Livestock Nutrition Lab

EST. 2017

2019 Research Publications

As Year 2020 commences, the livestock nutrition lab would like to highlight our research papers from 2019.

Our lab is currently studying how nutritional interventions impact the gastrointestinal microbiome and metabolome of ruminant to improve efficiency of ruminant production systems.

Special thanks to our funders (USDA/NIFA, Alltech Inc. and Land O’ Lakes) and collaborators (University of Kentucky and University of Florida).
