Care should be exercised with livestock fed a ration supplemented with copper or if copper bullets have been administered. For troughs of less than 7000-litre capacity, each 200g block should be divided into the proportion appropriate to the volume of the trough. If stock is suspected of having Lupinosis, remove blocks from the trough immediately. This product should not be used or should be used with care when the animals are already copper sufficient or have been grazing in a pasture containing plants that cause liver damage.
