History

 After industrialization and urbanization, milking became commercialized. At that time, many dairy breeds were created through artificial selection for the dairy industry. These differ from the behavior of draft animals. Many people got jobs in various departments. However, milking soon became mechanized. Milking machines were designed. Farmer hand milking Historically, milking and spaying were closely spaced on the dairy farm. People milked milk by hand when dairy farms were short of milk. The milk teeth are squeezed by holding the milk stalks between the fingers from the base to the stalk. The nipple is located between the thumb and forefinger. Then by pressing those fingers from the nipple to the nipple, they milk the moving color. As the hand and finger squeeze the teat under the udder, the downward movement of the lid advances through the teat and reaches the teat to express the milk into a bucket or cup placed below. The teat in each half of the udder is alternately milked to its full extent.
