Product Details
Alnico Cow Magnet Rumen Magnet Rod is manufactured in our factory from high-grade cast Alnico alloy specifically for veterinary and livestock applications. We produce these rods with a smooth surface and carefully rounded ends so they can be administered safely and settle properly in the reticulum.
The Alnico Cow Magnet Rumen Magnet Rod is typically made in Alnico 5 grade, which offers stable magnetic performance and good resistance to demagnetization under the conditions found inside the animal. Once administered, the magnet remains in place for the life of the cow and continuously attracts nails, wire, staples and other ferrous debris that cattle may swallow while grazing. This helps reduce the risk of hardware disease and supports better feed efficiency and milk production.
Our production process includes alloy casting, precision grinding, magnetization and final inspection to ensure consistent dimensions and magnetic strength. Standard size is 12.7 mm diameter by 76.2 mm length, but we can also supply other lengths and diameters according to customer requirements. Surface finish is polished for smoothness, and each batch is checked for appearance and magnetic properties before packing.
If you need to buy Alnico cow magnet rumen magnet rod or are looking for a reliable source of wholesale Alnico rumen magnets for cattle, our factory can provide samples for evaluation and support both small trial orders and ongoing bulk supply.

FAQ
Q1: Can the magnet be reused if recovered from the animal?
In normal practice the magnet stays inside the cow for life. If recovered, it can be cleaned and inspected, but most users treat it as a single-use lifetime device for each animal.
Q2: Do you supply different lengths or diameters for larger or smaller cattle?
Yes. While 12.7 × 76.2 mm is the most common size, we can produce other diameters and lengths according to your specification or drawing.
Q3: What packaging options are available for bulk orders?
We can pack the rods individually in protective sleeves or trays and then into cartons suitable for export. Custom labeling and bulk packaging are available on request.
