Dietary yeast culture supplementation can contribute to the performance and health of sows piglets, but few studies have focused on relationships between effects gut microbiota. This study investigated effect (Saccharomyces cerevisiae) from late gestation weaning reproductive lactating their faecal One hundred six purebred Landrace sows, parities two were selected randomly assigned a control (CON) (YC) groups based parity back fat thickness. The YC individually fed with at dose 24 g/d day 90 parturition 40 during lactational period. Blood samples collected d 110 21 lactation for plasma hormone immunoglobulin analysis.
