    Genetic Influence On Some Reproductive And Egg Quality Traits Of Vanaraja And Its Crosses With Desi Chicken Of Bihar
    (Department of Master of Veterinary Science (Animal Genetics and Breeding), BAU, Sabour, 2016-07) Yashveer, Vinita; Mandal, K. G.
    The present study was conducted on Vanaraja and its crosses with Desi chicken native to South and North Gangetic plane of Bihar. Vanaraja was maintained in the Instruction Livestock Farm Complex (ILFC), Bihar Veterinary College, Patna on random mating. Male birds of Desi chicken were brought into the farm from different districts of Bihar for crossing with the females of Vanaraja.

    The present experiment was conducted on four genetic groups of poultry involving Vanaraja (VR) and Gramapriya (GP) breeds maintained at instructional livestock farm of Bihar Veterinary College, Patna -14 on random mating for a large number of generations. The four genetic groups were formed in the following manner given below: 1. VR♂♂ x VR ♀♀ 2. GP♂♂ x GP ♀♀ 3. VR♂♂ x GP ♀♀ 4. GP♂♂ x VR ♀♀ The data were obtained collected on 300 birds of which 120 and 180 were males and females respectively. The number of male and female birds in each genetic group were taken as 30 and 45 respectively. Besides, 6 males and 6 females from each genetic group were taken randomly at 20 weeks of age to study various carcass traits. The traits measured in the present experiment were as follow: A. Body weight traits 1. Zero day body weight (g) 2. 5 – week body weight (g) 3. 10 – week body weight (g) 4. 15 – week body weight (g) 5. 20 – week body weight (g) B. 20 - week carcass traits 1. Dressed weight (g) 2. Eviscerated weight (g) 3. Giblets weight (g) 4. Legs weight (g) 5. Thighs weight (g) 6. Breast weight (g) Besides, dressing %, evisceration %, giblets %, Legs %, thighs % and breast % were also studied on the basis of pre-slaughter starved weight.

    Genetic impact on some of the reproductive and egg quality traits of Vanaraja and Gramapriya birds and their crosses
    (Department of Animal Genetics and Breeding, BAU, Sabour, 2015) Sinha, Beena
    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.
