The present study was conducted to examine the growth performance and economic efficiency involving 3200, 10-days old Japanese quail chicks (Coturnixcoturnix Japonica). Comparative performance of four close bred stocks (Major- Imported, Kaleem- Local-1, Sadaat- Local -2 and Zahid- Local-3) allocated to four different feed restriction regimes were studied. The chicks were fed ad-libitum for the first 10 days and then subjected to a 28 days experimental trial. Each treatment was replicated five times. The birds in 1st group were fed ad-libitum throughout the experimental period, while, those in group 2nd were provided 1 hour feeding and 3-hours off. Those in groups 3rd and 4th were allotted 2-hours feeding and 2- hours off and 3-hours feeding and 1- hour off, respectively. All the experimental birds were provided the same quail starter feed containing 20.30 percent crude protein with 1.3 percent lysine level throughout the experimental period. At 2nd week of experiment sexing was practiced with in the treatment, male and female birds were sexed separately by individually observing their breast color. Weekly data on growth performance parameters were recorded and analyzed using ANOVA technique under Completely Randomized Design in factorial arrangement. The comparison of means was made using DMR test. Significantly more feed intake and folds of increase in body weight were observed in female broiler quails than those of males. Maximum feed intake was observed in ad-libitum group followed by 4th (3hrs-feed-1hr-off), 3rd (2hrs-feed-2hrs-off) and 2nd (1hrs-feed-3hr-off) group. Body weight gain expressed none-significant difference among treatments. Best FCR leading to maximum profit margin was observed in 2nd group with 1hr-feed-3hrs-off. However, close bred stocks did not show any significant difference on growth parameters.
