Cow Magnets

Cow magnets are popular with dairy farmers and veterinarians to help prevent Hardware Disease in 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 reticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as Hardware Disease. The cow loses her appetite and decreases 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 reticulum. One magnet works for the life of the cow!

Ru-Master 5 Cow Magnet

The Ultimate Heavy-Duty Cow Magnet!
Patent No. 5128644

The patented design of the Ru-Master 5 improves upon the quality and longevity of the original heavy-duty rumen magnet. In comparison, the Ru-Master 5 is:

Durable Its durable structure boasts plated, solid steel end caps for corrosion prevention and a solid steel connector rod through the core to reduce breakage in shipping and handling. No plastic parts involved.
Stronger Magnetizaton before assembly creates a consistent pulling force from each section along the length of the magnet and enhances its overall strength.
Superior Characteristically, the Ru-Master 5 has rounder ends and is slightly heavier than the original heavy-duty cow magnet. These qualities make it easier for the magnet to travel to the stomach and stay there.
