Selenium has a range of functions in the body. In cases of deficiency, however, it is the antioxidant effects of selenium that are most missed.

White muscle disease in young lambs, and ill thrift in cattle are the most common clinical signs we see.

Selenium can be supplemented in the fertiliser, in the feed or water, and with short acting and long acting injection. The success (or otherwise) of the supplementation options varies considerably, and often some trial and error is required before a suitable solution can be found.
