Comparative aspects of foraging behaviour of pronghorn antelope and cattle.
Abstract
On shortgrass prairie in N.E. Colorado with dominant Bouteloua gracilis, Buchloe dactyloides, Agropyron smithii and Artemisia frigida, antelope and cattle consumed a similar range of foods in winter, with 5 species comprising 94% of antelope and 96% of cattle diets. In summer, B. gracilis accounted for >50% of the diet of cattle whereas antelope diets were mixed, with 18% Sphaeralcea coccinea the most abundant item.
