Calf Rearing Welfare: From Birth to Weaning

The welfare of dairy calves from birth through weaning is a period of high vulnerability requiring careful management to prevent disease, suffering, and poor development.

Key Facts

Dairy calves are typically separated from their mothers within 12-24 hours of birth
Calves kept with their dams for extended periods show better immune status and social development
Scours (diarrhoea) is the most common calf disease and can cause rapid death from dehydration
Social housing of calves in pairs or groups from the first week reduces stress and improves welfare
The transition from milk to solid feed at weaning is a period of nutritional and behavioural stress

Welfare Considerations

Early separation of dairy calves causes acute distress in both cow and calf, with vocalisation and searching behaviour documented for several days. Calves raised in isolation on minimal milk rations show higher disease susceptibility, poorer cognitive development, and lower social competence than calves raised in enriched, social environments. Extended milk feeding volumes have been shown to improve health and welfare during the pre-weaning period but require management of weaning transition. Group housing provides opportunities for social learning, play, and the expression of natural behaviours. Dam-rearing systems are commercially rare but show strong welfare outcomes.
