Technologies to mitigate the environmental impact of broiler production

Abstract

The broiler industry produces efficiently animal protein, but generates residues with high contents of N, P, K, trace minerals, and high bacterial charge. The rapid microbial decomposition of these residues cause ammonia volatilization, nuisance odor, fine particulate matter, and attract insects and rodents. This presentation will discuss the more effective methods to utilize these resources and minimize potential environmental impact. These procedures include planning, personnel training, zoning of areas used to dispose the final residues in crop lands, farm isolation, precision nutrition, litter and house management practices, and appropriate mortality disposal. Broiler litter has been used for animal feeding and power generation. Additionally, new technologies to reduce ammonia, odor and fine particle emissions, or reduction of P solubility will be presented.
