Genetic Parameters Of Bodyweight And Some Economic Important Traits In The Japanese Quail (Coturnix Coturnix Japonica)

📄 Project Abstract

This experiment was conducted to study the genetic estimates for body weight and some economic important traits in Japanese quail from a foundation stock of 784 chicks, which were sexed at day 21. Selected birds of 50 sires and 150 dams based on body weight were used as parents G0 (Unselected generations) for the next generation. Data were collected over two consecutive hatches for G1 ( selected generation one) and G2 ( selected generation two) and records collected at day 35, 42, 49 and 56 from males and females to determine the effect of selection on age and body weight at sexual maturity; the trend of growth in body weight, body length, egg quality characteristics, egg production, carcass traits in generations, sex and age of Japanese quail; the effect of sex and age on breast meat quality of Japanese quail; the rate of genetic improvement in reproductive traits, body weight, egg traits, carcass traits, mineral and chemical composition of meat in Japanese quail and the genetic param...
