Abstract
This study aimed to evaluate the effects of strain, sex; different lighting and vaccination programs on broiler growth performance and carcass characteristics. One old day, two strains of broiler chicks were used (240 Evian-48 and 240 Arbour Acres), which were divided into male and female as sexed by feathered wings after they were selected at random. Under all conditions, each group was subjected to the same environmental factors and litter. Feeding and watering consumption ad libitum. The chicks were rearing under two different lighting (LP.1and 2) and vaccination (VP1and2) Programs too. The results showed significant improvement in body weight, feed intake and percentage of edible, and mortality in the Evian - 48compared to the Arbour Acres. Males are more likely to have a higher body weight than females. Also, males had the highest mortality percentage MP (11.5%) compared to females (9.5%). The lighting program2 LP2 and vaccination programs VP2 significantly enhancebody weight, edible, and mortality percentages. However, there were no significant differences in the feed conversion ratio (FCR) among strains, sex, lighting programs, and vaccination programs. Interaction groups (G) between different lighting and vaccination programs significantly (P<0.0001) impacted live body weight (BW), cumulative feed intake (CFI), feed conversion ratio (FCR), cumulative mortality percentage (MP), and the absolute and relative weight of edible parts.Especially Group-2 (light Program 2× vaccination Program 2), which gave the best production performance. *Conclusively,* this study obtained that the significant effects of strain, sex, different lighting, and vaccination programs on broiler growth performance and carcass characteristics. After this study, we are recommending to use the Evian- 48 strain with the lighting program2 LP2 and the vaccination program2 VP2 to give the best results in production performance under Egyptian environmental condition.
