【摘要】：试验旨在研究饲粮中添加N-氨甲酰谷氨酸对三黄鸡生长性能、血清生化指标和血清游离氨基酸含量的影响。选取21日龄体重相近的三黄鸡180只,随机分为4组,每组3个重复,每重复15只鸡。对照组饲喂基础饲粮,试验1、2、3组饲喂在基础饲粮中分别添加0.4%、0.5%、0.6%N-氨甲酰谷氨酸的试验饲粮。试验期28 d。试验结果显示,1添加0.4%N-氨甲酰谷氨酸平均日增重显著高于对照组(P0.05);28~56日龄添加0.4%、0.5%组平均日采食量、料重比显著低于对照组(P0.05)。2与对照组相比,添加0.4%N-氨甲酰谷氨酸组总蛋白、白蛋白含量差异显著(P0.05)。添加0.4%N-氨甲酰谷氨酸组球蛋白含量、碱性磷酸酶活性最高(P0.05)。3与对照组相比,添加0.4%N-氨甲酰谷氨酸组可以显著提高精氨酸、赖氨酸、苏氨酸含量(P0.05)。综合上述各项指标可知,饲粮中N-氨甲酰谷氨酸添加的比例在0.4%时能很好地促进三黄鸡的生长发育,改善血液指标,增加血清部分氨基酸的含量。
[Abstract]:The purpose of the experiment was to study the effects of dietary N-carbamyl glutamate on growth performance, serum biochemical index and serum free amino acid content in Sanhuang chicken. 180 Sanhuang chickens with similar body weight at 21 days old were randomly divided into 4 groups with 3 replicates in each group and 15 chickens in each replica. The control group was fed with basic diet, and the control group was fed with the experimental diet of 0.5 ~ 0.6N- carbamyl glutamate respectively. The trial period was 28 days. The results showed that the average daily gain (ADG) of the control group was significantly higher than that of the control group (P 0.05N 2856 d), and the feed weight ratio was significantly lower than that of the control group (P 0.05C 2), and the total protein content of the control group was significantly lower than that of the control group (P 0.05%). The difference of albumin content was significant (P 0.05). Compared with the control group, the contents of arginine, lysine and threonine were significantly increased in the addition of 0.4 N-carbamyl glutamate group (P 0.05). According to the above indexes, the proportion of N-carbamyl glutamate added in diet can promote the growth and development of Sanhuang chicken, improve the blood index and increase the content of some amino acids in serum.
