Aspire of the present study was to scrutinize the effects of Moringaoleiferaleaf extract (MOLE) on various growth biomarkers (feed intake,final live weight,weight gain and feed conversion ratio)of broiler chicks.A 6 weeks trials study was done on Day old broiler chicks (Hubbard) with 350 in number distributed into 5 equal groups. Group 1^st were named as Control group was fed on basal feed common to other groups and water without MOLE.The othertreatment groups MOLE₂, MOLE₄, MOLE₆ andMOLE₈ were provided with the basal feed with2, 4, 6 and 8mL ofMoringaoleiferaleaf extract per liter of their drinking water respectively.It was observed through the results that the broilers chicks provided with4% MOLEin watershowed significant (P<0.05) highestfinal and net body weight in comparison to control and other treatment groups. A significant (P<0.05) increased trend in live and dressed body weight was observed as compared to control group. As compared to control group, significant increased values of Hemoglobin and Packed cell volume were observed in broiler chicks fed on 2, 4,6, 8% of MOLE. Same trend was observed for white blood cells. However it was observed through the experiment that chicken of control group had lower counts of RBC and WBC, PCV and lymphocyte levels. It was concluded in the study that adding of 4% MOLE in drinking water caused an increase in growth performance and carcass traits. The broiler fed on feed with 4% Moringa showed highest performance compared to others .
