The study was conducted in a Greek farm of 200 Holstein cows which were immunized with a homologous Neethling strain-based attenuated vaccine. Composite colostrum samples were obtained from 18 selected cows at the day of calving. Blood samples were obtained from each dam- calf pair prior to the first colostrum feeding and from the calves successively on the third day after calving and on monthly intervals thereafter, until day 150. Passive transfer of antibodies in calves was evaluated by determining the levels of total protein in serum samples collected on day 3. Neutralizing antibody (NAb) titers against LSDV in colostrum and serum samples were determined by
