The animals were assigned into five treatments using completely randomized design (CRD). The treatments were: T1-0% A.flava, T2-25% A. flava, T3-50% Α. flava, T4-50% A. flava, Ts-100% A. flava concentrations. Feed bought from a local miller was formulated with isocaloric and isonitrogenous. Samples of A.flava was subjected to plant identification and authentication prior to phytochemical analysis to determine the chemical composition. Growth performance, gastrointestinal histomorphology and cost and return analyses were evaluated. Finding showed that broilers supplemented with 25% A. flava had better final weight at 1581.72 g. gain in weight of 1353.06 g. and daily gain in weight. Feed conversion ratio (FCR) of animals supplemented with different concentrations of A. flava is not significant. Morphometric evaluation of 25% A. flava supplementation showed significant result in terms of duodenal villus number at day 20 and day 35 with. Duodenal villus height and cecal crypt depth showed significance with result difference at day 20, Duodenal crypt depth was significantly different in animals supplemented with 25% A flava at day 35. Supplementation with 25% A. flava had better profitability in cost to gain ratio and had the highest return above feed cost among treatments. Over all findings showed that the supplementation with 25% A. flava has positive effect on the growth performance, GIT histomorphology characteristics, and profitability in broilers. Further studies are recommended to elucidate the mechanism involved on the growth promoting effect of A. flava decoction in broilers.  aThesis (Master of Science - Animal Science)  aIncludes appendices and bibliographical references.
