The milk is the most complex food and it is sufficient, during a time more or less considerable, and in some cases for a year or more, all feeding infants and small animals. You drink the milk of cows, sheep, goats and even camels and asses. The color is an opaque white, slightly sweet flavor, delicate, and yet perceptibly vary not only by species of animals, but also according to their diets. The flavor of certain herbs can be found regularly ingested in milk.
Of course, the more usual cow’s milk, but others also have similar composition and behavior. It is food with high caloric value, especially to sugar and oil, but its nutritional value is extraordinary for the constructive power of wear and repair of various cell substances contained therein.
