摘要/Abstract

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%。

Abstract: 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. The results showed that adding Cs in the diet concentrate in test group could enhance the birth weight by 8.33%and the weaning weight of 2-month-old was increased by 13.73%.
