High progesterone levels at farrowing impair colostrum IgG concentration and colostrum yield in sow
Published:February 15, 2018
Summary
Introduction Lactogenesis is induced hormonally by a dramatic drop of progesterone (P4) concentrations which leads to a pre-partum peak of prolactin (PRL). In sows, impaired production of colostrum has been found to be related to a delay in the decrease of P4 concentrations during the pre-partum period. We assumed that this condition might affect also the quality of colostrum (IgG concentrati...
