Collars that collect and analyses critical data for each individual cow’s reproductive cycle, rumination patterns and health status.


Light weight, adjustable and waterproof. Designed with cow comfort in mind.

The collar goes around the cow’s neck, with the blue tag sitting on the left side of the neck closest to the cow’s oesophagus. The weight at bottom of collar is there to keep the blue tag against the oesophagus and is coated in a rubberised plastic to minimise noise if it hits metal. The collar weighs 1kg.

Cows tend to adapt quickly to wearing a collar.

The strap is designed to fit firmly around the cow’s neck. In the unlikely event the collars gets caught on something, the strap will tear if enough force is applied, releasing extra space to allow the cow to back out of the collar.
