History

 

It all started with milk churns … 

 

It was farmer’s son Karstein Horten who was the inspiration behind OS ID® in 1936 when he hammered out his first ear tags from the handles of discarded milk churns.

The product turned out to be as simple as it was brilliant. During the first year, several hundred ear tags were sold to farmers in the surrounding area. Today, OS ID® is an international, leading manufacturer of livestock identification and we have customers in several parts of the world.

These days, OS ID® is a modern technology company run by Karstein Horten’s granddaughter, Wenche Wikan Ligård.
