Abstract: Distribution of Coronavirus Receptors in the Swine Respiratory and Intestinal Tract

Oct 21, 2022

Coronaviruses use a broad range of host receptors for binding and cell entry, essential steps in establishing viral infections. This pilot study evaluated the overall distribution of angiotensin-converting enzyme 2 (ACE2), aminopeptidase N (APN), carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), and dipeptidyl peptidase 4 (DPP4) receptors in the pig respiratory and intestinal tract. All the receptors evaluated in this study were expressed and differentially distributed through the respiratory and intestinal tract. The presence and expression levels of these receptors could determine susceptibility to coronavirus infections. This study may have important implications for the development of research models and the assessment of the potential risk and introduction of novel coronaviruses into the swine population.

Video: Feeding Faba Bean to Pigs - Dr. Eduardo Beltranena

In this special rerun episode of The Swine it Podcast Show Canada, Dr. Eduardo Beltranena from North Carolina State University explains how faba beans can be used in pig diets as a source of both starch and protein. He discusses environmental benefits, inclusion rates, frost-damaged beans, tannin concerns, cultivar selection, and how producers can compare faba beans against cereals and protein meals for cost-effective feeding. Listen now on all major platforms!

"Faba beans provide both starch and protein, competing directly with cereals in swine diets."
