Colostrum and Milk Immunoglobulins Increase in Sows Fed Live Saccharomyces cerevisiae boulardii

摘要

The acquisition of passive immunity by the newborn piglet is necessary because it provides a high level of immune protection, therefore improving the development of piglet’s active immunity during lactation and its level of systemic immunity at weaning (Le Dividich et al., 2005). The acquisition of passive immunity depends mainly on the amount of colostrum consumed, and on its immunoglobulin G (IgG) content. Live yeast fed to the sow has been shown to improve the IgG plasma level in their 24h old piglets in a dose dependent manner (Jang et al., 2010), suggesting an increased colostral IgG concentration and /or colostrum production of the sows. This experiment tests the hypothesis that sows fed live Saccharomyces cerevisiae boulardii CNCM I-1079 (SCB) produce more immunoglobulins in colostrum and milk.
