Despite overall increased production in the last century, it is critical that grazing production systems focus on improving beef and dairy efficiency to meet current and future global food demands. For livestock producers, production efficiency is essential to maintain long-term profitability and sustainability. This continued viability of production systems using pasture- and range-based grazi...
the obstacles towards this pursuit not only negatively affect the views and perceptions of the forest villagers about forest resources but also, from time to time, causes turkey, which has the appropriate environment in terms of livestock, to become one of the countries that import meat. in this study, the perception and views of hair goat breeders about forestry & livestock breeding relati...
Quantitative study of species diversity across different land use units and districts is important to document status of local plant biodiversity, to evaluate impact of management and for planning future management. This study aimed at determining impacts of land use units on species diversity and spatial distribution of species in two districts of Borana zone, Oromia, Ethiopia. Stratification ...
Logging and livestock grazing are widespread management practices in Southwestern ponderosa pine forests that may act either independently or synergistically with fire management to influence habitat availability and use, reproductive success, and songbird population levels. Fire, historically an important natural process in Southwestem ponderosa pine forests, had far-reaching affects on forest...
The intensity of management of lowland grassland fields in the United Kingdom, coupled with the fact that such grasslands dominate much of the lowland landscape, means that there are now few opportunities for many plants, invertebrates, birds, or mammals to survive. The Scottish Agricultural College (SAC) has investigated whether fencing off the margins of such fields next to watercourses to co...
Rising temperatures due to climate change are pushing the thermal limits of many species, but how climate warming interacts with other anthropogenic disturbances such as land use remains poorly understood. To understand the interactive effects of climate warming and livestock grazing on water temperature in three high elevation meadow streams in the Golden Trout Wilderness, California, we measu...
Y the turn of the century, the Edwards Plateau region of Texas had developed into a major livestock area (27). Continuous, heavy grazing by domestic livestock and the prevention of natural fires since that time have significantly changed the vegetative complex (15, 16). Long-term, excessive removal of vegetation on the plateau by grazing animals reduced the protective herbaceous cover, broke do...
Ruminant livestock provides meat and dairy products that sustain health and livelihood for much of the world's population. Grazing lands that support ruminant livestock provide numerous ecosystem services, including provision of food, water, and genetic resources; climate and water regulation; support of soil formation; nutrient cycling; and cultural services. In the U.S. southern Great Plains,...
