genetic analysis of egg quality traits in japanese quail
the present research was conducted to analyze the genetic structure of egg quality traits in japanese quail. external and internal egg quality traits were assessed on 1706 eggs of laying japanese quail. eggs were collected for 4 days at the quaits 10 weeks of age. the investigated traits were analyzed through univariate as well as multivariate animal models employing restricted maximum likeliho...
متن کاملEgg Production Traits and Egg Quality Characteristics in Black and Brown Plumage Color Lines of Japanese Quail
The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...
متن کاملGenetic Polymorphism in Prolactin Gene and its Association with Reproductive Traits in Japanese Quail (Coturnix japonica)
The present study was carried out to investigate the polymorphism of intron 3 to exon 3 of prolactin gene containing 24 bpindel at nucleotide position (np) 358 and its association with some reproductive traits in Japanese quail. These traits consisted of weight (WSM) and age at sexual maturity (ASM), mean egg weight at 2nd, 4th, 6th, and 2-6th weeks (MEW), and the number of eggs during the 2...
متن کاملEvaluation of Reproductive traits in three strains of Japanese Quail
A study was undertaken to evaluate the reproductive performance in two plumage colour variant strains of quail, viz; Brown, White Breasted and a dark Cinnamon Brown (commercial) strain. A total of 694 straight run active chicks were obtained in three hatches at weekly intervals from the three strains. Sex was determined at six weeks of age and female progenies were separated and data on reprodu...
