IDENTIFICATION AND ANIMAL FEEDING APPARATUS

摘要

An animal identification and feeding apparatus having a plurality of tags, one suspended from each animal, each tag having a plurality of pockets into which either permanent magnets or non-magnetic filler strips are press fit to form a code. The code is detected by a plurality of spaced reed switches having field modifying magnets interposed between the reed switches. The tag magnets and the field modifying magnets are polarized along an axis of magnetization which is perpendicular to their interfacing surfaces and they are aligned with repelling poles facing each other.
