“The WP of all livestock products – beef, pork, chicken, turkey, milk, and eggs – increased considerably from 1.8 times for beef to 5.1 times for milk,” said Mesfin Mekonnen, Ph.D., Assistant Professor at the Department of Civil, Construction, and Environmental Engineering at the University of Alabama and one of the lead authors of the research study. “In evaluating opportunities to increase WP, one area that we examined in depth was utilizing distiller’s grains and other crop by-products as substitutes for corn and soybeans. This research will help set benchmarks and identify critical factors affecting WP to help meet the growing global demand for livestock products.”
