About the Cow Magnets:

While grazing, cows eat everything including any stray pieces of metal or nails
that may be lying in a pasture. When ingested, these bits of metal do not pass
through, but can instead puncture the lining of the cow's stomach and cause what
is known as hardware disease. Before this happens, a cow magnet is injected into
the cow's stomach with a pill gun, and catches all the stray metal the cow eats. 
cow stomach magnet will stay in the stomach for the life of the cow.  cow stomach magnet also
have many practical uses such as holding nails or other iron objects in place,
or cleaning up nails or staples that have been scattered. This cow magnet consists of five ceramic ring
magnets with two washers in between each magnet and solid steel end caps.
