Reducing Lameness - Monitor

19 April 2023


Opportunities for conversations around Reducing Lameness:

  • NZ and Australian studies found dairy farmers were typically identifying 25% of clinically lame cows in the herd. This means that on any given day 75% of clinically lame cows are undiagnosed and untreated.2 3
  • Many farmers only record lame cows treated with antibiotics. All case of lame cows should be recorded, irrespective of treatments.
  • Financial impact of lameness in NZ is conservatively estimated at $250 per case or $15,000 per year (assuming herd size of 420 cows with lameness incidence of 14%).1
  • Access your farmer clients’ Fonterra Insights Report to benchmark and identify opportunities to help improve dairy herd health and wellbeing.

  • Most NZ lameness cases are due to claw horn lesions, usually white line or sole disease. 
  • Lift the hoof of each lame cow to diagnose the likely cause. In New Zealand 80% of lameness is due to inflammatory changes rather than bacterial infection. The damage to the soft tissue (corium) slowly grows down with lesions visible several months later. 
  • Identify lame cows promptly – could vets or technicians help with this?

AgriHealth Resources include:

Cow Hoof Model

Show farmers the differences between a healthy hoof and a hoof with damage to the
corium. Explain the long-term impacts of lameness, and how to keep cows in the
milking herd for longer.
