Effect of Grazing Pressure on Cattle Grazing Cool Season Annual Forages
… understanding of specific plants selected by grazing ruminants remains elusive. Many long- and short-term factors impact cattle grazing behavior. Ultimately, grazing behavior can affect forage available for grazing, nutrient density of forage, dry matter intake, and animal performance. A …

Grazing angle neutron diffraction
… development and practical implementation of grazing-angle neutron diffraction as a new method of non-destructive surface and interface analysis. Diffraction in the grazing-angle geometry with x rays and neutrons possesses two unique advantages over specifically surface-sensitive methods for …

Grazing impacts on sediment production and runoff from single and mixed species grazing
… for the mixed and single species grassland grazing will be examined. Mixed species grazing refers to cattle and sheep grazing concurrently in the same area; while single species grazing refers to cattle grazing alone. Understanding the environmental effects of mixed grazing as compared to a …

Effect of Time of Supplementation on Performance and Grazing Behavior of Grazing Steers
Beef cattle follow a daily, cyclical pattern of grazing, rumination, and digestion that coincides with their environment and season. Traditionally backgrounding operations hand feed any supplement in the morning. However, this practice may interrupt typical grazing patterns during early morning and …

Grazing in the urban environment : An economic and social appraisal of conservation grazing schemes.
This study aims to examine the use of grazing livestock to manage urban and urban fringe sites of conservation interest. It considers in particular, the way that organisations achieve grazing and the cost-effectiveness of grazing in comparison with cutting. The latter is a method often advocated as …

Grazing and Range Management - Alberta
Livestock grazing and range management have had major impacts on grassland vegetation in Alberta. Grazing animals have had impacts on plant communities in Alberta since before fur traders occupied the land. Over the years both livestock and wildlife have been studied and managed to try and ensure …

Human-Managed vs. Natural Grazing Systems: Exploring Effects of Livestock and Wildlife Grazing at Multiple Scales
<p>Grazing by large herbivores is the most prevalent land use on grassland ecosystems, which cover greater than 40% of the earth's land surface and provide critical ecological and economic benefits. As such, understanding how grazing impacts different aspects of the ecosystem is of especially great …

The grazing habits of cattle on pasture
… 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 production. …

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 …

Grazing Behavior of Beef Steers Grazing Endophyte-Infected, Endophyte-Free, and Novel Endophyte Infected Tall Fescue, and Lakota Prairie Grass
… concern. Producers need alternative forages for grazing cattle that do not have this negative aspect. The objective of this experiment was to determine the grazing behavior of cattle grazing Lakota (L) prairie grass (Bromus catharticus Vahl.), endophyte infected (E+), endophyte free (E-), and …

Differential dry matter production, nutritive value and grazing utilisation of perennial ryegrass varieties and mixtures evaluated within intensive grazing regimes
… profit. Perennial ryegrass (Lolium perenne L.) grazing efficiency has been shown to influence farm herbage utilisation. <br/><br/>The objective of this thesis was to develop a methodology for the evaluation of perennial ryegrass variety grazing efficiency. Such evaluation data could then be …

Comparison of buffered grazing systems for beef cattle
… productivity of a rotational versus continuous grazing system for beef production within a buffer grazing system, thirty crossbred beef cows and their calves were randomly assigned to one of two grazing systems replicated twice over three years of the experiment. Each replication of the …

Evaluation of the Persistence of Grazing Alfalfa Varieties
<p>The use of alfalfa (Medicago scitiva L.) for grazing is becoming more common. Alfalfa is the most widely planted legume, and is one of the most nutritional forage crops available. It is proposed that alfalfa was cultivated 4000 to 5000 years ago and produces the most protein per acre of any …

Grazing and Feeding Management of Lactating Dairy Cows
Two studies were conducted during the grazing season of 1997. Study 1 consisted of three Experiments, and the objectives were to compare milk production and composition, body weight change and body condition score, and to determine time patterns of grazing between cows supplemented with different …

Effects of Phosphorus Supplementation on Grazing Beef Cattle
… to supplementing various levels of mineral P to grazing beef cattle. A producer survey and a research trial were conducted to examine the effects of supplementing mineral phosphorus (P) to grazing cattle. In the first study, mineral tags, producer surveys, and fecal, forage, and soil samples were …

Grazing and Climate Effects on High Elevation Meadow Resources
… to understand how intensity and timing of grazing affect the temporal availability of mesic commodities utilized by species like sage-grouse. This dissertation quantifies changes in the timing of availability of mesic sage-grouse resources across grazing and climatic gradients in …
