Interpretive Summary: The bacterial population found in the gastrointestinal tract of broiler chickens consists of many species of bacteria and can vary from bird to bird. In order to control food poisoning bacteria in chickens and improve gut health, many different dietary amendments such as prebiotics, and organic acids such as vinegar have been utilized. In this study, we evaluated the effect of sodium bisulfate on bacteria changes in the gastrointestinal tract of broiler chickens over time using an approach that can identify different types of bacteria during one test. The results of the test found that changes in the bacteria populations occurred when the birds were fed a dietary amendment.
Technical Abstract: The gastrointestinal microbial community in broiler chicken consists of many different species of bacteria and the overall microbiota can be various from bird to bird. In order to control pathogenic bacteria in broiler and improve gut health, numerous potential dietary amendments such as prebiotics and organic acids have been utilized. In this study, we evaluated the effect of sodium bisulfate on microbiota shifts on crop, cecum, and ileum of broiler chickens over time using a pyrosequencing platform. The diversity information in each digestive organ sample exhibited considerable variation and can be clearly separable from each other, suggesting distinct bacterial populations. Although there is no apparent microbial cluster between control and treatments, we identified the shifts of overall microbiota in crop, ileum, and cecum as well as changes in specific microorganisms such as Bacteroides, Clostridium, and Lactobacillus species over time.
