Designed to test cows' milk for signs of mastitis. Simple to use: discard first stream of milk from quarter to be tested. Then hold blotter in slanting position so milk stream will first cover dark area and run down over yellow round area.
I borrowed a couple of these mastitis indicators from a friend and it worked so well that I am placing an order for them for myself and for another friend who also raises goats. I was able to catch the mastitis issue extremely early and provide proper treatment.
"Helps catch mastitis early"
This works great, changes color to help catch mastitis early and no more guessing.
