GATE FOR DOMESTIC FARM ANIMALS, AN AUTOMATED MILKING FACILITY INCLUDING SUCH A GATE, AND METHOD OF TRAINING DOMESTIC FARM ANIMALS TO USE SUCH A GATE

摘要

Cows are milked at a facility including a robotic milker, a pen, a first passage leading from the pen to the milker, and a second passage leading from the milker to the pen. Each passage includes a one-way gate. Each gate includes a barrier that turns about a horizontal axis from a quiescent position in only a first direction in response to the cows pushing against the barrier and turns in the opposite direction about the axis to the quiescent position after each cow has passed through the barrier. The barrier includes plural tines that turn independently of each other about the axis in both directions. In normal operation, the quiescent position of the tines is vertical. For training, the quiescent position of the tines is displaced from the vertical so the tines are above the heads of the animals but below their backs.
