Dairy Cow Lying Time and Welfare

Adequate lying time is essential for dairy cow welfare and productivity, with significant consequences when it falls below requirements.

Key Facts

Dairy cows should lie down for 10-14 hours per day for optimal welfare
Each additional hour of lying time beyond 8 hours adds approximately 1.7 kg of milk
Overstocked barns, inadequate cubicle numbers and poor cubicle design reduce lying time
Lame cows show reduced lying time creating a welfare spiral worsening lameness
Automated lying time sensors provide farm-level data enabling welfare management

Welfare Considerations

Lying time is simultaneously a welfare outcome measure and a driver of further welfare problems. Cows forced to stand excessively develop lameness from unrelieved hoof loading on hard surfaces. Lame cows then find lying painful to transition to and from, creating a self-reinforcing welfare deficit. Measuring lying time using automated sensors provides objective data enabling early identification of inadequate resting conditions before welfare is severely compromised. Housing management that ensures adequate cubicle availability, appropriate cubicle design and access to feed while lying directly prevents this welfare cascade.

What You Can Do

Support dairy certification schemes requiring lying time monitoring and minimum standards
Advocate for automated lying time monitoring as a welfare outcome measure in dairy regulations
Choose dairy products from farms with documented lying time management protocols
Support research into the relationship between specific management factors and lying time in dairy systems
