Providing cattle with outdoor pasture access improves welfare through expression of natural behaviors, positive affective states, and reduced stress compared to fully housed systems.
Pasture access represents the gold standard for cattle welfare, enabling expression of natural foraging, social, and exploratory behaviors that generate genuinely positive affective states. The play behavior observed when cattle first access spring pasture after winter housing is a compelling behavioral indicator of positive welfare — animals expressing exuberance in ways impossible in confined spaces. Pasture access also reduces the physical health problems endemic to housed systems including lameness and mastitis. Where year-round grazing is not possible, maximizing the grazing season length provides welfare benefits proportional to the time spent outdoors.
