Abstract

All [10 single-housed] subjects manipulated the foraging boards, but stereotyped behaviors and activity levels were not significantly affected by the presence of the boards. Subjects used the boards approximately 2 minutes per 30 minute-observation sessions. No reduction in board usage was observed over time of day or on repeated presentation, indicating that there was no novelty effect or reduction in motivation.
