Authors compared short duration grazing by sheep, in early and late spring, at different stocking intensities. Average daily forage disappearance was higher in the 10-day treatment than the 2-day one, but this higher forage intake was offset by a larger amount of forage destroyed by each ewe under the low stocking density (10-day treatment). Percent of tillers grazed was higher under 10-day than 2-day treatment. Lower selectivity for subclover (Trifolium subterranum) than tall fescue (Festuca arundinacea) indicate a more uniform distribution of grazing in the 10-day treatment. For this area, a 10-day rotation was more efficient than 2-days in a short duration grazing system.
