With the support of the SARE grant, we evaluated the difference in the gut microbiota composition between Brahman and Angus cattle throughout the production lifecycle using the multibreed Angus-Brahman herd, which contributes to the variation in immune function and growth rate between the two breeds. We identified disease-resistant Brahman cattle harbored a higher abundance of beneficial butyrate-producing bacteria (e.g., Roseburia and Oscillospira) throughout life. These results shed light on developing potential probiotics from the butyrate producers.
