Abstract

Nearly half of dairy cows develop at least one health problem in the early postpartum period, which is associated with impaired reproductive performance. The mechanisms by which health status impairs fertility are not fully understood, particularly regarding expression of estrus, which is relevant for herds that use estrus detection in reproductive management. Our objective was to identify postpartum health variables associated with reduced detection of spontaneous estrus using activity monitors in dairy cows.
