摘要

Recent events in the US have brought the issue of phosphorus (P) content in poultry litter to the forefront among legislators, the public, poultry growers, and integrators. In Delmarva, new legislation will limit the use of litter application to soil (based, in part, on soil P content). Given limited land for litter application in certain areas of the U.S.A. where the greatest concentration of poultry production exists today, the poultry industry and poultry producers must find strategies that reduce P in litter with the least impact on income. The challenge of minimizing excreta P is one, that sooner or later, will have to be faced by the poultry industry nationwide. Different strategies exist to reduce excreta P but the most effective strategies will be those that are multi-facetted. Not one single strategy will solve the problem of excess P associated with poultry litter. Pre-and post-production strategies must be integrated if a comprehensive and economically feasible solution is to be found. Pre-production strategies refer to strategies that are implemented before the excreta is generated by the bird. These strategies include feed formulation changes (including use of feed additives, ingredient choices, levels of minerals in the diet), genetic improvements to increase the bird's efficiency of nutrient use, and bird management changes that improve feed efficiency. These pre-production strategies can greatly influence the nutrient content of poultry litter. Post-production strategies refer to strategies that are implemented after the excreta is produced. These strategies include litter treatments that change the solubility of P, composting, shipping litter out of areas with excess soil P, burning poultry litter for fuel, etc.
