An automatic animal feeding apparatus including a feeding portion, a feed supplying portion, and a feed control portion; the feeding portion including a feeding station, the feeding station including a trough member, the feed supplying portion including feed storage mechanism associated with the feeding station, transfer mechanism associated with the feed storage mechanism capable of selectively conveying feed material to the feed trough member, the feed control portion being operatively connected to the transfer mechanism, the feed control portion including animal identifying mechanism, the animal identifying mechanism including a light source, a plurality of spaced phototransistors adjacent to the light source but normally shielded therefrom, the light source and the phototransistors being disposed below and adjacent to the feed trough member and arranged with their active surfaces in a generally vertical plane, electrical circuitry connecting the phototransistors with deciphering, feed schedule memory and comparing mechanism, whereby light reflected from the light source onto one or more phototransistors by an identifying tag hanging from the neck of an animal positioned with its head in the feed trough member causes activated phototransistors to send signals to the deciphering mechanism and depending upon the feed schedule in the memory mechanism, the comparing mechanism will activate the feed transfer mechanism to convey predetermined quantities of feed material from the storage mechanism to the trough member.
