What is the scientific name for hardware disease?

Answer 1

bovine traumatic reticuloperitonitis

It occurs when a ruminent animal (cows, sheep, deer, etc.) digest a piece of metal, mostly likely wire or a nail. However it ends up puncturing the wall of the reticulum and eventually puncture the heart, effectively killing the animal. Can be prevented with a cow magnet, which looks like a metal pill.

It's most common in dairy and beef cattle, but is rarely seen in other ruminents, Since they are more selective in their diets, and are not in the feedlot situation as often.
