Six herds of yearling steers (n=127) will graze native summer pastures from May to August at the Cottonwood Field Station near Philip, South Dakota. Six pastures are divided into two groups: a continuous grazing (CG) treatment with a low, moderate, and high stocking density and a virtually fenced rotational (VFR) grazing system with the same stocking densities. VenceTM virtual fence collars were placed on all animals within the study and collected GPS data at 5-minute intervals. The CG collars are not actively managed. The VFR system is actively managed through the collars and rotated based on the amount of available forage and grazing utilization. Results from this study will analyze daily distance traveled, amount of time spent grazing, grazing distribution and impact on animal behavior between the two systems.
