To determine how many Moocall calving sensors you need to consider your herd-size and calving pattern.

We normally recommend one sensor for a herd size of 30-40 cows. This will be dependent on your calving pattern (A 50 cow herd calving year-round differs greatly to one calving over 12 weeks!) and how you plan on managing your sensor.

For example a lot of our farmers operating a very tight calving spread would find the Moocall most useful at the beginning and end of calving once numbers have slackened off. In this situation a farmer may only need 1 or 2 sensors.

If managed effectively the sensor can pick up circa 6 calvings per week as it can be moved straight on to the next cow due to calve. The long battery life of 30 plus days helps to facilitate this.
