Abstract
A method of administering micronutrients to animals over extended periods by subcutaneous implant. Important micronutrients, including iron, copper, selenium, zinc, manganese, cobalt, molybdenum, chromium, silicon, iodine, biotin, vitamins E and B.sub.12 are supplied conveniently, and in positive, predetermined amounts by means of subcutaneously implanted pellets containing the micronutrient and a suitable excipient to provide controlled release of the micronutrient over an extended period of time. One example comprises iron dextran in combination with a lactose, fibrin, or other suitable excipient, in the form of a pellet which is subcutaneously implanted behind the ear of piglets to supply sufficient iron for optimum growth and to avoid iron-deficiency anemia. Important trace elements which may also be administered in carefully controlled amounts in suitable salt forms by the method of this invention include nickel, tin, vanadium, fluorine and arsenic.
