Abstract
The experiment was conducted to study the effects of dietary supplementation of various levels of thyme and peppermint essential oils as an alternative to antibiotic growth promoter on performance of commercial broilers. Two hundred and fifty six (256) straight run day old commercial broiler chicks were distributed randomly to eight experimental treatments, consisting of 32 chicks in each treatment. Each treatment consisted of four replicates with eight chicks per replicate. The experiment was conducted for a period of six weeks. The eight treatments were divided as follows: T1 diet (control with no antibiotic and no essential oils), T2 diet with bacitracin methylene disalicylate (BMD) @ 50g/100 kg feed, T3 diet with thyme essential oil @ 15g/100 kg feed, T4 diet with thyme essential oil @ 20g/100 kg feed, T5 diet with thyme essential oil @ 25g/100 kg feed, T6 diet with peppermint essential oil @ 20g/100 kg feed, T7 diet with peppermint essential oil @ 25g/100 kg feed and T8 ration with peppermint essential oil @ 30g/100 kg feed.
