The puerperium in dairy cows: ovarian activity, uterine involution and follicular dynamics

Resumo

The study of ovarian follicular dynamics (OFD) and other changes in the bovine reproductive tract has developedsignificantly over the past two decades, primarily due to the use of non-invasive investigative approaches suchas ultrasound. Advances in ultrasound examinations have provided a better understanding of ovarian activity,uterine involution, oviducts status, and other segments of the reproductive tract in the bovine postpartumperiod. Procedures including tracking of the reproductive tract have likewise aided in the development of newmethodologies and techniques to improve reproductive performance in cattle. The aim of this review was tosummarize knowledge regarding the reproductive tract in dairy cows during the postpartum period.
