At one of the farms that are using the Herd Navigator system they have saved $322 (EUR 223) per cow during the first year. This means that the pay back time for the investment was less than 18 months. The savings are calculated on Reproduction, Ketosis, Mastitis and Feed efficiency improvements.

Reproduction – savings

  • Improved heat detection rate
  • Time saved for heat detection
  • Uniform heat detection 365 days a year
  • Improved monitoring of follicle cysts
  • Improved monitoring of lutein cysts
  • Fewer culled cows due to better cyst detection
  • Value of rapid detection of early embryonic death and early abortion
  • Fewer manual pregnancy tests

  • Reduced yield due to clinical and subclinical ketosis
  • Reduction in treatment costs
