Description
Diets of four large herbivores grazing together on a shortgrass prairie rangeland were studied. Cattle and bison consumed mainly grasses; sheep and antelope consumed mainly forbs. To maximize forage use, optimal grazing determined by nonlinear programming would be 67, 20, 12, and I% of the forage grazed to be taken by cattle, bison, sheep, and antelope, respectively. Historically, this range has been grazed primarily by cattle. This study suggests more animal production could be attained with a mixture of herbivore species.
