Transition Cow Welfare: The Critical Periparturient Period

The three weeks before and after calving are the highest-risk period for dairy cow health and welfare; metabolic diseases affecting transition cows cause significant suffering that proactive management can prevent.

Key Facts

Over 70% of dairy cow diseases occur in the first 30 days of lactation
Milk fever (hypocalcaemia), ketosis, and retained foetal membranes cluster in the transition period
Negative energy balance drives hepatic lipidosis in high-yielding cows
Proactive transition management programmes reduce disease incidence by 30-50%

Welfare Considerations

The transition period represents the most welfare-vulnerable phase of the dairy cow's productive life. The physiological demands of late gestation, parturition, and the onset of lactation overwhelm metabolic reserves in high-yielding cows, predisposing to a cascade of interrelated diseases. Metabolic disease is painful and debilitating; prevention through nutritional management, body condition monitoring, and proactive supplementation is substantially more welfare-effective than reactive treatment.

What You Can Do

Support producers with documented transition management programmes
Advocate for welfare auditing that includes transition disease incidence as a key indicator
Raise awareness that high-yielding dairy cows are physiologically at risk during a critical and predictable welfare period
