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.

  • INTERDIGITAL HYPERPLASIA

    Immunity+® & Interdigital Hyperplasia (IH)
    Interdigital hyperplasia (IH) — also called interdigital fibroma or "corns" — is a chronic hoof condition where a fibrous growth forms between the claws, causing pain, lameness, and economic loss on dairy farms. Though less common than digital dermatitis or sole ulcers, IH can be persistent and costly, especially when it leads to lameness or requires surgical intervention.

    Estimated Cost of Interdigital Hyperplasia (IH):
    $90 to $350+ per affected cow per year

    How Immunity+ Helps Fight IH
    • Improved Resistance to Secondary Infections
      • IH often becomes problematic when secondary bacterial infections occur (e.g., Fusobacterium necrophorum causing foot rot).
        • Immunity+ cows are better equipped to resist these infections, keeping lesions cleaner and less inflamed.
        • This reduces pain, lameness, and need for antibiotics.
    • Faster Healing from Inflammation or Injury
      • Interdigital fibromas can form after repeated trauma or chronic inflammation between the toes.
        • High immune responders manage inflammation more effectively.
        • They are less likely to develop persistent swelling or fibrotic tissue growth.
        • If IH is surgically removed or treated, Immunity+ animals tend to heal more quickly and with fewer complications.
    • Better Overall Hoof Health
      • Immunity+ cows are:
        • Less prone to digital dermatitis, foot rot, and abscesses
        • More resilient to hoof-related diseases
        • These factors reduce compensatory gait stress and trauma that can trigger IH
    • Lower Risk of Chronic Lameness
      • Even if a cow develops IH, a stronger immune response can:
        • Reduce severity of swelling or infection
        • Limit lameness duration
        • Help the cow stay in the herd longer and more productive

    Summary: Semex’s Immunity+ doesn't directly prevent interdigital hyperplasia, but it strengthens the cow’s immune system, making her more resilient to the complications, infections, and chronic issues that worsen IH. It’s a smart, long-term strategy for improving hoof health and reducing lameness-related losses.
