| dc.description.abstract | The present study was conducted on two purebreds, namely Vanaraja (dual purpose type) and Gramapriya (the layer type) chicken and their crosses maintained at Institutional livestock farm complex , Bihar veterinary college Patna-14 on random mating. The genetic group taken were as Pure breds Crossbreds 1. GP♂♂ x GP♀♀ 3. GP♂♂ x VR ♀♀ 2. VR♂♂ x VR♀♀ 4. VR ♂♂ x GP ♀♀ Six males and 30 females were taken from each genetic group and maintained separately under deep litter system with a mating ratio of 1 male : 5 females. To study the genetic effect on egg quality traits a total of more than 50 eggs were collected at random from each of 4 genetic groups upto 28 weeks of age. Irrespective of genetic groups, all these eggs were divided into 4 different groups with a difference of 5g from each to observe the effect of egg weight on egg quality traits. To study the genetic effect on ASM, egg weight at the age of sexual maturity (ASM) and body weight at ASM, fertility and hatchability percentage. To find out the heterosis for all the egg quality traits and for hatchability and fertility. | en_US |
