Bovilis^® Rotavec^® Corona Questions and Answers

For the active immunisation of pregnant cows and heifers to raise antibodies against E. coli adhesins F5 (K99) and F41, rotavirus and coronavirus. While calves are fed colostrum from vaccinated cows during the first two to four weeks of life, these antibodies have been demonstrated to:

• Reduce the severity of diarrhoea caused by E. coli F5 (K99) and F41
• Reduce the incidence of scours caused by rotavirus
• Reduce the shedding of virus by calves infected with rotavirus or coronavirus.

​Onset of Immunity: Passive protection against all active substances will commence from the start of colostrum feeding.

Duration of Immunity: In calves artificially fed with pooled colostrum, protection will continue until colostrum feeding ceases. In naturally suckled calves, protection against rotavirus will persist for at least 7 days and against coronavirus for at least 14 days.
