Over the course of his career, Billy Hargis published hundreds of scientific publications that resulted in dozens of licensed inventions. Of all his achievements, though, he points to the scores of students he mentored and collaborators he worked with as being the greatest sources of fulfillment.

Can a feed supplement given to fall-born calves during summer months help them handle heat stress? Animal Science faculty members are looking into it with support from an @ArkBeefCouncil grant? Read more: aaes.uada.edu/news/fall-calv… @AginArk @uarkbumpers

Feed Supplement May Help Fall Calves Cope With Summer Heat

Summer heat can be costly for Arkansas cattle producers, slowing cattle growth and potentially reducing meat quality. A new study at the AAES aims to help fall-born calves better withstand heat...

In food safety, just because it's a dry environment doesn't mean it's resistant to bacterial pathogens. In a Center for Food Safety study, pathogens introduced in dry conditions often persisted as long as, and sometimes longer than, those in wet conditions.
