FFAR Research Aims to Protect Dairy Cattle Against H5N1

Jun 27, 2025

Although bird flu, or H5N1 influenza, had been primarily limited to wild migratory birds and sporadic outbreaks in commercial poultry operations, it was detected in U.S. dairy cows in March 2024. Since then, H5N1 has spread rapidly in dairy cattle across multiple states, and the industry has limited tools to protect their herds. Together, the Foundation for Food & Agriculture Research and Purdue University are investing $301,562 into a Rapid Outcomes from Agricultural Research (ROAR) grant to develop an H5N1 vaccine for dairy cows.

While H5N1 does not have high mortality rates in dairy cows, the infection causes decreases milk production and milk quality, causing significant economic losses for farmers. The recent detection of H5N1 in humans, dairy cows and non-traditional host birds indicates that this virus poses new threats to other non-avian species.

Video: Alternatives to Antibiotics - Dr. Luciana Rossi

In this special re-run episode of The Swine Nutrition Blackbelt Podcast, we bring back our conversation with Dr. Luciana Rossi, Associate Professor at the University of Milan, who discusses alternatives to antibiotics in swine nutrition. She explores antimicrobial resistance, the role of functional ingredients, and the potential of biochar in improving gut health and sustainability. Tune in now on all major platforms!

"Biochar, a vegetable charcoal produced by pyrolysis, has shown potential in reducing diarrhea incidence and improving gut health in weaning piglets."
