A system for automated recording and analysis of feeding behavior

We have designed and implemented a system that utilizes a network of top-loading balances digitally interfaced to a Macintosh computer. The system simultaneously collects two forms of data which allow the evaluation of the animal's biting and/or licking behavior in addition to cumulative food intake and meal patterns. The system is capable of resuming data acquisition following a power failure without user intervention. Plexiglas cages utilized with the system features adjustable tunnel feeders and are appropriate for use with small rodents. Given appropriate caging, the system may be utilized to evaluate the feeding behavior of other species.
