Livestock mortalities represent a major waste stream within agriculture. Many different methods are used throughout the world to dispose of these mortalities; however within the European Union (EU) disposal options are limited by stringent legislation. The legal disposal options currently available to EU farmers (primarily rendering and incineration) are frequently negatively perceived on both ...

Livestock production in Vietnam is, as in most Asian countries, increasing rapidly and changing into specialized highly intensified operations. The volume of animal excreta generated exceeds the capacity of the operation land base and cannot be utilized efficiently. As a consequence, there is a loss of plant nutrients from livestock farms that causes environmental pollution. This study carried ...

Fecal wastes from a variety of farmed livestock were inoculated with livestock isolates of Escherichia coli O157, Listeria monocytogenes, Salmonella, Campylobacter jejuni, and Cryptosporidium parvum oocysts at levels representative of the levels found in naturally contaminated wastes. The wastes were subsequently spread onto a grass pasture, and the decline of each of the zoonotic agents was mo...

Excess nutrients shift the ecological balance of coastal ecosystems, and this eutrophication is an increasing problem across the globe. Nutrient levels may be routinely measured, but monitoring rarely attempts to determine the source of these nutrients, even though bio-indicators are available. Nitrogen stable isotope analysis in biota is one such bio-indicator, but across the British Isles, th...

Most of the citrus fruits grown worldwide are oranges of various varieties. More than half of these are processed and have their juice extracted. The resultant wet citrus waste has been used for over 60 years as a source of feed for livestock. Most citrus pulp is now dried for convenience of storage and transport prior to feeding to ruminant livestock. Brazil and the U.S.A. are the largest expo...

The objective of this paper is to summarize the available literature on the concentrations and emissions of odor, ammonia, nitrous oxide, hydrogen sulfide, methane, non-methane volatile organic carbon, dust, and microbial and endotoxin aerosols from livestock and poultry buildings and manure management systems (storage and treatment units). Animal production operations are a source of numerous ...

Greenhouse gas (GHG) emission can become a limiting factor in livestock farming development. Animal manure management systems in Taiwan differ from the model of the Intergovernmental Panel on Climate Change (IPCC) to represent the Far East and Asian region. This study was undertaken to establish GHG production data from anaerobic livestock wastewater treatment processes in Taiwan, and to clarif...

the major purpose of this study was to examine the advantages and implications of biogastechnology in the agriculture sector. biogas is one of many biomass energy sources, which includeanything that was once alive and that can generate energy (except for fossil fuels, which are notrenewable). to talk of biogas is to talk of agriculture, since biogas generation starts withagricultural waste prod...

background :  q fever is a zoonotic disease caused by inhalation of the bacterium coxiella burnetii . ruminant livestock are common reservoirs for c. burnetii , and bacteria present in aerosols derived from the waste of infected animals can infect humans . c. burnetii is thought to infect humans primarily via airborne transmission. methods : 64 environmental swab samples were collected from 24 ...
