Bulling among steers is an abnormal behavioral trait and is a common health and economic problem in feedlot operations. Factors associated with the buller-steer syndrome are hormonal implantation, seasonality and environmental conditions, stress, overcrowding, and social interaction between individuals. Research has examined relationships between these and other factors and buller occurrence. Boredom of feedlot cattle may contribute more to buller occurrence and other undesirable behavior than we might suspect. Research is needed to determine the feasibility of enriching the environment of penned livestock in general, the goal of which would be, in theory, eliminating undesirable behavior and increasing performance.
