Dairy Cow Lying Behaviour and Welfare

Lying time is one of the most important and sensitive welfare indicators in dairy cattle. Cows have a strong motivation to lie down for 10-14 hours per day, and restriction of lying time causes measurable stress and physical harm.

Key Facts

Dairy cows are highly motivated to lie down and will accept electric shocks to access lying areas after deprivation, demonstrating the priority they place on this behaviour
Cows prevented from lying for more than 2-3 hours show altered gait, increased cortisol, and compensatory lying behaviour when given access
Average lying time in commercial dairy farms ranges from 9-13 hours per day, with cows in poorly designed or overcrowded cubicle systems lying significantly less
Stall design critically affects lying time — cubicles that are too small, too short, or have inadequate bedding cause avoidance and reduce lying behaviour
Time spent in parlour holding areas waiting for milking can significantly reduce daily lying time, particularly in large herds with long milking queues

Welfare Considerations

Lying time is valuable as a welfare indicator because it integrates multiple welfare dimensions: a cow that lies for adequate time has appropriate physical comfort, sufficient space, a suitable substrate, and is not chronically ill or lame. Conversely, reduced lying time indicates welfare compromise from one or more causes. The strong motivation to lie is not merely preference but a physiological necessity — prolonged standing causes hoof and leg problems, and the physical recovery that occurs during lying is essential for musculoskeletal health. Welfare assessment on dairy farms should include lying time measurement using data loggers as a routine indicator, with investigation triggered when average lying time falls below 10 hours per day. Management interventions including stall redesign, reduced overcrowding, and bedding improvement consistently increase lying time and improve associated welfare outcomes.

What You Can Do

Support dairy welfare schemes that include lying time monitoring using data loggers as a routine welfare outcome measure
Choose dairy products from farms with documented low lameness prevalence and good housing design standards
Advocate for dairy farm welfare assessments to include cubicle design audits and lying time measurement
Support research into low-cost lying time monitoring technologies that make widespread welfare monitoring feasible
Reduce dairy consumption where possible and prioritise higher-welfare dairy products when purchasing
