Abstract
This study was conducted to evaluate the effects of season (summer versus winter) at different ages on productive performance (body weight, feed consumption, mortality %, egg weight and egg production%) of Hubbard classic broiler breeder’s females during egg production period (25- 45 wks). The birds were fed according to the program feeding of producer company. The results revealed that there were significant differences in productive performance betweentwo seasons at different egg production periods. Body weight, feed consumption, egg weight and egg production% were significantly higher in winter than summer season. However, mortality rate was significantly lower in winter compared with summer season. Moreover, productive performance was significantly affected by season, breeder age and their interaction. It could be concluded that, there were significant differences in productive performance of broiler breeder chickens (Hubbard classic) under the two seasons (summer versus winter) at different egg production periods (25- 45 wks).
