Background
Wendy and David Harker are really enjoying the health and breeding information they get from Allflex collars. It’s enabled them to have a decent break between calving and mating, as well as improving in-calf rates and cow health.

“Our staff love the collars now. There’s no tail paint, no scratches and no bulls.”
