Livestock Responses To Complementary Forages In Shortgrass Steppe, Justin D. Derner, Richard H. Hart

Great Plains Research: A Journal of Natural and Social Sciences

Livestock gains of yearling Hereford heifers were evaluated during 1996–1999 on two complementary forage grasses, “Bozoisky-Select” Russian wildrye (Psathyrostachys juncea [Fisch.] Nevski) or “Hycrest” crested wheatgrass (Agropyron cristatum [L.] Gaertn. ssp. desertorum [Fisch. ex Link] A. Love). Average daily gains were similar between light and moderate stocking rates for both Bozoisky and Hycrest, and gains trended higher for Hycrest than for Bozoisky at light stocking rates. Total annual (spring + fall) beef production (kg/ha) was consistently greater for moderate (29%–46%) than for light stocking of both complementary forages. Spring gains represented >75% of the total annual beef production …
