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）、100 mg/kg（试验组）半胱胺。饲养42 d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22～42 d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42 d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100 mg/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.
