Abstract
This experiment was conducted to determine the effect of 9 generations of divergent selection for 4 weeks Body Weight (BW4) on growth and reproductive traits in Japanese quail. For this purpose, HW and LW lines were subjected to individual selection for high and low 4 weeks BW, respectively and were compared with control line (C). In compare to LW line and except for average daily gain from 4-6 weeks, average daily gain for other periods was significantly higher in HW. Age of sexual maturity was 7 and 4 days more than control line in HW and LW, respectively (p≤0.05). Body weight of sexual maturity in HW was significantly higher than those in control (p≤0.05). In compared to the C line, total egg weight increased 18.57 g in HW and decreased 112.56 (g) in LW (p≤0.05). Total egg number in HW was significantly lower than those in C line (p≤0.05).
