Potentially pathogenic commensal bacteria in the digestive tract of chickens can promote chicken discomfort leading ultimately to reduce economic efficiency and possible contamination of those carcasses. To influence the micro flora composition at this level, we used feed additive as pre/probiotics, acidifiers and herbal extracts. Analyses were performed by classical methods according to SR EN ISO 4833-2003 for the establishment of NTG, SR EN ISO 16649-2007 for the number of E. coli colonies, SR EN ISO 6549/AC/2006 to detect colonies from Salmonella spp. and SR EN ISO/TS 10272-2-2007 for isolation and confirmation of Campylobacter spp. colonies. The results of the chicken cecum micro flora from the experience showed very large values of variations depending on the feed additive used, the lowest values for NTG, the number of E. coli colonies Salmonella and Campylobacter spp. existence were found in the experimental group in which feed were used an feed additive based on plant extract.
