A non-conductive dairy parlor gate is provided which retains the strength and corrosion resistance of magnetically conductive materials while permitting the gate to swing into and/or through an electromagnetic field generated by an electronic identification system for use with animal-worn transponders. The gate includes at least two magnetically conductive parts connected by an electrically non-conductive member to interrupt the formation of a magnetic loop. The gate may include additional structural members for strength and which inhibit a dairy animal from placing her head through the gate. The gate is used as a part of a dairy parlor and placed along an animal passage lane to prevent dairy animals from moving their transponders past the identification system prematurely. The gate may be positioned adjacent a milking stall to retain one dairy animal in position while inhibiting the passage of a second set of animals into the milking stalls.
