Sharpie Ear Tag Marker

A rumen magnet captures metallic objects ingested by a cow before they can cause any harm

If let free, the metallic objects move from the rumen and get lodged in vital organs and most of the time cause traumatic reticuloperitonitis, which is also called hardware disease.

The cow magnets are made of non-toxic material which can stay in the cow’s stomach for life without causing any harm.
