Effect of Different Feed Restriction Regimes on Growth Performance and Economic Efficiency of Japanese Quails
نویسندگان
چکیده
The present study was executed to examine the growth performance and economic efficiency of Japanese quail (Coturnix coturnix japonica) at Avian Research and Training (ART) Centre, UVAS, Lahore. For this purpose a total of 3200 quail chicks were allocated to four different feed restriction regimes comprising four close-bred stocks (Imported, Local-1, Local -2 and Local-3) at the age of 10 days. The experimental quails in group 1 were fed ad-libitum (20.30% CP, 1.3% Lysine) diet throughout the experimental period to serve as control while groups 2, 3 and 4 were provided with 1 hour feed3-hour off, 2-hour feed2hour off and 3-hour feed-1hour off feeding regimes, respectively. Weekly data on growth parameters were recorded. Maximum feed intake was observed in ad-libitum fed group whereas the highest body weight gain was observed in ad-libitum and 3 hour fed quails. The best FCR leading to maximum profit margin was observed in 3 hour-fed group. However, different close-bred stocks could not express any significant difference in growth parameters.
