Cow Magnets | Magnetic Product Export from China

What are cow magnets?

Cow magnets are also known as rumen magnets. They are used in the rumen of a cow. Farmers use it to prevent hardware disease of their cows. Cows “eat” the magnets to keep themselves healthy so that they can be more productive at generating milk. The practice of farmers feeding magnets to their cows has been around for decades. The demand for this type of magnets are huge in agriculturally developed countries.

different cow magnets

A  dairy farmer or rancher feeds a magnet using a tube; the magnet stays in the rumen or reticulum and remains inside for the lifetime of the animal. The magnet is administered after fasting the cow for around 20 hours. Generally, this is done to the entire herd before the age of one because this will be the most effective.

Three types of cow magnets

Three types of magnets made of different permanent magnet materials are available in the market. 1) Ferrite cow magnets 2) Neodymium cow magnets 2) AlNiCo cow magnets. Cow magnets with different permanent magnet materials have their own versions. At Tengye, we supply all three types of magnets. We supply over 50% of the magnets to the USA, 30% to Europe and the rest to to Japan and New Zealand.

Ferrite magnet (also known as ceramic magnet) is made of strontium iron oxide (SrFe12O19), which is the cheapest version of rumen magnets. AlNiCo magnet is made of aluminum, nickel and cobalt, while neodymium magnet made of neodymium iron boron. It is also the most powerful but much more expensive magnet. Recently the price surge of neodymium raw material has caused many buyer to switch to Ferrite or AlNiCo types.
