Egg 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 recorded. Egg production and hen day production (HDP) have also been calculated. Additionally, samples of 240 composite quail eggs, 60 eggs per line, have been randomly selected at the age of 88, 89, and 90 days. Those eggs were used to determine the quality of egg including egg weight, shell thickness, shell weight, shape index, air cavity, albumen index, yo lk index, Haugh unit (HU), and yolk color score. Furthermore, the data were analysed using general linear model (GLM) and Tukey’s test was p erformed to evaluate the pairwise differences among quails. The results showed that egg production traits were not different among lines, except age at first egg-laying (P < 0.0001). Moreover, brown plumage lines have higher egg weight, shell thickness, shell weight, shape index, yolk index, albumen index, HU, and yolk colour score than black plumage lines (P < 0.0001), on the other hand, egg air cavity of black plumage lines were higher than brown plumage lines, 1.71 versus 0.88 mm (P < 0.0001). It can be c oncluded that brown plumage line has better both exterior and interior qualities of egg than black plumage line. These findings may be useful to determine appropriate breeding program for laying quail in the future.
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 کامل
Effect of Dietary Betaine and Folic Acid Supplementation on Performance, Egg Folate Content and Egg Production of Japanese Quail
A study was conducted to investigate the effects of different betaine (BET) (0.0, 0.5 or 1.0 g/kg) and folic acid (FA) (0.0, 4.0 or 8.0 mg/kg) levels on performance, egg FA concentration and egg production of laying quails using 288 forty-two day-old Japanese quail in a 3 × 3 factorial arrangement of treatment based on randomized complete design. The results showed that none of the performance ...متن کامل

AIM The present study was conducted to evaluate the performance of gray, brown, and white varieties of Japanese quail (Coturnix coturnix japonica) with respect to body weight, egg production, and egg quality traits in the coastal climatic condition of Odisha. MATERIALS AND METHODS A total of 500-day-old straight run Japanese quail chicks of three varieties, viz., gray, brown, and white were r...متن کامل
Genetic Analysis of Egg Quality Traits in Bovan Nera Black Laying Hen under Sparse Egg Production Periods
The present research was designed to examine the genetic analysis of egg weight, egg yolk weight and egg albumen weight of Bovan Neva Black laying hens at 25, 51 and 72 weeks. For this purpose, thirty birds were selected from the layer flock in the Babcock University Teaching and Research Farm. They were individually housed in separate labeled battery cage. A total of thirty eggs were collected...متن کامل
Effect of Dietary Calcium Sources and Levels on Egg Production and Egg Shell Quality of Japanese Quail
The research was conducted at Bangladesh Agricultural University Poultry Farm, Mymensingh to evaluate the effect of different levels and sources of calcium on egg production and egg shell quality of Japanese quail (Coturnix coturnix japonica) up to 23 weeks of age. For that purpose a total number of 108 Japanese quails aged 20 week were fed on diets containing different levels (2.5%, 2.75% and ...متن کامل
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 کامل
