YOUR CALF SCOUR

KNOW-HOW COULD

WIN YOU A CRUSH

This is it. The third week of

the Rotavec-Corona

competition. Read on for

details – you could win one

of the finest cattle crushes

on the market

THIS is the third (and last) competition page for the FARMERS WEEKLY/Schering-Plough Rotavec-Corona competition. Just read the text, answer the question and fill in the coupon. Theres a chance to win one of five Ritchie cattle crushes worth £1465 each.

Vital importance of colostrum

Calves are most at risk in the first two weeks of life and need a source of continuous protection against rotavirus, coronavirus and E coli. The cells lining the gut wall are shed every four days – new cells are not protected and hence are prone to attack.

In the case of suckled calves, they can get this protection by taking in milk from mothers who have been vaccinated with Rotavec Corona.

Dairy calves can be similarly protected by feeding them stored colostrum from vaccinated mothers during the first two weeks.

Two week benefits

It used to be thought that the benefits of feeding colostrum diminished markedly after 24 hours. However the latest research shows that there is a significant benefit to be gained from giving the calf more prolonged exposure to colostrum from vaccinated cows over a period of two weeks.

As well as being absorbed into the bloodstream in the first 24 hours of life, antibodies will also coat the surface of the gut villi. This creates a barrier which prevents disease organisms sticking to the intestinal wall.

Cost benefits

On top of the calf-health benefit, there are financial advantages to prolonged feeding with colostrum from vaccinated cows.

With Rotavec-Corona typically costing £8-£8.50/cow, the scour protection and feeding cost are only 71p/calf/day at most. Thats a similar cost to feeding 7kg calf milk replacer over 14 days, without the added benefit of protection against scour.

Now fill in the coupon and send it to the address provided.

YOUR CALF SCOUR

KNOW-HOW COULD

WIN YOU A CRUSH

Welcome to the second week of

the farmers weekly/Schering-

Plough competition to win one of

5 Ritchie cattle crushes worth

£1465 each. Just read the text,

answer the question published

on this page and then look out

for the competition coupon

in the Aug 24 issue of FW

The causes of scour

Rotavirus is the most common cause of scour in calves and can affect up to 90-100% of cattle. Coronavirus is less common, but its effects can be more severe than those caused by Rotavirus.

Both these are viruses, but a third agent – E Coli – is also a common cause of mortality in calves less than four days old.

Gut damage

&#8226 Rotavirus and coronavirus attack the villi lining the gut, leading to reduced absorption of water and nutrients. The classic signs are yellow/green scour.

&#8226 E Coli attaches to the cells lining the villi. They produce poisonous enterotoxins which result in increased water and electrolyte secretion into the bowel, leading to watery scour in the first two days of life.

Importance of vaccination

&#8226 Once the gut lining is destroyed by scours, it never recovers.

&#8226 Viral scours cannot be treated with antibiotics. They must be prevented.

&#8226 The only effective protection from scours is by vaccination. Vaccination produces high levels of antibodies in the colostrum, which act as a protective barrier to infection.

Involve your vet

Your vet can help in assessing whether the disease is present in your herd by supplying you with a free Schering-Plough Scourwatch testing kit. This allows you to find out if your herd is infected with any of the main causes of scour.

Samples are taken within 24 hours of seeing the first signs of scouring and before the animals are treated with antibiotics. Samples are labelled and taken to your vet, who will send them to be tested and pass on the results quickly to you.

QUESTION 2

What is the biggest

cause of scouring in calves in the UK?

A: Rotavirus?

B: Coronavirus?

C: E coli?

Please keep a note of the answer and use it to fill in the coupon that will appear on the competition page in the Aug 24 issue of FW.

YOUR CALF SCOUR

KNOW-HOW COULD

WIN YOU A CRUSH

There is a chance to win one

of five Ritchie cattle crushes

worth £1465 each in our joint

late-summer competition with

Schering-Plough. Just answer

the question on scour each

week, keep the answer in a

safe place and look out for

the coupon in the Aug 24

issue of farmers weekly

SCOUR is a common and expensive disease of calves in the UK. It is found on most farms and an outbreak can kill up to a third of affected calves.

How expensive is it?

The cost in terms of lost calves, though serious, is only a small proportion of the total costs of a serious outbreak.

A Scottish Agricultural Colleges study of 212 scour outbreaks affecting more than 3600 sick calves found that for every 50 calves challenged by infectious scour, 24 became ill and started costing money.

Total cost of scour, according to the researchers, was £69 a calf. This included increased cow and calf handling costs, loss in calf value due to reduced liveweight gain and the extra veterinary costs of treatment.

Causes of scour

The single biggest cause of infectious scours of calves in the UK is a virus called Rotavirus. It is found on most farms and is reckoned to affect 90-100% of cattle.

Another cause is coronavirus, which, though less common than rotavirus, has more serious effects. A third factor is the bacterium E coli, which is a leading cause of mortality in calves less than four days old.

Importance of diagnosis

It is vital that you are aware of any disease that may be present in your herd.

Your vet can help by supplying you with a free Schering-Plough Scourwatch testing kit. This allows you to find out if your herd is infected with any of the main causes of infectious scour.

Samples need to be taken within 24 hours of seeing the first signs of scouring and before the animals are treated with antibiotics. Samples are labelled and taken to your vet, who will send them to be tested and pass on the results to you.

ROTAVECCORONA

&#8226 A vaccination programme is the only sure way to prevent future outbreaks of calf scour.
