Follicular Dynamics

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.

Ovarian Cycles

Following parturition in the cow, there is a significant period of sexual quiescence of variable length. This period of reproductive quiescence was found to be longer in suckling or intensively milked animals.This acyclic period is generally considered as the postpartum anoestrous period. The postpartum period constitutes an important period in the reproductive life of dairy cows because of its enormous influence upon subsequent fertility. The entire postpartum period, puerperium, is defined as the period from parturition until the genital organs return to its normal physiological and histological condition, as in normal non-gravid state. They added that any extension of the puerperium in cows might have a detrimental effect on the reproductive performance of the individual animal. Thus, the main determinant of this period is essentially dependent on the resumption of normal ovarian cycles, the manifestation of estrus behaviour and conception following insemination.

Holstein Dairy Cows

The aim of this study was to investigate the effects of metabolic diseases on uterine involution and reproductive performance during the postpartum period. Multiparous Holstein dairy cows (n = 50) were divided into four groups based on whether they were healthy (n = 14), or had lipomobilization (n = 14), hypocalcemia (n = 11), and hyperketonemia (n = 11). Transrectal palpation and transrectal B-Mode sonography were carried out on days 7, 14, 21, 30, 45 and 60 after parturition. Cows with metabolic disease had a greater (p < 0.05) uterine size as assessed transrectally compared with cows without metabolic disease. Sonographic measurements revealed a greater (p < 0.05) horn diameter and endometrial thickness in cows of the metabolic disease groups than in the healthy cows. Metabolic disease affected (p < 0.05) the milk yield, percentage of service per pregnancy, days to first ovulation and days open. In conclusion, metabolic disease affected the uterine involution and fertility during the postpartum period.

After delivery, the process of uterine involution begins, in which a series of changes in the anatomy and histology of the uterus take place and there is a return to cyclical activity of the ovary. The objective was to evaluate the effect of the application of estradiol benzoate and prostaglandin F2α (PGF2α) in the postpartum period on reproductive performance in dairy cows. Six experimental groups were formed in a 2 x 3 factorial arrangement, where a factor determined the administration of estradiol (E2): a) without E2 or b) with E2 (10 mg of estradiol benzoate was applied at 14 days postpartum) ; and another factor determined the administration of PGF2α: a) without PGF2α, b) administration of PGF2α in early postpartum (application of 25 mg of dinoprost at 28 days repeated 14 days later) or c) administration of PGF2α in late postpartum (application of 25 mg dinoprost at 42 days repeated 14 days later). 96 intensively reared Holstein cows were used for the experiment. The variables of interest evaluated were the cumulative pregnancy percentage (PA), the pregnancy rate (TP), the conception rate (TC), the service rate (TS), the first service delivery interval (IP1S) and the interval conception delivery (CPI). For the statistical analysis, the generalized linear model was used. As independent variables in the model, the administration of estradiol, the administration of prostaglandin and the interaction of both factors were analyzed. No significant effect (p> 0.05) of the application of E2 and PGF2α was found on TS, TC, TP and BP. However, a significant effect (p <0.05) of the application of prostaglandin on IP1S and IPC was observed, finding that the administration of PGF2α in the early or late postpartum significantly decreased IP1S. While the CPI was significantly better with the application of PGF2α in the late postpartum period. In conclusion, the application of prostaglandins from day 42 post parturition repeated 14 days later significantly improves the IP1S and IPC in dairy cows.
