The study was conducted to find out the effect of some feed additives in reducing the infection rate of broilers with Salmonella typhimurium. Forty broiler chicks at one week of age were divided into 4 treatments, 10 chicks each as follows: T1: uninfected control. T2: Salmonella typhimurium infected + Iraqi Probiotic. T3: Salmonella typhimurium infected + Poultrygrow 250. T4: Salmonella typhimurium infected only. One day after feeding on feed additives, the birds were experimentally infected with Salmonella typhimurium through the mouth. Results show that Iraqi probiotic did not decrease the severity of infection with Salmonella typhimurium in comparison with those of Poultrygrow 250, shown by the percentage of mortality and number of Salmonella excreted with the feaces. Poultrygrow 250 causes a significant (ρ < 0.01) increase in body weight, weight gain and feed conversion ratio through reducing feed consumption. Iraqi probiotic has similar effect but for less extent. It was conducted that adding Poultrygrow 250 to the feed decreases the intensity of Salmonella typhimurium infection in broiler and improves performance.
