摘　　要：[目的]通过补饲代乳料提高夏南牛犊牛生长发育速度,培育优质健康犊牛,实现犊牛早期断奶。[方法]犊牛随机挑选并随机分成2个组,试验组使用B配方的饲料,对照组使用A配方的饲料,两组牛分圈饲喂,犊牛与母牛隔离饲养。代乳颗粒料自由采食,采取少给、勤给、逐渐增多的饲喂方法。试验期内测量犊牛体尺、体重,观察不同代乳料的适口性,记录疾病发生种类、次数和频率。[结果]试验组比对照组平均日增重提高17.78%,但差异不显著(P>0.05)。试验组比对照组体高、体斜长、胸围3项体尺分别增加了0.67 cm,1.04 cm和2.05 cm,差异不显著(P>0.05)。腹泻发病率试验组23.08%,对照组22.22%,两组均没有发生其他疫病和死亡。[结论](1)A、B两种代乳颗粒料均可以取代代乳粉,作为夏南牛犊牛的补饲料。(2)较高营养水平的代乳颗粒料,可以提高夏南牛犊牛日增重。试验用代乳颗粒料优于犊牛精料补充料。(3)B配方的代乳颗粒料适口性较好。[Objective] The growth and development rate of Xia’nan cattle can be improved by supplemental feeding. Milk substitution can cultivate high quality healthy calves, and it can be weaned at an early stage.[Method] Calves were randomly selected and divided into two groups(experimental group and control group). The experimental group was fed with formula B feed, while the control group was fed with formula A feed. The calves of the two groups were fed separately. Milk substitution pellet were free to feed, and the feeding method with less,frequently and gradually increasing the giving was adopted. During the trial period, calf body size and body weight were measured. Moreover, palatability of different milk substitution was observed, and typesand the frequency of diseases were recorded.[Result] The average daily weight gain of the experimental group was 17.78% higher than that of the control group, but the difference was not significant(P>0.05). Compared with the control group, the body height, body oblique length and chest circumference of the experimental group increased by 0.67 cm, 1.04 cm and 2.05 cm, respectively, with no significant difference(P>0.05). The incidence of diarrhea was 23.08% in the experimental group and 22.22% in the control group.[Conclusion](1) Both A and B milk substitution granules can replace the milk substitution powder and can be used as supplementary feed for Xia’nan cattle.(2) The substitution milk pellets with higher nutrition level can improve the daily weight gain of Xia’nan cattle. The milk substitution granule was superior to calf concentrate.(3) Formula B had good palatability for substitute milk granules.
