ezFinder BUSINESS Cattle

ezFinder BUSINESS Cattle displays the precise location of cattle on a map and sends alerts when estrus is detected. This cloud application also mathematically displays the time spent on activities such as lying down, grazing, ruminating, and walking. You can create geofences to prevent cows from escaping. This feature helps in maintaining the herd within designated areas by sending alerts if any cow crosses the virtual boundaries.
