Periparturient Events and Subsequent Fertility in Dairy Cows

Abstract

Nutrition in the dry and immediate postpartum period directly affect reproductive performance. Nutritional effects on fertility are mediated through a complex of complications at calving and metritis. Cows in negative energy balance during this period have
increased incidence of metritis, altered hormonal profiles and delayed conception. Successful reproductive programs
must recognize these early indicators of impaired fertility and, when indicated, implement control and treatment programs.
