摘　　要：在青海河南县进行欧拉羊母羊补饲营养舔砖试验,结果表明,补饲期间前期40d增重3.50kg,增重率为7.98%;试验后期40d增重4.80kg,增重率为10.13%;补饲期总增重8.30kg,增重率为18.92%。对照组羊前期40d增重-0.67kg,增重率为-1.54%;后期40d增重3.87kg,增重率为9.03%;对照组羊总增重3.20kg,增重率为7.35%。试验组比对照组平均日增重提高63.75g,经济效益提高106.25%。The nutrition lick block experiment of supplementation of Euler ewe was conducted in Henan County,Qinghai Province.The results showed that the weight gain of ewes was 3.50kg and the weight gain rate was 7.98%within 40d of supplementation.In the last 40 days of the experiment,the weight gain was 4.80kg,and the weight gain rate was 10.13%.In the whole period of supplementation,the total weight gain was 8.30kg and the weight gain rate was 18.92%respectively.Comparing with the control group,the weight gain of the control group was-0.67kg in the first 40 days,and the weight gain rate was-1.54%.In the later 40 days,the weight gain was 3.87 kg,and the weight gain rate was 9.03%.The total weight gain of the control group was 3.20kg,and the weight gain rate was 7.35%.The average daily gain of the experimental group was 63.75g higher than that of the control group.The economic benefit increased by 106.25%.
