Egg Quality of Different Chicken Genotypes in Summer and Winter

M. A. Islam, S. M. Bulbul, G. Seeland and A. B. M. M. Islam

ABSTRACT

External and internal quality of 54 fresh eggs from Desi full feathered (d), Desi naked neck (n) and Shaver redbro ( r ) in summer and winter were tested to compare the genotypes, and to select the genotype for better reproductive fitness. Egg quality traits; egg colour, yolk width, yolk weight and albumen dry matter weight tended to increase in winter in comparison with summer. But, eggs contained significantly higher albumen width and height, yolk height, egg shell weight and thickness, dry matter weight and per cent of yolk in winter than in summer. The genotypes differed significantly for egg quality traits except, egg shell thickness, dry matter per cent of albumen and yolk. The thickest egg shell was observed in desi naked neck. Redbro was the best for egg quality traits. However, Desi naked neck strain produced better quality eggs than that of indigenous full feathered birds.
