Failure of transfer of passive immunity and agammaglobulinaemia in calves in south‐west <scp>V</scp>ictorian dairy herds: prevalence and risk factors

Abstract

There is considerable potential to improve the transfer of passive immunity in dairy herds in south-west Victoria. The prevalence of both FTPI and agammaglobulinaemia is likely to be reduced by collecting calves from the calving area twice daily and hand-feeding them extra colostrum immediately after their removal from the calving area.
