本试验旨在研究L-精氨酸(Arg)和α-酮戊二酸(AKG)对热应激肉鸡肠道功能的影响。选用200只1日龄Cobb肉鸡,随机分为4个处理组:对照组(基础日粮)、热应激组(基础日粮)、Arg组(基础日粮+0.5%Arg)、AKG组(基础日粮+0.5%AKG),每个组5个重复,每个重复10只鸡。试验为期5周,第1周各组室温控制在32~34℃,第2~5周热应激组、Arg组和AKG组控制在(36±2)℃,而对照组第2周开始慢慢降至(22±2)℃,并从第3周开始维持在(22±2)℃,湿度为50%~60%。结果表明:与对照组相比,热应激处理降低了肉鸡生长性能和血液三碘甲腺原氨酸(T3)含量(P

This study was conducted to investigate the effects of arginine and α-ketoglutaric acid on intestinal function of heat-stressed broilers. 200 1-day-old Cobb chickens were randomly divided into four groups （control group, heat- stress group, Arg group, and AKG group）. Each treatment had 5 replicate pens with 10 chickens per pen. The control group and heat-stress group were fed a basal diet, whereas Arggroup were fed basal diet ＋ 0.5% Arg and AKG group were fed basal diet ＋0.5% AKG. The heat-stressed process was followed as： first week 32-3...
