What producers say

“We have two visual tags so it’s easy to spot a cow. And then we got the electronic ID. We can find animals easily. With 400 cows in the corral it’s really hard to go by a piece of paper, cow by cow by cow. That takes forever, so that’s why we use EID.”

Case VanderMeulen, Owner, Coulee Flats Dairy
