摘　　要：试验研究了半胱胺(Cs)对藏绵羊羔羊初生重及断奶重的影响。将20只妊娠(125±5)d的母羊随机分为2组(试验组和对照组),在试验组日粮精料中添加300 mg/(kg·BW)的Cs,隔日添加1次,试验期90 d。于分娩后及时将初生羔羊称重,哺乳2个月强制断奶并称重。试验结果表明,试验组精料中添加Cs使藏绵羊羔羊初生重提高8.33%,2月龄断奶重提高13.73%。The effects of cysteamine（Cs） on the birth weight and weaning weight of Tibetan Sheep lamb were studied. 20 pregnant ewes with the age of （125±5）d were randomly divided into 2 groups （test group and control group）. 300 mg/（kg·BW） of Cs was added in the diet concentrate in test group every two days. The test period lasted for 90 days. The birth weight was measured after parturitionand two-month-old lambs was weaned and weighted.
