If you are a young calf ready for your vaccinations and live outside the barn, you not only get your vaccinations, a dose of vitamins and a thorough examination, but you get also a stainless steel rod that holds together a series of very strong magnets the size of a small human finger. The magnet will stay with you for the rest of your life.
Why does a cow feed a magnet? During grazing and life on the farm, cows unintentionally take in all kinds of metal objects, including pieces of wire, staples and other metal waste. This is largely due to the fact that cows do not really distinguish between what they eat and they do not chew on their food completely before swallowing ̵
These strange objects travel through the cows with multiple rooms and often end up in their intestinal tract where they can catch on and stay there for the cow's life. This accumulation of metal objects in the intestinal tract can be a so-called & # 39; hardware disease & # 39; and has symptoms ranging from localized inflammation to reduced milk production and even death.
The purpose of the large pill-shaped magnets that are administered to the young calves serves as a capture device for future captured metal objects. The metal objects stick to the magnet and remain in the first primary chamber of the cow's stomach, where they can do considerably less damage than if they had traveled freely through the cow's digestive tract.
