Controlled release of mineral nutrients and other pharmaceuticals for sheep and cattle



Controlled release of mineral nutrients and other pharmaceuticals for sheep and cattle



Proceedings of the 6th International Conference on Production Disease in Farm Animals, Belfast: 171-173



Controlled-release glass (soluble glass) containing copper was unsuitable for subcutaneous implantation into cattle, but it could be administered orally as a 75 g bolus, providing a continuous supply of Cu for up to a year. Cobalt could also be incorporated in soluble glass. Experiments were under way to incorporate organic drugs within soluble glass, and one possibility was the production of a sintered block of controlled-release glass, filled by immersion in a solution of the drug.
