摘　　要：研究了半胱胺(CS)对雏鸡生长性能的影响。试验选用500羽1日龄草杂雏鸡,随机分成五组,即:试验1组、2组、3组、4组和5组,每组100羽,半胱胺分别按0.5g/kg、1.0g/kg、1.5g/kg、2.0g/kg和0.0g/kg添加到试验1组、试验2组、试验3组、试验4组和试验5组的基础日粮中。试验期为60d。试验结果表明,饲喂添加CS0.5g/kg、1.0g/kg、1.5g/kg日粮的试验1组、试验2组和试验3组雏鸡的日增重较对照组雏鸡高9.0%(p<0.05)、17.3%(p<0.05)和1.5%;饲喂添加CS2.0g/kg日粮的实验4组雏鸡日增重较对照组雏鸡低(p<0.05);试验结果表明,添加CS1.0g/kg日粮能显著提高雏鸡的生长性能。当CS添加量达到2.0g/kg日粮以上时会抑制雏鸡的生长。Effect of Cysteamine （CS）on performance of Chicken were studied in this experiment. 500 oneday-age chickens were used in this experiment. The chickens were randomly divided into five groups by 100/group. CS of 0.5g/kg, 1.0g/kg, 1.5g/kg,2.0g/kg 和 0.0g/kg were added to the basic diet of experiment 1 group, experiment 2 group, experiment 3 group, experiment 4 group and experiment 5 group respectively. The experiment stage was 60 days. The result reveals that the daily weight gain of chicken in experiment 1 group, experiment 2 group and experiment 3 group were increased 9.0% （p〈0.05）, 17.3% （p〈0.05）and 1.5% than the contrast groups, the daily weight gain of chicken in experiment 4 group was decreased than the contrast group （p〈0.05）. The result shows that the CS of 1.0g/kg could enhance performance of chicken.
