Abstract: An experiment was designed using 4000 one-day-old chicks of four local chicken strains, namely Mandarah (MN), Gimmizah (GM), Silver Montazah (SM) and El-Salam (ES) to evaluate the productive and reproductive performance during and summer seasons. The main results could be summarized as follows:
- Body weight and growth rate at different ages were significantly affected by season, were better body weight and growth rate were obtained in winter season.
- Body weight and growth rate over the two seasons of ES and GM strains were higher than SM and MN strains at 8, 12 weeks of age and at sexual maturity.
- Chicks raised during winter season had better feed conversation from hatch to 12 weeks of age than those raised in summer season (3.85 vs 4.22).
- Highly significant differences among the average of feed conversation of four strains were observed; whereas GM, SM and ES strains had the best feed conversation during 4-8, 8-12 and 0-12 weeks of age.
- Egg number, egg weight, egg mass and feed conversation during the first 90 days of egg production were significantly better for hens raised through winter season than those raised during summer season.
- MN and SM strains recorded higher egg number and egg mass and better feed conversation during the first 90 days of egg production than GM and ES strains; while ES and GM strains produced heavier eggs than those of MN and SM strains.
- The hens raised during winter season had significantly higher fertility and hatchability percentage than those of summer season.
- MN strain had the highest fertility percentage (92.33%) followed by GM (91.31%) and SM strains (90.75%); while ES recorded the lowest percent (89.80%).
- MN strain was superior for hatchability (78.38%) followed by ES and GM strains (75.88 and 75.84%); while the lowest was recorded for SM
strain (74.43%).
- SM strain gave significantly the highest livability percent (96.29%) followed by MN and ES strains (95.10 and 93.90%); while GM strain recorded the lowest percent (91.74%).
- Generally, ES and GM strains recorded the superiority of body weight and growth rate; while MN and SM strains had good performance of egg
production
