Cattle lying time is a sensitive welfare indicator — restricted lying opportunity causes stress, musculoskeletal pain and reduced welfare across all production systems.
Dairy cows that cannot lie comfortably for sufficient time experience chronic stress, musculoskeletal pain and impaired health. Cubicle design, bedding depth and cleanliness all affect lying comfort and duration. Cows that avoid stalls due to discomfort and stand on concrete instead are at higher risk of lameness. Lying time monitoring is a practical, automatable welfare indicator for precision dairy farming systems.
