A sensor assembly on a swine-activated self-feeder allows monitoring or tracking of individual animal feeding activity, thereby allowing corrective action to be taken in instances of under-feeding or over-feeding by an animal. The sensor assembly includes a sensor on the feed dispenser and, with a printed circuit board to generate a signal corresponding to activation of the dispenser by an animal. The signal can be sent to a computer or website which generates reports on the individual animal's feeding activity.
