Feed Manufacturers

Feed manufacturers are involved in the sale of non-prescription drugs and the preparation and sale of medicated feeds. They ensure that the correct concentrations of the proper ingredients are adequately mixed in feeds. They are responsible to ensure the feed tag label includes the directions for use and pertinent caution and warning statements to be observed by the livestock producers. The Compendium of Medicating Ingredient Brochures (CMIB) from Canadian Food Inspection Agency contains information on the use of drugs in feed, including permitted drug and drug combinations for use in animal feeds. When a medicating ingredient is at a level or for a purpose not listed in the CMIB, a written prescription by a licensed veterinarian is required. Manufacturers must ensure 1) the drug is prescribed for prophylactic or therapeutic purposes and not as a growth promotant; 2) the drug has an identification number (DIN) under the Food and Drugs Act; and 3) the animals are under the direct supervision of the veterinarian.

The manufacturer must have a copy of the prescription in his possession prior to delivering the feed. Labels for veterinary prescription feeds must contain the standard labelling requirements as prescribed in the feed regulations, as well as: (1) the name and address of the manufacturer; (2) the name of the person for whom the feed is manufactured; (3) the name of the veterinarian who issued the prescription; (4) the name of the feed, including the name and amount of medicating ingredients; (5) directions for use, including duration of feeding; (6) warning and caution statements; and (7) the weight of the feed.
