【摘要】：本试验旨在研究饲粮中添加N-氨甲酰谷氨酸对三黄鸡养分代谢率、屠宰性能和血清免疫球蛋白含量的影响。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,每个重复15只鸡。对照组饲喂基础饲粮,试验1,2,3组分别饲喂N-氨甲酰谷氨酸添加量为0.4%、0.5%、0.6%的试验饲粮。试验期28 d。试验结果表明:(1)N-氨甲酰谷氨酸可以提高粗蛋白质、钙、磷代谢率,其中,添加0.4%、0.5%N-氨甲酰谷氨酸组粗蛋白质代谢率比对照组分别提高6.95%、7.04%(P0.05);添加0.4%、0.5%N-氨甲酰谷氨酸组磷代谢率比对照组分别提高5.38%、2.80%(P0.05)。(2)添加0.4%N-氨甲酰谷氨酸可以显著提高全净膛重、胸肌率、腿肌率、肝脏和肾脏重量(P0.05)。添加0.4%、0.5%组屠宰重比对照组分别提高9.57%、8.82%(P0.05)。添加0.4%N-氨甲酰谷氨酸组胸肌率、腿肌率、肝脏重量比对照组分别提高13.46%、6.08%、9.81%(P0.05)。(3)添加0.4%、0.6%N-氨甲酰谷氨酸组免疫球蛋白A含量比对照组分别提高17.65%、5.88%(P0.05)。添加0.4%、0.5%N-氨甲酰谷氨酸组免疫球蛋白G含量分别比对照组提高33.96%、28.30%(P0.05)。添加0.4%、0.6%N-氨甲酰谷氨酸组免疫球蛋白M含量比对照组分别提高25%、12.5%(P0.05)。综合上述各项指标可知,N-氨甲酰谷氨酸添加的比例在0.4%时能很好的改善三黄鸡养分代谢率和屠宰性能,增加血清中免疫球蛋白的含量。
[Abstract]:The purpose of this study was to study the effects of dietary N-carbamyl glutamate on nutrient metabolism, slaughter performance and serum immunoglobulin content in Sanhuang chickens. 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 group. The control group was fed with basic diet, and the control group was fed with 0.6% N-carbamyl glutamate. The trial period was 28 days. The results showed that the metabolism rate of crude protein, calcium and phosphorus could be increased by N-carbamyl glutamate. Compared with the control group, the crude protein metabolism rate in the addition of 0.40.5N- carbamyl glutamate group was 6.95 higher than that in the control group, respectively, and the P metabolism rate of the 0.45N- carbamyl glutamate group was 5.38% higher than that of the control group, respectively. The addition of 0.4N- carbamylglutamic acid significantly increased the weight of the whole bore, the pectoral muscle rate, the leg muscle rate, the percentage of the leg muscle, and the total weight of the bore, the pectoral muscle rate and the leg muscle rate, respectively. Weight of liver and kidney. Compared with the control group, the slaughtering weight of the 0.5% group increased 9.57% and 8.82%, respectively. Compared with the control group, the pectoralis rate, leg muscle rate and liver weight in the addition of 0.4N- carbamyl glutamate group were increased by 13.466.08 and 9.81% respectively (P 0.05).) the content of immunoglobulin A in the addition of 0.4N-carbamyl glutamate group was 17.65% higher than that in the control group, and the content of immunoglobulin A in the control group was 17.65% higher than that in the control group. The content of immunoglobulin G in the group of 0. 4 and 0. 5% N carbamyl glutamate was 33.96% higher than that of the control group, respectively. The content of immunoglobulin M in the group of 0. 4 and 0. 6% N carbamyl glutamate was increased by 25% than that in the control group, respectively. According to the above indexes, the proportion of N-carbamyl glutamate added in 0.4 can improve nutrient metabolism rate and slaughter performance of Sanhuang chicken, and increase the content of immunoglobulin in serum.
