I can not imagine why something like this would have ever been used. This device was used to ween a calf from its Momma. The item would be placed in the calves nose when it was time to ween and whenever the calf would approach the teet to nurse it would poke the cows udder, it obviously would hurt and she would kick the calf away.
Now we just bring the calves that we want weened into the lot and keep them away from their Mommas. They can still go nose to nose through the fence (less stress on the calf) but they can’t suck. We keep them in the lot for about 7 to 10 days until they are all bawled out and their Mommas have given up and moved out to pasture. Then the lot is opened and the fun begins as they realize they can run and buck with their tails straight in the air.
