Virbac has launched of Bovigen Scour, an emulsion for injection into cattle which reduces the severity of diarrhoea caused by bovine rotavirus, bovine coronavirus and enteropathogenic E.coli F5 (K99). 

Bovigen Scour works by actively immunising pregnant cows and heifers and providing passive immunity to their calves via colostrum. According to the company, the vaccine also helps to reduce the shedding of virus by calves infected with bovine rotavirus and coronavirus.

Virbac says a key benefit of Bovigen Scour is the vaccination protocol which offers a large window for injection, making it easier for vaccination planning. The primary course is administered in two shots, with first dose between 12 and 5 weeks before calving and the booster 3 weeks later. The annual booster is then due between 12 and 3 weeks before calving is expected. The vaccine is presented in two sizes: 15ml (5 doses) and 90ml (30 doses). The dosage per cow is 3 ml and the withdrawal time is nil in milk.

Virbac Large Animal Product Manager Brigitte Goasduf MRCVS said: "Bovigen Scour offers farmers flexibility and ease of use. The flexibility it gives in terms of scheduling the primary course and booster is particularly important and is highly relevant for beef cattle farmers as it can be difficult to know exactly when a cow is likely to calve and it is vital not to miss the vaccination window.   

"Bovigen Scour is also convenient to give because of the small volume of emulsion and because the injection is given intramuscularly. Its launch extends our large animal vaccine range, which includes Gudair, for the active immunisation of sheep and goats against Mycobacterium avium subspecies paratuberculosis (Map)."
