Youngstock Housing Welfare: Calves and Heifers from Weaning to Joining

The period from weaning to first service is critical for heifer development and lifetime welfare. Housing and management decisions during this period affect both immediate and long-term welfare.

Key Facts

Heifers represent the future of dairy herds — poor welfare during rearing reduces lifetime productivity and welfare
Group housing from weaning improves social competence, feed intake consistency, and welfare indicators
Space allowances at weaning should increase progressively — minimum 1.5m2 at weaning, 2.5m2 at 6 months
Respiratory disease remains the leading cause of heifer mortality between 3 and 6 months of age

Welfare Considerations

Youngstock welfare bridges the vulnerable post-weaning period and the transition to adult dairy life. Under-investment in heifer housing and management results in respiratory disease from crowding and poor ventilation, lameness from slippery floors, and stunted growth that delays first calving. Welfare-positive youngstock management includes group housing with stable social groups, adequate space, good ventilation, and regular health monitoring with prompt treatment protocols. First calving age of 24 months is achievable with good rearing welfare.

What You Can Do

Ensure adequate ventilation in youngstock housing — respiratory disease is the primary indicator of poor air quality
Monitor growth rates monthly using weigh bands to detect nutritional or health welfare issues early
Provide gradual increases in group size and space as heifers grow to maintain appropriate social density
Vaccinate heifers for respiratory pathogens (BRD complex) before housing in autumn
