The gastrointestinal microbial community in broiler chickens consists of many different species of bacteria, and the overall microbiota can vary from bird to bird. To control pathogenic bacteria in broilers and improve gut health, numerous potential dietary amendments have been used. In this study, we used a pyrosequencing platform to evaluate the effect of sodium bisulfate on microbiota of the crop, cecum, and ileum of broiler chickens grown over several weeks. The diversity information in each digestive organ sample exhibited considerable variation and was clearly separable, suggesting distinct bacterial populations. Although no apparent microbial clustering occurred between the control and the dietary treatments, we did observe shifts in overall microbiota populations in the crop, ileum, and ceca as well as changes in specific microorganisms such as Bacteroides, Clostridium, and Lactobacillus species that were identified as birds became older.
肉鸡的胃肠道微生物群落由许多不同种类的细菌组成，而且总体微生物群在不同个体之间可能存在差异。为了控制肉鸡中的病原菌并改善肠道健康，人们使用了许多潜在的日粮添加剂。在本研究中，我们使用焦磷酸测序平台评估了硫酸氢钠对生长数周的肉鸡嗉囊、盲肠和回肠微生物群的影响。每个消化器官样本中的多样性信息表现出相当大的差异，并且明显可区分，这表明存在不同的细菌种群。虽然在对照组和日粮处理组之间未出现明显的微生物聚类，但随着鸡龄增长，我们确实观察到嗉囊、回肠和盲肠中总体微生物种群的变化，以及诸如拟杆菌属、梭菌属和乳酸杆菌属等特定微生物的变化。
