1.4 Bespreek met jou opsigter die procedure wat jy gaan volg, bv. hoe en waar jy<br />
die beeste gaan laat staan wannneer jy die plasing doen. Vind uit watter<br />
inligting beskikbaar sal wees ten opsigte van die diere: gewigte,<br />
kalwingsdatums, ens. Die aantal pryse wat toegeken word, moet ook<br />
vasgestel word. Vra die opsigter om ook uit te vind of daar enige diere<br />
vertoon sal word wat jyself geteel het. Indien wel, Sien paragraaf 7.2<br />
2. JUDGING PROCEDURE AND RINGCRAFT<br />
2.1 Ensure that the cattle parade in a clockwise direction with the handlers on the<br />
outside of the ring. If your steward can arrange it, it is useful to have the<br />
animals parade in order of age.<br />
2.2 Parade the cattle one or twice around the ring to gain a general impression.<br />
2.3 Select one animal to start, and examine it as follows:<br />
2.3.1 Ask the steward the animal’s age and (if available) its weight, or<br />
pregnancy status or calving record where applicable.<br />
2.3.2Let it walk towards you; examine the placement of its front legs, length of<br />
canon bone, shoulders, width of chest, head.<br />
2.3.3Stop the animal, and examine the head and jaw – but only if you suspect<br />
a fault, i.e. over / undershot jaw. There is nothing worse than a judge<br />
who opens the jaw of every animal in the ring.<br />
2.3.4From the side, handle the animal’s coat, and try to gain an impression of<br />
condition. Observe the length, topline, muscling (look particularly at the<br />
forearm) , legs and feet.<br />
2.3.5 From the rear, examine the animal’s reproductive organs and uder,<br />
hind legs, hindquarter, width and muscling.
37<br />
2.3.6 As the animal walks away, watch placement of its hind legs, its<br />
freedom of movement and balance. Assesss its size and growth.<br />
2.4 After this close examination, you should have an overall impression of the<br />
animal, together with a mental list of its strengths and weaknesses. Repeat<br />
the process with each animal in turn. The exhibitor deserves this courtesy<br />
from the judge, even in the case of animals which are obviously substandard.<br />
2.5 Skilled judges are able to indicate to the spectators that they have spotted a<br />
weakness on an animal. Try to put your hand on the problem area or in other<br />
ways to indicate to the spectators that you have seen the fault.<br />
2.6 Once you have examined each animal individually, let all the animals circle<br />
the ring once or twice. By now, you should have an idea of your placings.<br />
But it you are undecided, ask the steward to change the order to enable you<br />
to compare animals more easily. Do not waste too much time. Remember<br />
that first impressions are often the best, and that by delaying a decision for<br />
too long, you very often get into even worse trouble.<br />
2.7 Have the steward line up your selections in your order of preference; do not<br />
forget to line the animals up from the same end for each class.<br />
2.7 Compare the animals while they stand side by side. Do not hesitate at this<br />
stage to change the order if you are sure that you initial placing was wrong.<br />
But avoid continuous chopping and changing, especially with lower placings.<br />
Be thorough, but don’t waste too much time.<br />
2.8 It is always useful to parade the prize winners one more time before coming<br />
to a final decision.<br />
2.9 It there is a large class, it may be necessary to eliminate the worst animals,<br />
and let them go out of the ring before lining up your selections. It is in any<br />
case not necessary to place all the animals, it is usual to place one or two<br />
more than the number of available prizes, with the remainder being merely<br />
lined up behind the prize winners.<br />
2.10 It is not required that you award all the prizes available. If the standard is<br />
poor, you may decide for e.g. not to award a first prize. But this action should<br />
only be taken in extreme cases!<br />
2.11 Before indicating to the steward that you have finished, make a mental<br />
note of the reasons for your placings. Then while the tickets are written out,<br />
explain to the spectators why you have placed the animals in the order you<br />
have. Be brief, polite and considerate of the exhibitors, but be specific. If is<br />
not sufficient merely to say that “It is a very nice bull”! Apart from these<br />
remarks it is not wise to talk privately either to spectators or to the leaders.<br />
2.12 Apart from requests for information, or instructions concerning the<br />
parading and placement of animals, the judge should not discuss any animals<br />
with the steward.
3. KAMPIOENSKAPPE<br />
38<br />
3.1 Jy sal onthou word hoofsaaklik as gevolg van die kampioene wat jy selekteer.<br />
Meeste beoordelaars sal van die eerste klas af op soek wees vir ‘n moontlike<br />
kampioen, en wanneer die kampioenskap klas instep, het hulle klaar besluit.<br />
3.2 Dring daarop aan dat die diere instep in volgorde van ouderdom. Dit<br />
vergemaklik die vergelyking en identifisering van die diere. Alleenlik eerste<br />
pryswenners moet in die ring toegelaat word.<br />
3.3 Selfs as jy reeds voorheen besluit het, moet jy baie deeglik die diere weer<br />
ondersoek: die kampioenskap word nooit ligtelik toegeken nie.<br />
3.4 Nadat jy die kampioen geselekteer het, laat die dier wat tweede na die<br />
kampioen in sy klas gestaan het, ingebring word. Hierdie dier sal dan met die<br />
oorblywende eerste pryswenners vir die reserve kampioenskap meeding.<br />
3.5 Hierdie procedure word gevolg vir die junior en senior kampioenskappe – as<br />
daar geen groot kampioen aangewys word, word die junior in aanmerking<br />
geneem vir die senior kampioenskap.<br />
3.6 Oor die algemeen is dit raadsaam om in die kampioenskap klas voorkeur te<br />
gee aan ouer diere en in die geval van vroulike diere, aan diere wat alreeds<br />
gekalf het.<br />
4. GROEPKLASSE<br />
4.1 Maak seker van die presiese bewoording van elke klas in die pryslys, en<br />
beoordeel dit streng volgens die voorwaardes wat daar gestel word.<br />
4.2 Gewoonlik maak die voorwaardes melding van ‘n groep, paar of<br />
eenvormigheid. Dit beteken dat ‘n groep bestaande uit diere wat individueel<br />
swakker as die diere in ander groepe, nogtans ‘n klas kan wen.<br />
4.3 Groepe staan gewoonlik in lyn neus tot stert. Dring daarop aan dat die<br />
groepe ook moet stap – diere wat nie mooi in ‘n groep pas nie kan makliker<br />
uitgeken word wanneer hulle beweeg.<br />
4.4 Terwyl individuele diere ook vergelyk moet word, probeer om nie te veel tyd<br />
te mors nie, veral as jy alreeds al die diere in die individuele klasse beoordeel<br />
het.<br />
5. PERFORMANCE CLASSES<br />
5.1 At most shows, there is a special performance class for tested bulls: (Phase<br />
C and Phase D) visual appraisal counts 30% and performance 70%.<br />
5.2 All that is necessary is that the judge places the bulls in the normal way<br />
(without reference to their performance), and then assigns percentages to<br />
each bull. These percentages are then combined with the bulls average<br />
performance indices by the performance official to arrive at a final order.
39<br />
5.3 The major difficulty with performance classes is that it is sometimes possible<br />
for a substandard bull with exceptional performance to win the class. The<br />
rule here is that the judge during his visual appraisal is entitled to disqualify a<br />
bull for serious defects – and eliminates the bull from the prize winners<br />
(whatever his performance).<br />
5.4 The calculations are done in the following manner e.g.:<br />
Bull A – visual appraisal % 80% - 110% x 0.3 = 33.0<br />
Bull B 75% - 103% x 0.3 = 30.9<br />
Bull C 65% - 89% x 0.3 = 26.7<br />
Average: 73%<br />
Bull A – Ave Perf Indices 104 - 95% x 0.7 = 66.5<br />
Bull B 109 – 100% x 0.7 = 70.0<br />
Bull C 114 – 105% x 0.7 = 73.5<br />
Average: 109<br />
TOTAL PLACING<br />
Bull A 99.5 THIRD<br />
Bull B 100.9 FIRST<br />
Bull C 100.2 SECOND<br />
6. GENERAL<br />
6.1 Even a good judge cannot always please exhibitors and spectators. A<br />
judge’s only duty is to please himself. Remember that it is your opinion that<br />
has been asked for.<br />
6.2 A good judge will have a set of priorities by which he assesses animals: All<br />
faults are not equally serious. Be careful of an obsession of one particular<br />
strength. The following priorities can be used as a guide.<br />
6.2.1The first requirement of a registered <strong>Sussex</strong> is that the animal should<br />
be capable of breeding. Penalize any animal which shows signs of<br />
infertility, and give preference to females which are in calf or which<br />
have calved regularly. Pay attention to udders.<br />
6.2.2The second requirement for a breeding animal is that it should be able<br />
to move, so pay particular attention to legs and feet.<br />
6.2.3The third requirement is that the animal must be capable of producing<br />
beef. Growth and size are therefore important. But remember that the<br />
<strong>Sussex</strong> is a medium sized breed, and we are therefore not necessarily<br />
aiming at giants. Be careful of confusing beef with fat. The council<br />
has directed that any animal with more fat cover than a super should
40<br />
be discriminated against. Well filled hindquarters may indicate<br />
overfeeding rather than good muscling. Remember too that a tall<br />
animal rarely has great width of hindquarter; bulging muscles often<br />
indicate short bones.<br />
6.2.4The fourth major requirement is that the animal should show signs of<br />
adaptability. A smooth glossy coat is a must and the animal should be<br />
alert and fit.<br />
7. PROBLEEMGEVALLE<br />
7.1 Wat word gedoen met ‘n dier wat tekens van beserings wys? As dit ernsti<br />
is, moet die mening van ‘n veearts aangevra word. Maar in elk geval die<br />
reel is dat jy die dier moet beoordeel soos hulle die dag van die beoording<br />
vertoon word: ‘n beseerde of anders ongesonde dier moet gepenaliseer<br />
word.<br />
7.2 Wat gebeur wanner ‘n dier wat deur die beoordelaar self geteel word? In<br />
hierdie geval is die prosedure duidelik: die dier moet op sy gesit word, terwyl<br />
al die ander soos gewoonlik geplaas word. Daarna word ‘n onafhanklike<br />
beoordelaar (aangestel deur die hoof vee opsigter) gevra om die dier te<br />
plaas, sonder om die volgorde van die diere wat alreeds geplaas is te<br />
verander.
