Samenvatting

Cows housed indoors with cubicles are probably more restricted in their choice of lying posture and orientation compared with cows housed on pasture. We therefore studied lying postures on pasture in Uruguay and the Netherlands, and in cubicles in the Netherlands, also recording orientation on pasture in Uruguay and divider and bedding type in Dutch cubicles. Cows on pasture in Uruguay showed more long postures, lying on their belly with the neck stretched, and, per herd, cows preferred a specific lying orientation. Dutch cows on pasture showed more wide postures, lying on their side with three legs stretched, while in cubicles they showed more narrow postures, lying on their side with folded hind legs. Wide postures were seen more in cubicles with mattresses and free-hanging dividers. We conclude that since cows in cubicles show more narrow postures than on pasture and cannot choose lying orientation, their choice in showing preferred behavior is restricted. More research is needed to study the consequences of restricted choice in lying behavior on the health and welfare of dairy cows.
