A pressed 18kg lick block supplying selenium, cobalt and copper — the three trace elements most often short in Australian grazing country, and the ones whose deficiency shows up as ill-thrift long before anything more obvious.
Target it rather than feed it by default. Selenium and copper both have a narrow margin between deficient and toxic, and copper in particular is dangerous to sheep at rates cattle handle comfortably. If you do not already know your country is short on these elements, a soil or blood test is worth more than a block. Where a deficiency is established, a lick block lets stock self-medicate at a steady low rate without a yarding.
Supplied as a single 18kg block. Freight on that weight is unavoidable, so pickup or combining it with the rest of a paddock order is the sensible way to buy it.
