Dairy Cow Comfort and the Welfare Importance of Lying Time

Dairy cows need to lie down for 10 to 14 hours per day to maintain health and welfare, yet many commercial housing systems restrict lying time through inadequate stall design and overcrowding.

Key Facts

Dairy cows deprived of lying time show elevated stress hormones and increased rates of lameness within days
Cubicle stalls that are too short, too narrow, or poorly bedded cause cows to stand awkwardly or avoid lying down
Cows lying on rubber mats compared to bare concrete show lower lameness rates and longer daily lying times
Time spent in milking parlour queues can reduce lying time by 2 to 4 hours per day in large herds
Deep-bedded straw yards, while harder to manage, consistently produce the best lying comfort outcomes in welfare assessments

Welfare Considerations

Lying time is one of the most sensitive indicators of dairy cow welfare and one of the most easily measured. Cows are highly motivated to lie down, and when prevented from doing so, they become increasingly stressed and their health deteriorates rapidly. The design of resting areas is therefore a critical welfare determinant in dairy systems. Cubicle dimensions, neck rail position, kerb height, and bedding depth all influence whether cows choose to lie in stalls or stand in uncomfortable compromises. Regular assessment of lying time using accelerometer leg tags is now affordable and provides continuous welfare monitoring data that allows early intervention before problems escalate.

What You Can Do

Support dairy welfare standards that require minimum daily lying time monitoring and targets
Ask dairy farmers and retailers about their cubicle design and bedding standards
Choose dairy products from schemes that include housing welfare assessments
Advocate for mandatory lying time monitoring in dairy farm certification programmes
Support research into affordable lying time monitoring technologies for smaller dairy operations
