Cows are one of the most common sources of milk, beef and leather. Dairy cows produce large quantities of milk, which is often pasteurized and generated into other dairy products, such as butter, yogurt and cheese. Beef cattle are raised for their meat and produce other byproducts.
When a dairy cow is no longer able to produce milk, she is then used for meat. The fat from cattle or beef tallow is used in making margarine, shortening, soap, crayons, lubricants, wax paper, shaving cream, lipstick and other cosmetic products. Cowhide, or the skin and hair of cattle, can be treated and processed into leather that is suitable for manufacturing wallets, shoes, furniture upholstery, leather jackets and belts.
