Effect of Oregano Essential Oil with Multi-Enzyme in Protein Reduced Diet on Broiler Performance
Journal of entomology and zoology studies(2019)
Abstract
The present study was conducted to evaluate effect of oregano essential oil with multi-enzyme in protein reduced diet in broilers. Randomly the day old broilers chicks were equally distributed into eight treatment groups. There were three replicates of 20 chicks each under each treatment. The control group (A) received with basal diet as per BIS (2007). Group B received diet with 2% reduction in Crude Protein (CP). Groups C and D received basal diet supplemented with oregano essential oil and with multi-enzyme @ 400g/tone, respectively. Group E received basal diet supplemented with oregano essential oil and multi-enzyme. Group F and G received diet with 2% reduction in CP supplemented with oregano essential oil and with multi-enzyme respectively. Group H received diet with 2% reduction in CP supplemented with oregano essential oil and multi-enzyme. The result showed that, broilers supplemented with oregano essential oil along with multi-enzyme alone or in combination recorded significantly higher (P<0.01) body weight. The feed intake was higher in all treatment groups. Furthermore, the feed conversion ratio was improved in all treatment groups. The lower mortality % was recorded in treatment groups. In conclusion, the broiler diet supplemented with oregano essential oil @ 200 mg/kg of feed along with multi-enzymes @ 400gm/tonne resulted higher body weight gain, improved FCR and reduced mortality.
