Effect of using organic acids and enzymes on performance of Japanese quail fed optimal and sub- optimal energy and protein levels [electronic: 1. malic acid resource].

Includes reference.

An experiment was conducted to study the effectiveness of dietary malic acid supplementation as a growth promoter on Japanese quail performance, carcass characteristics, intestinal villi and pH, bacteria enumeration, blood parameters, 'digestibility coefficients and economical efficiency. A total number of 360 unsexed day-old Japanese quail chicks were equally divided into 4 groups of 6 replicates each. Two starter-grower corn-soybean meal (C-SBM) basal diets were formulated to contain 24 % CP & 2900 kcal ME /kg diet and 22 % CP & 2750 kcal ME /kg diet, respectively.
