摘　　要：本试验旨在研究牛磺酸对笼养蛋雏鸭生长性能、抗氧化功能及免疫器官发育的影响。试验采用单因素完全随机分组设计,选择健康1日龄金定蛋雏鸭240只,随机分为5个组(每个组6个重复,每个重复8只鸭),分别饲喂在玉米-豆粕型基础饲粮基础上添加0.05%、0.10%、0.15%、0.20%牛磺酸的试验饲粮。试验期4周。结果表明:饲粮中添加0.10%的牛磺酸可显著提高蛋雏鸭的平均日增重(ADG),降低料重比(F/G)(P<0.05)。同时,饲粮中添加0.10%的牛磺酸还可显著提高肝脏中超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性,总抗氧化能力(T-AOC)以及法氏囊和脾脏指数(P<0.05),并显著降低肝脏中丙二醛(MDA)含量(P<0.05),但对血清中SOD、GSH-Px活性,T-AOC以及胸腺指数无显著影响(P>0.05)。结果提示,饲粮中添加0.10%的牛磺酸可显著改善笼养蛋雏鸭的生长性能,提高机体的抗氧化功能,促进免疫器官的发育。The experiment was conducted to study the effects of taurine on growth performance,antioxidant function and immune organ development of caged egg-type ducklings.Using a single factor completely randomized design,a total of 240 one-day-old Jinding egg-type ducklings were randomly assigned to 5 groups with 6 replicates per group,and each replicate contained 8 ducks.All the egg-type ducklings were fed corn-soybean meal basal diets supplemented with 0,0.05%,0.10%,0.15% and 0.20% taurine,respectively.The experimental period lasted for 4 weeks.The results showed as follows： supplementation of 0.10% taurine significantly improved average daily gain（ADG）,and reduced the ratio of feed to gain（F/G） of egg-type ducklings（P0.05）.Meanwhile,the activities of superoxide dismutase（SOD） and glutathion peroxidase（GSH-Px） and total anti-oxidation capability（T-AOC） were increased,while malondialdehyde（MDA） content was decreased significantly in liver（P0.05）.The bursa of Fabricius index and spleen index were elevated significantly（P0.05）.The activities of SOD and GSH-Px,T-AOC in serum,and the thymus index were not significantly affected by supplementation of 0.10% taurine（P0.05）.In conclusion,supplementation with 0.10% taurine in diets can improve the growth performance,antioxidant function and the development of immune organs of caged egg-type ducklings.
