Megalac

to enhance fertility

Poor fertility is a major problem in many herds in the UK; conception rates have continued to fall

over the past decade. This has a major impact on farm profitability, with estimates suggesting a

cost to the farmer of £5 per cow per day for every day’s delay in getting the cow back in calf, this

cost is amplified further if the calving interval exceeds 420 days.

This cost of £5/cow/day open can offer a

significant financial benefit by reducing

calving interval (CI). If for example a 150 cow

farmer who currently has a CI of 420 days can

reduce this down to 410 days, £7,500 would

be added to the profit of the business.

One of the key factors determining successful

conception is the energy status of the cow.

In early lactation, dry matter (DM) intakes are

lower than required and result in a negative

energy balance. During this period cows ‘milk

off their backs’ to supply the energy required

for milk production consequently reducing

the cows body condition score (BCS). This

scenario of ‘negative energy balance’ can

result in major reductions in fertility and

emphasises the importance of monitoring the

body condition score (BCS) and optimising

DM intakes in early lactation.

Negative energy balance has a major effect

on conception rate. As demonstrated in

Figure 1, cows gaining more than 0.5 units

of BCS had a conception rate to first service

of 56%, compared to 43% for cows losing 0.5

units of BCS. With excessive condition loss,

more than 1.0 BCS unit, conception rate fell

to only 29%. Results from research studies

have consistently reported a reduction in

conception rate of up to 10% for every 0.5 unit

loss in BCS during the early lactation period.

It is often assumed that a modern Holstein cow

will lose 0.5 BCS in early lactation, but it is

important that this is measured and restricted.

This can be done by optimising DM intake

with a stress free transition stage. Increasing

the energy density of the diet can also help

minimising negative energy balance, by the

inclusion of Megalac. Megalac is a protected

fat with an ME concentration of 33.3 MJ/kg

DM. It is recommended for inclusion at up to

500g/head/day.

Preserve and protect

your forage

With the recent adverse

weather conditions many

dairy farmers are facing the

challenge of maintaining an

adequate supply of forage

throughout the winter. It is

therefore important to be

planning for the winter ahead,

by measuring the clamped

silage and assessing fodder

availability. Table 1 illustrates

how to calculate forage stocks

for the winter ahead.

With the expected forage shortage, the

process of ensiling efficiently is more

important than ever. It is critical to get

sufficient compaction and a well sealed

clamp. It is common to see mould on the

face of maize clamps particularly in the

summer months when it is taking longer to

get across the face. Wynnstay Corn additive

can assist with the challenges presented with

consolidating this high DM valuable crop.

Due to the high starch and sugar levels in

maize, it is prone to mould growth. Wynnstay

Corn’s unique two way formula includes a

mould inhibitor and a Lactobacillus bacteria.

The mould inhibitor has an immediate effect

through the action of Alliin which restricts

mould growth during fermentation. Acetic

acid is then produced by specific bacteria

and acts as a long term mould inhibitor, and

preservative.

Visqueen Clingseal

The results will be:

• A more stable clamp face with reduced

heating and consequently less waste.

• Significantly reduced risk of mycotoxins

• With good clamp management, an

additional 5-6 days to cross the clamp

• Reduced ME losses due to reduced

heating at feed out.

The Cost?

£1.30 per tonne treated.For example the cows

are eating 20kg of maize per day an added

cost of 2.6p per cow/day or £5.20 per day for

a 200 cow herd.

Visqueen Clingseal is a product becoming

increasingly popular throughout the UK.

It clings closely to the surface of the

silage,improving anaerobic conditions, and

reduces spoilage across the top and the

shoulders of silage clamps.

Every cubic metre of maize weighs 750kg

(table 2) with a DM of 30%, and a value of

£25/tonne, this equates to approximately £20

per m 3 . If you are experiencing an average of

10cm of spoilage across the top of the clamp,

it is costing £2 per m 2 . Visqueen Clingseal has

a reputation for significantly reducing waste.

As maize is often an expensive crop due to

poor yields in marginal areas, preserving

everything in the clamp is critical. With the

cost of Visqueen Clingseal at approximately

11 pence per m 2 , considerable savings could

be made by purchasing this highly effective

product from any Wynnstay Store.

ROVIMIX ® Biotin

Optimum Milk Yield and Hoof Health

Maximising milk output and feed

efficiency are top priorities for milk

producers.

It is widely accepted that high starch diets are necessary to

optimise milk production. Starch is the building block for

glucose, the most important energy source for milk production.

Biotin plays a key role in the activity of specific liver

enzymes responsible for glucose synthesis. Although biotin

is produced naturally by rumen microbes, the quantity is

insufficient to meet the requirements of the modern dairy

cow. Trials conducted at leading research centres in Europe

and the US confirm that supplementing cows with ROVIMIX®

Biotin can improve milk production.

Good locomotion is essential for

profitable, healthy cows. Even cows

with moderate symptoms of lameness

can lose 5% of production while

severely lame cows can suffer yield

depressions exceeding 30%.

Many locomotion problems are the consequence of horn

lesions which are associated with poor horn quality. Horn

grows at about 5mm per month which means that the cow’s

horn capsule is a composite of horn laid down over a 12-15

month period. Although damage can occur quickly, the repair

can be very slow. This means that prevention of problems

and damage must be a priority.

Biotin is available in

selected Wynnstay..

• Heifer rearing and

dairy feeds

• Minerals

• Boluses

Biotin is required for the synthesis of keratin and the lipids

which help cement hoof horn and so improves its structural

integrity. Field trials across Europe, Australia and the USA

confirm that supplementation with ROVIMIX® Biotin:

• Improves hoof horn quality

• Improves locomotion score

• Reduces the incidence of clinical lameness associated with

common horn lesions such as white line disease

Bigger is Better! HAUC study investigates

A study was carried out at Harper

Adams University College involving

80 Holstein and Beef X Holstein bull

calves. The study was intended to

show the difference in performance

from two treatment groups, one of

40 calves fed 3mm weaning pellets

and the other involving 40 calves

fed 6 mm weaning pellets. The

calves were individually housed and

fed Wynngold Bloom milk replacer

mixed at 125 g/litre, fed twice daily

at 2 litres per feed. On day 8 the

calves milk intake was increased to

5 litres per day and Wynnstay Start

‘n’ Wean pellets were offered, either

3mm or 6mm depending on the

treatment group. The calves were

gradually weaned at 42 days.

Johne’s Disease

Johne’s is not a new disease, it was first

characterised in 1894, but the prevalence

increases with more intensive farming

practices. Movement of animals between

farms, the development of larger dairy

units and management practices such as

indoor calving all contribute to a more rapid

spread both between and within herds. As a

consequence, the herd prevalence of Johne’s

in countries with a more developed dairy

industry has been increasing.

What causes Johne’s?

Johne’s is caused by a bacterium, Mycobacterium avium

paratuberculosis (frequently abbreviated to ‘MAP’). The bacterium is

related to Mycobacterium bovis, which causes tuberculosis in cattle.

6


How is it passed on?

The easiest time to infect a newborn calf is

during the first 6-10 hours after birth. At this

point the gut wall will allow the passage of

both protective antibodies and pathogens

such as MAP. Minimising the challenge to

the newborn calf revolves around reducing

the number of pathogens in its immediate

environment. A clean calving box with

clean bedding is essential and removing the

calf from the cow within 15 minutes is an

effective way of reducing infection from MAP.

In infected herds feeding only high quality

colostrum from ”Johnes negative” cows is

essential. Following the colostrum period it

is safer to feed a high quality milk replacer

in order to reduce the risk of MAP infection

from whole milk.

Managing the disease -

Danish Experience

The Danish Cattle Federation initiated a

programme in Denmark and carried out

research from 1998-2005 to estimate

prevalence, establish control options and

convey messages to farmers. Farmers

demanded a voluntary control programme,

and this was set up in 2006 and 40% of

Danish cows are now involved in this scheme.

Farm level components:

• 2 x 20 page manuals covering risk

assessment and herd Johne’s background

• 4 annual herd tests (all lactating cows

tested with milk ELISA)

• Risk assessment

• Herd action plan based on test results

This is a risk based management programme

which involves the identification of high,

medium and low risk animals and the

implementation of a programme to manage

each according to risk level. Effective control

requires implementation of all agreed actions.

Positive actions

Culling of the highest risk cows significantly

reduces the proportion of test-positive cows.

Removal of calves from the highest risk cows

within 2 hours results in a notable reduction

in the proportion of test positive cows

(compared with leaving calves with all cows).

Summary to Johnes disease

• Johne’s has a significant impact on yield

and fertility in the dairy herd and is seen

as a significant welfare and production

issue in the UK

• There is no proven causative link between

Johne’s and Crohn’s disease in humans.

• There is no cure for Johne’s

• Vaccination has limited value and can

interfere with the TB reactor test. Not

recommended

• MAP is found in colostrum and milk;

pasteurisation does not give 100% kill of

the organism

• Dried milk products made using pasteurised

milk will contain a lower level of MAP

than the raw milk from which they

originated. The feeding of calf milk

replacer will present a significantly lower

risk to the newborn calf than the feeding

of unpasteurised milk from a cow carrying

MAP

• Snatching calves from high & medium risk

cows within 2 hours of birth will help to

reduce the spread of Johne’s within a herd.

• There are no ‘quick fixes’ in the

management and control of Johne’s

• No single action will be effective in

controlling the disease.

• The application of risk assessment and

long term management programmes can

significantly reduce the prevalence over a

period of time (6-8 years).

Practical

Calf

Rearing

Points

The economics of calf rearing

extend further than the cost

per day or the cost per kg

of gain. The influence of calf

rearing can affect the lifetime

profitability of the animal.

Effective calf rearing can be achieved by

following the 5 C’s:

Colostrum - it’s a race between the

bacteria in the environment and the

antibodies in the colostrum – first one

there is the winner !

Calories - be prepared to increase the

amount of milk powder mixed per litre

when increased growth rates are required

or when temperatures fall.

Cleanliness - maternity pen should be

clean and dry.

Comfort - in the first week of life a calf

will lie down for 19 hours each day. Even

at 6 weeks it will spend 17 hours lying

each day so a clean, dry and insulated

bed is important.

Consistency - weigh milk powder. Using

jugs and cups to gauge the weight of

milk powder introduces variation. Keep

the water temperature the same every

time.

Minerals

for transition cows

A cow calving at grass as

nature intended – and yet this

cow is considerably more at

risk to milk fever than a cow

calving inside on straw.

To understand why this is the case, we have to

look in more detail at the causes of milk fever

and the background to why the incidence is

increasing.

Milk fever and its associated sub-clinical

symptoms of retained cleansings, extended

calving, displaced abomasums and poor milk

initiation are due to the inability of the cow

to find sufficient calcium from her skeletal

reserves and diet, to meet all her needs at

calving.

Calcium

It is the explosion in demand for calcium

within the first 24 hours of calving, highlighted

by a x 25 increase in requirement, which is

at the heart of a growing incidence of milk

fever related problems on many farms. Milk

contains a constant 1.2g calcium per litre. Not

surprisingly, as modern genetics continually

raises milk yields, the demand for calcium is

also increased. Cows also need calcium for

muscular strength and stamina, not only to

expel a calf, but also to cleanse her uterus of

placental tissue.

If a cow cannot find sufficient calcium at

calving and for the few day post-calving

when appetites may be reduced, then one or

more of these calcium dependent processes:

ease of calving, milk initiation and cleansing,

will be affected. Of course, if calcium supply

is significantly short then the cow goes down

with classical milk fever. The economic

losses associated with calcium deficiency are

huge, easily £300-£400 per cow as not only

is potential milk yield lost, but cows are also

less fertile. Ensuring an adequate calcium

supply at calving is therefore a nutritional

priority.

However, calcium supply is only half the story

because at a time when her needs at calving

are increasing, her ability to source calcium

from her skeleton and diet is decreasing. This

calcium “double-whammy” is largely due to

increasing levels of potassium in grass which

makes the cow more “alkaline”, and less

efficient in handling calcium.

In recent years potassium levels in grass

have been increasing which is probably due

to the continuing improvement in grassland

management based largely on higher

productivity rye grass mixed leys and slurry

being targeted at silage ground rather than

grazing. Since 1996, potassium levels in

grass silage have increased by around 80%

(see Graph 1). This increase should be judged

in terms of the milking cow’s requirement of

between 1.0-1.5% (Dry matter basis) in the

complete diet.

Cation-Anion Balance (CAB)

The level and balance of potassium and other

minerals which affect the acid or alkaline

nature of the cow is expressed in terms of

“Cation-Anion Balance” or CAB for short.

Cations are alkaline and include Potassium

and Sodium, while Anions are acid and

include Chloride and Sulphur. In practice,

however, it is Potassium and Chloride which

dictate where the Cation-Anion balance

resides.

CAB not only determines whether the cow’s

internal tissues are acid or alkaline (as

measured by urine pH) but also the overall

water balance, which is fairly important to a

cow yielding 40 litres. Figure 3 explains CAB

and the Ideal Range for Milking Cows (+200

to +400 m.eq/kg dry matter) and Pre-Calving

Cows (+100 to -100 m.eq/kg dry matter).

As Potassium increases CAB, high potassium

forages such as grass are clearly very suitable

for milkers. This observation is hardly a

surprise, as cows evolved on grassland.

However, for the modern, potentially high

yielding transition cow, the ideal CAB

range for releasing the calcium the cow

needs at calving is much lower and slightly

more acid. In this case, high potassium

forages such as grass are a liability as their

alkalinity suppresses calcium use rather than

encouraging it.

The fact that CABs of grass silage have been

steadily increasing (up from +239 to +441

m.eq/kg dry matter over the period 1996

to 2009 in line with potassium) is making

it more difficult to achieve the lower CAB

necessary to satisfy the transition cow.

Fortunately, most dairy farms now have

access to forages other than grass, which

generally have lower CAB values, as shown

in Table 1.

yield, and are summarised in Table 2.

For lower yielding herds, the traditional down

calver approach of improving calcium supply

at calving by keeping cows deliberately short

with the aim of making them “hungry” for

calcium has worked well over many years.

However, as milk yields have risen and as

it is increasingly difficult to keep calcium

intakes below 50g/day, so other options

have arrived on the scene. At the opposite

extreme to “down calver” is the “full CAB”

approach which uses anionic salts (chlorides

and sulphates) to acidify the cow in order

Table 2. Transition Mineral Options

Option

to stimulate calcium release from bone and

improve absorption from the diet. In this

option, high levels of calcium are fed to take

advantage of the improved efficiency of use.

This strategy works well for high yielding

herds (>10,000 litres) and the moderately

yielding herds, which for practical reasons

have to use a high proportion of grass silage

(with a high CAB) in the transition diet. For

moderate to high yielding herds (6,000-

10,000 litres) a “semi-CAB” regime is most

appropriate which combines a “halfway

house” CAB of zero to +100 combined with a

calcium intake of 70-90g/day. This approach

is more flexible than the “full CAB”, where

it is important that every cow receives its

daily allocation of anionic salts for it to work

effectively, and it is also better balanced for a

mixed forage transition diet.

Summary

Wynnstay has developed PREPARE NUTS, a

“semi-CAB” concentrate for Transition cows

which enables the target CAB range to be

achieved for diets containing mixed forages

and straw.

Heifer calves are

valuable assets and it

pays to protect them

Surely no one sets out to rear

dairy heifer calves unhealthily,

increase their rearing cost or

reduce their future milking

performance. Yet this could

be the outcome if respiratory

disease is not kept at bay.

It has been identified that

pneumonia during the first

three months of life is likely

to reduce first lactation milk

yield by 2.2% and increase age

at first calving by two weeks.

Financially, the 2.2% reduction on a 7,000

litre first lactation at 25p/litre is worth £39.

At £1.65/day, two weeks of additional rearing

time costs £23. And the cost of an average

pneumonia case has been calculated to be

£43/calf. Together, these amount to £105 per

case.

In spite of these serious consequences, the

early stage of pneumonia can be a bit like

an annoying background noise, like a milking

parlour vacuum pump or a noisy fridge

compressor for example. After a time, you

may stop noticing unless it suddenly stops.

Similarly, when you put out feed or spread

new bedding, you can get used to hearing

a few animals coughing. Most of the time

it may not sound serious, but it is the case

that familiarity can breed acceptance. As a

result, investigation may be delayed until

the respiratory infection has become more

serious, affecting more animals, and more

difficult to treat successfully.

Yet there are farms where dairy heifers rarely

get even a mild respiratory infection. Here are

the main elements employed in heifer rearing

programmes that promote strong immune

systems and minimal pneumonia incidence:

• Every new-born calf receives three litres

of good quality colostrum, ideally from its

own mother, within the first six hours from

birth.

• Calves live in a low moisture, clean air,

no-draught environment. This is made

possible by efficient drainage throughout

the inside of the building and around the

immediate external area, good ventilation,

and plentiful fresh dry bedding.

• Minimal stress arising from weaning,

disbudding, over-stocking, transport, mixing

into new groups, etc. Avoid imposing

several stress factors at the same time.

• Sound nutrition and fresh clean water

available 100% of the time.

• Vaccination against the three main viral

instigators of respiratory disease (RSV, Pi3

and IBR) and the BVD virus that causes

immunity suppression, to which 95% of

UK dairy herds have been exposed. The

Rispoval range of vaccines from Pfizer can

be tailored to meet individual farm needs.

• Good stockmanship with constant

awareness and active listening and

observation for the early signs of

respiratory infection (not just coughing,

but increased breathing rate and less

aggressive feeding than usual).

At this time, when dairy replacements are

in short supply, a herd’s next generation is

a particularly valuable asset that warrants

tender loving care, and attention to detail,

from the moment each calf is born. For

specific advice about healthy heifer rearing

on your farm, please show your vet this article

and seek their advice about changes for the

better that you could introduce.
