Abstract
The current experiment was carried out to compare REML-based to ANOVA-based methods in estimation of crossbreeding genetic parameters in chicken experiments. The current experiment involved a full 4*4 diallel crossing among four Egyptian breeds (Alexandria (AA), Fayoumi (FF), Matrouh (MM) and Golden Montazah (GG). The studied traits were body weight at hatch (BWH), body weight at 4 weeks of age (BW4), body weight at 8 weeks of age (BW8) and body weight at 12 weeks of age (BW12). The general comparison among models showed the superiority of REML-based method, especially in prediction ability with significant difference (P
