The periparturient period is a period in which important hormonal, metabolic and physiological changes occur during late pregnancy and early lactation. During this period, energy balance, uterus involution, and timing of onset of ovarian activity may be negatively affected. In addition, high yield losses are also among the problems that may occur during this period.
