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

Abstract: This research was conducted to evaluate the effect of turmeric water extract, garlic and combination of 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, ratio villi height to crypt depth) and performances (body weight gain, feed intake, FCR). Results showed that diet with 2.5% of TE, 2.0% of GE and 2.5% of TGE significantly increased (p<0.01) the duodenum histomorphology as compared to positive control and negative control. The highest villi height was attained by feeding 2.5% TGE (1726.67 μm) and villi surface area (5054.17 μm2.) and the lowest was attained by feeding positive control 1005 μm and 1395.66 μm2.No significant differences (P > 0.05), were observed in body weight gain and FCR beetwen different treatments, but the negative control feed intake increased significantly (P < 0.05), compared to the positive control. The research concluded that the incorporation of 2.5% TE, 2% GE and combined 2.5% TGE as feed additive enhanced duodenum histomorphology without no side effects on performances in broiler chicks.
