Selenium is an essential element in the diet of animals and has a variety of roles:
A deficiency can cause white muscle disease (WMD) in lambs and weaners, scouring, ill thrift and lowered wool production in weaners and hoggets and in some cases infertility in ewes.
There are other diseases that cause similar clinical signs, and there are also other diseases which may be caused by a combination of low levels of both selenium and vitamin E.
Selenium deficiency must be confirmed as the cause of disease before treatment because selenium can be toxic if given in excess amounts.
