Alfalfa Grazing Management
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...
متن کاملA degree-day model of sheep grazing influence on alfalfa weevil and crop characteristics.
Domestic sheep (Ovis spp.) grazing is emerging as an integrated pest management tactic for alfalfa weevil, Hypera postica (Gyllenhal), management and a degree-day model is needed as a decision and support tool. In response to this need, grazing exclosures with unique degree-days and stocking rates were established at weekly intervals in a central Montana alfalfa field during 2008 and 2009. Anal...
متن کاملComparisons of Cattle Grazing and Sheep Grazing
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...
متن کاملCorn supplementation of lambs grazing alfalfa.
We investigated the effects of supplementing Rambouillet x Suffolk wether lambs grazing irrigated 'Cimarron' alfalfa (Medicago sativa L.) with three levels (0 [C0], 123 [C123], and 247 [C247] g of DM.lamb-1.d-1) of cracked corn. Each treatment group also received 190 g of a supplement designed to prevent bloat. Replicated pastures (three per treatment) grown on a fine, mixed, thermic Torretic P...
متن کاملIdentification of seedling cabbages and weeds using hyperspectral imaging
Target detection is one of research focuses for precision chemical application. This study developed a method to identify seedling cabbages and weeds using hyperspectral imaging. In processing the image data with ENVI software, after dimension reduction, noise reduction, de-correlation for high-dimensional data, and selection of the region of interest, the SAM (Spectral Angle Mapping) model was...
