摘要: 本试验采用东北细毛羊羔羊32只,均为雌性,随机分成4组,其中一组为对照组,饲喂基础日粮,其余3组分别在日粮中添加半胱胺75、125、175 mg/kg。试验结果表明,添加125 mg/kg的试验组最佳,使羔羊平均日增重提高20.96%(P≤0.01),平均毛长增长提高31.51%(P≤0.01),料肉比降低15.79%(P≤0.01),平均日收入提高66.07%(P≤0.01)。

Abstract: In this test ,32 female Kids of the Fuzz-Wooled Sheep in the Northeast China are divided into four groups at random one of which was used as the contrast group and fed with the basic daily food supplies and the remaining 3 groups were fed with 75,125,175 mg/kg Cysteamine in the daily food supplies respectively . The findings indicate that on average, the test group with 125 mg/kg Cysteamine produced the best result of enabling the kids to increase their weight by 20.96%(P≤0.01)every day and the wool length by 31.51%(P≤0.01), decrease the ratio of the feed to the pork by 15.79%(P≤0.01) and increased the daily income by 66.07%(P≤0.01).
