摘　　要：为考察发酵黄芪茎叶饲喂肉羊的应用效果,将挑选的黄芪茎叶揉碎与黄豆粉、麦麸、玉米面、解淀粉芽孢杆菌等混合发酵,替代50%的粗饲料饲喂肉羊,粗饲料成本从360元/t降为340元/t,粗饲料成本减少了20元/t,降低了5.56%;通过对356只小尾寒羊90 d的饲喂,试验组羊平均日增重比对照组羊增加了0.02 kg,提高了8.7%,试验组与对照组相比差异极显著(P<0.01);整个试验期间,试验组羊发病率比对照组羊减少了6.74%;试验组羊净收入比对照组羊多36.55元/只,增加经济效益10.53%。说明发酵黄芪茎叶饲喂肉羊可以降低肉羊饲料成本,提高肉羊饲料利用率,增加肉羊增重,增强肉羊机体免疫力。In order to investigate the application effect of fermented Astragalus membranaceus stems and leaves on feeding meat sheep,the selected Astragalus membranaceus stems and leaves were crushed and mixed with soybean flour,wheat bran,corn flour,and Bacillus amyloliquefaciens for fermentation,replacing 50%of the crude feed to feed meat sheep.The cost of crude feed was reduced from 360 yuan/t to 340 yuan/t,and the feed cost was reduced by 20 yuan/t,a decrease of 5.56%;After feeding 356 small tailed Han sheep for 90 days,the average daily weight gain of the experimental group increased by 0.02 kg compared to the control group,an increase of 8.7%.The difference between the experimental group and the control group was extremely significant(P<0.01);During the whole test period,the incidence rate of sheep in the test group and the incidence rate of sheep in the control group decreased by 6.74%;The net income of the experimental group sheep was 36.55 yuan/sheep more than that of the control group sheep,increasing economic benefits by 10.53%.Feeding fermented Astragalus membranaceus stems and leaves to meat sheep can reduce feed costs,improve feed utilization efficiency,increase weight gain,and enhance the immune system of meat sheep.
