| Study Title | The impact of grass- and grain-finishing on metabolomic profiles of North American Black Angus Beef cattle. |
| Study Summary | The goal of this study was to compare meat metabolomes (pectoralis profundus) of Black Angus cattle from two commercial US beef finishing systems (pasture-finished on Western U.S. rangeland; n=18 and grain-finished in a Midwest U.S. feedlot; n=18). |

| Project Title: | Analysis of Pasture-Fed vs Grain-Fed Meat in North American Ruminants |
| Project Summary: | The goal of this work was to compare meat metabolomes (pectoralis profundus) of Black Angus cattle from two commercial US beef finishing systems (pasture-finished on Western U.S. rangeland; n=18 and grain-finished in a Midwest U.S. feedlot; n=18). All analyzed samples (pasture-finished and grain-finished) were from cattle harvested in September-October of 2020 and had a Black Angus genetic background. The pasture-finished animals were between 25-27 months of age, while the grain-finished animals ranged from 18-22 months of age at time of slaughter. All cattle were processed in USDA-inspected slaughter facilities and the researchers worked with the producers to collect meat samples (Pectoralis profundus) from 18 individual animals (n=18) per group. Metabolomics analysis was performed by Metabolon (Morrisville, NC). Statistical analyses were performed in ArrayStudio/Jupyter Notebook, MetaboAnalyst, and R. |
