A day-old broiler chicks with total number of two hundred and four (204) (Ross 308) were randomly allotted to eight (8) dietary treatments with four (4) replicate pens per treatment (average of 6 birds per replicate pen). Chicks in each treatment were allowed ad libitum access to their diet and water for thirty five (35) days. Dietary supplement for the 35 days were: Corn-soyabean meal basal diet (control); control +0.01% antibiotics; control +0.1% probiotics; control +0.02% prebiotics; control +0.06% essential oil; control +0.6% organic acid; control +0.1% enzyme and control + all the additives in the treatment groups (mixture). Growth performance results showed that there was significant increase (p}, journal = {American Journal of Applied Sciences}, publisher = {Science Publications} }
