How the Advance of the Period of Lactation Affects the Milk Flow

Abstract

Upon calving, the rate of milk secretion of the dairy cow gradually increases for a time and then gradually decreases until the animals become dry. The cause of the gradual increase in the flow of the milk after calving is undoubtedly due to the improving condition of the animal following parturition, increasing consumption of food, and to the gradual perfection of the mammary gland.
