Abstract
This study was conducted to evaluate body weights, average daily gain (ADG), relative growth rate (RGR), average egg weight, hen day egg production% (HDEP%), hen housed egg production% (HHEP%), age at sexual maturity, body weight at sexual maturity, fertil ity%, scientific and commercial hatchability percentage in a complete 2x2 diallel crossbreeding experiment [Fayoumi and Rhode Island Red (RIR)]. RIR showed significant (p ≤ 0.05) higher body weight, ADG, RGR, age at sexual maturity and body weight at sexua l maturity (1898.76 g, 9.04 g, 19 3.95%, 144.66 day and 1559.05 g, respectively) compared other genotypes. In addition , RIR recorded the highest egg weight, fertility percentage , scientific and commercial hatchability percentage (44.28 g, 85.59%, 94.91% an d 81.49%, respectively). While Fayoumi male×RIR female crossbred recorded the highest significant estimate for HDEP % and HHEP % (54.41 and 51.65%).
