“…In the mare, the progress of uterine involution can be monitored by several clinical findings (Stanton, 2011). Gravid uterine horn diameter (GUHD) returns to its pre-gravid state around Day 23-24 post-partum (McKinnon et al, 1988;Lemes et al, 2017). Intrauterine fluid accumulation (IUFA) is considered as a clinical sign for mares susceptible of developing endometritis, as delayed uterine clearance or excessive fluid production are predisposing factors in the development of endometritis (Katila, 2016).…”

To test the hypothesis that delayed/impaired uterine involution could be associated with oxinflammation, we studied the progression of the uterine involution in association with some biomarkers of inflammation and oxidative stress in clinically healthy mares (N ¼ 26) during early postpartum. The examination of the reproductive tract was performed on Days 7 and 21 after foaling. Uterine involution was assessed considering: a) the increase of the gravid uterine horn diameter (GUHD) compared with diameter recorded before pregnancy during the previous breeding season; b) the level of endometrial edema (EE); c) the degree of accumulation of intrauterine fluid (IUFA); d) the status of the cervix (CS). Inflammation and oxidative stress were studied by measuring serum amyloid A (SAA), cortisol, DHEA, AOPP, protein carbonyl groups, malondialdheyde (MDA) and thiols in plasma on Days 7 and 21. By Day 21 after parturition, a significant improvement (P < 0.01) was observed for GUHD and EE; while IUFA increased in six animals. Plasma SAA and DHEA concentrations were higher when the clinical parameters indicated a lower degree of uterine involution. On Day 7, the cortisol/DHEA ratio was lower in animals with higher degree of EE. Plasma AOPP and MDA concentrations were significantly lower (P < 0.05) in animals with the lower GUHD. On Day 21, plasma MDA concentrations were significantly lower (P < 0.05) in animals with the lower IUFA. Our data suggest that a mild condition of inflammation and oxidative stress occur in mares with delayed/impaired uterine involution.

“…Relationship of uterine vascular perfusion associated with involution of the postpartum uterus was mentioned in the study by Lemes et al [56] using the UCF mode of uterine segments. The authors observed that vascular perfusion increased in endometrial and mesometrial tissues in the first 2 to 4 days after delivery, followed by a progressive decrease until the second week postpartum.…”

Doppler ultrasonographic (US) is a method that provides real-time information on vascular architecture and hemodynamic aspects of blood vessels. It can determine the presence, direction, and speed of blood flow, being subdivided into the categories of color Doppler (color flow and power flow) and pulsed Doppler. The objective of this chapter was to compile data from several studies addressing the use of US Doppler correlated with pathophysiological phenomena of equine reproduction. Initially we decided to describe the technique, advantages, and disadvantages of each Doppler mode. Then the applicability of US Doppler in mares related to equine reproduction. Thus, within this chapter, you will find the form of use and descriptions of studies carried out on vascular perfusion of the follicular dynamics, the corpus luteum, the uterine segments, which we have divided into post-insemination evaluation, endometritis diagnosis and pregnancy diagnosis. So, we hope that this chapter will expand the knowledge about US Doppler and increase the number of veterinarians who will introduce the technique into their practical routine.

“…Além disso, sendo a égua um animal que apresenta rápida involução uterina, tendo a primeira ovulação pós-parto em torno de 12 dias (LEMES et al, 2017), é muito comum que elas se tornem gestantes ainda durante a lactação. No entanto, no nosso conhecimento não existem trabalhos que avaliaram a influência da lactação nas características metabólicas durante toda a gestação, não havendo conhecimento sobre a influência dessa condição no metabolismo de lipídeos e carboidratos, produção e sensibilidade à insulina assim como na produção de adipocinas.…”
