Abstract
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.
Highlights
Animal efficiency is considered one of the most important aspects related to profitability in the livestock industry, as it directly affects herd productivity, and depends primarily on nutrition, health, genetics, and management factors
According to Opsomer at al. (2000), a normal ovarian cycle in the puerperium is one of the most important reproductive events related to high production in modern dairy cattle herds, which is aimed at achieving maximum potential after parturition
The aim of this review was to present viewpoints related to follicular dynamic in dairy cows, and to highlight the influence of follicular dynamics on the reproductive performance of dairy cattle during the puerperium period
Summary
Animal efficiency is considered one of the most important aspects related to profitability in the livestock industry, as it directly affects herd productivity, and depends primarily on nutrition, health, genetics, and management factors. The bovine female may be affected by metabolic or physiological disorders that cause infertility. Six weeks after parturition, the bovine reproductive tract achieves the volume, size, position, and reproductive capacity required for the pregnancy (Grunert and Birgel, 1998). (2000), a normal ovarian cycle in the puerperium is one of the most important reproductive events related to high production in modern dairy cattle herds, which is aimed at achieving maximum potential after parturition. The aim of this review was to present viewpoints related to follicular dynamic in dairy cows, and to highlight the influence of follicular dynamics on the reproductive performance of dairy cattle during the puerperium period
