Abstract
Although references to the feeding of "salts" to domesticated animals can be traced back to the time of Plutarch and although both Pliny and Virgil extolled the value of salt for milk production, detailed studies of the need for minerals by farm animals did not commence until this century. In fact, 50 years ago rations were judged by their ability to provide protein and energy and it was not until the importance of the "accessory food factors" or vitamins had been realized, and evidence obtained of the spectacular recoveries which could be produced by feeding vitamins to deficient animals, that biochemists received the necessary stimulus to search for other "deficiency diseases". This work quickly demonstrated that mineral deficiencies imposed a heavy annual drain on the economics of livestock production in general and that certain specific mineral supplements could cure serious pathological conditions.
