摘要
本试验研究了牛磺酸对虹鳟仔鱼生长、体成分和免疫指标的影响。试验共分4个处理，分别添加0、500、1 000和1 500 mg/kg牛磺酸，试验共进行12周。结果表明：与未添加牛磺酸组相比，12周时添加1 000 mg/kg组体重、体长和平均日增重显著下降（P〈0.0 5），饵料系数极显著提高（P〈0.0 1）。添加1 5 0 0 mg/kg组体脂肪显著下降（P〈0.0 5）。4周时，添加1 000和1 500 mg/kg组提高超氧化物岐化酶（superoxide dismutase，SOD）和总抗氧化能力（P〈0.05），但酸性磷酸酶却下降（P〈0.05）。添加500（P〈0.05）和1 500 mg/kg组（P〈0.01）丙二醛也升高。添加牛磺酸各组碱性磷酸酶活性显著提高（P〈0.05）。12周龄时，添加1 500 mg/kg组显著降低SOD水平（P〈0.05），添加1 000和1 500 mg/kg组总抗氧化能力也显著下降（P〈0.05），添加牛磺酸各组丙二醛、碱性磷酸酶和酸性磷酸酶显著下降（P〈0.05）。本试验得出，添加500～1 500 mg/kg牛磺酸不能改善虹鳟仔鱼生长性能，但可提高4周时免疫力，但长时间添加（16周）却降低免疫力。
Effects of taurine on growth, body composition and immunity of rainbow trout juvenile were studied. There were 4 groups which were added with 0, 500, 1 000 and 1 500 mg/kg taurine individually, the trail were conducted for 12 weeks. The results showed that compared with group 1, body weight, body length and daily weight gain decreased in the 1 000 mg/kg taurine group on 12 week （P〈0.05）, FCR increased （P〈0.01） and body fat decreased in 1 500 mg/kg taurine group （P〈0.05）. On 4 week, SOD and T-AOC increased in 1 000 and 1 500 mg/kg taurine groups （P〈0.05）, but ACP decreased （P〈0.05）. MDA increased in 500 mg/kg taurine group （P〈0.05） and 1 500 mg/kg taurine group （P〈0.01）. AKP increased in the group which was added taurine （P〈0.05）. On 12 week, SOD decreased in 1 500 mg/kg taurine group （P〈0.05）, T-AOC decreased in 1 000 and 1 500 mg/kg taurine groups （P〈0.05）, MDA, AKP and ACP decreased （P〈0.05） in the group which was added taurine （P〈0.05）. In conclusion, the growth of juvenile rainbow trout were not improved by adding 500 〈 1 500 mg/kg taurine, immunity were increased on 4 week, but were decreased on 16 weeks.
