摘  要：
研究了在豆粕型饲料中添加不同浓度的蛋氨酸对江黄颡鱼生长的影响。试验鱼分为3个组,蛋氨酸的添加量分别为0、0.2%、0.4%,分别对应Ⅰ、Ⅱ、Ⅲ组,Ⅰ组设为对照组,饲养周期为8周。试验结果表明,Ⅱ组、Ⅲ组的质量增长率显著高于对照组(P<0.05),其中Ⅱ组质量增长率最高(176.22±3.56)%;Ⅱ组的成活率显著高于对照组(P<0.05);各组的饲料系数与对照组比较无显著性差异(P>0.05),Ⅲ组饲料系数最小(2.60±0.13);各试验组之间的摄食量差异不显著(P>0.05),Ⅱ组的摄食量较对照组高12.50%。在本研究条件下,建议蛋氨酸的添加量为0.2%~0.4%。

摘  要：
An 8 week feeding experiment was conducted to evaluate the influence of supplementation of methionine(0,0.2%,and 0.4%)in soybean meal-based diets on growth of yellow catfish Pelteobagrus vachelli.There were significantly higher weight gain in the fish fed the diets containing 0.2%,and 0.4% of methionine than in the fish fed the diet containing 0% of methionine(P<0.05).The peak weight gain(176.22±3.56)% and significantly higher survival rate were observed in the fish fed the diets containing 0.2% of methionine(P<0.05).There were no significant differences in feed conversion ratio and food consumption(P>0.05)among the experimental groups.Between every groups,even though the fish fed the diet supplemented with 0.2% of methionine had 12.50% higher food consumption and lowest diet ratio in the contorl group(2.60±0.13).Therefore,under this condition,it is suggested that the optimal supplementation of methionine in the yellow catfish diets be 0.2%～0.4%.
