摘　　要：为研究酸化奶小群饲养技术对犊牛生长性能及腹泻率的影响,选择初生体重36~50 kg的40头母犊牛,采用完全随机设计,将犊牛分为对照组和试验组,对照组采用单栏饲养,定时定量饲喂常乳,试验组采用小群饲养,自由采食酸化奶,分析两组犊牛采食量、日增重和腹泻情况的差异,试验期65 d。结果表明,与对照组相比,试验组犊牛的液体饲料(酸化奶)采食量极显著提高61.85%(P<0.01),颗粒料采食量差异不显著(P>0.05),平均断奶日增重极显著提高30.43%(P<0.01),犊牛腹泻发病率降低25个百分点,腹泻频率降低17.75个百分点。综合说明,饲喂酸化奶可显著提高犊牛生长性能,降低腹泻率。To study the effects of small group feeding technology with acidified milk on calves growth performance and diarrhea rate,the experiment was conducted with the completely random design,40 female calves at the birth weight of 36-50 kg were divided into control group and experimental group randomly.The control group adopted single bar feeding,quantitative feeding ordinary milk regularly,while the experimental group adopted small group feeding,feeding acidified milk freely,the differences in feed intake,daily gain,and diarrhea rate between the two groups were analyzed.The experiment lasted for 65 days.The results showed that compared with the control group,the calves'feed intake of acidified milk in the experimental groups was significantly increased by 61.85%(P<0.01),the feed intake of pellet feed had no significant difference(P>0.05),the average daily gain was significantly increased by 30.43%(P<0.01),the incidence of diarrhea was decreased by 25 percentage points,and the frequency of diarrhea decreased by 17.75 percentage points.In conclusion,feeding acidified milk could significantly improve growth performance and reduce diarrhea rate of calves.
