Understanding Mastitis

Bovine mastitis is harming your cows and your profits

Mastitis is the most widespread disease in the dairy industry, costing New Zealand farmers at least NZD$200-400M and farmers globally $40B every year.

It is typically caused by bacteria entering through the teats and infecting the udder tissue, and can either exist as sub-clinical mastitis (no visual signs) or clinical mastitis (redness, clotted milk, swelling).

There are a range of different mastitis types, some that are contagious and can jump from cow to cow (Staph. aureus), and others that come from the environment (E. coli and Strep uberis).

All types of mastitis cause significant losses by:

All types of mastitis cause significant losses by:
  • Increasing your herd somatic cell count, dropping your payout from most processors
  • Reducing milk production by 2.1% for every doubling of somatic cell count over 100,000 cells/ml
  • Forcing you to treat infected cows with antibiotics and withhold their milk, and even cull them if treatment doesn’t work
  • Wasting hours of your time and energy trying to find it by stripping/RMT your herd.
