Abstract
The present study was done to determine the effects of selection, for twelve generations for increased 6-week body weight, on the body weight and carcass characteristics of Cairo B-2 line in comparison with the Random Breed Control line. (RBC). The result indicated that Cairo B-2 line was significantly heavier 35.4% for males and 33.2% for females than RBC line. The slaughter trial indicated that Cairo B-2 line had significantly higher carcass, breast meat, leg meat, and wings with bones weights than RBC line at 6 weeks of age. Males, of both lines, had significantly higher carcass, breast meat, leg meat, and wings with bones weights compared to the females. The phenotypic correlations between LBW at 6 weeks of age and all other traits studied in comparison to RBC line, for 11generation. Also sixteen microsatellite markers, related to body weights and carcass part weights were investigated. The average number of alleles for these sixteen microsatellite loci for Cairo B-2 was 9.5 compared to 8.1 alleles for RBC line. The average heterozygosity value for the microsatellite loci were 0.726 ranging across loci from 0.620 to 0.820 for Cairo B-2 line. The average heterozygosity was 0.743 ranging between 0.625 and 0.815 for RBC line
