Medicated Feed Additives and Other Regulated Ingredients Module

Adam Fahrenholz

The module for medicated feed additives and other regulated ingredients cover: the classification structures for medicated additives and medicated feeds, the identification of other regulated ingredients, and the roles of current good manufacturing procedures, or cGMPs, in both feed safety and hazard prevention. This grain module is brought to you by the Iowa Grain Quality Initiative, and was produced by the former Crop Adviser Institute.

Learning objective: Describe the classification structures for medicated additives and medicated feeds, and the roles of current good manufacturing procedures, or cGMP’s, in both feed safety and hazard prevention.

Introduction: A major consideration in feed manufacturing is proper use and documentation of regulated feed ingredients and additives. There are cGMP regulations for medicated feeds. The purpose of the cGMPs is to promote both the consistency and quality of the medicated feeds. cGMP for non-medicated feeds take effect in September 2016.

Additives: Medicated feed additives are fed to animals for nutritional purposes, medicinal purposes, to prevent, treat, or control bacterial infections, coccidiosis, and worms, and to prevent mortality. Overall, they are used to improve the health and productivity of animals.

Classification: Medical feed additives are classified by type; A, B, or C, and category; I or II. The type refers to the usage of medicated feed. Type A medicated additives are referred to as drug premixes and are used to create Type B or C. Type B medicated additives create a medicated supplement that can be mixed to create Type C. Type C medicated additives are fed as complete feeds directly to the animal. Categorization of medicated feed additives is based on preventing drug residues in processed animal tissues after a withdrawal period. Category I are additives that do not require a withdrawal period. Category II are additives that do require a withdrawal period.
