Rotational Grazing and Greenhouse Gas Reductions: A Case Study in Financial Returns
… GHG sequestration is an intensively managed rotational grazing system. The objective of this study is to estimate potential financial returns from conversion to rotational grazing and the sale of GHG credits by Virginia beef and dairy farms. The three GHGs examined in the study are carbon …

Passerine Use of Grasslands Managed With Two Grazing Regimes on the Missouri Coteau in North Dakota
Several rotational grazing systems have been implemented on the Missouri Coteau in central and northcentral North Dakota as part of the Prairie Pothole Joint Venture (PP N). The impacts these systems have on grassland passerines are not fully understood. Objectives for this study include …

Modelling the influence of rainfall variability and different grazing systems on the spatiotemporal dynamics and productivity of semiarid rangeland
… system dynamics; and secondly, to re-examine the rotational grazing system with modelling as a substitute to field trials.

Managing herbivory over space and time: consequences for vegetation and cattle responses in African rangelands
… remains unclear. Previous research on forms of rotational grazing management are criticized for being limited to small-scale experimental trials that make untested assumptions about the effect of grazing density on animal behaviour and neglect measurements of landscape-scale pattern and process. …

Assessing Rodent Species Counts and Diversity in the Not-Grazed Montana De Oro State Park and the Rotationally Grazed Pecho Ranch
<p>The available data examining the influence of rotational grazing on rodent responses are limited. This study investigated how rotational livestock grazing practices influence small mammal rodent abundances and species diversity. We looked for evidence of variation in the occurrence and/or …

Effects of Grazing Intensity and Temporal Application of Grazing Treatments on Nongame Birds in North Dakota Mixed-Grass Prairie
Grazing occurred naturally in the northern Great Plains and influenced many natural processes in grassland ecosystems, including the habitat selection of breeding birds. Grazing, mainly for livestock production, is still an important land use practice and is one that impacts millions of hectares on …

Estimating forage yields with simple methods
… on a series of experiments before and after rotational grazing of grass-clover pastures. Visual and Disc methods were also evaluated on experimental plots of ryegrass and bluegrass. Generally, high correlations with actual yield were obtained by all four methods. Correlations with actual …

Autumn performance of rhizomatous clovers after a summer drought, under different grazing treatments
… (Trifolium repens), were evaluated in a sheep grazing trial on a lowland medium fertility soil (Templeton silt loam) at Lincoln University, Canterbury. Each rhizomatous clover cultivar / seed line was sown (March, 1989) in plots with four rows 0.75m apart, 80m long. There were three replicates …

Off-stream water sources for grazing cattle as a stream bank stabilization and water quality BMP
… the installation of off-stream water sources for grazing cattle as an alternative to stream bank fencing. The study was located on two commercial cow-calf operations in southwest Virginia which utilized rotational grazing. The presence of an off-stream water source for grazing cattle greatly …

Revisiting Aldo Leopold's "Perfect" Land Health: Conservation and Development in Mexico's Rio Gavilan
… eco-tourism, forest density reduction, and rotational grazing, were assessed for feasibility. Recent critiques of Leopold's land ethic were also reviewed. Results indicate most pre-1940s impacts were light, current land health status is moderate, and local interest exists in restoring land …

The grazing habits of cattle on pasture
… the value of species, mixtures, methods of rotational grazing, and continuous grazing of one mixture as compared with grazing different mixtures in a rotational sequence. Data are being obtained on carrying capacity, livestock gains, carcass characteristics, palatability, and rate of milk …

Management of Katahdin Hair Sheep
… pastures were allocated randomly to 1 of 2 grazing treatments: 1) Continuous; or 2) 4-cell rotation. Fifty yearling Katahdin ewes (53 ± 0.7 kg initial BW; 3.3 ± 0.09 initial BCS) were stratified by BW and BCS and allocated randomly to pastures in early May. Grazing d, basal cover, forage …

The Cattle Dung Arthropod Community in Eastern South Dakota: Their Colonization, Impact on Degradation, and Response to Rangeland Management
<p>Cattle grazing operations are an important industry throughout the world and a vital component of the economy of the Northern Great Plains. Rangeland management is important to ensure that cattle grazing remains not only profitable but also environmentally sustainable. Conventionally managed …

Phosphorus runoff potential of different sources of manure applied to fescue pastures in Virginia
… boxes were used to simulate management intensive rotational grazing. Commercial fertilizer TSP and manure application increased runoff TP concentration from 0.146 mg/l to 0.245 mg/l and DRP concentration from 0.105 mg/l to 0.183 mg/l. Runoff P did not differ between organic or inorganic P …
