Farmed Dairy Cow Welfare: Transition Period Management

The transition period around calving is the highest-risk period for dairy cow health and welfare. Evidence-based management dramatically reduces disease incidence and suffering.

Key Facts

The transition period is associated with the majority of production diseases in dairy cows including milk fever, ketosis, displaced abomasum, and metritis
Negative energy balance in early lactation causes cows to mobilize body fat, producing ketone bodies that can cause clinical ketosis
Milk fever from hypocalcemia occurs when calcium demand for colostrum and milk production exceeds dietary supply
Fresh cow monitoring programs using ketone testing, rectal temperature, and body condition assessment enable early detection
Dry cow nutrition in the final three weeks before calving is critical - overconditioned cows face significantly higher transition disease risk
Adequate bunk space, clean water access, and minimal social stress during transition reduce disease risk substantially
Freshly calved cows need clean, comfortable calving areas with adequate space and bedding
Subclinical diseases including subclinical ketosis affect welfare significantly without obvious clinical signs

Welfare Considerations

The transition period concentrates welfare risk in dairy cows - the physiological demands of late pregnancy, parturition, and the onset of lactation simultaneously challenge calcium metabolism, energy balance, and immune function. Cows that develop clinical diseases during this period experience significant suffering, and subclinical versions impair welfare without being obvious. Evidence-based transition management is both a welfare and economic priority. Investment in transition cow management is one of the highest-return welfare interventions available in dairy farming.
