A cow initially chews just enough to swallow. Later, the cow burps up small amounts of food and chews it again. Food provides cows with protein, energy, vitamins, minerals, and bulk. It is also the raw material that makes milk. However, to begin producing milk, a cow must first give birth.
Cows produce the greatest amount of milk right after they give birth.
If a cow is not milked, she will stop producing milk. Milk is made and stored in the cow's udder, which is divided into four separate quarters, each having its own milk supply. When laden with milk, each section can be drained through one teat . First the farmer spray-washes the cow's udder with a warm iodine solution to control diseases. The milking machine cups are then attached and draw the milk from the udder into a system of pipes that transports the warm milk to a large storage tank for cooling.
