AfiAct™ detects heat by measuring the activity of a cow. This method is based on numerous studies and scientific research that showed that correlation between the rise in activity of the cow and its heat event is very high.
See the sharp increase in the activity of the animal at day 63 of the lactation. The cow was not inseminated at that heat event because it was too early in the lactation. The next heat event occurred exactly 22 days later (day 85) and the cow was inseminated on that date. Note the stable activity line that follows that heat – no more heat periods afterwards. Indeed, that cow was checked and confirmed pregnant 45 days later.
