Blood samples 4 predicted calving (the time treatment), day at 14th after for assessment plasma concentrations. calves drawn jugular vein birth first colostrum also collected. occurrence mastitis evaluated all groups. Higher plasmatic colostral concentrations found only repeat application (D1) collected At postpartal period trend lower observed compared group, once group. Parenteral supplementation had no impact their transmission into presence bacterial raw obtained diagnosed mastitis.
