【摘要】 在基础饲料中分别添加牛磺酸1000、2000、3000mg/kg,L-肉碱100、200、300mg/kg,制成6种饲料,再以基础饲料作为对照组,共7种饲料饲养异育银鲫(Carassius auratus gibebio)8周。结果显示,各组的摄食率无显著差异,部分试验组饲料系数比对照组有显著下降,特定生长率有显著上升,其中牛磺酸1000mg/kg组和L-肉碱200mg/kg组的饲料利用及生长效果最佳。除超氧化物歧化酶外,过氧化氢酶和谷胱甘肽过氧化物酶活性、维生素E、氧化型和还原型谷胱甘肽含量等抗氧化指标均受到添加剂的显著影响,并且大多在牛磺酸1000mg/kg组和L-肉碱200mg/kg组变化最为显著。结果表明,生长性能的变化和抗氧化能力的变化密切相关。更多还原

【Abstract】 8-week growth trial was conducted to investigate the effect of taurine and L-carnitine on growth and antioxidant capacity of gibel carp(Carassais auratus gibebio).Taurine and L-carnitine had three additive levels individually(Taurine:1000,2000,3000mg/kg;L-carnitine:100,200,300mg/kg).The results showed that,food rate(FR)had no significant differenre,food coefficient rate(FCR)and special growth rate(SGR)was affected significantly by taurine and L-carnitine.Groups taurine(1000mg/kg)and L-carnitine(200mg/kg)had the significantly lowest FCR andhighest SGR.The activities of catalase and peroxidase and the contents of Vitamin E,reduced and oxidized L-glutathione were affected significantly by taurine and L-carnitine,and these indexes were the significantly lowest or highest for groups taurine(1000mg/kg)and L-carnitine(200mg/kg).The conclusion was that the growth performance is closely related to antioxidant capacity.更多还原
