Farmed Cattle Transition Cow Welfare Periparturient Period

The transition period around calving is the most welfare-critical phase of the dairy cow production cycle, with metabolic diseases, pain, and immune suppression peaking in the weeks before and after birth.

Key Facts

The three weeks before and three weeks after calving - the transition period - account for the majority of disease events in a dairy cow's annual cycle.
Subclinical hypocalcaemia affects up to 50% of multiparous cows at calving and predisposes them to a cascade of other conditions including mastitis and displaced abomasum.
Negative energy balance after calving forces cows to mobilize body fat reserves, with severe cases leading to clinical ketosis and liver disease.
Pain at calving from dystocia (difficult birth) and subsequent uterine conditions is often inadequately addressed with analgesics on commercial farms.
Transition cow management - including nutrition, body condition at dry-off, and calving pen design - has the single largest influence on health outcomes.

Welfare Considerations

The transition cow represents one of the most significant welfare challenges in dairy farming. Multiple simultaneous physiological stressors - immune suppression, metabolic disease, parturition pain, and the stress of calving - occur in rapid succession. Good transition management requires attention to nutrition in the dry period, appropriate body condition scoring, clean and comfortable calving facilities, colostrum management for the calf, and prompt recognition and treatment of metabolic and infectious conditions. Analgesic use at calving for difficult births is increasingly recognized as a welfare requirement, not an optional extra.

What You Can Do

Support dairy producers with transparent transition cow health records and low disease incidence.
Advocate for mandatory analgesic protocols for difficult calvings and painful post-partum conditions.
Choose dairy products from farms with low culling rates and good cow longevity data.
Support research into better transition cow nutrition protocols and disease prevention strategies.
