摘　　要：为研究半胱胺对肉鸡生产性能、屠宰性能的影响，试验选择1日龄罗斯308肉鸡90只，随机分为2组，每组3个重复，每个重复15只，分别在日粮中添加0（对照组）、100mg／k（试验组）半胱胺。饲养42d后，测定肉鸡的生产性能、屠宰性能。结果表明：与对照组相比，试验组22—42d及试验全期日增重显著提高（P〈0．05），料重比显著降低（P〈0．05）；饲养42d后，试验组屠宰率、胸肌率显著提高（P〈0．05），腹脂率显著降低（P〈0．05）。由此可见，肉鸡日粮中添加100mg／kg半胱胺可提高肉鸡生长性能和屠宰性能。This experiment was conducted to investigate the effect of cysteamine on growth performance and slaughter performance of broilers. 90 1-day-old Rose broilers were randomly divided into 2 treatments with 3 replications of 15 each.The control group and trial group were added 0,100 mg/kg cysteamine ,respectively.The test period was 42 days.The production performance and slaughter performance of broilers were determined.The results showed that：compared with the control group,the average daily gain （ADG） and feed convertion rate （FCR） of the trail group in 22 - 42 days and whole period siginificantly increased（P 〈 0.05） ;slaughter rate, chest muscle rate of the trial group siginificantly raised（P 〈 0.05） and abdominal fat rate siginificantly reduced at 42 day（P 〈 0.05）.In conclusion, 100 mg/kg cysteamine in diet could im- prove growth production and slaughter performance of broibers.
