| Abstract | ||
| The present study aimed to estimate Japanese quail's productive traits' genetic markers by used animal model. BW0, BW2, BW4 and BW6 were 9.32, 64.78, 142.23 and 213.50 gram respectively, while average daily increase. ADI0-2, ADI2-4, ADI4-6 and ADI0-6 were 3.96, 5.53. 5.09 and 4.86 gram respectively. The additive genetic (σ2a), remainder (σ2e), phenotypic variances (σ2p) and heritability (h2) are 10.4, 4.2, 14.6 and .71 for BW0 while and they were 195, 96, 291 and .67 for BW2. And 715, 432, 1147 and .62 for BW4 and 1950, 1500, 3450 and 0.57 for BW6.The Minimum of breeding of BW0, BW2, BW4 and BW6 were7.05, 46.73, 119.21 and 192.66 while Maximum of breeding of BW0, BW2, BW4 and BW6 were 11.44, 79.41, 171.62 and 237.85. The minimum of breeding value of ADI0-2, ADI2-4, ADI4-6 and ADI0-6 were -0.832, -2.37, -1.35 and -0.338 while maximum of breeding value of ADI0-2, ADI2-4, ADI4-6 and ADG0-6 were 0.73, 1.356, 1.326 and 0.403.In the end, we notice the superiority of the resulting offspring in terms of their educational value of body weights over the generation of parents, and also superiority in the rate of daily gain increase. Therefore, it is recommended to use these offspring in basic clans for the selection of useful body weights and the rate of daily gain increase because it is one of the important productive characteristics and the establishment of a line for the production of meat. | ||
