Cecal Microbial Succession and Its Apparent Association with Nutrient Metabolism in Broiler Chickens.

ABSTRACT: The chicken gut microbiota plays an influential role in nutrient absorption and metabolism. A clear picture of microbiota succession can enhance host nutrition and disease resistance. This study investigated the cecal microbiota succession of broilers between 3 and 42 days after hatching using 16S rRNA gene sequencing and analyzed its potential association with intestinal nutrient metabolism. Microbiota structure differed significantly at different time points depending on the microbiota alpha-diversity or beta-diversity. Proteobacteria and Bacteroidetes promoted succession on days 3 to 7 and days 28 to 35, respectively. Firmicutes and Tenericutes maintained homeostasis on days 7 to 28 and days 35 to 42.
