When H5N1, commonly known as avian influenza, was detected in U.S. dairy cattle in early 2024, the industry faced a whirlwind of uncertainty. With symptoms that varied from cow-to-cow and herd-to-herd, early diagnosis was difficult, response coordination was slow, and containment proved complex. But with challenge comes opportunity.
In this presentation, Dr. Jennifer Spencer, and Elizabeth Galbraith will share key insights from the front lines of the H5N1 outbreak, including the realities dairy producers faced and the critical lessons learned for the future.
You’ll hear how data, diagnostics, and a proactive approach to herd health could redefine the way we respond… not just to H5N1, but to emerging diseases moving forward.
