| 摘 要： | 在饲料中添加0、200、400、600、800、1000、1400、1800mg/kg的牛磺酸,饲养草鱼种30d,研究牛磺酸对草鱼的生长效应。结果表明:①牛磺酸促进草鱼生长(除1800mg/kg添加量外)。添加量为600mg/kg时,特定生长率(SGR)、饲料转化率(FCR)和蛋白质效率表现为最好;②饲料中添加牛磺酸后,草鱼体水分含量下降,体脂增加,体蛋白含量增加,灰分含量、内脏/体重比、肥满度各试验组之间差异不显著。根据生产性能指标综合评定,我们建议草鱼饲料中牛磺酸最适添加量为600mg/kg。

| Abstract: | The experiment studied the effects of taurine on growth of grass carp , by supplying different levels of taurine, including 0,200,400,600,800,1 000,1 400,1 800mg/kg, to the diets .The results showed that:①In additional to dietary taurine level of 1 800mg/kg, growth performance of grass carp were remarkably increased. At 600mg/kg level, specific growth rate(SGR)?protein efficiency ratio(PER)were improved significantly, and it had a lowest feed conversion ratio(FCR), which means a highest feed efficiency; ② Protein and fat of grass carp were improved and moisture of it was decreased after taurine were supplied in diets, and there was no significant difference in ash , purtenance/whole-body ratio and fullness of grass carp among and within experimental groups. On base of synthetical index of growth performance,we suggested that the optimum additive level of taurine was 600mg/kg in diets of grass carp. |
