A cow typically has four teats. Teats are the small projections on the udder of female mammals, such as cows, that secrete milk for their young.
Cows are known for their large udders, which can contain up to four mammary glands, one for each quarter of the udder. Each mammary gland has its own teat, which is used to extract milk during milking.
Having four teats is the most common arrangement in cows, although some may have extra teats, known as supernumerary teats. These extra teats do not produce as much milk as the regular teats and are often removed to prevent infection or injury to the cow.
In summary, a cow typically has four teats, one for each quarter of the udder, which are used to extract milk during milking. While some cows may have extra teats, having four is the most common arrangement.
