Abstract: A total number of two hundred broilers of mixed sexes comprising of one hundred Ross and one hundred Anak broiler strains was assessed for body weight (BWT), body girth (BDG), keel length (KLL) and shank length (SHL) from day-old to 9 weeks of age. Differences in BWT, BDG, KLL and SHL between the two genotypes were significant (p<0.05) at all ages except BWT at 3 weeks, BDG at 6 weeks and SHL at 9 weeks of age. Significant sexual dimorphism existed between both sexes and genotypes. Male broilers were also superior to the females in all growth traits in the Ross genotype whereas Anak genotype only exhibited superiority of the males over the females in BWT at 9 weeks, BDG at 6 and 9 weeks and SHL at 9 weeks of age. The Ross broiler strain was significantly (p<0.05) heavier than the Anak broiler at 6 and 9 weeks of age. This difference in weight is an indication, therefore that genetic difference existed in growth rates between the two commercial strains studied. This could form reliable bases for further studies and effective selection for meat yield between Ross and Anak broiler for further improvement.
