摘要 试验旨在研究初乳巴氏杀菌与否对犊牛生长性能及胃肠道发育的影响。选取体重相近、健康状况良好的20头新生荷斯坦牛犊牛,随机分为2组,对照组犊牛饲喂未经过巴氏杀菌的初乳,试验组犊牛饲喂经过巴氏杀菌的初乳,试验期90d。试验期间测量两组犊牛体重、平均日增重(ADG)、平均日采食量(ADFI)及料重比(F/G),同时观察犊牛腹泻情况,在0、30、60及90日龄测量两组犊牛体尺指标。结果显示,在90日龄时,与对照组相比,试验组犊牛的平均日采食量和平均日增重分别增加了1.74%和2.33%(P〉0.05),试验组犊牛管围和体斜长分别增加了2.68%和1.41%(P〉0.05),而腹泻率和料重比却分别降低了0.67%和2.40%(P〉0.05)。初乳巴氏杀菌与否对犊牛复胃重、小肠重及小肠长度的影响不显著(P〉0.05),但显著降低了犊牛复胃重与活体重比(P〈0.05)。综上所述,巴氏初乳对90日龄内犊牛的生长发育有一定促进作用。 The effects of pasteurized colostrum on growth performance and development of the gastrointestinal tract of calves were studied in this test. Twenty healthy newborn Holstein calves with similar body weight were randomly divided into two groups. The calves in control group were fed non-pasteurized colostrum while that in experimental group were fed on pasteurized colostrum. The experiment lasted for 90 days. The body weight,average body gain (ADG),average daily feed intake (ADFI),F/G and diarrhea rate were determined and at 0,30,60 and 90 days old,the body indexes were measured. The results showed that compared with control group,the ADFI and ADG of calves at 90 days old in experimental group were increased 1.74% and 2.33% (P〉 0.05),and cannon circumference and body length were increased 2.68% and 1.41% (P〉 0.05),while the diarrhea rate and F/G were decreased 0.67% and 2.40% (P〉 0.05).There was no significant effect of pasteurized colostrum on the complex stomach weight,small intestine weight and small intestine length (P〉 0.05). However,the ratio of complex stomach weight to body weight in control group was significantly higher than that of experimental group (P〈 0.05). In conlusion,the pasteurized colostrum had a positive impact on growth performance for calves in 90 days old.
