酵母培养物对母猪繁殖性能的影响

Effects of Yeast Culture on the Reproduction of Gastation Sows

试验研究了在母猪日粮中添加酵母培养物制剂对母猪繁殖性能的影响。研究结果表明,添加酵母培养物制剂可以有效地提高母猪的繁殖性能。试验组母猪的窝产仔数、产活仔数、平均初生体重和平均初生窝重比对照组均有不同程度提高,其中平均初生体重提高10.95%(P<0.05),平均初生窝重提高21.96%(P<0.01);在仔猪哺乳期生产性能方面,各项指标也均有不同程度的提高,试验组仔猪哺乳期平均日增重极显著地高于对照组(P<0.01),提高幅度达23.53%;在仔猪平均断奶体重和平均断奶窝重方面,试验组均显著高于对照组(P<0.05),提高幅度分别达10.71%和15.98%。经济效益可观。

The effects of yeast culture on the reproduction performance of gestation sows and the performance of newborn piglets were studied. The results showed that yeast culture supplementation could effectively improve the reproduction performance of gestation sows. And the litter size could be increased by 8.00% per litter. The average weight of the newborn piglets and their average litter weight could be increased by 10.95% (P<0.05) and 21.96% (P<0.01) respectively. The average daily gain of the piglets, average ablactating litter weight and average ablactating weight per piglet could be improved by 23.53% (P<0.01), 15.98% (P<0.05) and 10.71% (P< 0.05) respectively. The economic benefits would be increased for the addition of yeast culture.
