When shopping for farm and ranch supplies online, make sure you don’t forget to pick up low-priced cow magnets from HardwareWorld.com. Cow magnets are def to calves at branding time, where they then settle into the rumen of the cow and remain there for life. Cow magnets prevent items such as barbed wire, staples, nails or other metallic objects from lodging into the tissue of the cow and causing inflammation. Internal tissue inflammation can result in low milk production and low weight gain in cows, otherwise known as "hardware disease". Our cow magnets are safe, non-toxic and non-corrosive and will attract any damaging metal objects that may be accidentally ingested. Make sure to shop HardwareWorld.com for all of your farm and ranch supplies and save time and money.
