Genetic evaluation for some productive traits in Japanese quail by used Animal Model

Abstract

: The present study aimed to estimate Japanese quail's productive traits' genetic markers by used animal model. BW 0 , BW 2 , BW 4 and BW 6 were 9.32, 64.78, 142.23 and 213.50 gram respectively, while average daily increase. ADI 0-2, ADI 2-4 , ADI 4-6 and ADI 0-6 were 3.96, 5.53. 5.09 and 4.86 gram respectively. The additive genetic (σ 2 a), remainder (σ 2 e), phenotypic variances (σ 2 p) and heritability (h 2 ) are 10.4, 4.2, 14.6 and .71 for BW 0 while and they were 195, 96, 291 and .67 for BW 2. And 715, 432, 1147 and .62 for BW4 and 1950, 1500, 3450 and 0.57 for BW6 .The Minimum of breeding of BW 0, BW 2, BW 4 and BW6 were7.05 , 46.73, 119.21 and 192.66 while Maximum of breeding of BW 0, BW 2, BW 4 and BW 6 were 11.44, 79.41, 171.62 and 237.85. The minimum of breeding value of ADI 0-2, ADI 2-4, ADI 4-6 and ADI 0-6 were -0.832 , - 2.37, -1.35 and -0.338 while maximum of breeding value of ADI 0-2, ADI 2-4, ADI 4-6 and ADG 0-6 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.
