Biological Availability of Minor Mineral Ions: A Review^{1, 2,}

University of Florida,³ Gainesville, Florida 32601

Abstract

The mineral ions to be considered in this review are iodine, iron, copper, cobalt, zinc, manganese and selenium. Each of these elements has been shown to be required as a dietary supplement for grazing ruminants in certain areas of the world (Underwood, 1971). In general, the mixed grain diets fed to swine and poultry are less likely to be deficient in these elements. Other minor elements either suggested or considered to be essential for normal functioning of tissue include chromium, vanadium, tin, nickel, bromine, fluorine, and molybdenum (Mertz, 1970; Underwood, 1971). These elements, however, do not appear on the basis of present evidence to be required as dietary supplements for domestic animals.

The relative biological availability of the desired element in a compound or supplement is one of the major considerations in the selection of a suitable source of the element. Sources of many of the supplemental minerals are natural ores or by-products of industry which usually contain many mineral elements.
