Abstract
The current study conducted to evaluate effect of oregano essential
oil with multi-enzyme in protein reduced diet in broilers. The day old chicks
were equally distributed into eight treatment groups, randomly. 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 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. Broiler supplemented with oregano essential oil along with
multi-enzyme alone or in combination recorded significantly higher (P<0.01)
body weight. The increase in live weight in birds group E and H over control
was 8.45% and 3.56%, respectively. Likewise, the broilers in treatment groups
recorded significantly (P<0.01) higher gain in weights. The feed intake was
higher in all treatment groups. The feed conversion ratio was improved in all
treatment groups. The lower mortality % was recorded in treatment groups.
Treatments recorded significantly higher (P<0.05) ND titers. The carcass traits
did not show significant differences between treatments. The dietary
supplementation of oregano essential oil along with multi-enzyme alone or in
combination in basal or protein reduced diet was found to improve profit
margin in broiler production. In conclusion, the results of the present
experiment suggested that the dietary supplementation of oregano essential oil
along with multi-enzyme alone or in combination with basal or reduced
protein diet to improved growth performance, immune response and found to
be economically beneficial.
