Effect of different air speeds at cow resting height in freestalls on heat stress responses and resting behavior in lactating cows in Wisconsin.

Heat abatement (e.g., soakers, fans) effectively reduces the negative physiological and production effects of heat stress, but no previous studies have documented effective interventions for the reduced lying times observed in response to hot weather.

Ventilation Systems for Adult Dairy Cattle.

Ventilation systems for adult dairy cattle can be divided into natural and mechanical systems. Mechanical systems include tunnel and cross ventilation. Hybrid systems incorporate both mechanical and natural ventilation design elements.
