Effects of jamu makarens in the ration on performance and the number of pathogenic microbes in the intestines of broiler chickens

Abstract

Research that aimed to examine the effect of jamu makarens in the rations on performance and intestines pathogenic microbes has been carried out for 35 days using 80 head broilers. A completly randomized design with four treatments and four replications was used in this study. The treatments were: Commercial rations without jamu makarens (A), Commercial rations + 2% jamu makarens (B), Commercial rations + 4% jamu makarens (C), and Commercial rations + 6% jamu makarens (D). The results showed that feed and water consumptions, feed convertion ratio (FCR) and pathogenic microbes in the intestines of broilers fed 2-6% jamu makarens lower than control (P<0.05), but final body weight and body weight gain not significantly affect. It was concluded that the administration of 2-6% jamu makarens in the rations could reduce feed consumption, drinking water, FCR and pathogenic bacteria in the intestines, but did not effect on final body weight and body weight gain.
