研究了非鱼粉日粮中结晶氨基酸补充水平的影响。非鱼粉饲料喂养虹鳟鱼20周后，虹鳟鱼的生长和饲料性能都很好，没有出现任何异常。在非鱼粉饲料中补充必需氨基酸（EAA）以平衡与对照鱼粉饲料相当的氨基酸谱，与对照鱼粉饲料组相比，没有进一步增强生长。试验鱼在不添加EAA的非鱼粉饲料中生长良好。结果显示，本研究所用的非鱼粉饲料中的必需氨基酸含量足以满足虹鳟鱼的必需氨基酸需求。
effect of supplemental levels of crystalline amino acids in the non-fish meal diets was investigated. Feeding of non-fish meal diets for 20 weeks produced excellent growth and feed performances for rainbow trout without any abnormalities. Supplementation of essential amino acids (EAA) in the non fish meal diets to balance amino acid profiles comparable to the control fish meal diets resulted in no fur ther enhancement of growth over the control fish meal diet group. The experimental fish could grow well on the non-fish meal diets without EAA supplement. This has shown that the content of EAA in the non-fish meal diets used in this study was sufficient to satisfy the EAA requirement of rainbow trout.
