Cow magnets are originally intended & widely used to help prevent "Hardware Disease" in livestock. "Hardware Disease" is caused when cows swallow nails, staples, & bailing wire while grazing. This can be fatal to the cow because the metals threaten the reticulum & surrounding vital organs of the cow. When properly administered, a cow magnet will collect the metals & bailing wire for the lifetime of the cow. Consult a veterinarian on how to administer the magnet.
