ACKNOWLEDGEMENT<br />
Uganda National Farmers Association (U16FA) is very grateful to DANIDA for<br />
funding the production of the Farmers Guide Series. We acknowledge the Policy<br />
and Resource Committee (PRC) of the Farmers Organisation Component of the<br />
Agricultural Sector Programme Support who approved the fimds.<br />
Ms Alice Eunice Tibazalika Agricultural Advisory Manager, Uganda National<br />
Farmers Association is highly cornended for initiating and co-ordinating the<br />
development of the books. Appreciatiodgratitude also goes to Mr. Augustine<br />
Mwendya Chief Executive Secretary, Dr. Fleming Eriksen <strong>Research</strong> and<br />
<strong>Extension</strong> Advisor and Mr. Sylvester Kamanyire Kugonza Coordinator Farmers<br />
Organisation Secretariat for their ianvahlable professional guidance and editing the<br />
books.<br />
Finally UNFA wishes to thank the farmers and extension workers for providing<br />
some of the illustrations used as well as their constructive adsice on the drafts.
One of the major functions of Uganda National Farmers Association (UNFA) is to<br />
provide agricultural advisory services to farmers. This is aimed at increasing<br />
farm productivity and production in order to ensure household food security.<br />
generation of income and eradication of poverty. Publicaticln of reading materials<br />
is one of the ways in which improved agricultural technologies can be extended to<br />
farmers.<br />
UNFA's agricultural advisory services are demand driven and based on cost<br />
recovery. They are implemented by District coordinators, agricultural advisors,<br />
extension link farmers and contact farmers. The technologies are introduced to<br />
farmers through on-farm demonstrations/trials, courses and visits to special<br />
interest groups and individual farmers. Ilowever, coverage is still limited due to<br />
inadequate resources.<br />
To re-enforce these activities, there is need to avail reading materials on specific<br />
enterprises of interest to farmers. However, even such materials tailored to their<br />
local needs are not readi!y available. This has contribute:d to the slow rate of'<br />
adoption of improved technologies, thus reducing the productiv~ty and<br />
production.<br />
There has been a growing demand by farmers ana prxvate organisations for books<br />
that can guide farmers to manage specific enterprises. To address this problem,<br />
UNFA has produced farmers' books on improved agricultural technologies with<br />
the most up-to-date recommendations in specific disciplines of agriculture. The<br />
books are aimed at giving practical guidelines to the farmer on how to manage his<br />
or her enterprise profitably. For si~sfainable production, wFA encourages all<br />
farmers to take on farming as a business.<br />
It is advisable that farmers get the relevant training first, and use these books as a<br />
reference to re-enforce learning. In addition, they are advised to constantly<br />
consult extension workers in their respective areas, as this combination will lead<br />
to successes in farming.<br />
UNFA, therefore, calls upon all farmers to utilise the information in these books<br />
2nd share it with others so as to cause a. multiplier effect in production.<br />

Rabbits are not violent and can thus be handled by all members of the<br />
family.<br />
Keeping rabbits is a nice way of utilising things like banana leaves,<br />
maize leaves, sweat potatoe vines, and others,, which would have been<br />
wasted.<br />
2.0 BREEDS OF MBBITS<br />
The most common rabbit breeds kept are:<br />
Dutch<br />
This is black or brown with a white band of fur around its body at the<br />
shoulder and a white band down the middle of its face. It is a small<br />
breed, which weighs 2.5 - 3.5 kg at maturity (see Figure 1).<br />
o Chinchilla<br />
Figure 1: Dutch breed<br />
This breed has a blue grey colour with a white belly. It has a<br />
characteristic ruff or dewlap, which is a thick fold of skin around the<br />
chest. It can weigh 3-4.5 kg when mature (see Figure 2).<br />

4.3 Materials used in the construction of rabbit houses?<br />
a There is a variety of timber that can be used as poles of the rabhit<br />
houses. It is important tl ?at the I: : treated to protc :ct them from<br />
mites. Eucalyptus poles i are stror an be u$ ;ed and the bigger the<br />
pole the longer it will last.<br />
c-.<br />
0 The timl )er used I can be any type and will strongly depend on the<br />
amount of .. mon ley available. The stronger the timber, the more<br />
...<br />
expensive ~t WIII be. The timber used should be of the following sizes:<br />
lin x 12in x 14 feet and 2in x 12'' x 14 feet<br />
The roof can be made of tins, iron sheets or wood. It is very important<br />
that the material used is able to protect rabbits from sunshine and ram<br />
The wall can be made out of concrete or wood. If wood is used, it must<br />
be the strong type which can protect the rabbits against predators and<br />
thieves.<br />
r The flool made ot<br />
(mesh) which enables<br />
. droppings to pass tnrougn easily.<br />
The hutch must have a door with latches and hinges<br />
The materials used should be those which are readily available and cheap.<br />
The hutch must be strong enough to withstand damage from hungry dogs<br />
and thieves. Common materials are eucalyptus or "musambya" for the<br />
frames and legs while "Kirundu" timber is used for the walls.<br />
Figure 8 shows the set up of the material in the construction of the hutch;
Figure 8: Showing the set up of the materials used to construct a hutch<br />
4.4 What are the common design features of an Outdoor rabbit house<br />
(hutch)?<br />
An out door hutch must have the following design features<br />
A sloping roof and three solid walls to provide protection against rain,<br />
wind, sunshine and to keep out intruders.<br />
Weld mesh on top of the door and sideu7alls to provide air circulation<br />
and observation of the rabbits by the keeper.<br />
Wooden slated or wire floors. Self-cleaning wire floors are most<br />
suitable as they will allow the feces and urine to go through.<br />
Strong floor frames must be constructed to prevent predators from<br />
attacking fiom below.<br />
A strong door with a pad-lock must be put to ensure security from<br />
thieves.<br />
Hutch legs at least I, meter high are required to deter predators such as<br />
rats, cats, dogs, snakes and there must be rat and ant traps which are of<br />
great help. The ant and rat traps are usually metalic and empty tin<br />
paints can be used for this purpose.<br />
Shutters, boards, or sacks must be available: so that they are put to<br />
protect rabbits fiom rainstorms at wired sides.
Figures 9 and 10 illustrate the design of outdoor hutches which are used<br />
by many rabbit farmers in Uganda<br />
Figure 9: Showing the dimensions and desip of an outdoor hutch which<br />
can accommodate one full grown Doe and its young ones<br />
Figure 20: Photograph of an outdoor rabbit hutch<br />
4.5 Location and siting sf outdoor hutches<br />
As earlier stated the hutches are most commonly constructed near<br />
homesteads. Hutches can be placed on verandahs of houses and against<br />
fences as this will give shade and protection from sunlight, rain and wind.<br />
SuEcient sunlight must be ensured to provide both Vitamin D synthesis
and ultra-violet rays for reducing infection in the hutch. However the<br />
hutch should not be exposed to so much sun heat, because heat stress is<br />
one of the conditions that cause mortality in rabbits. Therefore rabbits<br />
must be in a place which protects them from the mid afte :moon heat.<br />
- .J - . Place the outdoor hutches next to the house in oraer . ro provide enough<br />
security against thieves and predators.<br />
'3utches must be constructed such that there is no excessive noise and<br />
make which may seriously affect confort of the rabbits. Rabbits need a<br />
luiet environment during feeding and farmers must locate the hutch in a<br />
place that limits disturbance. Rabbits must be placed as far as possible<br />
fiom the Kitchen to avoid smoke and heat stress.<br />
4.6 Indoor Hutches<br />
In commercial rabbit production on a large scale, it is advisable that the<br />
farmer puts hutches indoors. This is done by construction of a large<br />
building with suficient ventilation and security provisions.<br />
Hutches within the house can be simple and can be made as boxes<br />
suspended from the roof, Sometimes hutches are constructed on the floor<br />
in a house. When the hutches are constructed on the floor, the rabbits can<br />
be kept on concrete floor, which can be kept dry, or they can be kept on<br />
marram floor where they can be allowed to burrow in the underground.<br />
Rabbits can rear their young ones in the bumw. Bucks should be kept<br />
separate fiom does and young ones to prevent unnecessary mating and<br />
eating of the young ones.<br />
Cleanliness must be observed strictly and over-crowding must be avoided.<br />
4.7 Outlay and equipments needed in a rabbit house<br />
The equipment in a rabbit house include the water trough, feed trough,<br />
roughage rack and kindling box. A piece of wood can be placed in the<br />
hutch for chewing because rabbits like to gnaw and chew and can easily<br />
eat their way out of the hutch. This habbit is increased if the rabbits are not<br />
fed properly.<br />
e Water troughs<br />
These can easily be made from a tin and a bottle. The Waterers should<br />
be fixed to the hutch wall or floor to prevent tipping over. Regular
cleaning is a must as the rabbits tend to foul the containers. Figure 11<br />
(a) and (b) shows how the water troughs can be fixed to the wall.<br />
* Feeders<br />
Figure 11: Showing how to fix home made Wat6:rers in a hutch<br />
Adopted fiom Tropical Agriculturist<br />
All hutches must have feed troughs in them which are used for feeding<br />
of concentrated feeds. Concentrated food is very expensive and if used<br />
must not be wasted. Feeders must be fixed on the wall or floor and<br />
should have good depth. Heavy clay containers can be used as they<br />
will not tip over easily (see Figures 12 (a), (b) and (c).<br />

(c) Clay homemade feed trough<br />
Figure 12 a,b,c: Showing the different types of feed troughs:<br />

e Kindling boxes:<br />
These boxes are very important during kindling because they keep the<br />
young ones warm and they prevent them from wondering around the<br />
hutch. Kindling boxes also confine does to enable the young one<br />
suckle in addition to providing a danger free environment to the doe<br />
and it .s young ones.<br />

Kindllng ooxes are made from wood of the types mentioned in the<br />
section for materials used in the construction of hutches and can have<br />
different designs and dimensions as given .in figure 13 (a), (b) and (c).<br />
Figure 13: Sarnwmg uyr;lr nrzu csvavu luururnng ,~r)xes<br />
4.8 Maintenance sf hutches and equipment<br />
Maintenance of hutch.es is very necessary and must be a daily practice.<br />
After construction of the hutches, they must be cleaned and disinfected<br />
Thereafter they are lefi for 1-2 weeks before introducing the rabbits.<br />
Maintenance of the hutches will then become a daily activity. Farmers<br />
must adopt a routine and a working schedule for purposes of maintenance<br />
of hutches and equipment.
1 Every farmer must decide on the routine to be followed depending on the<br />
level of management helshe intends to achieve.<br />
, I<br />
i However the following routine is suggested and can be adopted by the<br />
farmers<br />
Cleaning of the hutch QW C~UI~II~GIIL ar least every 2-3 days.<br />
Complete cleaning and disinfection between litters using soap and<br />
plenty of water. After washing and disinfection, ensure complete<br />
drying especially by allowing the hutches to dry using direct sunlight.<br />
0 Checking and repairing of all loose boards, tins, wires which may<br />
allow rabbits to escape or predators to enter<br />
0 Checking and prevention of sharp edges which may injure the rabbits<br />
5.0 ACQUIRING AND HANDLING OF RABBITS<br />
5.1 Acquiring of rabbit stock<br />
When acquiring rabbit stock buy from highly productive commercial<br />
sources and farmers should take the following steps<br />
Purchase stock from farms that have been certified to be disease free<br />
by veterinary personnel. Ensure that the veterinary personnel has<br />
conducted a culture and sensitivity test for pasteurellosis as this<br />
organism causes diseases of great economic importance in rabbit<br />
production.<br />
Rabbits should preferably be purchased when they are 3-4 months of<br />
age. After purchasing the rabbits, treat them against coccidiosis before<br />
they are put in the hutches.<br />
Place newly acquired rabbits and those from shows or borrowed bucks<br />
in quarantine for at least three weeks to detennine whether they were<br />
incubating any disease or not. In this way rabbits, which had diseases<br />
in the incubation stage, will be detected and treated before they are<br />
introduced to the rabbit flock.<br />
ARer the introduction of the rabbits in the hutches, they have to be<br />
~bservcd on a daily basis and sometimes it is necerssary to handle them for<br />
examination or reproductive purposes.<br />
5.2 Handling of rabbits<br />
Rabbit management demands that the farmer be well versed with rabbi!<br />
handling techniques. Once in a while the farmer will handle rabbits for<br />
purposes of
Taking rabbit weight for record purposes<br />
Checking rabbits which are expressing signs of ill health<br />
Mating especially when transferring the doe from its hutch to the buck<br />
hutch<br />
Assisting the doe during the mating process<br />
Pregnancy testing<br />
Sexing of young ones<br />
e Marketing<br />
Handling of rabbits c is very important to avoid hurting the<br />
animals and causing tll~lll atless. First and foremost, rabbits are very<br />
peaceful animals and will not hurt the handler unless in pain, where<br />
rabbits have a tendency to scratch. However, some rabbits can -be<br />
aggressive, granting and even biting. Handling should be purposehi and<br />
firm. A small piece of wood can be used to trap the rabbit in a corner to<br />
avoid chasing it around the hutch or cage.<br />
The handling methods t hat can 1 be used include the following:<br />
5.2.1 Holding the rabbit by the ears<br />
This method of handling will cause the rabbit 1:o keep calm in the same<br />
place (see Figure 14)<br />
Figure 14: Showing quieting a rabbit by holding its ears<br />
Caution: Rabbits should never be lifted by their ears because it is very<br />
painful to them. It may also cause stretching of the ears or their base<br />
which may result in the ears beginning to drop.
5.2.2 Handling rabbits by the scruff<br />
In this method, the rabbit is I the skin behind the ears-the scruff It<br />
is important to get a quick g! mce. The other hand can then support<br />
the rabbit under the hindquarters (see Figure 15)<br />
Figre 15: Handling a rabbit by its scruff.<br />
Caution: The handler should avoid long nails.<br />
5.2.3 Handling rabbits by the pelvis<br />
This method is used for young rabbits only. It is .used mainly when young<br />
rabbits me being transferred from the hutch to the basket or box by<br />
handling them by the pelvis or the skin on their back (see Figure 16).<br />
Figure 16: Handling x rabbit by the pelvis
5.2.4 Transporting rabbits<br />
All rabbits brought in or taken out of the farm need to be transported in an<br />
appropriate way, which will ensure their safety. This can be done using<br />
cardboard boxes, or woven baskets. The box or basket must be well<br />
ventilated, but firmly covered to prevent the rabbit from jumping out (see<br />
Figure 17).<br />
Figure 17: Showing a box used to transport rabbits<br />
Afier stocking the rabbits, they n xys be fed on a balanced diet.<br />
. . . ,.<br />
6.0 FEEDS AND FEEBIN(<br />
Rabbits must be fed adequately because tois will determine their<br />
productivity and health status.<br />
6.1 Important aspects to note abou t feeds r and feeding of rabbits?<br />
. .<br />
Feeding is an important activltv tn rabbit kee~inn combined with good<br />
health maintenance.<br />
Rabbits kept in hutch .es are tc<br />
: on the<br />
.<br />
keeper for supply<br />
.. ..<br />
of feeds unlike in case or wlid rabLILa, vvutch ptck and chose their<br />
feeds.<br />
Rabbit farmers should provide good balanced diet for the rabbits.<br />
Rabbits carry a very big advantage in that they can feed on most of the<br />
common grasses and weeds found in gardens and can also feed on<br />
many crop by-products, which could otherwise be thrown away .<br />
* Rabbits are voracious feeders and each could eat more than half its<br />
weight in a day and suficient food both in quantity and quality must<br />
be available everyday<br />
B All foods contain virtually all the needed nutrients but sometimes these<br />
nutrients are at such levels as to be of little value to the rabbit. This is<br />
the reason for concentrate feeding as it is the only sure way of<br />
balancing the diet of the rabbit.
6.2 How do you feed rabbits?<br />
There are three possible feeding systems and the choice of each will<br />
depend on the capability of the rabbit farmer and the market conditions of<br />
the rabbits.<br />
0 Extensive system of feeding<br />
This is total dependency on forage and kitchen wastes. The advantages<br />
of this system of feeding are that of being cheap and the ease of<br />
supplying the quantity of food required. The disadvantages are that<br />
supplies of forage vary in the different seasons of the year and<br />
therefore the quality of feed is not assured and is usually poor. It also<br />
requires alot of labour and there are greater chances of having disease<br />
and health problems.<br />
Intensive system of feeding<br />
This involves total dependency on prepared concentrates fiom the feed<br />
meal or commercial feeds. The advantages of this system are that there<br />
is little risk of disease transfer and a high level of production can be<br />
achieved. Also the nutritional requirements of the rabbit can be met<br />
with certainty. However the disadvantages of this method are very<br />
costly and depends on the supply of commercial feeds, which may not<br />
be readily available.<br />
Semi-intensive system of feeding<br />
This' system falls between extensive in terms of advantages and<br />
disadvantages. It is also the most suitable system for small scale rabbit<br />
keepers as it makes use of the forages which are normally available<br />
and concentrates which can be made at home at critical times such as<br />
pregnancy, lactation and post rearing.<br />
6.3 What are the types of feeds available for rabbits?<br />
6.3.1 Forage sources<br />
Usually rabbits can be fed on most of the grass,es and weeds commonly<br />
found in the gardens and fields. The palatable grasses and weeds, which<br />
can be used as feeds for ra.bbits, are given in table 1

Group A and B include protein-rich foods and group C and D include<br />
energy rich foods. The following protocol can be used when mixing the<br />
feeds given in table 2.<br />
Mix 4 kg of C with 1 kg of A or<br />
Mix 3 kg of C with 2 kg of B or<br />
Mix 2 kg of D with 2 kg of I3 and 1 kg of A<br />
A farmer who does not have a weighing scale can use containers like tins<br />
or mags and measure the items for mixing in the proportions indicated<br />
when using a weighing scale.<br />
Precaution: Make sure the diff erent fec zds are r nixed w ell and pound them<br />
if necessary to break down any big pieces. Each kll-grown rabbit shouid<br />
be given about 100 gm per day with lactating and pregnant ones getting a<br />
little more. This is of course in addition to the already mentioned forage<br />
feeds.<br />
6.4 When do you give rabbits Feed<br />
The feeding of rabbits should be done preferably in the morning and<br />
evening hours when the environmental temperatures are low. This is<br />
because rabbits are naturally more active in the coolest times of the day in<br />
order to avoid heat stress.<br />
6.5 Are all plants safe as rabbit feeds?<br />
There are a number of plants, which must not be fed to rabbits as they are<br />
harmful to them. These plants include irish potatoes and their leaves,<br />
tomatoes and their leaves, egg plants, sweet pepper, Solanum gilo (ntula)<br />
etc. Also feeds like cotton seed cake should not be fed alone in big<br />
quantity as they contain a chemical called gossypol which can poison the<br />
rabbits.
While carrying out proper feeding, fmers must constantly remember the reasons<br />
which led them to starting a rabbit production enterprise. Most farmers involve<br />
themselves in rabbit production in order to generate income or have readily<br />
available animal protein for the family. Either of these will require that the stock<br />
is well fed for purposes of attaining fast growth rate and reproduction. Increase in<br />
rabbit numbers fiom the existing stock demands the farmer or keeper to have<br />
some knowledge about the reproductive behavior of rabbits.<br />
7.0 WEPRODUCTION AND FERTILITY OF RABBITS<br />
7.1 What are the characteri! a good t ; rabbit?<br />
Rabbits have high growth rate attaining maturity at 5 months for<br />
females (does) and 6-7 months for males (bucks). At this age they<br />
muse start breeding and therefore the rabbits must be fed better to<br />
realize suitable size for mating and reproducing<br />
Goo d breeding rabbits will always have a litter size of 7-9, though the<br />
first litter is smaller.<br />
The mean litter weight is usually 42-50 grams<br />
Any deviation from these paramet ers is considered as a form of infertility<br />
7.2 Emportant aspects of rabbit breeding and reproduction<br />
There are several aspects that a farmer or rabbit keeper must understand<br />
about rabbit breeding and reproduction. These aspects will make a famer<br />
or rabbit keeper detect any abnormalities when they arise. These aspects<br />
include:<br />
The gestation period of rabbits is 30days. After mating the rabbit gets<br />
its young ones within 30 days and therefore the farmer must make<br />
arrangements to manage the young one as soon as the doe is confirmed<br />
pregnant as 30 days is not much time.<br />
. .<br />
e Does are read<br />
patum) - .<br />
A well managed reproduction program for a c<br />
producing 40 to 50 weaned rabbits per year.<br />
mated within : 3-4 wee rks after delivery (gost-<br />
result in the doe<br />
If a doe comes on heat and it is not mated, it will show the<br />
phenomenon of pseudopregnancy lasting 15 .to 17 days following lack<br />
of fertilization of the liberated ova. During these days the doe wili<br />
behave as if it is pregnant and yet it is not.
e Bucks are territorial. Rabbits live in territories whose size depends on<br />
the conditions of food supply. Bucks mark their territories, fellows and<br />
offsprings by the aid of a gland secretion, found in hair follicles under<br />
the chin. Males can also mark their territories by using urine. Because<br />
of this territorial behavior, males take long to adjust when put in a<br />
doe's cage. Therefore for immediate or quick mating, the doe must<br />
always be put in the buck's cage and not vice versa<br />
Noise, smell or any unfamiliar surroundings easily upset rabbits and<br />
will affect the reproductive bahavior of the rabbits.<br />
Rabbits are social animals that live in colonies in which femzles<br />
outnumber males. However does (females) can attack off-springs of<br />
others which can lead to infant mortalities. This is why it is preferable<br />
that each doe be kept in a separate hutch.<br />
When young males reach puberty, adult males try to eliminate them as<br />
rivals by castrating them. Therefore, the young males must not be kept<br />
together with the buck.<br />
7.3 Signs of heat (estrus) in rabbits<br />
One of the routine activities that farmers must engage in is the detection :)f<br />
heat in rabbits. Heat (estrus) in rabbits is manifested by:<br />
Restlessness,<br />
e Swelling and hyperhernia I of exte: ma1 gen italia an1<br />
9 The doe tries to jump intc 3 the nei bouring cage:<br />
The estrus cycle in rabbits lasts 15-16 days and the rabbit should be served<br />
as soon as she is noticed on heat.<br />
7.4 Production cycle<br />
The period from the time .the sex of the rabbit is determined until i-ts<br />
offsprings are weaned is the production cycle. Under semi-intensive<br />
systems this must not exceed 8 months and it is usually 7-8 months.<br />
Therefore the production cycle will have so maay activities to be carried<br />
out by the fmer or rabbit keeper.<br />
7.4.1 Sexing and early growth<br />
Sexing of rabbits can be carried out shortly aRer weaning at 6-8 weeks. It<br />
is very irnpctrtant that it is carried out at this time as 6-8 weeks is the time<br />
when the males and females should be separa.ted and put in separate<br />
hutches. Sexing is carried out using the hand and the sense of vision.
For sexing, holc hit on a rlat surface, then gently push back the skin<br />
around the genital opening using a finger and thumb. In the male this will<br />
reveal the penis as a rounded tube-like structure. In the female the vulva<br />
will be exposed as an oval opening slit to the reproductive tract as shown<br />
in the Figure 18 and 19. At a later stage the male genitalia will be easy to<br />
notice as the testicles will have started to descend into the scrotum.<br />

7.4.2 Selection of Rabbits for 'breeding<br />
This is best done when rabbits reach 4-5 months. Rabbit selection is<br />
important as some of the .young rabbits must be retained as replacement<br />
stock by the farmer. While doing the selection, the following factors<br />
should be observed:<br />
Among rabbits of the same age, select the heaviest and healthiest. This<br />
is done because such rabbits are thought to have the potential of<br />
producing offsprings which will perform well.<br />
Select from the largest litter size. Selecting a rabbit on this strength<br />
relies on the fact'tha? it is capable of performing as its mother doe.
7.4.3 Mating<br />
Choose the most health looking and most vigorous<br />
. .<br />
Males chosen should have all t ~s in their scrotum a.t<br />
around 12 week!<br />
There are several C;u~~~~ur;iar~vl~> ..A mating is concerned in the<br />
production cycle of rabbits. Some of these considerations are:<br />
0 Bucks should be older at mating than females i.e. female rabbits can be<br />
mated at 4-6 months while bucks must start mating 5-6 months.<br />
The ratio of does to bucks should not exceed 10 to I (I male for every<br />
10 does).<br />
Mating should be done in the morning or evening to avoid hot<br />
weat her.<br />
Take the doe to the bucl
Q Hold the doe (female rabbit) by the neck with one hand<br />
Put the other hand under the female with one finger on each side of the<br />
tail and push gently backwards.<br />
e This will make the female lift her tail so that the male can mount her.<br />

7.4.4 Haw can ia farmer know that a rabbit is pregnant?<br />
Detection of pregnancy is very important and this is done usually 14 days<br />
after mating. Detection of pregnancy is usually and easily done by<br />
palpation, which is a skill that needs to be developed through constant<br />
practice. The technique is carried out as follows:<br />
Q The doe should be relaxed in a sitting position. The farmer should pass the<br />
fingers gently along the abdomen, between the back legs. If the doe is<br />
pregnant, the developing fetuses are felt as small beadlike lumps.<br />
s To develop the skill of pregnancy detection, farmers may start with<br />
palpation of does at 20 days after mating as the fetuses in these are easily<br />
identified. This will help the farmer develop the skill of pregnancy testing<br />
until that time when helshe gains enough skill to be able to detect<br />
pregnancies of 14.<br />
Figure 22: Showing pregnancy testing by palpation<br />
I
What other features serve as supporting evidence of pregnancy?<br />
In addition to palpa ltion of the fetu ses, farmers rrlust use other factors to<br />
confirm with certai: nty that the doc : is pregnant. The factors that can be<br />
used include:<br />
Refusal of the doe to accept the buck if taken to the hutch of the buck.<br />
However, it is important to note that in some instances pregnant does<br />
can often accept bucks.<br />
e By around 28 days, the mammary gland!; will have developed<br />
significantly and this can be regarded as final confirmation of<br />
pregnancy.<br />
At 29 days, the doe will begin to remove fir fiom her abdomen to<br />
make a nest for the young ones.<br />
7.4.5 Pregnancy:<br />
Pregnancy lasts for 30-32 days and therefore does should be well fed and<br />
conforted. Heat stress and noise should.be avoided to avoid disturbance of<br />
the pregnancy. Five days to kindling, the hutch must be cleaned and a<br />
kindling nest provided. The kindling box should be provided with dry<br />
grass or a suitable soft bedding to enable newly born babies keep warm<br />
and avoid losses due to chilling.<br />
At 29 days, the doe plucks off her fbr and makes a nest. In addition to the<br />
rabbit providing the f3r to protect the young ones against cold, the<br />
shedding of the fbr will help to expose the teats in preparation for<br />
suckling.<br />
Plenty of water must be provided to avoid dehydration. This is because<br />
dehydration can lead to the doe eating one or more of her young at birth or<br />
thereafter.<br />
7.4.6 What happens if a doe has a false pregnancy<br />
The cause of this is mounting of a doe by a doe or the simple presence of a<br />
buck in the hutch of a doe. No fertilization takes place but this situation<br />
will trigger hormonal changes usually associated with pregnancy. False<br />
pregnancies usually last 17-1 9days after which the doe will pluck her hrs<br />
just like in the normal pregnancy. Some does have this as a habit and<br />
farmers must make sure that such does and culled.<br />
This is the act of the doe giving birth. Kindling ust~ally<br />
occurs at night anti<br />
once the process is over, the doe will pluck more fbr to keep her young
warm. Cotton wool could be added to supplement fUr if necessary. The<br />
keeper must keep on checking in cbe some of the youn er off and<br />
miss suckling, which will result into death.<br />
The doe will suckle her young once or twice a day.<br />
7.4.7 Fostering<br />
This means gettint 3 a doc e to acci ept rabbits from another doe and have it<br />
- ..- -<br />
suckle them. This may be nec ;essary where one doe does not have<br />
uficient milk. Fostering is carric :d out as follows:<br />
Mate does on the same day<br />
Litters should be born not mo re than : 3-4 days apart if fostering is to be<br />
possible<br />
Only foster rabbits, which are 5 days old<br />
Remove both the foster and donor doe from their hutches<br />
Carefilly remove the rabbits to be fostered without touching them<br />
directly. Do not disturb those not fostered.<br />
Rub a cloth in dump litter of the foster doe's hutch and wipe each<br />
rabbit to be fostered with the cloth<br />
Introduce the rabbits to be fostered, without disturbing the foster nest.<br />
Leave the newly introduced rabbits for a few hours so that they take on<br />
the smell of the hutch evenly.<br />
Return the foster doe into the hutch ar y her with good food.<br />
7.4.8 Kindling to weaning<br />
The young rabbits must be allowed to suckle colostrum, which is the<br />
concentrated first milk from the doe. Colostrum will enable young rabbits<br />
withstand health problems. Young rabbits should be leR to suckle for at<br />
least 30 days but most preferably 40 days.<br />
7.8.9 Artificial feeding of rabbits<br />
This is possible after 1-2 weeks and is done by us ing a sy: ringe. Cows milk<br />
mixed .with egg york can be used as milk substil Lute. A : little of this milk<br />
can be dropped into the rabbit's mouth. Great care must of course be taken<br />
to avoid milk getting into the young rabbit's lungs, which could cause<br />
pneumonia.<br />
The first two weeks after kindling are critical and therefore good food<br />
must be provided to the doe to ensure sufficient supply of milk. Plenty of<br />
water must also be made available. Concentrate foods must be given at.<br />
this time.
Weaning or separating young rabbits from the doe: This is usually done 6-8<br />
weeks after kindling. Young rabbits should be given rich foods i.e. concentrates<br />
after weaning with plenty of water to avoid loss of condition and after weaning<br />
the doe should be allowed time to recover her conditio~n before mating again<br />
Does can continue breeding until they are 3 4 years old.<br />
8.0 RABBIT DISEASES, THEIR PREVENTION AND CONTROL<br />
Rabbits must be in s :alth in order to bene:fit from the enterprise<br />
Diseases can result in mra~ued growth and even loss of rabbits. There is<br />
high mortality in rabbits between day 1 and two months of age. Therefore<br />
farmers must routinely observe the rabbits for any signs of ill health<br />
accordingly. It is invariably essential that the farmer knows the<br />
characteristics of a healthy rabbit and the signs that are indicative of<br />
disease.<br />
8.1 What are the characteristics<br />
Eats and drinks normally<br />

IS self grooming<br />
a The fkr is shiny, smooth and clean especially on the front paws and<br />
around the anus<br />
e Has clear bright eyes without any discharges<br />
e Normal temperature of 37-39°C<br />
Normal silent breathing, with breathing of about 40-45 breaths per<br />
minute<br />
o Shows no soft feces on the hutch floor<br />

Maintenance of normal body weight in adults<br />
8.2 How do you tell that a rabbit has ill heath?<br />
Dullness<br />
Change in appearance and habits<br />
Loss of appetite<br />
A dry, dull, harsh, starin{ chy coat indicates that something is<br />
wrong<br />

@ Loss of weight which makes the rabbit feel 'bony'<br />
Unfortunately, few of the diseases of rabbits are accompanied ' by<br />
characteristic clinical signs to allow the farmer recognize them easily.<br />
Therefore farmers should notify a veterinarian immediately they notice<br />
some of the general signs of ill health listed above. The clinical signs and<br />
treatment/control of the common diseases and disease conditions that<br />
cause losses in rabbit production are given in the appendix (see appendix)<br />
8.3 Guidelines of disease prevention/cont<br />
In general for disease prevention and control, farmers must always<br />
manage and take care of housing and ventilation, proper manure disposal,<br />
control of rodents, taking care of the birds that might enter the house and<br />
washing and disinfection of the hutches. Each of these involves many<br />
activities and it is important that the farmer or rabbit keeper develops a<br />
routine of how to attend to each of them.<br />
@ Providing good housing/hutches and ventilation<br />
The way the househutch is constructed should facilitate proper<br />
cleaning, disinfection and maintenance of sanitary conditions<br />
e.g. suitable floors, adequate waste disposal and absorbent<br />
bedding. Good ventilation must be provided as this will allow<br />
movement of air ahrough the building with the objective of<br />
replacing foul air with fresh air containing needed oxygen.<br />
e Thorough cleaning and disinfecting<br />
The hutches must aewavs be cleaned and disinfected. If there<br />
was death of rabbi1 to disease in some hutches, it is<br />
recommended that tf washed, disinfected and Iefi unused<br />
for a minimum of 2 weelts. When bringing in new stock, the<br />
cleaned hutches must be left unused for one month.<br />
Proper manure disposal<br />
I<br />
Disease causing agents may be contained in urine, feces,<br />
exhalation and in the nose and mouth discharges. These<br />
excretions may act as media for gl-owth of disease causing
agents. Therefore excrement should be removed frequently<br />
from the immediate surroundings and manure should be stored<br />
so that the heat generated kills the parasites and microbes. It is<br />
recommended that manure be kept in a covered concrete pit as<br />
this will remove it fiom the surface and will cause generation<br />
of heat that will kill the infectious agents. Spray manure pit<br />
with insecticide to inhibit development of flies.<br />
e Provide suitable feed and water con~;ainers<br />
Avoid feeding off the ground as the rabbits may contaminate<br />
the feed with their excrements. Also there will be a lot of feed<br />
wastage causing diseases related to malnutrition. Water shouid<br />
not wet the floor as this may give a good enviroment for the<br />
growth of disease causing organisms. Coccidiosis is one of the<br />
conditions that can be controlled by keeping the hutch dry.<br />
Control iand destroy rodents and birds<br />
These may spread disease and parasites. Birds may move from<br />
one rabbit enterprise to another look.ing for food and in this<br />
way, spread disease between different farms. The rats may also<br />
spread diseases from one hutch to the other and will in addition<br />
damage feeds and buildings thus reducing profits.<br />
Isolate new rabbits<br />
When introducing new animals, secure a health certificate,<br />
isolate them for a minimum of 3 weeks and thoroughly clean<br />
and disinfect the isolation stall after each animal is removed<br />
1d before animals are introduced<br />
o Proper disposal of dead rabbits<br />
Dead rabbits can be a source of infection. On death of a rabbit,<br />
call a vet erinnriai n to carry out examination and ascertain the<br />
cause of d leath.<br />
*<br />
Thereafter, ~urning of the carcasses can eliminate the<br />
~ssibilitj r of con .tamination of the surrounding. Burial of the<br />
~rcass is another - disposal technique. If this method is used,<br />
-A I---.<br />
uury deep, ai least 4 feet fiom the soil surface.<br />
e Use disinfectants<br />
This is done to create conditions unfavourable for survival of<br />
microbes. Proper cleaning will remove most microbes but in
case of a disease outbreak, the buildings must be disinfected.<br />
Foot disinfection for visitors visiting irnits is desired and this is<br />
achieved by putting a footbath at the entrance of the house.<br />
Always use a veterinarian<br />
Effective health control programs in rabbits calls fbr<br />
cooperation between the farmer and veterinarians.<br />
9.0 RECORDS AND RECORD KEEPING<br />
9.6 Why is records keeping important<br />
Record keeping is important because records:<br />
Provide an early warning of developing problems<br />
0 Provide clues to basic weaknesses in your management program<br />
e Provide information for budgeting purposes<br />
Are used to monitor health of the rabbits<br />
Are used to identi5 major costs<br />
Permit a comparison with other producers<br />
o Provide a basis for seasonal adjustments in management<br />
Records must be as simple as possible to facilitate understanding by the users<br />
of the records. They must be ke~t where they are easily accessible and in a<br />
way which minimizes trans6 one record sheet to another<br />
9.2 Types of records<br />
Records are broadly a :d into individual general arid<br />
financial Records<br />
0 Individual records<br />
These include: Animal number, age, breeding date, health status,<br />
date of birth, weight at birth, growth rate and weight at weaning.<br />
These records are used in culling of non-productive animals and<br />
selecting potential breedei<br />
e General records<br />
In these records the ~g information is kept: Feed<br />
consumption by different classes of rabbits, new purchases. death<br />
losses per period, numbel : of rabl: ,its bred, kindling and number of<br />
times bred.
9.3 Records that must be kept by the rabbit farmers<br />
Breeding recurt<br />
Expected date of kindling and exact pa.rentage of offspring<br />
Heat and services must be recorded<br />
0 Dam's offspring record<br />
Pedigree data which gives the merits of parents of each<br />
offspring<br />
Feed and live weight record<br />
This will enable estimation of feed eficiency, gain in weight<br />
and therefore the cost to produce a kg gain in weight.<br />
Other records kept include: mortality records where a31<br />
animals that die are recorded, health records where it is<br />
advisable to use health cards which show the treatments and<br />
disease treated which should be filled in by the veterinarian at<br />
the time of examinatiodtreatment<br />
Financii<br />
These records must be designed such that they take care of feed<br />
costs, rabbit purchases and sales, health and treatment costs,<br />
labour costs, depreciation of equipment and buildings plias<br />
charges for electricity, taxation, &el and transport costs for<br />
feeds, animals etc.<br />
10. MARKETING OF RABBITS<br />
Marketing of rabbits is a very important component in rabbit farming<br />
Rabbits can be marketed in the follo.<br />
e Selling to prospective farmers<br />
w Selling to supermarkets and hotels<br />
e Selling to individual consumers<br />
Each of these avenues of marketing require some special characteristics.<br />
10.11 Selling to prospective farmers<br />
Farmers who target this market should make sure that they keep rabbits<br />
that have the desired characteristics. The breed must be a good performer<br />
in terms of feed conversion and reproduction. Most prospective rabbit
farmers buy offsprings from rabbits, which are big in size and give birth to<br />
many young ones.<br />
In targeting this market, the management must be excellent and admirable<br />
by many people who visit the rabbit farm.<br />
in .r Selling to supermarkets and hotells<br />
Hotels and supermarkets need a constant supply. Rabbit farmers therefcre,<br />
need to work as grc )ups in order 1 to maintain a constant supply to<br />
supermarkets and hotel Is.<br />
-----..A<br />
Associations may be a lrcbcsaai y ~~l~~ponent in the marketing of rabbits to<br />
big organizations. Visits to the supermarkets and hotels are necessary ir,<br />
order to assure these organizations that there will be a constant supply for<br />
a given period of time.<br />
vidual consumers<br />
This<br />
--<br />
re<br />
-<br />
:quires that the rabbits are sold at a price, which is attractive and<br />
afrordable,, by the individual consumers. It is very important to sensitize<br />
the individual consumers about rabbits as an available source of animal<br />
protein. This can turn out to be the best way to market rabbits as the rabbir<br />
industrv in the country grows.
