Grazing capacity, sheep gains: Cheatgrass, bunchgrass ranges in southern ID

View article.

Comparisons were made of grazing capacities and sheep gains on both cheatgrass range and on native bunchgrass range during early spring. Capacities were similar on these two range types in wet years, but were almost 60% greater on bunchgrasss range during dry years. Sheep gained an average of 0.32 lb. per head per day over three spring periods on the two vegetation types. In 2 of the 4 study years, they lost weight during the first 2-week grazing period. Sheep gains per acre were similar on the two range types.
