Animal waste from concentrated swine farms is widely considered to be a source of environmental pollution, and the introduction of veterinary antibiotics in animal manure to ecosystems is rapidly becoming a major public health concern. A housefly larvae (Musca domestica) vermireactor has been increasingly adopted for swine manure value-added bioconversion and pollution control, but few studies ...

This chapter considers the emissions of ammonia (NH 3) and nitrous oxide (N 2 O) from the excreta of agricultural animals deposited in buildings and collected as either liquid slurry or solid manure. This includes emissions from animal excreta at all stages: animal housing, manure storage and from land spreading of manures. Excreta deposited in fields by grazing animals are dealt with under SNA...

California's dairies are the largest confined animal industry in the state. A major portion of these dairies, which have an average herd size of nearly 1000 animal units, are located in low-relief valleys and basins. Large amounts of liquid manure are generated and stored in these dairies. In the semi-arid climate, liquid manure is frequently applied via flood or furrow irrigation to forage cro...

As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental impacts of egg production systems and identified topics requiring further research. Currently, we know that 1) high-rise cage houses generally have poorer air quality and emit more ammonia than manure belt (MB) cage houses; 2) manure removal frequency in MB...

With approximately 696 million tons of animal manure produced yearly in the United States, and 46% of that being generated on concentrated animal feeding operations (CAFOs) (Ribaudo et al., 2003), animal waste management is becoming an important environmental concern. It causes air and water quality concerns and climate impacts. In addition, many CAFOs generate more waste than can be disposed o...
