A total number of 66 day old Japanese quail chicks divided into 2 treatment groups (33 in each treatment) with 3 replications in each having 11 birds (male, 5 and female, 6) were reared on floor and in cage system for a period of 5 weeks to know the effect of rearing system on growth performance and carcass characteristics. At the age of 35 days, average body weight and feed intake were 102.15 ...
