“Whether you are thinking about buying a new squeeze chute, remodeling your livestock-working facility or changing your load-out area; remember that all EID functions are left-ear based,” says Erwin Quinn, president of Gallagher Animal Management Solutions.

The standard has been established for all EID tagging to occur in the left ear — as a result, all data retrieval must occur from the left side of whatever process is being performed. Producers now must think about left-side room and accessibility for tagging animals and reading tags with a hand-held reader, as well as about strategic placement of fixed, panel-type readers for alleyways or loading chutes.
