Salmonella is a foodborne pathogen generally associated with mild to moderate self-limiting gastroenteritis. In the United States the incidence of salmonellosis (16.37 cases per 100,000 population/ year) ranked highest among the pathogens tracked by FoodNet in 2012 (CDC, 2014). Furthermore, invasive infections accounted for 5% of the reported salmonellosis cases during 1996-2006 (Jones 2008). W...
Livestock production is a major consumer of fresh water, and the influence of livestock production on global fresh water resources is increasing because of the growing demand for livestock products. Increasing water use efficiency of livestock production, therefore, can contribute to the overall water use efficiency of agriculture. Previous studies have reported significant variation in livesto...
the first motive for the determination and evaluation of an energy productionsystem is the need to change. such system is dynamic in nature and is influenced bymany factors such as age and physiological status of individual sheep or goat, quantityand quality of available feed and environment including the management systems.traditional pastoral resource assessments do not always account for the...
Buffalo livestock plays a central role in the regional economy in some areas of southern Italy, through the production of mozzarella cheese. With about 250,000 heads per utilizable agricultural area (equal to 107,400 ha), livestock husbandry is intensive. An important issue with regard to high animal density is manure management, an activity determined by cost optimization and the laws governin...
This study identified different roles played by urban household members in livestock production in Southeast Nigeria. Data were collected from two hundred and ten (210) livestock keepers using interview schedule. The data obtained were analyzed using descriptive statistics. The mean age of the farmers was 49.1 and a majority (86.7%) had at least primary education. A greater proportion (78.1%) o...
Riparian meadows occupy a small proportion of the public lands in the western United States but they provide numerous ecosystem services, including the production of high-quality forage for livestock grazing. Modern conservation management strategies (e.g., reductions in livestock stocking rates and adoption of new riparian grazing standards) have been implemented to better balance riparian con...
Managing the environmental risk associated with livestock production is a significant challenge. Nitrogen and phosphorus are commonly implicated as the sources of ground and surface water quality problems associated with livestock production. The degree of imbalance between these nutrient inputs and the managed nutrient outputs for a livestock operation defines the magnitude of potential enviro...
