紫花苜蓿添加对牦牛生长性能及消化率的影响

摘要

In order to cultivate yaks with alfalfa green hay, the effects of Alfalfa addition on growth performance of yaks was studied.The results showed that alfalfa feeding yak had significant weight gain effect, and the daily weight gain of the yak was significantly higher than that of oat green hay and control group (P＜0. 05). At the same time, the digestibility of feed in alfalfa feeding group was significantly higher than that in other groups (P ＜ 0. 05). The economic benefits of alfalfa treatment group were significantly better than other groups, which was an ideal yak forage combination.%开展了紫花苜蓿添加对牦牛生长性能的影响试验.结果表明:紫花苜蓿饲喂牦牛增重效果明显,头均日增重显著(P＜0.05)高于燕麦青干草和对照处理组.同时,紫花苜蓿饲喂处理组饲料消化率显著高于(P＜0.05)其他组.综合分析经济效益,紫花苜蓿处理组经济效益显著(P＜0.05)优于其他饲草处理组,是较为理想的牦牛饲喂饲草组合.
