Negative Energy Balance in Dairy Cows: Welfare Management at Peak Lactation

The transition period around calving creates unavoidable negative energy balance in high-producing dairy cows, with welfare management critical to minimise metabolic disease.

Key Facts

Peak milk production occurs 4-8 weeks after calving when feed intake has not yet reached maximum
Negative energy balance during this period mobilises body fat causing ketosis risk
Subclinical ketosis affects 40-60% of cows in some herds reducing production and welfare
Ketosis predisposes to displaced abomasum, metritis, and early culling
Transition cow management including diet formulation and monitoring is the most impactful welfare intervention

Welfare Considerations

Cows in severe negative energy balance experience metabolic ketosis causing reduced appetite, lethargy, and susceptibility to multiple concurrent diseases. The domino effect of transition disease means a cow that develops ketosis is more likely to develop displaced abomasum, metritis, and mastitis, each adding to the welfare burden. Subclinical ketosis causes chronic low-grade welfare impacts on appetite and immune function without obvious clinical signs. Proactive transition cow management with targeted nutrition significantly reduces both clinical and subclinical welfare impacts.

What You Can Do

Implement transition cow monitoring using milk or blood ketone testing in the first 2 weeks post-calving
Formulate pre-calving diets to achieve appropriate body condition and reduce transition disease risk
Treat subclinical ketosis proactively rather than waiting for clinical signs
Ensure adequate access to feed and water for fresh cows especially in competitive housing situations
Work with your vet and nutritionist to develop a written transition cow management protocol
