Abstract

This research was carried out to determine the genetic parameters for some production traits. The overall least-squares means for body weights at day-old, 2nd and 4th week of age were 7.94, 59.20 and 141.64 g, respectively and average daily gains (ADGs) during 0-2, 2-4, 4-6, 6-8, 8-10 and 10-14 weeks of age were 3.66, 5.89, 3.69, 2.72, 1.51 and 0.46 g, respectively. Hatches, sexes and strains had significant effect on body weight and ADGs. The females were significantly heavier than the males. The heritability estimates for the body weights varied from low to high in Black, medium to high in Brown and low to medium magnitude in Black random bred, while these estimates for ADGs were low or moderate to high in magnitude.
