Cow Trainers are used in the stanchion barn where they are
connected to an electric fence charger to give cows a slight shock when they
hump to evacuate. Cows are soon "trained" and the stanchions stay
much cleaner. EasyFlex Cow Trainer
eliminates the need for clips. Simply tie the trainer hanging lines to the
overhead wire. Then wrap the insulated wire lead from the crossbar to the
overhead hot line.
