酸奶补饲对早期断奶仔猪生长性能的影响

Effects of yogurt supplementation on growth performance of early weaned piglets

试验旨在探究酸奶补饲对早期断奶仔猪成活率、增重率、腹泻率等指标的影响。试验选择同一批次上产床的20窝母猪所产仔猪,随机分成两组,每组10窝,分别为试验组(仔猪补饲固体教槽料以及酸奶)和对照组(仔猪补饲固体教槽料)。试验期21 d。结果显示,试验组仔猪窝死淘率和腹泻数均显著低于对照组(P<0.05)。试验组仔猪窝增重为(48.31±6.64)kg,显著高于对照组(P<0.05)。试验组和对照组仔猪的窝采食量与窝料重比差异均不显著(P>0.05)。研究表明,酸奶补饲的仔猪平均增重、死淘率等方面均优于对照组仔猪。

The experiment was conducted to investigate the effects of yogurt supplementation on survival rate,weight gain rate and diarrhea rate of early weaned piglets.Piglets from 20 litters of sows on the same batch were randomly divided into two groups with 10 litters per group,which were experimental group(piglets were supplemented with solid feed and yogurt)and control group(piglets were supplemented with solid feedstock),respectively.The experiment lasted for 21 d.The results showed that the litter death rate and diarrhea number of piglets in experimental group were significantly lower than those in control group(P<0.05).The litter weight gain of experimental group was(48.31±6.64)kg,which was significantly higher than that of control group(P<0.05).There was no significant difference in litter intake and litter feed to gain ratio between experimental group and control group(P>0.05).The study indicates that the average weight gain and death rate of piglets supplemented with fermented yogurt are better than those in control group.
