Cage Magnets: Reliable Protection Against Swallowed Metal
Nails and pieces of wire in the feed can never be ruled out completely. Cage magnets hold swallowed metal safely in the reticulum.
Cage Magnets: Prevention Against Foreign Bodies
Cattle eat quickly and barely chew their feed before swallowing. Small pieces of metal from bale netting, fence remnants or harvesting machinery end up in the rumen before you know it. A cage magnet is given to the animal and stays in the reticulum. There it holds nails and pieces of wire and helps prevent traumatic reticuloperitonitis, which many farmers know as hardware disease.
How the foreign body magnet works
Sharp pieces of metal can pierce the wall of the reticulum and travel as far as the pericardium. A rumen magnet collects the metal in one place and keeps it away from the stomach wall. The cage shape means attracted pieces sit protected and do not rub against tissue. The magnet stays in the animal permanently and does not need replacing. Many farms give it when heifers come in or before the first calving, so protection is in place from the start. Make sure each animal receives only one magnet.
Administration and handling
For administration you use a suitable balling gun and restrain the animal calmly and safely. Work without hurry and the whole procedure goes quickly and with little stress. If you are unsure, ask your vet to show you the routine the first time. More important than any aftercare is prevention in the feed: check bale netting and twine, collect fence remnants and keep the silage clamp and feed table free of metal. If an animal goes off feed, arches its back or shows signs of pain, call your vet straight away.
Frequently asked questions
When do I give the magnet?
Many farms do it when young cattle come in or before the first calving. That way the protection works across the whole productive life.
Does the magnet stay in the animal?
Yes, it remains in the reticulum and collects metal there. There is no need to replace it, and a second magnet per animal makes no sense.
Does it replace checking the feed?
No, it is a safeguard. Clean work at harvest, at fencing and at feeding remains the most important measure against metal in the ration.
Cage Magnets for Cattle
Even with careful work, metal in the feed can never be ruled out entirely. A cage magnet is given to the animal, stays in the reticulum and holds nails, pieces of wire and other sharp items there. That clearly lowers the risk of traumatic reticuloperitonitis. The cage shape keeps the attracted metal together and protected, so it does not rub against the stomach wall. The magnet remains in the animal permanently, there is no need to replace it and one magnet per animal is enough. Many farms give it when heifers come in or before the first calving. Together with clean forage harvesting, checked bale netting and tidied fence remnants, you get simple and effective prevention for the whole herd. Because cattle eat quickly and barely chew their feed, this safeguard pays off.
