Sodium and research in farm animals: problems of requirement,deficit,and excess

Abstract

There is no doubt of the biological importance of salt in the physiological processes of all animals. Nevertheless, there is great uncertainty about the level of salt intake necessary to maintain the health of farm animals in varying circumstances such as pregnancy and lactation. It appears that published recommendations are far too high, which is not only misleading from the veterinary point of view but is reflected in exaggerated estimates of human requirements.
