The Lempuyang Gajah [Zingiber Zerumbet (l.) Smith] Extract Supplementation in Broilers Feed to Suppress Foodborne Disease “Salmonellosis” for Consumers’ Health Safety Effort

The study aims to control Salmonellosis through the addition of Z. zerumbet extract in broilers feed. The experiment consisted of 5 treatments namely, T0 (standard diet), T1 (standard diet + infection of S. enteritidis), T2 (standard diet + infection of S. enteritidis + 0.33% Z.zerumbet extract), T3 (standard diet + infectionof S. enteritidis + 0.67% Z. zerumbet extract), andT4 (standard diet + infection of S. enteritidis + 1%Z.zerumbet extract). Each treatment was repeatedfive times. The parameters measured were thenumber of S. enteritidis colonies, small intestinalmorphology, and digestive enzymes activity. Theresults showed that no S. enteritidis colonies werefound in T3 and T4 treatments, whereas T2, T3and T4 had a high ratio of villi / Liberkuhn cryptdepth and higher enzyme activity as compared tothat of T1. It was concluded that the addition of Z.zerumbet extract at a concentration of 0.67% to1% has the potential as a feed additive forcontrolling Salmonellosis in broiler chickens.Thus, the extract can replace AGP as a feedadditive that is safe for the health of broilers aswell as humans as the consumers.
