NON-CONDUCTIVE DAIRY PARLOR ENTRY GATE

摘要

A non-conductive dairy parlor gate (10) is provided which retains the strength and corrosion resistance of magnetically conductive materials while permitting the gate (10) to swing into and/or through an electromagnetic field generated by an electronic identification system (16) for use with animal-worn transponders (63). The gate (10) includes at least two magnetically conductive parts (18, 20) connected by an electrically non-conductive member to interrupt the formation of a magnetic loop. The gate (10) may include additional structural members (31, 33-35) for strength and which inhibit a dairy animal (13) from placing her head through the gate (10). The gate (10) is used as a part of a dairy parlor (11) and placed along an animal passage lane (50) to prevent dairy animals (13) from moving their transponders (63) past the identification system (16) prematurely. The gate (10) may be positioned adjacent a milking stall (14) to retain one dairy animal (13) in position while inhibiting the passage of a second set of animals (13) into the milking stalls (14).
