Abstract: 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 content 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 Ⅳ were fed with the basal diets supplemented 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 significantly 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 supplementation of 0.15% NCG significantly increased the contents of NO, NOS and ALP in serum compared 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 appropriate supplemental level of NGG was 0.10%.
