Research program focused on the microbiological mechanisms underlying feed efficiency, enteric emissions, and nutrition in beef cattle. Posts are my own.

🎉 Congratulations to @Rachel_flinch on successfully defending her MS thesis! Her work explored how the #rumen #microbiome influences #MethaneEmissions & #FeedEfficiency in forage-based beef #cattle operations. Excited to see what’s next for her! @UTAnimalScience @UTAgResearch

A great outing today with a delegation of Brazilian researchers and educators at the @UTIAg. Really enjoyed the conversations, exchanging ideas, and getting to know each other’s work. Excited for future collaboration! Many thanks to the @utsmithcenter for making it possible.

After working with efficiency & resilience phenotypes long enough, you realize it’s rarely about which microbes are present — it’s about what they’re doing & when. That realization changes how you sample, analyze, & interpret nearly everything. #RumenMicrobiome @UTAgResearch

Feed efficiency isn’t just the animal — it’s the animal & its microbes. We’re treating feed efficiency as a whole-system trait — integrating rumen microbes, host genomics, & precision phenotypes to understand why some animals are biologically more efficient than others.
