Commercialization of chicken farming and improvement of production efficiency has led to be the adoption of a range of additives as growth promoter. Antibiotic-based growth promoter have long been utilizing as animal feed additives. Wide spread usage of these substances has resulted in an escalation of antibiotic resistance and the accumulation of antibiotic residues in animal product. Because of these weaknesses there is rising interest in employing natural growth promoters. Therefore, this study has conducted on the effects of different garlic extract levels inclusion on the growth performance and carcass characteristic of broiler. The experiment was arranged in a completely randomized design (CRD) with four treatments, each replicated three times with 15 birds each. 180 chicks with similar body weight were used for this trial and were randomly distributed to the four treatments. They were T1 (NC, basal diet and drinking water), T2 (PC, basal diet + drinking water with oxtetracycline (0.2 g/ 10 litter), T3 (basal diet + drinking water (1.5% GEX)) and T4 (basal diet + drinking water (3% GEX). During the trial periods daily feed intake and weekly body weight were recorded and carcass evaluation was made. The result obtained that, the body weight gain and feed conversion ratio of birds were significantly (P<0.05) improved by 1.5 and 3% GEX inclusion levels. Most of carcass trait such that slaughter, dressing, breast, liver and GIT weight were highly (P< 0.05) affected by 1.5 and 3% GEX inclusion levels. Reduced abdominal fat weight and percentage (P< 0.05) was recorded in GEX inclusion levels. Generally, based on the results of the current study garlic extract at 1.5 and 3% inclusion levels in drinking water should be considered as potential growth promoters that may replace the antibiotic in broiler farm.
