Well, I tried these on some fall calving pairs. Took a bit to figure them out. Results are as follows-
30% of the calves had to be redone the next day. I took a pair of pliers and really tightened the wingnut.
one of them lost the plastic ball on the nose part, so it wasn't operator error.
2 calves had them out two days later.
One heifer I swear has become an artist at getting hers out. Sems like i find them along a fence line like they are hooking them and pulling them off.
Cows bellered a fair amount first two days. Silent on the third day.
I see a couple of calves are smart enough to manipulate a teat around these things, but mothers bags are pretty engourged, so I am thinking they aren't getting much.
Will see in a few days when I pull the cows out.
Calves have been creep fed and vaccinated three times. They are growing well and hopefully will see minimal sickness.
