| 中文摘要: |
| 设计4 种等氮等能的实用饲料，评价印度菜粕替代国产菜粕对奥尼罗非鱼生长和血清生理生化指标的影响。选取300 尾初始体质量为2.48（±0.05）g 的奥尼罗非鱼，随机分为4 组，G0 组为对照组（国产菜粕用量35），G50、G75 和G100 组为试验组，分别用印度菜粕替代对照组饲料中50%、75% 和100% 的国产菜粕，并添加0.1%的诱食剂DMPT，饲养8 周。结果表明，印度菜粕替代国产菜粕后，显著降低了罗非鱼幼鱼的生长性能，且随替代量的增加，影响程度加剧。印度菜粕替代国产菜粕对奥尼罗非鱼全鱼体常规成分和血清指标无显著影响。在奥尼罗非鱼幼鱼阶段印度菜粕替代国产菜粕比例不超过50%，即印度菜粕使用量在17.5%以下。 |
| 英文摘要: |
| A 8-week feeding trial with 4 practical diets at equal nitrogen and caloric basis was conducted to evaluate the effects
of China rapeseed meal replaced by Indian rapeseed meal on growth performance and plasma biochemical indexes of juvenile tilapia (Oreochromis niloticus ± O.aureus). A total of 300 fish with the initial body weight of 2.48 (±0.05) g were randomly divided into 4 groups, the group G0 was the control group (the amount of China rapeseed meal was 35%), while groups G50, G75 and G100 were trial groups fed with 50%, 75% and 100% Indian rapeseed meal replacing the China rapeseed meal, adding 0.1% feed attractant DMPT respectively. The results showed as follows: the growth performance of tilapia juveniles was decreased significantly and the impact aggravated with increasing the level of India rapeseed meal replace China rapeseed meal. There was no significant effects on body conventional components and serum indexes of the juvenile tilapia in the experiment of China rapeseed meal replaced by Indian rapeseed meal. The ratio of the India rapeseed meal in juvenile tilapia does not exceed 50%, means the usage of Indian rapeseed meal being under 17.5%. |
