dc.description.abstract A survey of Oregon sheep producers conducted as part of this research, indicated that lambing losses by sheepgrowers in winter rainfall areas of Oregon currently average 16 percent. The majority of the lambs born in these areas are born in pastures without the benefit of shelter. The utilization of portable pasture shelters with wooden slat floors by lambing ewes was evaluated. The study measured occupancy rates of two shelters under free choice, winter rainfall pasture conditions. Occupancy (sheltering) rates were determined from the number of ewes or lambs in a shelter, and were measured through the use of time lapse photography. The averages of daily maximum sheltering percentages for ewes and lambs were 31.2 and 50.7 percent, respectively. At least one ewe lambed by choice in a shelter on the slatted floor. The use of portable pasture shelters with slatted floors could reduce the lamb losses experienced by winter rainfall pasture lambing operations. en_US
