Sheep Indoor Housing Welfare: Space, Ventilation, and Bedding Standards

Indoor housing of sheep during winter and lambing is common in the UK and Europe, with space allowance, ventilation, and bedding quality directly affecting welfare outcomes.

Key Facts

Sheep are housed indoors for 2-6 months per year in many temperate farming systems
Minimum space allowances for housed sheep are specified in the Codes of Recommendations for the Welfare of Livestock
Respiratory disease is the most significant welfare problem in inadequately ventilated sheep housing
Deep straw bedding provides comfort, warmth, and opportunity for normal behavioural expression
Housed ewes approaching lambing require increased space and monitoring

Welfare Considerations

Indoor sheep housing welfare depends on achieving adequate space, ventilation, and bedding quality throughout the housed period. Overcrowding causes social stress, prevents all animals from lying simultaneously, and increases pathogen transmission. Inadequate ventilation with ammoniated air predisposes to pneumonia and chronic respiratory disease. Wet or inadequate bedding causes foot rot, mastitis, and skin disease. Maintaining adequate stocking density and air quality requires regular assessment and willingness to reduce stocking when conditions deteriorate. The welfare improvements available from evidence-based housing standards are large and achievable on most sheep enterprises.

What You Can Do

Implement minimum space allowances for housed sheep based on current welfare codes
Install ridge vents and open-sided housing design that provides fresh air without draughts
Maintain deep, dry straw bedding throughout the housed period
Monitor flock respiratory health during housing as an indicator of ventilation adequacy
Plan lambing accommodation to allow individual attention and additional space for ewes close to lambing
