Moocall HEAT

Moocall HEAT is a collar and eartag system that accurately detects standing heat in cows and heifers. The collar is worn by a bull (stock or teaser/vasectomised) and eartags are worn by the rest of the herd. The collar reads proximity, activity and mounting behaviour to accurately alert to standing heat. 

It tells you the exact time of standing heat. 

Whether a cow or heifer repeats.

Due dates and when you can assume they are in-calf.

Bull health (mobility, health and fertility).

Moocall CALVING SENSOR Overview

Learn why over 15000 farms use the calving sensor to reduce labour and increase their bottom line.


The Moocall CALVING SENSOR measures tail contractions to accurately predict when a cow or a heifer will give birth. Today, over 15000 farms around the world use this technology to make their operations more efficient and profitable. 

Now with non-slip rubber

The Moocall CALVING SENSOR now comes with a new red non-slip rubber attachment. This new design innovation means that the sensor can be worn loose on the tail (loose enough that you can easily slide it up the tail) but it will not slip down. 

No need to ratchet it closed, just pull the strap through hand tight and you are good to go. 

More comfortable for the cow, easier to attach and better results.

Thanks Moocall. Last calf of year calved and Moocall was 100% accurate this season. Had an issue with the device and the customer care I got was the best I have ever seen. Great device, great support staff!

Works spot on if attached properly. Gives u piece of mind going to bed. Fantastic after sales service and if contacted will get a reply within 10 minutes even on Sundays. This is my second year using it and will continue using in the future. I save the subscription fee specially in diesel alone as I live 12 miles from my sheds

I can actually sleep all night and not worry about the cows. Just wait until I get the first text usually after the second text cow has calved and calf is trying to nurse. Would recommend to anyone.

Began using moocall mid February 2017 . Have had 4 calves born using this device. First two was from heifers which needed help in delivery. Paid for itself in a short time. Never have we worked with a company that tries any harder to see that the customer is getting all it's questions answered . When you receive texts and phone calls wanting to know how you are getting along that's service. Just another day in paradise in the U.S.

How it works

Moocall BREEDMANAGER makes it really easy to record herd data. Instead of showing you all your animals at any given time, we break them down into Smart Lists.

This means that we only show you the cows that you are interested in at any given moment, such as cows that are due to calve in the next 7 days, or cows due to repeat this week. 

Our quick swipe technology, also makes it really easy for you to add events and data to our app.
