Bovimax+ is a brand of cage magnet or ruminal magnet marketed by AIP Medical. The principle of the cage magnet is as follows. The anisotropic ferrite magnet is placed in the center of a plastic cage. The veterinarian administers it to the cows with the help of a bolus launcher in order to prevent rumen lesions in cattle. It attracts unwanted ferrous foreign bodies by its magnetic force and holds them in the cage. These ferrous metals can be fatal to cattle when ingested. To avoid this, there is nothing like the Bovimax+. It is one of the most powerful magnets on the market. Bovimax+ is delivered without a bolt thrower in a box of 12 magnets.
