Periparturient Cow Welfare: The Critical Transition Period

The periparturient period (three weeks before to three weeks after calving) is the highest-risk welfare period in a dairy cow's life. Metabolic diseases, infections, and reproductive issues cluster in this window.

Key Facts

Approximately 75% of all dairy cow diseases occur in the first month after calving
Hypocalcaemia (milk fever) affects up to 25% of multiparous cows and predisposes to other conditions
Negative energy balance in early lactation causes ketosis, fatty liver, and reproductive failure
The transition period is when most unplanned culling decisions originate — welfare deterioration drives economic losses

Welfare Considerations

Periparturient welfare requires proactive management rather than reactive treatment. Predrying metabolic interventions (negative DCAD diet, vitamin E and selenium status), monitoring body condition score, and ensuring adequate dry matter intake in the transition pen all reduce disease incidence. Early detection of hypocalcaemia, ketosis, and retained foetal membranes through routine monitoring prevents progression to more serious welfare compromise. Individual cow monitoring and early intervention is the hallmark of welfare-positive transition management.

What You Can Do

Implement routine ketosis screening (BHBA testing) in the first week after calving for all cows
Ensure adequate feeding space (60cm per cow minimum) in transition pens to prevent feed competition stress
Advocate for body condition score monitoring throughout the dry period as a welfare-positive management tool
Support farmer training in periparturient disease recognition and early intervention protocols
