چکیده انگلیسی
This research measured steer gains, aboveground biomass remaining at the end of the growing season, and economic returns of tallgrass prairie grazed under season-long stocking (SLS-C) and a grazing system that included a 2-yr rotation of SLS-rotated (SLS-R) and intensive early stocking (IES; 2à normal stocking rate)â+âlate-season grazing at the normal stocking rate (IESâ+âLSG-R). We hypothesized that even though the stocking rate on the IESâ+âLSG-R pasture was above the recommended rate, the greater regrowth availability in the late season would result in steers gaining as well as or better than those stocked SLS at the normal rate. By rotating the IESâ+âLSG treatment with SLS over 2 yr, we anticipated that the aboveground biomass productive capacity of the IESâ+âLSG pasture would be restored in one growing season. Further, we hypothesized that the increased stocking rate with IESâ+âLSG would increase net profit. Comparing traditional season-long stocking to the system, which was a combination of SLS and IESâ+âLSG rotated sequentially over a 2-yr period, the system increased steer gains by 7 kgâ·âhdâ1 and by 30 kgâ·âhaâ1, had a consistent reduction of 429 kgâ·âhaâ1 biomass productivity, and increased net profit by $55.19 per steer and $34.28 per hectare.
