Most Accurate Heat Detection

The best fertility management

Good fertility management means that cows calve at optimal intervals, maintaining milk production at the highest possible level.

Years of research and field experience have demonstrated the strong, direct correlation between the timing of estrus and cows' increased walking activity. Based on this crucial finding, the Afimilk team developed AfiAct, the world’s leading automatic heat detection system.

How to increase the pregnancy rate and reduce the overall fertility cost per cow?

Measuring the walking, resting and standing activity of milk cows and heifers, AfiAct’s methodical sensor technology and system provide round-the-clock monitoring. The result: higher and more precise heat detection rates.

Better heat detection leads to higher pregnancy rates and fewer open days; saves labor and drug costs; saves on observation, pregnancy checks and hormone treatments.

AfiAct II vs. visual observation and AfiAct II + OvSync = Savings between $100 to $150 per cow, per lactation.


For the most accurate heat detection

Based on the widely-used AfiAct Internet of Cows™ technology, the next-generation AfiAct II sets new standards for heat detection. Extremely sensitive and accurate, the system picks up what that other solutions miss.

AfiAct II:

  • Provides early detection of anestrus, abortion and cyclic disorders
  • Records history of heat patterns throughout cow’s entire life
