Know about the milk

Tweet

Milk is the nutrient fluid produced by the mammary glands of female mammals (including monotremes). The female ability to produce milk is one of the defining characteristics of mammals. It provides the primary source of nutrition for newborns before they are able to digest more diverse foods. The early lactation milk is known as colostrum, and carries the mother's antibodies to the baby. It can reduce the risk of many diseases in both the mother and baby. The exact components of milk vary by species, but it contains significant amounts of saturated fat, protein and calcium. These amounts are not large in comparison to other foods rich in them, including coconuts, fish, and kale respectively, because milk is predominantly composed of water. Aquatic mammals, such as seals and whales, produce milk that is very rich in fats and other solid nutrients when compared with land mammals' milk.
