Feed costs substantially affect the efficiency of poultry operations, justifying genetic improvement of feed utilization by selection. The current research was conducted to estimate genetic variance for the 4-wk feed conversion ratio (FCR) and its genetic correlations with BW, BW gain (WG), feed intake (FI), and residual feed intake (RFI) in Japanese quail. The data analyzed originated from a line selected for low FCR for 3 generations. In each generation, 35 sires and 70 dams were used as… CONTINUE READING
