倍肽德酵母培养物对母猪泌乳性能的影响试验研究

Effect of Dietary Supplementation of a Commercially Available Yeast Culture Beitaide on Lactation Performance of Sows

为探索母猪哺乳日粮中添加倍肽德酵母培养物替代部分常规饲料原料对母猪泌乳性能的影响,选用品种相同、体重和胎次相近,健康的产前7 d妊娠母猪24头,分成3组,A组为未添加倍肽德酵母培养物的对照组;B组为用倍肽德酵母培养物替代A组配方中5%麸皮的试验组;C组为用倍肽德酵母培养物替代A组配方中2%豆粕和3%的玉米的试验组。结果显示,B组仔猪10日龄、18日龄的均重显著高于其他2组。0~18日龄仔猪平均日增重,B组达230.55 g,A组185.56 g,而C组为178.89 g,B组仔猪平均日增重显著高于A组、C组,比A组、C组仔猪平均日增重分别高24.25%、28.87%;A组、B组、C组仔猪存活率无显著差异,但B组相对其他2组仔猪存活率最高;各组母猪泌乳量的统计结果显示,B组母猪泌乳量显著高于其他2组。母猪哺乳期日粮中合理使用倍肽德酵母培养物,对仔猪生长性能及母猪的泌乳量有一定程度的提升,可提高母猪的泌乳性能。

In order to assess the partial replacement of conventional feedstuff by dietary supplementation of a commercially available yeast culture Beitaide on lactation performance of sows,a total of 24 healthy pregnant sows with the same breed,weight and parity were selected 7 days before delivery and were divided into 3 groups.Group A was the control group without yeast culture,group B was the experimental group with Beitaide yeast culture replacing 5%bran of group A,and group C was the experimental group with Beitaide yeast culture replacing 2%soybean meal and 3%corn of group A.The results showed that the average weight of piglets in group B at 10 and 18 days of age was significantly higher than that in the other two groups.The average daily gain of piglets from 0-to 18-day-old in group B,group A and group C was 230.55 g,185.56 g and 178.89 g,respectively.The average daily gain of group B was significantly higher than that of group A and C by 24.25%and 28.87%,respectively.Although there was no significant difference in survival rate among group A,group B and group C,group B performed better.The group B had significantly better performance in milk yield compared to the other two groups.In conclusion,the rational dietary supplementation of Beitaide yeast culture in lactation period improves the growth performance of piglets and the lactation performance of sows to a certain extent.
