Which trace mineral is highly toxic to sheep?

Explanation:
Copper is highly toxic to sheep because they accumulate it in the liver and have a low hepatic tolerance. When copper builds up and a stressful event occurs, copper is released into the bloodstream, causing oxidative damage to red blood cells and acute hemolysis, which can lead to rapid death. This species-specific sensitivity makes copper toxicity the most notable trace-mineral danger in sheep nutrition. Selenium, iodine, and zinc can be toxic too, but copper toxicity in sheep is the classic, most pronounced risk due to their unique copper metabolism.
