    Introduction CHARLES G. DURBIN AND JOHN H. COLLINS Veterinary Medical Branch, Division of Medicine, Food and Drug Administration, Department of Health, Education, and Welfare Washington, D. C. There is remarkably widespread recognition of the fact that the American farmers face profound changes in feeding and medicating livestock and poultry. These changes are the direct result of modern discoveries concerning nutrition, disease control, and the availability of many new drugs for animal use. The prevalence of animal disease is an important limiting factor in the livestock industry of any country. Failure to develop and maintain adequate disease control measures can lead to heavy annual loss of livestock resources and contribute to high production costs, which in turn may seriously affect the general economy and welfare of a nation. Anyone who keeps livestock on a small or large scale may confidently expect to profit by applying modern feeding methods and disease prevention practices in his daily farm operations. This inevitably leads to the use of drugs in feeds. It is reported that more than half the feed-lot cattle in this country are now getting diethylstilbestrol in their feeds to increase weight gains, just one year after the introduction of this new use of the drug. Furthermore, enough antibiotics were sold last year to medicate three fourths of all manufactured feeds. Because of this unprecedented increase in the use of drugs in animal feeds, it was deemed advisable to bring together a group of people interested in medi- cated feeds to discuss the mutual problems. This thinking was further precipitated by the increased volume of questions received by the Veterinary Medical Branch, Division of Medicine, Food and Drug Administration, regarding the addition of drugs to feeds. When drugs are added to animal feeds for the prevention and treatment of various diseases and/or for promoting growth, such articles become drugs as defined by the Federal Food, Drug, and Cosmetic Act. This has created many new problems for feed manufacturers, drug manufacturers, and regulatory officials. The following general outline was used in formulating the program for the Symposium on Medicated Feeds: I. History and general remarks. II. Types of medicated feeds. III. The pharmacologic aspects of medicated feeds. IV. Assay and mixing problems involved in the manufacture of medicated _ feeds. V. Public health significance.
