The elite milk producing phenotype of the modern dairy cow has adversely affected its health. Diminished udder health has serious implications for milk production, leading to decreases in milk yield, milk quality and increases in somatic cell count. This new book presents current research in the nutrition, fertility and milk production of dairy cows. Topics discussed include mastitis in bovine milk production; oxidative stress and reproductive disorders in dairy cows; the incidence of hypocalcemia and its Ca homeostasis mechanism in periparturient cows and the haemodynamic changes of the superovulated corpus luteum in cattle.
