| 摘 要： | 鲈鱼的生长受饲料中组氨酸(His)的含量变化显著(P<0.05)。当饲料中组氨酸含量过低或过高时,鲈鱼的终末体质量和特定生长率显著低于其它处理组,而处理组2(组氨酸含量为0.45%)、处理组3(组氨酸含量为0.57%)和处理组4(组氨酸含量为0.66%)之间差异不显著。终末体重、特定生长率和饲料效率在处理组3(组氨酸含量为0.57%)达到最大值,分别为21.0 g,1.72%d-1和0.81。以上结果表明,His是鲈鱼生长的必需氨基酸之一,且鲈鱼能有效利用晶体His。根据饲料中组氨酸的含量与鲈鱼特定生长的关系,经计算求得鲈鱼饲料中组氨酸含量为0.54%饲料干物质(即1.29%蛋白)时,鲈鱼的生长达到最佳状态。

| Abstract: | Dietary histidine significantly affected the growth responses of Japanes seabass(P<0.05).FW and SGR of fish fed diets less or beyond the optimum requirement level for histidine were significantly lower compared to other treatments.However,there were no significant differences among diet 2(0.45% His),diet 3(0.57% His),diet 4(0.66% His) and diet 5(0.78% His).FW(21.0 g),SGR(1.72% d-1) and FE(0.81) were the highest in fish fed diet with 0.57% His(Diet 3).The results indicated that for growth of Japanese seabass... |
