Effect of supplementation different levels of plant extract mixture to thediets of broiler on performance

This research; This study was carried out to determine the effect of herbal extract mixture added to mixed feeds at different rates on the performance, internal organ weights and carcass characteristics of broiler animals. 144 Ross 308 day old male broiler chicks were used in the study. It was divided into control and three experimental groups, each with 36 items. Herbal extract mixture at the levels of 0, 20, 40, 60 mg/kg was used in the mixed feeds made according to the periods. The trial lasted 35 days. During the trial, no statistical effect was observed in adding different levels of herbal extract mixture to broiler rations in terms of live weight, live weight gain, internal organ weights and carcass characteristics according to periods. The difference between the periodic average values in the feed consumption and feed conversion rate of the herbal extract mixture used in the study was found to be statistically significant (p <0.05). As a result, using different levels of herbal extract mixture in broiler compound feeds has a significant effect on performance.
