Study on the Amino Acid Balance in Diet for Blunt-snout Bream Fingerlings

摘要

The experiments were conducted to study the influence of the amino acid balance in diet on the growth of blunt-snout bream (Megalobrama amblycephala Yih). The test diets with different proportion mixture of soybean, rape seed, cotton seed and fish meal, and with addition of free lysine and methionine were fed to the fingerlings. The weight gain, feed conversion and protein efficiency ratio were taken as the evaluation targets. The resuls showed that the growth of fingerlings were significantly varied between diets containing different proportion of animal protein and plant protein. The diet containing 15
