Heat Detection

Good heat detection helps you get:

  • more cows in calf quicker
  • a tighter calving spread

"The best heat detection results are achieved by combining paddock observations with heat detection aids such as tailpaint and heat mount detectors" - DairyNZ InCalf Book.

On average dairy cows will cycle every 21 days, so the cost of just one missed heat at today’s milk price is $189.00*
