Kansas State University Agricultural Experiment Station and Cooperative Extension Service Previously, the release of Conservation Reserve Program (CRP) acres for emergency haying and grazing was a result of drought conditions. Under new program rules, haying and grazing is now allowed on eligible acres regardless of moisture conditions under managed haying and grazing. Managed haying and grazin...
Livestock face complex foraging options associated with optimizing nutrient intake while being able to avoid areas posing risk of parasites or disease. Areas of tall nutrient-rich swards around fecal deposits may be attractive for grazing, but might incur fitness costs from parasites. We use the example of dairy cattle and the risks of tuberculosis transmission posed to them by pastures contami...
Reintroduction of fire and grazing, alone or in combination, has increasingly been recognized as central to the restoration of North American mixed-grass and tallgrass prairies. Although ecological studies of these systems are abundant, they have generally been observational, or if experimental, have focused on plant species diversity. Species diversity measures alone are not sufficient to info...
This paper reviews current knowledge of the social behavior of grazing beef cattle and discusses how that knowledge can be applied to rangeland cattle management. Cattle herds are composed of social subgroups that influence grazing distribution on rangeland. Grazing distribution is, in part, a learned response; therefore, management strategies that alter the social composition and structure of ...
Livestock grazing can be used as a key management tool for maintaining healthy ecosystems. However, the effectiveness of using grazing to modify habitat for species of conservation concern depends on how the grazing regime is implemented. Timing of grazing is one grazing regime component that is less understood than grazing intensity and grazer identity, but is predicted to have important impli...
Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements. A change from sheep grazing to cattle grazing can cause a rapid deterioration in pasture production, w...
Global food demand is growing rapidly. Livestock grazing can provide a valuable source of protein, but conventional grazing is often unsustainable. We studied an 800,000-ha section of a threatened ecoregion in southeastern Australia. Conventional management in the region involves continuous livestock grazing with few rest periods and regular fertilizer application. By using remotely sensed data...
Grazing alfalfa with dairy or beef animals is not a common practice in California or even in the United States. Although a limited number of alfalfa acres are grazed in the humid Midwest and East, it is rare in the West, and the ruminant alfalfa forage systems throughout the United States consist of hayand haylage-based harvest methods. However, there is increased interest in grazing in North A...
In grazing systems, heterogeneous distributions of forage resources and faeces result in localised accumulations of nutrients and parasites (both macroparasites and microparasites), creating trade-offs between the costs of exposure to infestation or infection and the benefits of nutrient intake. Each contact between livestock and faeces in the environment is a potential parasite/pathogen transm...
Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop management. The gr...
