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.
• A vaccination programme is the only sure way to prevent future outbreaks of calf scour.
• Effective protection against rotavirus, coronavirus and E Coli begins 3-12 weeks before calving by vaccinating with Rotavec Corona.
• Unlike a vaccine requiring two injections, single shot Rotavec Corona can be administered any time during the three to 12 weeks before calving.
What is the total cost a calf of scour, according to the SAC research?
