Overview

The research in the Krusinski Lab is performed at the nexus of food and animal science. We investigate the effects of agricultural practices on meat nutrient density and authenticity. The Krusinski Lab performs high-throughput multi-omics work to measure fatty acids, vitamins, minerals, secondary metabolites, and animal health biomarkers in beef. Most of the work is performed on grass-finished cattle, and we are deeply interested in the use of supplemental feeds and agricultural by-products to enhance meat nutrient density and animal welfare. We love solving rancher-identified issues, so if you are a rancher and would like to collaborate, please contact us!
