Effect of vaccination of the dam on rotavirus infection in young calves

  2. EF Logan

Abstract

Vaccination of cows with a combined, inactivated, adjuvanted rotavirus and Escherichia coli vaccine resulted in increased neutralising antibody titres to rotavirus in serum and colostral whey. Evidence was obtained that vaccination resulted in a decreased incidence of rotavirus shedding and of abnormal faeces or diarrhoea in young calves fed colostrum and milk from the vaccinated dams. The E coli component of the vaccine was not evaluated because no natural challenge was evident.
