The importance of poultry production worldwide is underscored by this statistic: poultry meat represents almost one-third of meat produced and consumed globally. Moreover, egg production, on a weight basis, is almost 80% that of poultry meat production. This was addressed in a previous editorial (Scanes, 2007b). The basis for the increasing importance of poultry worldwide has been research on g...

I read with great interest Schmidt’s article on hog feces that was widely spread by Hurricane Floyd flooding in North Carolina (1). Should not all fecal matter, whether human, hog, poultry, or cattle, be held to the same standard of disposal? Why should municipalities be held to a higher level of waste purification for human fecal matter? Sheldon B. Cohen Psychiatrist (private practice) Atlanta...

The purpose of this study was to determine the effect of animal waste loading rates on P adsorption-desorption characteristics of two soils. In a laboratory incubation study, Norfolk soil was treated with beef, poultry, or swine wastes; and allowed to decompose under optimum moisture conditions for a period of 30 days. Phosphorus adsorption-desorption characteristics of the soil were measured a...

Keratinolytic microorganisms have become the subject of scientific interest due to their ability to biosynthesize specific keratinases and their prospective application in keratinic waste management. Among several bacterial classes, actinobacteria remain one of the most important sources of keratin-degrading strains, however members of the Micrococcaceae family are rarely scrutinized in regard ...

Salmonella is a major food-borne pathogen worldwide, including Thai- land, and poultry meat plays a role as a vehicle for the spread of the disease from animals to humans. The prevalence and characteristics of Salmonella isolated from 41 small scale poultry slaughterhouses in Chiang Mai, Thailand were determined during July 2011 through May 2012. Salmonella's prevalence in live poultry, car- ca...

Ammonia emissions are associated with many agricultural operations including animal and poultry operations, waste and wastewater treatment operations, and fertilizer and manure land applications. The fate of ammonia released to atmosphere is affected by interaction with other gases, aerosols, and fine particles. These interactions affect the gas-to-particle conversion. This process alters ammon...

s of papers 47 follow manner. Rules for Animal Feeding Operations have been recently enforced and will require adoption of appropriate Best Management Practices (BMP’s), which includes Nutrient Management Planning for all operations where animals are raised in confinement according to regulatory definition. Nutrient management is necessary for agricultural production systems to protect air, soi...
