Dissertation note: Thesis (M.Sc.) - Cairo University - Institute of African Research and Studies - Department of Natural Resources Summary: A total of 1680 eggs were used to investigate the effect of egg storage time (EST) on egg quality, hatchability and chick quality traits of hubbard (HU), Cairo B2 (B2) and Fayoumi (FA) broiler breeders (48 wk of age). The HU are commercial broiler breeders, B2 is a new Egyptian broiler cross-line between Arbor Acres males and Egyptian native white baladi females in the 8 thgeneration and FA is an Egyptian native breed. There were 12 groups (4 replicates per group) arranged factorially with 3 broiler breeders (HU, B2 and FA) and 4 ESTs (0, 3, 7 and 10 day). Fertility rates were 94.6, 89.2, and 84.8% for HU, B2, and FA, respectively. No interaction effects were detected for all traits except for haugh units that were of HU{u00B4}s eggs in between FA's eggs values (the highest) and B2's eggs values (the lowest) for all ESTs except for 10 day that, the values decreased faster in HU{u00B4}s eggs than other breeders' ones. Results indicated that HU fresh egg and chick weights (71.8 and 46.6 g) were higher than FA (52.1 and 33.4 g) and B2 (67.1 and 43.4 g) were intermediate, respectively (P<0.0001). The same trend was observed in hatchability (88.5 vs. 82.3 vs. 74.2%) for HU, B2 and FA, respectively

A total of 1680 eggs were used to investigate the effect of egg storage time (EST) on egg quality, hatchability and chick quality traits of hubbard (HU), Cairo B2 (B2) and Fayoumi (FA) broiler breeders (48 wk of age). The HU are commercial broiler breeders, B2 is a new Egyptian broiler cross-line between Arbor Acres males and Egyptian native white baladi females in the 8 thgeneration and FA is an Egyptian native breed.
