A method and apparatus for remotely reading programmed and programmable memories implanted in livestock and particularly, ruminants, for maintaining animal identification, temperature, medial history, etc. A bolus in commonly implanted in the rumen or first stomach of such an animal to prevent "Tarmumatic Retuculoperitonitis" commonly known as hardware disease in cattle. This disclosure is directed to utilizing a bolus formed from a rectilinear ferrite block magnet of sufficient dimensions and weight for its purpose and attaching a transponder chip to the outer surface of the bolus and including on that chip a plurality of memories capable of having the animal identification on one memory, a temperature sensing device, a programmable memory for programming medical information during the life of the animal and additional memories or specific sensing device which can be read or programmed external of the animal by means of a reader/programmer which can activate and power the transponder chip to make selected memory readings or programming. An antenna for the transponder operation is wrapped around the bolus magnet and attached thereto. A protective sleeve may be utilized to ease implant of the device.
