The objective of this study was to investigate the effects of freeze dried placentasupplementation on reproductive performance, colostrum and plasma biochemical composition inpregnant sows. Eleven Landrace × Large white sows were fed with corn-soybean meal dietssupplemented with or without 1% freeze dried placenta powder from 10 days before theirexpected farrowing dates until 10 days postpartum. The colostrum protein content wassignificantly higher(P=0.043) in the treatment group than in the control group. Compared to thecontrol group, the immunoglobulin G(IgG) concentration in the colostrum was significantlyhigher(P=0.004) in the treatment. In day 25 piglets plasma, the IgG concentration washigher(P=0.184) in the treatment than the control. The mortality rate was lower(P=0.102), andthe piglet weight gain was higher(P=0.35) in the treated group. Overall, the treatment groupshowed greater levels of protein and IgG concentration in the colostrum, when compared tocontrol group. Therefore, the freeze dried placenta supplementation on pregnant sows canenhance its colostrum composition, hence decrease the mortality and increase the growth rate ofpiglets.
