Master Magnetics Ru-Master 5 Cow Magnet – Strong Heavy-Duty Magnets for Cows – Collects Nails and Other Tramp Iron

For over 50 years, dairy farmers and veterinarians have trusted the Master Magnetics Ru-Master 5 Cow Magnets to protect livestock. Cow magnets help prevent the harmful effects of cattle ingesting metal objects. While grazing, cows eat everything from grass and dirt to nails, staples, and bits of 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. The cow loses its appetite and decreases milk output (dairy cows) or its ability to gain weight (feeder stock). Cow magnets help prevent this by attracting and holding stray metal from the folds and crevices of the rumen and reticulum.
PROTECT YOUR HERD: For over 50 years, this heavy-duty magnet has been the favorite of dairy farmers and vets. It captures nails and other tramp iron cows may swallow while grazing, helping support their appetite, well-being, and milk production.
LONG-LASTING: Built to last the life of your cow, this 3.375″ long magnet features a stainless steel core and rounded steel end caps. It’s easy to administer with a balling gun and retains its strength without losing power.
POWERFUL MAGNET: The ceramic magnets and segmented steel rings deliver a strong, consistent pull to trap tramp iron. Slightly heavier than other cow magnets on the market, it travels more easily to the stomach.
EDUCATIONAL TOOL: This powerful magnet doubles as a hands-on teaching aid. Use it in classrooms to demonstrate magnetic fields and basic physics concepts in a clear, engaging way.
