Effect of using different levels of Ajwain extract as growth promoters in comparison with virginiamycine antibiotic on performance, carcass characteristics, and some blood parameters of Cobb 500 broiler chicks

چکیده مقاله

This study was designed to investigate the effect of ajwain extract in comparison with virginiamycine on performance of broiler chicks. A total 360 one day broiler chicks were randomly divided into 4 treatments. Each treatment was further divided into 6 replicates. Chicks were fed a basal diet as control group, basal diet with 0.02% - 0.04% ajwain extract and with 0.02% virginiamycine powder. At the end of trial (42 days), four birds form each treatment were weighted and slaughtered. Some blood parameters were investigated at 42 days. Data showed that FI increased significantly in 0.04% ajwain extract and 0.02% virginiamycine in comparison to others (P<0.05). Body weight gain and total body weight were also significantly higher in treated groups. Triglyceride and cholesterol level decreased significantly in ajwain extract groups. LDL level decreased significantly and HDL levels increased in all of the treated groups. Data showed that Intestinal microbial population changed positively by using ajwain and virginiamycine. In conclusion we could demonstrate that use of ajwain extract at the present levels enhanced FCR, changed some blood parameters and beneficial effects in intestinal microbial population on broiler chicks.
