摘　　要：本试验旨在探讨N-氨甲酰谷氨酸(N-carbamylglutamate,NCG)和精氨酸(Arg)对京海黄鸡肉仔鸡生长性能、血清生化参数及游离氨基酸含量的影响。选用1日龄体重相近的京海黄鸡肉仔鸡600只,随机分为5组,每组6个重复,每个重复20只。对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组饲喂在基础日粮中分别添加0.05%、0.10%、0.15%NCG及0.10%Arg的试验日粮。试验期28d。结果表明,与对照组相比,添加0.05%、0.10%、0.15%NCG及0.10%Arg组平均日增重(ADG)升高,添加0.10%NCG组料重比(F/G)显著降低(P<0.05);添加0.10%NCG组血清中血氨(AMM)、尿酸(UA)和低密度脂蛋白(LDL)含量相对于其他各组显著降低(P<0.05),添加0.15%NCG组血清中一氧化氮(NO)、一氧化氮合成酶(NOS)和碱性磷酸酶(ALP)含量显著高于对照组(P<0.05);与对照组相比,添加0.10%、0.15%NCG组和添加0.10%Arg组血清中Arg含量显著升高(P<0.05)。综上所述,日粮中添加NCG有助于提高京海黄鸡肉仔鸡血清中Arg和脯氨酸(Pro)的含量,改善血液指标,提高肉仔鸡的生长性能,其中NCG添加水平为0.10%时效果较好。This study was conducted to investigate the effects of N-carbamylglutamate （NCG） and arginine （Arg） on growth performance,serum biochemical indexes and serum free amino acid con- tent of Jinghai Yellow broiler chicks. A total of 600 1-day-old chicks with similar weight were used and randomly assigned into 5 groups with 6 replicates per group and 20 chicks per replicate. The control group was fed with basal diet,groups Ⅰ to Ⅳwere fed with the basal diets supple- mented with 0.05%,0. 10%,0. 15% NCG and 0. 10% Arg, respectively. The trial lasted for 28 days. The results showed that compared with control group, the supplementation of 0. 05%, 0.10% ,0.15% NCG and 0.10% Arg increased ADG,the supplementation of 0.10% NCG signifi- cantly decreased F/G （P〈0.05）. The supplementation of 0.10 %NCG significantly decreased the contents of AMM,UA and LDL in serum compared with other groups （P〈0.05） ,the supplemen- tation of 0.15% NCG significantly increased the contents of NO,NOS and ALP in serum com-pared with control group （P〈 0. 05）. Compared with control group, the supplementation of 0.10%,0.15% NCG and 0. 10% Arg significantly increased the content of Arg in serum （P〈 0.05）. These results indicated that supplementation with NCG could increase the contents of Arg and Pro in serum, improve blood parameters and growth performance of broiler chicks, and the ap- propriate supplemental level of NGG was 0.10%.
