Duodenum Histomorphology and Performance as Influenced by Dietary Suplementation of Turmeric (Curcuma longa), Garlic (Allium sativum) and its Combinations as a Feed Additives in Broilers

Abstract. This research was conducted to evaluate the effect of turmeric water extract, garlic and combination turmeric and garlic as a feed additive in the broiler diet on performance, and duodenum histomorphology. Affectivity of treatments was assessed by addition of phytobiotic (control, 015% zinc bacitracin, 2.5% TE, 2.0% GE, 2.5% TGE) which were arranged in a Completely Randomized Design with 4 replications. The variables measured were duodenum histomorphology (villi height, villi surface area, crypt depth, rasio villi height to crypt depth) and performances (body weight gain, feed intake, FCR). Results showed that diet with 2.5% TE, 2.0% GE and 2.5% TGE increase significantly (P<0.01) on duodenum histomorphology compared to positive control and negative control. The highest villi height was attained by feeding 2.5% TGE (1726.67 ???m) and villi surface area (5054.17 ???m2) and the lowest was attained when feeding positive control 1005 ???m and 1395.66 ???m2. No significant different (P>0.05), were observed in body weight gain and FCR beetwen different treatments, but the negative control feed intake increased significantly (P
