Abstract
In a six week trial, 360 day-old Japanese quail chicks were fed on 12 experimental rations containing 4 levels of protein (20, 22, 24 and 26%) each with 3 levels of energy (2600, 2800 and 3000 k.cal. ME kg-I) and the data on feed consumption, weight gain, feed efficiency and muscle composition were recorded. The feed was offered ad libitum. Maximum weight gain (137.07 g) was observed in quails fed ration containing 26% protein with 2800 k.cal. ME kg-I energy. Minimum feed consumption and better feed efficiency was noted in birds fed 26% protein. Ten birds of either sex on each ration were picked up at random and slaughtered to determine muscle composition. Non-significant differences were found among the treatments in everting influence on weight gain, feed consumption, feed efficiency and muscle composition
