Cow Trainers are used in stanchion barns where they are
connected to an electric fence charger to give cows a light shock when they
hump to evacuate. Cows are soon "trained" and the stanchions stay
much cleaner. Coburn Notched Bar Cow Trainer has a solid, hard-steel flat bar,
points at a 98-degree angle and is equipped with a quick-adjust clip and
insulator.
