试验旨在研究α-酮戊二酸对热应激肉鸡生长性能和肌肉品质的影响.通过给高温应激肉鸡饲喂含0.5％ α-酮戊二酸(α-ketoglutarate,AKG)的日粮35 d,研究AKG对热应激肉鸡生长性能、肌肉品质、抗氧化功能和能量代谢的影响.结果表明:①与对照组相比,热应激处理显著降低了肉鸡(1～35日龄)的生长性能(P＜0.05)和组织(胸腺、肝脏、胸肌和腹脂)的相对重量(P＜0.05),同时也降低了肉鸡胸肌的a值、抗氧化酶(过氧化氢酶CAT和谷胱甘肽过氧化物酶GSH-Px)的活力、三磷酸腺苷(ATP)和二磷酸腺苷(ADP)含量及能荷(EC)值,但是提高了肉鸡胸肌一磷酸腺苷(AMP)的含量(P＜0.05).②日粮中添加0.5％的AKG降低了热应激肉鸡的...

This study was conducted to investigate the effects of α-ketoglutarate（AKG） on growth per-formance, meat quality, antioxidative function, and energy metabolism of broilers under heat stress.Two hundred 1-day-old Cobb chickens were randomly divided into four groups（control group, heat-stress group, VC group, and AKG group）. Broilers in control group were fed the basal diet, and the VCand AKG groups were fed the basal diet supplemented with 0.025% vitamin C and 0.5% AKG, respec-tively. The feeding trial lasted for 35 days. The results showed...
