COMPARATIVE STUDY AMONG FOUR EGYPTIAN LOCAL STRAINS OF CHICKENS
Poultry Production Department, Faculty of Agriculture, Mansoura University
Abstract
This study was carried out to evaluate fertility, hatchability, growth performance, carcass traits and blood characteristics for four Egyptian local strains of chickens (Dokki-4, Gimmizah and Mamourah and Sinai). Eight hundred and four hatching eggs were used. Two hundred forty one-day-old chicks were used in growing exterminates. The obtained results show that Mamourah strain surpassed in egg weight, however, Mamourah and Gimmizah strains achieved highly hatched chick weights. There are no significant differences among the experimental strains in fertility or hatchability percentage. Mamourah and Gimmizah strains have significantly high body weight and weight gain without differences between them followed by Dokki-4 strain and Sinai breed without differences at seven weeks of age. The Sinai breed had significantly lower feed intake compared with the other strains during the total period of study. Mamourah strain has the best feed conversion ratio compared with the other birds. There are no differences among the tested strains in different carcass traits or serum blood characteristic. There are no differences in immunity parameters except for antibody titer against Avian Influenza Virus HI AI which Mamourah strain achieved high significant value comparing with Sinai breed. The results concluded that were no significant differences among Dokki-4, Gimmizah, Mamourah strains and the Sinai breed in fertility, hatchability, hatched chick weight, carcass traits and serum blood characteristics. Mamourah and Gimmizah strains achieved high body weight and weight gain followed by Dokki-4 strain and Sinai breed. Also, Sinai breed has lower feed intake, but Mamourah strain has the best feed conversion ratio throughout the first 7-weeks-old.
