Recent Developments in Trace Elements in Animal Production

There is a continual need for further research to understand in greater detail the metabolism and function of trace elements, From recent studies it has been noted that: (a) The Se requirements of dairy cows have become more accurately defined and cattle, when compared with sheep,are less sensitive to Se deficiency. (b) High MO intakes and not the associated decrease in the Cu status of cattle ...
