摘要: 【目的】研究N-氨甲酰谷氨酸(N-carbamylglututamate,NCG)在产蛋后期麻黄鸡中的最适添加剂量,为NCG在地方特色蛋鸡生产中的科学应用提供理论依据和实践指导。【方法】选取70周龄淮南麻黄鸡360只,随机分成4组,每组6个重复,每个重复15只。对照组提供基础饲粮,试验组在基础饲粮中添加0.5、1.0和1.5 g/kg NCG。试验期42 d。试验期间记录产蛋数、蛋重和日采食量;于试验第21、42天,收集所有鸡蛋测定蛋品质;试验结束时,每个重复选3只鸡采集血清和肝脏样品,测定生化及抗氧化指标。【结果】与对照组相比,NCG添加量为1.0 g/kg时,淮南麻黄鸡的产蛋率显著提高(P<0.05),蛋黄中甘油三酯(TG)、总胆固醇(T-CHO)含量以及超氧化物歧化酶(SOD)活性均显著提高(P<0.05),丙二醛(MDA)含量显著降低(P<0.05),血清中一氧化氮合成酶(NOS)活性显著提高(P<0.05),肝脏中SOD活性和一氧化氮(NO)含量显著提高(P<0.05);当NCG添加量为1.5 g/kg时,蛋鸡的产蛋率、平均蛋重、蛋黄颜色和蛋壳厚度均显著提高(P<0.05),蛋黄中的SOD活性显著提高、MDA含量显著降低(P<0.05),血清中的NO含量和NOS活性显著提高(P<0.05)。【结论】在基础饲粮中添加NCG可显著提高产蛋后期淮南麻黄鸡的生产性能、蛋品质和抗氧化能力,其中以1.0 g/kg的添加剂量为最佳。

Abstract: 【Objective】 This experiment aimed to investigate the optimal supplementation dosage of N-carbamylglututamate(NCG) in laying hens during the late laying period,thereby providing theoretical foundations and practical guidance for the scientific application of NCG in the production of local specialty laying hens.【Method】 A total of 360 Huainan patridge chickens at 70 weeks of age were randomly divided into four groups,each group has 6 replicates,with 15 individuals per replicate.The chickens in experimental groups were fed diets supplemented with 0.5,1.0,and 1.5 g/kg NCG in the basal diet,respectively.The test period was 42 days.Egg production,egg weight,and daily feed intake were recorded throughout the experiment.During the experiment,egg production,egg weight,and daily feed intake were recorded.On days 21 and 42 of the experiment,all eggs were collected to measure egg quality.At the end of the experiment,3 hens were selected per replicate to collect serum and liver samples for biochemical and antioxidant analysis.【Result】 Compared with the control group,when NCG was added at 1.0 g/kg,the egg production rate of Huainan patridge chickens was significantly increased (P<0.05),the yolk’s triglyceride (TG) and total cholesterol (T-CHO) contents,as well as superoxide dismutase (SOD) activity,were all significantly increased (P<0.05),while malondialdehyde (MDA) content was significantly decreased (P<0.05).The activity of nitric oxide synthase (NOS) in serum was significantly increased (P<0.05),and the activity of SOD and the content of nitric oxide (NO) in liver were significantly increased also (P<0.05).When NCG was added at 1.5 g/kg,the egg production rate,average egg weight,yolk color and eggshell thickness of laying hens were significantly increased (P<0.05),the activity of SOD in egg yolk was significantly increased,while the content of MDA was significantly decreased (P<0.05).The content of NO and the activity of NOS in serum were significantly increased (P<0.05).【Conclusion】 Supplementing the basal diet with NCG significantly improved the production performance,egg quality and antioxidant capacity of Huainan patridge chickens in the late laying period,with 1.0 g/kg identified as the optimal dosage.
