【摘要】Tibetan sheep were divided into four groups after lambing and supplemented for 90 d. The results showed that group I with only feeding high quality fresh dry forage of 0.5kg every day inereased 1.57kg and
5.29kg respecti - rely in body weight for ewes and lambs. Group II with only feeding concentrate of 0.25kg every day increased 2.36kg and 7.9kg respectively in body weight for ewes and lambs. Group III with only feeding concentrate of 0.5kg every day increased 4.25kg and 10.02kg respectively in body weight for ewes and lambs. Group 1V with only feeding nutritional lick-block of 0.15kg every day increased 1.7kg and
6.51kg respectively in body weight for ewes and lambs. The four test groups are effective in protecting ewes fat and lamb survival. The gaining weight of group III in ewes and Iambs were highest and feed costs was also highest; Gaining weight of group I ewes and lambs were at least, supplementary cost was the lowest.%藏系绵羊在产羔后分为4组,进行为期90天的补饲试验,结果：试验1组只均日补饲优质青干草0.5 kg,母羊和羔羊的增重分别为1.57kg和5.29kg;试验2组只均日补饲精料0.25kg,母羊和羔羊的增重分别为2.36 kg和
7.9kg;试验3组只均日补饲精料0.5kg,母羊和羔羊的增重分别为4.25 kg和10.02kg;试验4组只均日补饲营养添砖0.15kg,母羊和羔羊的增重分别
为1.7kg和6.51kg。

4个试验组均达到了母羊保膘和羔羊成活的目的。

其中,第3组母羊和羔羊的增重最高,饲料成本也最高;第1组母羊和羔羊的增重最少,但补饲成本最低。
