Abstract

In this study, the effects of feeds supplemented with DL-alanine and betaine on the growth and chemical composition of fingerling rainbow trout (Oncorhynchus mykiss) were investigated. Fish fed with DL-alanine (1.5% of diet) and betaine (1.5% of diet) supplemented diets had greater weight gains (35.36±1.81g and 38.47±3.02 g respectively) than those fed a control diet (28.32±0.31 g). It was found that the groups fed with attractant supplemented diets had better feed conversion and protein efficiency ratios than the control group. Whole body dry matter, fillet and whole body crude ash and crude protein ratios were similar in all the groups. The group fed a DL-alanine supplemented diet had a higher fillet dry matter ratio than the control group (p
