Effect of Addition Sinbiotic Isolate Pediococcus pentosaceus Strain N6 and Cassava Peel on Immunity Organs and Total Microbes in the Small Intestine of Super Native Chicken

Abstract

Factory feed is often added with antibiotics as a growth promoter. Giving synthetic antibiotics is very dangerous for health. This study aims to determine effect of addition synbiotic isolate Pediococcus pentosaceus strain N6 and cassava peel flour on the immune organs and total microbes in the small intestine of super native chickens. This research was conducted in Pancur Batu from September - December 2022. The design used was a completely randomized design (CRD) with 4 treatments 5 replicates so that 20 experimental units were obtained. The super native chicken used were 100 DOC. The treatments given were P0 (basal ration without sinbiotic), P1 (basal ration + sinbiotic 150 ml/kg ration), P2 (basal ration + sinbiotic 300 ml/kg ration), and P3 (basal ration + sinbiotic 450 ml/kg ration). Parameters studied were weight percentage of immune organs and total microbial colonies. The results of this study indicated that the addition of synbiotic isolate Pediococcus pentosaceus strain N6 and fermented cassava peel flour up to a dose of 450 ml/kg as an alternative feed for native chickens increased percentage weight of spleen, thymus, bursa fabrisius, and total microbial colony of super native chickens.
