Delayed winter supplemental feeding and year-round mineral supplementation of beef cows on native range
Polled Hereford cows on native Flint Hills pasture not supplemented until February lost more weight from December to February, lost less from February to May, and were in poorer condition before calving than cows supplemented beginning in November. But calf survival, birth weight, and calf average daily gain were similar for both groups. Feeding cows a calcium, phosphorus, trace mineral mix did not improve any measure of cow or calf performance
Response of yearling steers to burning and fertilizing pasture and intensive early season stocking (bluestem pastures)
Nine pastures totaling 492 acres were summer grazed by yearling Hereford, Hereford-Angus cross, and Angus steers distributed equally by breed. Five pastures were burned April 22, 1975; four were not burned. Burned and nonburned pastures had 0, 40, or 80 lbs. of nitrogen per acre applied aerially April 29, 1975. Stocking rates were determined with herbage production data from experimental plots under similar treatments. Under equal fertilization and stocking ratios, burned and fertilized pastures produced as much or more average daily gain and more gain per acre than nonburned pastures. Fertilizing and heavier stocking tended to reduce average daily gains but increased gains per acre. Steers on the early season, intensely-stocked pasture gained the most per day (1.78 lbs.) and produced the highest gain per acre (70 lbs.)
Increasing levels of grain supplementation for intensive-early stocked steers: three-year summary
During the initial 3 years of a 4-year
experiment, average daily gain tended to
increase in direct proportion to increasing levels
of grain sorghum supplementation (2.3, 2.5 and
2.7 lb gain per day for the control and 2 and 4
lb supplement per day, respectively). The
amount of grass remaining in the pastures at the
end of the growing season (October 1) was
greater in each of the 3 years when cattle were
supplemented at 4 lb/day. During the 2 years
(1989 and 1990) that feedlot performance was
monitored, level of supplementation for grazing
steers did not influence subsequent feedlot gain
or efficiency

Effect of Cages on Herbage Yield in True Prairie Vegetation
Forage production under cages in True Prairie vegetation was 640 lb/acre greater than in uncaged areas in ungrazed pastures. Differences were higher on ordinary upland than on limestone breaks range. Weed herbage production was not changed by caging.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Steer gains on burned and nonburned bluestem pasture, 1978 to 1982
From 1978 to 1982, steers on a late spring burned pasture averaged 40 lbs more gain each summer than steers on a non-burned pasture
Effects of grazing system and use of a pasture-phase implant on grazing and finishing performance of steers
Results are presented from the first year
of a 2-year study to evaluate the effects of
grazing system (intensive-early stocking or
IES vs season-long grazing or SLG) with or
without a pasture-phase implant (Synovex-S®)
on grazing and subsequent finishing
performance. Compared to a SLG system,
IES resulted in faster rate of gain on pasture
and more beef produced per acre, although
SLG resulted in greater total pasture gain per
animal. Implanting improved rate of gain
and increased beef per acre, particularly for
IES steers. In the feedlot, IES steers gained
weight faster and more efficiently than SLG
steers. However, SLG steers had greater
final live weights and carcass weights at a
common backfat thickness . Pasture-phase
implanting did not affect feedlot
performance. For heavier SLG steers, final
feedlot weights combined with a higher
proportion of total gain being made on pasture
offset their slower gains and higher cost
of production. Implanting IES steers prior to
grazing resulted in a numerical improvement
in final feedlot weight and net return
Comparison of Season-Long Grazing Applied Annually and a 2-Year Rotation of Intensive Early Stocking Plus Late-Season Grazing and Season-Long Grazing
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; 2X normal stocking rate) + late season grazing at the normal stocking rate (IES + LSG-R). We hypothesized that even though the stocking rate on the IES + LSG-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 IES + LSG treatment with SLS over 2 yr, we anticipated that the aboveground biomass productive capacity of the IES + LSG pasture would be restored in one growing season. Further, we hypothesized that the increased stocking rate with IES + LSG would increase net profit. Comparing traditional season-long stocking to the system, which was a combination of SLS and IES + LSG rotated sequentially over a 2 yr period, the system increased steer gains by 7 kg . hd-1 and by 30 kg ha-1, had a consistent reduction of 429 kg ha-1 biomass productivity, and increased net profit by 55.19 per steer and 34.28 per hectare.The Rangeland Ecology & Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Reseeding "Go-Back" Land in the Flint Hills of Kansas
Three sorghum types were compared as mulches for seeding 12 native species and varieties in "go-back" land in the Kansas Flint Hills. Significant differences in seedling establishment were found among the species and varieties, but type of sorghum mulch had no effect.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
