A simple, efficient, and rugged dairy parlor entry gate which is especially useful for identifying animals, minimizing the need for lead animals to back up as the gates swing open, and provides for indexing the animals into proper position. The entry gate preferably includes a pair of opposed stanchions defining therebetween a passageway, at least one and preferably a pair of gate members, and mounting structure for swingably carrying the gate members and mounting them in offset relationship. An antenna may be provided in each of the gate members so that the interrogation field generated thereby swings with the gate member. The gate also preferably includes a motive member for swinging the gate members between an open position allowing the passage of animals therebetween and a closed position which both inhibits the passage of animals into the parlor and indexes the last animal into a proper position.
