【摘要】:为研究饲喂代乳粉对早期断奶犊牦牛生长性能的影响以及产生的经济效益,试验选用30日龄,体重(26±2.6)kg犊牛30头,随机分成3组,每组10头犊牛,每组公母各半,Ⅰ、Ⅱ组分别饲喂高蛋白含量代乳粉、高脂肪代乳粉,对照组按传统方法进行母乳喂养。结果表明:饲喂代乳粉能显著提高早期断奶犊牦牛的体增重和日增重(P0.05);饲喂代乳粉对早期断奶犊牦牛的体高、体斜长和胸围没有显著影响(P0.05);犊牦牛早期断奶能显著提高母牦牛的发情率、受胎率(P0.05),缩短牦牛生产周期,显著提升代乳粉饲喂阶段的经济效益(P0.05)。综合分析,饲喂代乳粉对早期断奶犊牦牛无论在犊牛生产性能方面还是经济效益方面都有显著效果,应在生产中推广应用。
