Comparisons were made between beef breeding cows outwintered and housed during two winters. At the same level of feeding housed cows gained 16.1-20.9 ㎏ more weight during winter than outwintered cows. However, when both groups grazed together on pasture during the following spring and summer the outwintered cows gained weight faster than the housed cows and reduced the weight difference to only 2.4-4.1 ㎏. There was no carry over effect on calf growth and it is concluded that totally enclosed shelter is unnecessary during winter for Hereford or Angus beef breeding cows in South Korea.
