abstract
The experiment was conducted to evaluate the effect of oregano essential oil with multi-enzyme in protein reduced diet on carcass traits and immune response in broilers. Randomly the four hundred and eighty day old chicks were equally distributed into eight treatment groups having three replicates of 20 chicks each. The control group (A) received with basal diet as per BIS (2007). Group B received diet with 2% reduction in 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 carcass characteristics such as dressing yield, eviscerated yield, giblet yield did not differ significantly among the various treatment groups but immune response was better in group supplemented with oregano essential oil as compared to other groups. It was concluded that oregano essential oil with multi-enzyme supplementation in basal or reduced protein diet has non-significant effect on various carcass characteristics but significantly improves immune response in broiler chicken.
