In October 2002, the United States Department of Agriculture issued the framework for the National Organic Program.

There is currently a great demand to find not only organic substances to use as feed additives but also alternative treatment methods for common poultry diseases. This article is intended as a brief introduction to the research presently being pursued to develop suitable additives and treatments for this rapidly growing sector of the food industry.
