Imagine a world where cows are naturally resistant to devastating diseases like avian flu. Sounds like science fiction? Think again. Dr. Bonnie Mallard, a pioneering researcher at the University of Guelph, has developed a groundbreaking technology that’s turning this vision into reality. Her High Immune Response (HIR™) technology is revolutionizing animal health, and it’s already making waves in the fight against avian flu. But here’s where it gets controversial: could this technology render traditional culling practices obsolete? Let’s dive in.
For over 35 years, Dr. Mallard has dedicated her career to improving animal health, and her work has paid off in spades. Her HIR™ technology identifies animals with naturally strong immune systems, allowing farmers to breed healthier herds over generations. The ‘Aha!’ moment came during her undergraduate studies, when she realized that just as genetic defects can cause inherited disorders, robust immune genetics could lead to powerful disease resistance. This insight has since evolved into a game-changing solution for farmers worldwide.
Here’s how it works: special antigen test kits stimulate an animal’s immune system, and those with the strongest responses are labeled high-immune responders. Farmers then breed these animals to improve the overall health of their herds. The results? Offspring with Immunity+® genetics are nothing short of remarkable. They’re 50% less likely to develop infectious diseases, require fewer medications, grow faster, live longer, and produce higher-quality colostrum. For farmers, this translates to savings of hundreds of dollars per animal annually. No wonder HIR™ is one of the most profitable patents ever to emerge from the University of Guelph.
But here’s where it gets even more exciting: HIR™ technology is now proving its worth against avian flu. In 2024, avian flu jumped from poultry to dairy cows in the U.S., sparking fears of catastrophic economic losses. However, Dr. Mallard noticed something intriguing: Immunity+® cows exposed to the H5N1 virus were significantly less affected. Anecdotal reports from U.S. producers suggested these cows weren’t getting as sick and were recovering faster. This led to a landmark study published in the Journal of Dairy Science Communications, where researchers assessed over 15,000 cows from six dairy herds with confirmed avian flu outbreaks. The findings? Cows with high Immunity+® breeding values were 24% less likely to require treatment—a clear sign of natural resistance.
And this is the part most people miss: while avian flu typically disrupts milk production, causing an average loss of $504 USD per affected cow, Immunity+® cows experienced significantly fewer milk losses. Dr. Mallard argues that culling infected animals—a common but controversial practice—is not a sustainable solution. Instead, HIR™ technology could prevent outbreaks by giving animals the tools to fight off pathogens naturally.
But here’s the kicker: this strain of avian flu hasn’t yet been detected in Canadian cows, but Dr. Mallard warns that borders won’t stop it. “If we think the border is going to stop avian flu from jumping to cattle in Canada, no way,” she says. Her study shows that animals bred for better health genetics will be better prepared to combat the disease when it arrives. In other words, while vaccines are being developed, HIR™ technology is creating naturally resistant animals—a two-pronged approach to disease prevention.
The technology isn’t stopping at cows. Dr. Mallard is now applying HIR™ to other species, including companion animals, sheep, turkeys, and beef cattle. For instance, beef cattle transported over long distances often fall ill with diseases like shipping fever pneumonia. By working with the Canadian Angus Association and Semex, Dr. Mallard is identifying which cows are more resilient and why. Similarly, her collaboration with Hendrix Genetics aims to protect turkeys using tailored antigen tests. Even ostriches, a species rarely studied in this context, may benefit from this research.
Dr. Mallard’s work has earned her Canada’s top research awards, including the Governor General’s Award for Innovation and the NSERC Synergy Prize. She credits the University of Guelph’s Research Innovation Office for helping her forge critical industry partnerships, particularly with Semex, which has been instrumental in bringing HIR™ to market. “For a university professor to get a technology into the marketplace, they must have a really good business partner,” she says. “I give so much credit to Semex.”
Her journey also highlights the power of mentorship. Dr. Ted Burnside, her master’s supervisor and a pioneer in animal improvement, introduced her to Semex’s CEO, Dr. Moe Freeman. That meeting led to immediate funding for her research—a moment she now calls “the speed of trust.”
This groundbreaking work has been supported by the Ontario Agri-Food Innovation Alliance, Ontario Genomics, NSERC, and industry partners like Semex, Hendrix Genetics, and Canadian Angus. But the real question remains: Could HIR™ technology make culling practices obsolete? And if so, what does that mean for the future of animal agriculture?
What do you think? Is Dr. Mallard’s approach the key to sustainable disease prevention, or are there limitations we’re not considering? Share your thoughts in the comments—let’s spark a conversation!
