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.
