• Non-nutritive products added to rations
• Improve efficiency of animal production
• Improvement in intake, digestion, and/or metabolism efficiency and/or health of animal
• Improve manufacture and/or properties of feeds
• Improve consumer acceptance of product
• Added in small quantities
• Utilized extensively in commercial animal production
• Beneficial within modern animal production
• Allow producers to provide safe, wholesome, cost-effective animal products
• Recent years, regulatory agencies and lawmaking bodies began restrict feeding of specific additives
• Factors to consider when determining to use feed additive
• Requirements of animal
• Effects of other components in ration
• Presence of withdrawal period
• Effect of withdrawal period
• Form
• Cost-effectiveness
• In U.S., many additives fed classified as drugs
• Definition of drug, as defined by FDA
• “…a substance, a) intended for use in the diagnosis, cure, mitigation, treatment or prevention of a disease in man or other animals or b) a substance other than food intended to affect the structure or any function of the body of man or other animals”
• FDA regulates additives classified as drugs
• FDA approval
• Establish drug is safe and effective for specific species
• Establish safe for humans and environment
• Establish chemical and manufacturing specifications
• Requires extensive research
• Subsequent to approval
• Monitors labeling and feeding
• Monitors safety of animal products
• Marketing permitted after approval of new animal drug application
• Information regarding drug products in animal production: http://www.fda.gov/cvm/default.html
• Classifications
• Drugs in medicated feeds
• Category I
• Safest
• Require no withdrawal period
• Category II
• Require withdrawal period for at least one species or regulated on no-residue basis regardless of requirement of withdrawal period
• Table 9-1 on page 181 of text – Lists Category I and II drugs
• Medicated products
• Type A
• Concentrated premixes of product
• Added to additional feedstuff(s) prior to feeding
• Type B
• Added to additional feedstuff(s) prior to feeding
• Lower drug concentration compared to Type A
• Type C
• Products prepared for feeding
• Fed as complete feed, top-dressed, or offered ad-lib
• Consistent with specifications approved by FDA
• Registration with the FDA
• Required
• Commercial mixers mixing Category II, Type A
• Not required
• Commercial mixers mixing Category I or Category II, Type B
• Individuals subject to same registration requirements
• In addition to compounds classified as drugs, numerous additional additives
• Table 9-5 on page 191-192 of text – Information regarding additional special-purpose additives
