One hundred twenty crossbred steers (450 lb, +/37 lb) were stratified by weight and randomly assigned to one of two feeding blocks. The cattle grazed dormant rangeland for 56 days from October 12 through December 7. Each block was supplemented three times a week with the equivalent of 7 days of dried corn distiller’s grains (DDG) at 0, 0.25, 0.50, or 0.75% body weight (BW)/d on a dry matter bas...

Land degradation of alpine rangeland in Dachigam National Park, Northern India, was evaluated in this study using MODerate resolution Imaging Spectroradiometer (MODIS) land products. The park has been used by a variety of livestock holders. With increasing numbers of livestock, the managers and users of the park are apprehensive about degradation of the grazing land. However, owing to weak infr...

Over more than a century there has been debate about the interactions of kangaroos and introduced domestic stock, especially sheep, in the semi-arid and arid rangelands. The potential for competition between the species is still controversial, with pastoralists generally assuming that exploitative competition is a continuing feature of the rangelands, with competition by kangaroos leading to re...

Herbivory and fire are natural interacting forces contributing to the maintenance of rangeland ecosystems. Wildfires in the sagebrush dominated ecosystems of the Great Basin are becoming larger and more frequent, and may dramatically alter plant communities and habitat. This synthesis describes what is currently known about the cumulative impacts of historic livestock grazing patterns and short...

rangelands are important for plant productivity, livestock production, wildlife,conservation of soil and water resources, and etc. one of the main problem of rangeland isthat has not been used based on its potential that leads to more degradation of rangelands.the purpose of this study was to evaluate the range management capability of badrehregion in ilam province, iran, using anp (analytic ne...

The objective of this paper is to examine the sustainability of rangeland agriculture (i.e., managed grazing) on a world-wide basis, with a focus on North America. Sustainability is addressed on three fronts: 1) ecological, 2) economic, and 3) social acceptance. Based on previous and on-going research, we suggest that employment of science-based rangeland grazing management strategies and tacti...

Economists have argued that commonly held African rangelands are suffering widespread degradation due to overstocking. However, in many areas, degradation is localized rather than widespread. Current common property models are insufficient for analysis of such degradation. A model is developed identifying conditions leading to spatial differences in rangeland condition. Analysis of longitudinal...

quality of life measures can provide an important source of medical information for promoting the health status of chronically ill patients. the purpose of the present study was to evaluate health related quality of life in psychiatric veterans of the iraq- iran war of the 1980s.they were out patients diagnosed with various psychiatric symptoms. the present study used a cross sectional design, ...
