A cow magnet is a large magnetic pill (2 1/2" long x 1" thick) that is put into a cow's stomach (specifically the reticulum). It collects any screws, bolts, nails or wire or anything else the cow may pick up along with the feed she eats. Magnets prevent what is called "hardwire disease," which is a malady that occurs when a foreign object punctures the stomach wall (primarily the reticulum), and bacteria enter from either outside or inside the cow's stomach causing infection, weight loss, and loss of appetite. The magnet keeps all of the hardware together in one spot when the reticulum contracts as the animal eats.
They don't. The magnet stays in the cow for the rest of her life.
Some cows have magnets inside their stomachs! The magnets attract any metal that the cow might accidently eat, which would harm or kill the cow if it passed through the digestive system. A cow can keep a magnet inside the stomach for it's entire life without harm.
A "cow" is a cow when that "cow" is a she and she has given birth to at least one calf.
Cow dung, cow patty, cow pie, cow feces, etc.
Elsie the cow was/is a Jersey cow.
They don't. The magnet stays in the cow for the rest of her life.
It doesn't. The magnet stays in the reticulum for the whole entire life of the animal.
Yes
The exact same way that a normal magnet attracts metal.
Cows don't have "built in magnets." Magnets are inserted down the throat of a cow as a way to prevent her from getting hardware disease from eating too much scrap metal like nails and wire. The magnet in a cow works exactly the same as any "normal" magnet does.
You can't. It doesn't matter which end of a cow magnet is North or South. As long as it can pick up metal and the metal sticks to it, then it works just fine.
Get a veterinarian out as soon as possible. No cow magnet is going to prevent glass from puncturing the animal's insides.
Yes. Most cow magnets can weigh around a pound or two each, but often never exceed three.
Just get a fairly strong magnet, I used a cow magnet. Wrap the magnet in a cloth so as not to scratch the face of the panel. Place the magnet over the needle and rotate it counter clockwise. If the magnet is strong enough the needle will return to its proper position.
You could, but it really doesn't hurt her if you give her one extra by accident.
Go to your vet, buy a bolus-pill plunger and a pack of bolus magnets (some call them cow magnets). Restrain the cow, put the magnet pill in the plunger, open the cows' mouth, put the plunger at the back of the cows' throat, and pop the pill in. The magnet will stay in the cow's reticulum (the "hardware" stomach where bits of metal and string accumulate), picking up the nail she just ate as well as other things she ate by accident. The magnet will help keep the hardware from puncturing her stomach, causing infection and a malady known as "Hardware Disease."
