How cattle are housed during winter significantly affects their welfare, with inadequate shelter, poor bedding, and mud causing chronic discomfort for millions of animals.
Winter housing welfare depends primarily on space allowance, bedding quality, and air quality. Cattle on slatted concrete floors without bedding spend less time lying, show more lameness, and have higher injury rates than cattle on deep straw. Overcrowded buildings increase competition for lying space — cattle forced to stand longer than natural show elevated cortisol. Ammonia from poor ventilation causes respiratory irritation and eye problems. Best-practice winter housing provides deep, clean straw bedding changed regularly, sufficient lying space for all animals to rest simultaneously, good ventilation without drafts, and adequate feed and water access distributed to prevent competition. The contrast between high and low-welfare housed cattle systems represents the range of what winter confinement can mean for individual animals.
