不同断奶日龄对羔羊增重效果的影响

Effect of Different Weaning Age on the Weight Gain of Lambs

对50日龄的60只杜湖杂交羔羊开展不同断奶日龄对羔羊育肥效果的影响试验,结果得出75日龄断奶,羔羊对饲料的适应性强,后期生长发育和抗病能力优于60日龄与90日龄,增重效果较好,为当地杜湖杂交羔羊最佳断奶时间。

60 Dorper sheep and Hu sheep crossbred lambs of 50 days old were tested on the effect of different weaning days on fattening of lamb.The results showed that 75 days old weaned lambs had a strong adaptability to feed,and their later growth and disease resistance were better than those of 60 days old and 90 days old.The weight gain effect was better,which was the best weaning time for local Dorper sheep and Hu sheep crossbred lambs.
