Poultry litter
From Wikipedia, the free encyclopedia
In agriculture, poultry litter or broiler litter is a mixture of manure, feed, feathers, and the sawdust used as bedding material in poultry farms.
Traditionally used as fertilizer, it is now also used as a livestock feed as a cost-saving measure compared with other feedstock materials, particularly for beef animals.[1] [2]. In 2004, some officials of the U.S. Food and Drug Administration called for a ban on feeding broiler litter to cattle, to combat the spread of bovine spongiform encephalopathy, more commonly called "mad cow disease".[3]
Poultry litter is also now being used in Ireland as a biomass energy source on a small scale. This system uses the poultry litter as a fuel to heat the broiler houses for the next batch of poutry being grown thus removing the need for LPG gas or other fossil fuels.[4]
