Vandeleest, J., Capitanio, J., McCowan, B.

Abstract

A significantly higher proportion of nursery reared animals and a significantly lower proportion than expected of animals reared in out-door housed groups developed abnormal behavior. Our results suggest [sic] that time spent in restricted housing ... is a predictor of abnormal behavior.
