Magnet Source 7239 Cow Magnet, Alnico/Metal, Silver, Aluminum

The standard alnico cow magnet is used to prevent hardware disease in cows and is ideal for 3D classroom experiments, including demonstration of magnetic fields. This heavy-duty magnet collects nails, staples and baling wire (also called tramp iron) that cows swallow while grazing. Tramp iron tends to lodge in the honeycombed walls of the reticulum, threatening the surrounding vital organs and causing irritation and inflammation. The cow loses her appetite and decreases milk output (dairy cows) or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and reticulum. When properly administered, one cow magnet will last the life of the cow. Consult veterinarian on how to administer the magnet.
