Cow Magnet
Item #: WMCW-100
Sorry, this item is temporarily unavailable

These super strong cow magnets have earned that name by saving countless cows from developing the dreaded hardware disease. How? The solid Alnico magnet is placed in a cow's first stomach to collect all of the metal objects that poor Bessie might accidentally eat. Cows just can't tell the difference between grass and nails. Ouch! Recommended for children ages 8 and up.

How does it work?

Cow magnets are widely used by ranchers and dairy farmers to help prevent Hardware Disease in their cattle.

While grazing, cows eat everything from grass and dirt to nails, staples and bits of bailing wire (referred to as tramp iron).

Tramp iron tends to lodge in the honeycombed walls of the recticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as Hardware Disease.

The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and recticulum.

One magnet works for the life of the cow!
