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 کاملCharacteristics of egg parts, chemical composition and nutritive value of Japanese quail eggs--a review.
All nutrients including proteins, lipids, vitamins, minerals and growth factors required by the developing embryo, as well as a number of defense factors, can be found in avian eggs. Eggs are also a source of other substances with biological functions and activities inter alia immune proteins and enzymes. Although chicken egg consumption is currently at the highest level, eggs from other specie...
متن کاملEffect of EM on Growth, Egg Production and Waste Characteristics of Japanese Quail
A study was conducted to determine the effects of EM supplied in drinking water and feed on growth, egg production and waste characteristics of Japanese quail. The effect of EM on the growth of 1,000 day-old quail was assessed using a completely randomized design with four treatments: a control; EM added in drinking water at 1:5,000; EM (in the form of fermented compost or bokashi) added in fee...
متن کاملEvaluation of Genetic Diversity in Japanese and English White Quail Populations Using Microsatellite Markers
The Japanese and English White quails are widespread strains and belongs to the Galliformes order, Phasianidae family, Coturnix genus and Japonica species. These birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. In the current study, the genetic variation of Japanese and English White quail ...
