| Abstract | ||||
| Aiming to evaluate the productive performance of some commonly found in Egypt broiler breeders’ strains (i.e. Arbor Acres, Hubbard, Indian River, Cobb 500 and Ross 308), the current study was carried out at some commercial farms in three different governorates (North Sinai, Ismailia and Fayoum) during the period from 2015 to 2019. Records of 99455 broiler parent females (23440, 18800, 20623, 12480 and 24112 females) from Arbor Acres, Hubbard, Indian River, Cobb 500 and Ross 308 broiler breeders, respectively, were collected and used in the present study. All studied strains reared under close house conditions according to their management guides from breeding companies. Results showed that, body weight at receiving time for different strains ranged between 32.56 g (Hubbard) to 42.42 g (Arbor Acres). Arbor acers pullets reached 2092.5 g body weight at sixteenth week of age, while the lightest weight at this age detected for Indian River pullets (1683.0 g). After photo-stimulation, reaching sexual maturity, Hubbard pullets recorded the heavier body weight as 3032.25 g comparing with 2954.48, 2919.67, 2861.75 and 2822.5 g for Ross, Cobb, Indian River and Arbor Acers broiler breeder pullets, respectively. Statistical analysis revealed highly significant (P≤0.01) differences between strains at receiving time and 24 weeks of age. Results revealed that, daily and cumulative feed consumption differed significantly (P≤0.01) at first week of age among studied strains, however, the differences in daily and cumulative feed consumption were not significant at 24 weeks of age. Current results could help to predict and evaluate the performance of breeders during production cycle. | ||||
