FFAR Research Aims to Protect Dairy Cattle Against H5N1

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: Season 6, Episode 10: Defining Resiliency and the Research Driving Swine Health Forward

Genetic research and new technologies continue to influence the future of swine health and production efficiency. In this episode, we explore how research and technology are being used to support stronger, more resilient pigs, while also improving overall production outcomes. In this episode, we are joined by Dr. Jenelle Dunkelberger, geneticist with Topigs Norsvin, to discuss both routine and emerging strategies for improving piglet, pig, and sow livability. She outlines two primary approaches to enhancing resiliency: gene editing and traditional selective breeding. Continuing the resiliency conversation, we also hear from Dr. Lucina Galina, director of technical research projects at the Pig Improvement Company. She shares insights into ongoing gene-editing work focused on PRRS, detailing the pathway to success, regulatory and practical considerations, and the questions that still remain as the technology evolves. Together, these conversations provide a closer look at how research, genetics and innovation are shaping the future of swine health and livability.
