Transition Period Management in Dairy Cows

The transition period around calving is the highest-risk welfare period in a dairy cow's year, requiring careful nutritional and health management.

Key Facts

The transition period spans three weeks before and three weeks after calving
Metabolic diseases including milk fever, ketosis and displaced abomasum peak during this period
Up to 50% of high-yielding dairy cows experience a subclinical metabolic condition post-calving
Negative energy balance in early lactation causes fat mobilisation leading to fatty liver
Body condition score at calving significantly predicts transition health outcomes

Welfare Considerations

The transition period concentrates multiple welfare risks into six weeks. The hormonal and metabolic changes of late pregnancy and early lactation create a perfect storm for disease: immune suppression, calcium depletion, energy deficit and physical exhaustion from calving. Cows experiencing transition disease suffer acutely and are at high risk of culling. Preventive nutrition management, appropriate body condition at calving and vigilant post-calving monitoring prevent most transition diseases, with direct welfare and economic benefits.

What You Can Do

Support dairy certification schemes with specific transition management protocols
Advocate for metabolic disease monitoring as a mandatory welfare outcome measure
Choose dairy products from farms with documented low transition disease rates
Support research into transition period management approaches reducing disease risk
