 Abstract:

  This study was conducted in the poultry farm of the Animal Production Department – College of Agriculture – Tikrit University from 2/27/2019 to 3/31/2020, To demonstrate the effect of the brown and gold color of plumage and generation in Japanese quail on some productive traits, two lines of Japanese quail with a brown plumage color line consisting of (15 males and 15 females) and line with golden plumage color consisting of (15 males and 15 females) and were raised in rooms with dimensions of 40 x 40 x 40 cm and numbered, and the birds were distributed randomly to the rooms in families and each family at a rate (1: 1) each generation. The results of the study showed significant differences in the effect of plumage color in the trait of the average number of eggs during 56 days of production, while there was no significant effect on average body weight at sexual maturity, the average age at sexual maturity, the average weight of the first egg and the average weight Eggs and average egg mass during 56 days of production. The third generation and parents were superior in the average body weight at sexual maturity and the third and second generation in the trait of age at sexual maturity as well as the third generation surpassed the parents in the trait of the average number of eggs produced during 56 days, while the third and second generation outperformed. And the parents over the first generation in the trait of the average egg mass during 56 days, as for the parents, they were significantly superior to the first and second generation in the average weight of the first egg and the average egg weight within 56 days, As for the overlap between the color of the plumage and the generation, the results showed significant superiority of the third generation with brown plumage color in the trait of the average body weight at sexual maturity and the average number of eggs produced within 56 days, while the third and second generation of brown and gold plumage color were superior in the trait of average age at sexual maturity. The third generation with brown plumage color and the parents of brown and gold plumage color were more than the average egg mass during 56 days, while the parents of brown plumage color significantly outperformed the average weight of the first egg, and the parents of golden plumage color were significantly higher in the average weight of eggs produced during 56 days. We conclude from this that the color of brown plumage was significantly superior to the average number of eggs. As for the generation and the overlap between them, they were significantly affected by the productive and reproductive traits.

Key words: plumage colour, generation, Japanese quail, production traits.
