Effects of Dietary Supplement with Xylo-Oligosaccharide and Active Yeast During Lactation of Sows on Reproduction Performance and Serum Biochemical Indices of Suckling Piglets

This study was conducted to investigate the effects of dietary supplement with xylo-oligosaccharide( XOS) and active yeast( AY) during lactation of sows on reproduction performance and serum biochemical indices of suckling piglets. All 27 healthy sows with similar parity and the expected date of confinement were chose,and randomly divided into 3 groups: control( basal diet),XOS( basal diet+0.03%XOS) and XOS +AY( basal diet+ 0.03%XOS + 0. 05%AY) groups,with 9 replicates per group and 1 sow per replicate. The sows were fed diets starting on day 100 of gestation and throughout the 14 days of lactation experiment. The results showed as follow : 1) dietary supplement with XOS or AY improved weight gain of piglets and milk production of sows. And lactation milk production of the sows from the XOS+AY group was increased by 29.58%( P0.05). 2) At 7 days of age,dietary supplement with XOS significantly increased calcium( Ca) content( P0.01) and significantly decreased aspartate transaminase( AST) activity( P0.05) in serum of piglets. At7 days and 14 days of age,supplementation with XOS and AY significantly increased the contents of glucose( GLU),albumin( ALB),total protein( TP),and total iron binding capacity( TIBC)( P0.05) and significantly decreased ammonia( AMM) content( P0.05) in serum of piglets. 3) At 7 and 14 days of age,serum IgG content were significantly increased by 19.42% and 13.57%( P0.05) of piglets in the XOS+AY group.In conclusion,these results suggest that the dietary supplement with XOS and AY can improve reproduction performance of sows,alleviate stress reaction,and improve immunity of piglets.
