摘要: This research measured steer gains, aboveground biomass remaining at the end of growing season, and economic returns tallgrass prairie grazed under season-long stocking (SLS-C) a grazing system that included 2-yr rotation SLS-rotated (SLS-R) intensive early (IES; 23normal rate)þlate-season normal rate (IESþLSGR). We hypothesized even though on IESþLSG-R pasture was above recommended rate, greater regrowth availability in late season would result steers gaining as well or better than those stocked SLS rate. By rotating IESþLSG treatment with over 2 yr, we anticipated productive capacity be restored one season. Further, increased increase net profit. Comparing traditional to system, which
