【摘要】：试验旨在研究日粮添加复合酸化剂对生长期海兰褐蛋雏鸡生长性能、免疫性能和血清中抗氧化指标的影响。试验选取3周龄海兰褐蛋雏鸡120只,随机分为2组,每组6个重复,每个重复10只鸡。对照组饲喂基础日粮,试验组饲喂添加0.2%复合酸化剂的基础日粮,试验期为35 d。结果:生长期海兰褐蛋雏鸡日粮中添加复合酸化剂可以改善饲料利用率,但对雏鸡的平均日增重无显著影响(P0.05);添加复合酸化剂可以显著降低生长前期蛋雏鸡血清中丙二醛(MDA)水平,显著提高血清中超氧化物歧化酶(SOD)(P0.01)和铜蓝蛋白(CP)(P0.05)含量;能够显著降低生长早期蛋雏鸡血清中IgM的含量,显著提高生长后期血清中IgG的含量(P0.01)。提示:在生长期蛋雏鸡饲料中添加复合酸化剂,对改善雏鸡的免疫性能及血液中抗氧化指标具有一定的促进作用。
[Abstract]:The purpose of the experiment was to study the effects of dietary compound acidifier on growth performance, immune performance and serum antioxidant index of Hailan brown egg chicks.120 Hailan brown egg chicks aged 3 weeks were randomly divided into 2 groups with 6 replicates in each group and 10 chickens in each replica.The control group was fed basic diet and the experimental group was fed with 0.2% compound acidifier for 35 days.Results: the feed utilization rate was improved by adding compound acidifier to the diet of Hailan brown egg chicks during the growing period.But the average daily gain of chicks was not significantly affected by adding compound acidifier, the level of malondialdehyde (MDA) in serum and the content of superoxide dismutase (SOD) and ceruloplasmin (P0.05) in serum were significantly decreased.It could significantly decrease the content of IgM in serum of early growing egg chicks and increase the content of IgG in serum of late growth stage.It was suggested that adding compound acidifier to the feed of the growing egg chicks could improve the immune performance of the chicks and the antioxidant index in the blood.
