Description
Product Overview
The Master Magnetics Ferrite Cow Magnet is engineered for robust magnetic performance in a compact, livestock‑friendly form factor. Measuring 3 inches in length, 0.67 inches wide and 0.65 inches high, each magnet is crafted from high‑grade ferrite (ceramic) material that delivers consistent pull strength while remaining safe for animal consumption. A black powder‑coat finish protects the magnet from corrosion, ensuring longevity even in the harsh, acidic environment of a ruminant’s rumen. The product ships as a pack of four, providing enough units for multiple animals or for keeping spares on hand for preventative health programs.

Usage
These magnets are designed specifically for use in cattle, goats, sheep, and other ruminants that are prone to ingesting stray metal objects such as nails, wire, or farm equipment fragments. By placing a magnet in the animal’s stomach, the magnetic field captures and holds metallic debris, preventing it from causing internal injuries or reducing feed efficiency. The magnets are typically administered orally using a drenching gun or a specialized applicator, allowing the device to settle safely in the rumen where it remains effective for several months. Because the magnets are low‑cost and reusable, they are a practical choice for large‑scale livestock operations, feedlots, and small farms alike.

FAQ
How long does a cow magnet remain effective?
Under normal feeding conditions, a ferrite cow magnet typically retains its magnetic pull for 3 to 6 months before a replacement is recommended.
Can the magnet be used for animals other than cattle?
Yes, the same magnet size works well for goats, sheep, and other ruminants that may ingest metal debris.
Is the black powder coating safe for the animal?
The coating is food‑grade and designed to withstand the acidic environment of the rumen without leaching harmful substances.
What is the recommended method of administration?
Use a calibrated drenching gun or a specialized magnet applicator to place the magnet directly into the animal’s mouth, allowing it to travel to the rumen.
Do I need to remove the magnet after its service life?
When the magnet loses its pull strength, it can be safely removed during routine veterinary checks or replaced with a new unit.
