Abstract This experiment was carried out at the Poultry Farm, Faculty of Agriculture, Minufiya University, Shebin El-Kom, Egypt. The experiment continued for four generations, (G0,G1, G2 and G3), through the hatching seasons 2010-2011 and 2011 - 2012. The aim of the experiment was to study the genetic improvement of some economic traits during the growth period in Quail population. Also, to increase body weight in different growth periods for increasing meat production in Quails, and at the same time, improving feed efficiency during growth period (28 – 56 days). The rate of selection response per generation for body weight at 8 wks were 17.5 (g / G). The rate of selection response for feed efficiency per generation was -0.12 g. In general this study obtained the possibility of directly improvement of body weight at 8 weeks of age and feed efficiency at (4- 8 wks) by using independent culling level in Quail populations. |
