Virbac has announced that Bovigen Scour, its vaccine for the immunisation of pregnant cows and heifers to raise antibodies against E.coli F5 (K99), rotavirus and coronavirus, has had the shelf life on its SPC increased from 10 hours to 10 days. 

The broached bottle must be kept refrigerated between 20C and 80C until the next use.

Virbac says that whilst this may not seem a huge change, it significantly increases the cost-effectiveness and convenience to farmers.

The SPC changes mean that 

  • cows do not have to be handled all at the same time or treated on the same day.
  • farmers can use larger vials and the vial does not have to be thrown away after the first broach so there is less wastage.
  • there is more opportunity for farmers to vaccinate more of their dams, reducing the effects of neonatal calf diarrhoea.

Bovigen Scour is available in 5 and 30 dose bottles.
