Identification of the Intestinal Microbes Linked to Growth Rate in Broilers

This current study was aimed at identifying the bacteria that are associated with the growth of broilers in a commercial production setting. Ten Cobb-500 broilers with extremely high body weight (BW), ten chickens with medium BW, and ten chickens with extremely low BW were randomly selected for each sex from a house of approximately 10,000 chickens on day 42. Cecal contents of 60 animals were subjected to DNA isolation and 16S rRNA gene V3-V4 region sequencing.
