Mineral elements in the nutrition of larger mammals

Abstract

The larger mammals, in spite of a wide diversity in diet, differ comparatively little in total mineral or ash content of the whole body. Because of the quantity required, calcium and phosphorus are the most commonly deficient elements. Tetany caused by a deficiency of magnesium is a problem in many areas. Deficiencies in trace elements are frequently the most dramatic in terms of the problems presented and the rapid response to minute increases in intake. The interrelationships, both direct and indirect, have caused nutritionists to realize that, in spite of many advances, there are many unanswered questions about the requirements and functions of the mineral elements in the larger mammals. The bulk of research has been with domestic species, but there is every reason to believe that wild herbivores are equally susceptible to deficiencies in these important nutrients. © 1968 by the American Society of Zoologists.
