Abstract: The study was conducted to determine effect of egg-weight on hatchability and subsequent growth performance of Fayoumi breeds. A total of 576 eggs were purposively selected and arranged into three groups of small, medium and large sizes each with 192 eggs. Each egg group was randomly sub-divided into three replicates of 64 eggs in a CRD. Eggs were incubated for 21 days and chicks hatched on the same day were counted and individually weighed. Chicks were intensively raised on deep litter system for eight weeks on same diet, but kept separately according to their initial treatment of eggs. Data was analyzed by GLM of SAS and separated for means by Duncan’s multiple-range test. The study result revealed that egg size had effect on hatchability and strongly influenced all parameters measured during the brooding periods. It has significant effect on day-old weight, body weight, final weight gain, final feed conversion and mortality. Chicken producers may opt for medium-sized eggs principally for the purpose of better hatchability and feed conversion ratio whereas large sized eggs for better hatchling weight, weight gain and survivability. It is also recommended that future work may also address the effect of egg size on the same parameters at grower or pullet stage performance and specific diseases which cause paramount chick mortality should be identified.
