The prolonged use of antibiotic has the potential to increase bacterial resistance and the level of drug residues in edible animal products. Alternatives to them, such as prebiotics, probiotics and other feed additives, has been studied. Thailand has many plants that were analyzed for the possibility as prebiotics and may be substituted for antibiotics use to improve broiler performance. This study was conducted to determine the effects of local plant extracts on broiler growth performance for use as substitute to antibiotic in the future. 2% of each shallot and tree onion extract was used in this experiment. The results found average daily gain (ADG), feed intake (FI) and feed conversion ration (FCR) of all trials were not significantly different (p0.05) but shallot and tree onion had higher ADG, FI and greater FCR with no significant difference when compared to antibiotic-fed group. It might be concluded as hypothesized that both shallot and tree onion extract might be substituted for the antibiotic use in broiler production.
