“…Different hormone treatments have been applied to induce oestrus after foal heat. Mares can either be short-cycled with prostaglandins after the foal heat ovulation (TOLKSDORFF et al, 1976; BURNS et al, 1979), or progesterone therapy (LOY et al, 1975;POPE et al, 1979) or a combination of progesterone and oestradiol (LOY et al, 1982) can be used to postpone the first p.p. oestrus.…”

Summary Fifty‐six post partum (p.p.) periods were studied in 41 mares. The mares were examined clinically (rectal palpation, ultrasound scanning, vaginoscopy) on the 2nd and 5th day p. p. and thereafter every other day until ovulation. Thirty‐five mares were inseminated in the first p. p. oestrus. The conception rate in the first oestrus was 45.7% and the final conception rate was 94.3 %. The mares were examined rectally, with an ultrasound scanner and vaginal speculum. None of the parameters examined (uterine size, tone and contents; endometrial folds; amount and character of vaginal contents; oedema and colour of portio vaginalis; age) was correlated with the fertility of foal heat insemination. Zusammenfassung Untersuchungen an der Stute post partum bezüglich der Fruchtbarkeit im Anschluß an die Fohlenrosse I. Rektale Palpation, Vaginoskopie und Ultraschalluntersuchung Sechsundsiebzig post‐partum (p.p.)‐Perioden wurden bei 41 Stuten untersucht. Die Stuten wurden am 2. und 5. Tag p.p. sowie anschließend bis zur Ovulation jeden 2. Tag klinisch untersucht (rektale Palpation, Ultraschall‐Untersuchung, Vaginoskopie). Fünfunddreißig Stuten wurden während des ersten p.p.‐Östrus inseminiert. Die Konzeptionsrate beim ersten Östrus betrug 45,7%, die endgültige Konzeptionsrate dagegen 94,3%. Die Stuten wurden dabei rektal, mit dem Ultraschall‐Scanner und dem Scheiden‐Speculum untersucht. Keiner der untersuchten Parameter (Uterusgröße, Tonus und Inhalt des Uterus, Endometriumfalten, Menge und Art des Scheideninhalts, Ödematisierung und Farbe der portio vaginalis, Alter) war mit der Fruchtbarkeit im Anschluß an die Besamung während der Fohlenrosse korreliert.

“…Pregnancy rates in this heat are lower than in subsequent heats [Caslick, 1937;Jennings, 1941;Tram, 1950;Ginther, 1979;Merkt & Gunzel, 1979;Lieux, 1980]. This probably happens because uterine involution and endometrial regeneration are not complete when foal heat occurs [Tolksdorff, 1976].…”

The use of methylergonovine maleate and cloprostenol was tested during uterine involution in mares of different ages to determine whether these treatments could increase pregnancy rates. A total of 311 Thoroughbred mares from Southern Brazil that had experienced normal parturition and given birth to live foals was studied. After parturition, mares were submitted to clinical examination and, if necessary, to vulvoplasty. At that time, mares were randomly assigned to one of the following groups: GI-methylergonovine maleate (n = 77); Gil-cloprostenol (n = 82); GUI-control group (n = 152). Mares were mated every other day after a preovulatory follicle (> 40 mm) was detected. Pregnancy diagnosis was made on Days 18 and 42 postovulation. There were no significant differences in pregnancy rates among groups. Average number of days between parturition and ovulation was 11.8 ± 3.4 (GI), 13.2 ± 4.5 (Gil) and 13.2 ± 4.0 (GUI). There was no relationship between ovulation day and pregnancy rate, but a significant shortening of the parturition-ovulation interval was detected in GI (p < 0.05). Pregnancy rate of mares in GUI with ages less than 10 yr was significantly greater than that of older mares (p < 0.05). This difference was not detected in GI and Gil.

“…Breeding of mares at the foal heat is preferable management while anestrus and low pregnancy rate commonly noticed when mares not bred at first foaling heat (Tolksdorff et al, 1976). Furthermore, predicting the day of ovulation should be considered in order to have a higher conception rate after mating and/or insemination of mares at first postpartum heat (Ginther, 2000).…”

Key words:Arabian horse, dominant follicle, nitric oxide, alkaline phosphatase Postpartum heat is very important for ability of mare's to conceive. The present study aimed to evaluate ovarian changes and its relation to oxidative stress during early postpartum period in Arabian horses. Further, the predication of conception according to the relationship between sonographic and biochemical changes analyses. Ultrasound imaging of follicular changes and oxidative analyses changes were investigated at day 7-9 postpartum whereas Receiver Operating Characteristic (ROC) curves were used to determine the ability of oxidative stress and ultrasound imaging to predict the conception rate. ROC analyses indicated that nitric oxide predicate the conception rate with sensitivity (79% P<0.003) and dominant follicle size (80-100% P<0.0001). Alkaline phosphatase, catalase, glutathione, glutathione S transferase and total antioxidant capacity (P>0.05) between pregnant and nonpregnant mares. In conclusion, nitric oxide and dominant follicle diameter plays a crucial role in enhancement the conception rate during foaling heat.
