Abstract: The cow training device has a bracket attached to the front cross-stanchion of the cow stall, over the neck of the cow. The bracket holds a rear pivotable arm, which has an outer free end adapted to be located spacedly over and proximate the cow's back. The bracket also holds a short selectively powered frontward rotatable whip, linked to a switch which is activated only if the rear arm is upwardly pivoted. If the cow is located at the front portion of its stall and it wants to evacuate, it will arch its back, which will come into upward abutment with the arm outer free end and upwardly pivot the arm. The switch will then be activated, and power will be supplied to the whip which will rotate to sting the cow's neck. To escape this treatment, the cow will normally back up in its stall reactively to position its hind portion over the rear stall gutter. Its arched back will then not abut on the arm outer free end, and the whip will stop rotating, thus relieving the cow of this whipping treatment.
