Herbage Disappearance and Grazing Capacity Determinations of Southern Pine Bluestem Range

Abstract

Herbage disappearance per animal unit day in yearlong grazing on southern pine range averaged 38, 47, and 38 pounds on lightly, moderately, and heavily grazed range. Cattle intake accounted for only 36 to 47% of the disappearance; factors such as trampling, weather, and wildlife accounted for more than 50%. To sustain light, moderate, and heavy grazing intensities yearlong, about 115, 100, and 70 pounds of herbage were required per animal day. Seasonal grazing only required 75 and 40 pounds for moderate and heavy stocking.
