Effect of Adding Medicinal Plant Extracts to The Broiler Diets on Productive Performance

Considering approaches to efficiently produce broiler, Therefore, this study was conducted to demonstrate the effect of adding some extracts to medicinal plants (Oleobiotec^®) in increasing the efficiency of production performance of broiler, for the period from 12 February to 18 March 2016. In this study, 192 chicks (Ross 308) one day old were randomly distributed to four treatments, each including three replicates of 16 birds, which were: Control group T1 (without addition) and the treatments T2, T3 and T4 which received extracts to medicinal plants(Oleobiotec^®)at concentrations 100, 150 and 200 mg/kg feed respectively. The results of this study indicated that the addition of Oleobiotec^® to the broiler diet, particularly T3 and T4 enhance the production performance of broiler especially in body weight and weight gain. Also, the results showed a significant improvement in the feed conversion ratio for T3 (150 mg Oleobiotec^®/kg feed). Also, the results revealed no significant effect in feed consumption rate in all treatments and for all periods except two week. Its was concluded from the results of this experiment that's adding different levels of Oleobiotec^® to the broiler diet enhance the productive traits of birds especially for the treatment T3 (150 mg Oleobiotec^®/kg feed).
