ABSTRACT OF THE DISCLOSURE A system is disclosed for determining the amount of food consumed in a given period of time by each of a plurality of animals, such as cattle. A feed station which the animals can enter individually and separately for feeding purposes, includes a feed hopper mounted on a scale. A photo-electric sensing device determines the presence of an animal at the feed hopper. Actuation of the photo-electric sensing device will energize an interrogation coil which means an electromagnetic pulse to the animal to activate an identification tag attached to the animal. The identification tag is a small R.F. trans- mitter capable of transmitting R.F. pulses equal in number to the identification number assigned to that particular animal. Each identification tag has its own source of power which is momentarily engaged during the period of time that the identification tag is transmitting R.F. pulses for identifying the given animal. A magnetic reed switch is momentarily actuated by the electromagnetic pulse from the electromagnetic interrogation coil. The overall apparatus is provided with an R.F. receiver which receives the pulses from the identification tag transmitter and which addresses a memory cell in a memory corresponding to the number of the given animal. Thereafter, a weight-sensing device or scale senses the amount of feed consumed by the given animal and transfers this information into the memory cell corresponding to that animal. When the animal leaves the feed station, the information as to the amount of food consumed by that given animal is "dumped" into the memory cell corresponding to that given animal on top of any other information that is presently in that memory cell with regard to that animal. after the animal departs, the various portions of the apparatus will be returned to zero in readiness for the entry of the next animal.
