This study was carried out to determine the maintenance and social behavior characteristics of Hanwoosteers by season. Forty eight Hanwoo steers were video-recorded at 15, 17 and 19 months of age forbehavior measurement. Hanwoo steers spent more feeding time (p<0.05) in autumn than in summer and/orwinter. Standing time was linearly increased (p<0.05) along with seasonal transition, from summer towinter. The rice straw intake speed was the fastest the summer, whereas the concentrate intake speed wasrelatively fast in winter. Furthermore, Hanwoo steers showed more behavior time and count for lying down(p<0.05) and drinking (p<0.05) in summer than in autumn and winter. Also, Hanwoo steers spent less count(p<0.05) self grooming and scratching in summer.
