Additionally, follow the recommended dosage and frequency for feeding supplements. (Previously published online: Agriculture and Food, Department of Primary Industries and Regional Development). In general, cattle and goats are more resistant to copper poisoning than sheep. The sudden onset of clinical signs in chronic copper poisoning is associated with a hemolytic crisis. If the haemolysis is massive, sheep can die without showing any sign of jaundice. Then there are the less obvious sources. Occasionally, a sheep producer may purchase a feed supplement labelled for cattle not understanding that this feed contains toxic levels of copper. Avoid the use of mutilations as standard production practices. Death is rapid. Providing proper handling and storage of copper supplements: If adding copper supplements to their diet, make sure to follow proper handling and storage guidelines to avoid any unwanted exposure to sheep.
