Meet the Moocall Calving Sensor, a tail-mounted device that sends a text alert about one to two hours before your cow or heifer is about to calve.
The sensor is a tail-mounted motion sensor that measures specific tail movements. When a cow gets a contraction her tail moves in a particular way, and that is the data the device measures: around 600 pieces of data every second. Once the movement passes a threshold the first high-activity alert fires; if it continues, a second alert follows.
Alerts arrive by SMS to up to two phones, on the free BreedManager app and by email, so you are never relying on a single channel. Moocall is proven to reduce calf mortality associated with difficult calvings by up to 50 percent, and every sensor carries a 30-day money-back guarantee plus a 12-month warranty on the electronics from the date of activation.
