Dairy Grazing: Selecting the Right Forage

Big bluestem (Andropogon gerardii Vitman)

Warm-season grasses

Big bluestem used to be the dominant grass in the native prairies of Missouri. Today, this perennial warm-season bunchgrass is used for forage and wildlife habitat. Big bluestem grows statewide, and it is currently found on about 1 million acres in Missouri. It produces good quality hay and will persist indefinitely if properly managed. It is both winter- and drought-hardy and does better in poorly drained soils than some other warm-season grasses. It is also compatible with many other forage species. However, it is slow to establish, and thus weeds can make establishment a problem. It works well in a planned grazing system if it is not allowed to become mature before grazing and if a 6-inch or greater stubble height is maintained to encourage regrowth.
