摘　　要：以鹌鹑为研究对象,于日粮中添加不同剂量（0,100,500 mg/kg）的牛磺酸（Tau）,考察Tau对鹌鹑生产性能、免疫功能及抗氧化能力的影响。将300只1日龄鹌鹑分为3个处理组,每个处理组4个重复,每个重复25只,试验6周。结果表明,添加500 mg/kgTau可显著增加鹌鹑0~3 w体增重和3周龄体重,显著降低0~3、3~60、~6 w的料重比（P〈0.05）。Tau可显著增加鹌鹑外周血B淋巴细胞增殖能力,500 mg/kgTau可显著增加T淋巴细胞增殖能力（P〈0.05）。Tau可显著提高血清免疫球蛋白IgG质量浓度（P〈0.05）。添加100 mg/kg Tau可显著提高鹌鹑血清总抗氧化能力,减少血清丙二醛的产生（P〈0.05）。结果显示,日粮中添加牛磺酸可提高鹌鹑的生产性能,通过提高机体的淋巴细胞增殖能力和血清IgG含量增强鹌鹑的免疫功能,牛磺酸可提高鹌鹑的抗氧化能力。In this study,different levels of taurine（0,100,500 mg/kg） were added to the diets and the effects of taurine on production,immune responses and antioxidative ability of quails were investigated.A total of 300 quails were allocated to 3 dietary treatments.Each treatment comprised 4 replicates of 25 quails.The experimental period lasted 6 weeks.The results showed that dietary 500 mg/kg taurine increased body weight of 3 weeks and body weight gain（0~3 week）,decreased feed conversion ratio significantly compared with the control（P0.05）.Dietary taurine increased the ability of stimulation B-lymphocyte proliferation significantly and 500 mg/kg taurine increased the ability of stimulation T-lymphocyte proliferation significantly（P0.05）.Dietary taurine increased serum IgG content significantly compared with the control（P0.05）.Dietary taurine of 100 mg/kg enhanced the activity of total antioxidant capacity（T-AOC） in serum,decreased the malondialdehyde（MDA） level in serum（P0.05）.The above results demonstrated that taurine can increase 1） performance of quails;2） antioxidant ability;3）immune function.
