Stronger Cows. Healthier Herds. More Profit.
Backed by over 25 years of research at the University of Guelph, Immunity Technology is a world-leading genetic solution that helps you breed cows with naturally stronger immune systems.

  • Healthier cows with fewer cases of mastitis, metritis, and respiratory disease
  • Lower vet and treatment costs
  • Improved fertility and longevity, keeping cows in your herd longer
  • More profit, with gains that build every generation
    By monitoring immunity in your herd, you’re not just treating disease — you’re preventing it.

  • DIGITAL DERMATITIS

    Immunity+® & Digital Dermatitis (DD)
    Digital dermatitis (DD), a common infectious hoof disease in dairy cattle, can impose significant economic costs on a dairy farm. The cost per cow per year varies depending on disease severity, herd management, and region, but here's a general breakdown:

    Estimated Annual Cost per Cow:
    Range: $40 to $185 per cow per year
    Typical average: $75–$125 per cow per year

    How Immunity+ Helps Fight Digital Dermatitis (DD):
    • Improving Resistance
      Cows with high immune response are better at fighting infections, including bacterial skin conditions like digital dermatitis.
    • Reducing Severity & Recurrence
      Even if high-immune-response cows get DD, they are less likely to develop severe cases or suffer repeat infections compared to cows with lower immune response.
    • Lowering Antibiotic Use
      Healthier animals require fewer treatments, reducing dependence on antibiotics and labor, and lowering costs.
    • Breeding for Long-Term Herd Health
      Over time, using Immunity+ sires builds a herd with stronger natural Immunity+, which improves overall herd resilience to DD and other common dairy diseases (mastitis, pneumonia, etc.)

    Summary: Immunity+ is not a silver bullet. It should be part of a broader hoof health program, including:
    • Good hygiene and housing
    • Regular hoof trimming
    • Proper footbath use
    • Nutrition
