“…However, the high value of this method in the diagnosis of pregnancy, the presence of a persistent CL in the absence of pregnancy may occur, resulting in an incorrect result (decrease the Sp). This method is not specific and reliable to determine non-pregnancy status in the early period post-mating due to failure of CL to lysis at the expected time especially if uterine pathology and embryonic death occurrence that prevent CL regression [44].…”

The primary objective of this study was to measure the expression profile of the signal transducer activator transcription 1 (STAT1) in the circulatory leukocytes of non-pregnant/pregnant ewes and test the possibility that it could be useful for detecting early pregnancy. Whole blood was collected from 20 ewes (control) and another 5 samples were taken on days (15, 25, 35, and 50). Also, blood was collected from 30 ewes on day 15 post insemination (PI) and another 10 samples were taken on days (25, 35, and 50) PI. Total RNA was isolated from peripheral blood leukocytes (PBLs), and STAT1 expression levels were determined by quantitative real-time PCR (qRT-PCR). Gene expression for STAT1 mRNA was 5.8-fold and 5.1 times higher in gravid as opposed to non-gravid ewes. The reliable cut-off point > 1.45 was established using the receiver operating characteristic (ROC) curve, and the accuracy (Acc) for detecting pregnancy was 82%, 93%, 70% and 60%, and the sensitivity (Se) was 83%, 80%, 60% and 33% and Specificity (Sp) 95% on days 15, 25, 35 and 50, respectively. The mRNA expression was lower in ewes that control non-pregnant than pregnant ewes on days 15 and 25. So The best period to detect pregnancy was 15-25 days PI.

Background The risk of developing tumorous diseases in the genital tract also increases with age in animals. One of the classified tumor types is genital leiomyoma. Presently, our understanding of the pathogenesis of this tumor in goats is, however, limited. This accounts also for the information regarding the presence of steroid hormone receptors and, thus, possible responsiveness to circulating steroids. Case presentation This study describes the case of a vaginal tumor in a seven-year-old Anglo-Nubian goat. The goat was presented due to blood mixed vaginal discharge. Per vaginal examination a singular pedunculated mass in the dorsum of the vagina measuring approximately 3 cm x 4 cm x 4 cm was revealed. After administering epidural anesthesia, the mass was removed electrothermally. There were no postoperative complications. The histopathological examination identified the mass as a leiomyoma. The immunohistochemical examination revealed the presence of the nuclear progesterone receptor (PGR) in the tumor tissue. One year after the surgery, during the follow-up examination, the goat was in good overall health, and the owners had not observed any recurrence of vaginal discharge. Conclusions When observing vaginal discharge in goats, it is important to consider the possibility of genital tract tumors. These tumors may express sex steroid receptors. In the future, it is worth considering the investigation of potential approaches for preventing tumorigenesis or treating the tumor, such as castration or the administration of antiprogestogens.

Anatomical and ultrasonographic diagnostic work-up of testicular abscesses (n = 2) and testicular microlithiasis (n = 3) in Kazakh rams is described. For testicular abscesses, the localized symptoms include enlargement of the testicle and decreased elasticity, accompanied by varying degrees of pain and fever, abnormal behavior, walking or urinating with legs spread apart and accompanied by painful moans. Ultrasound findings: several hypoechoic or fluid dark areas with irregular morphology appear within the testicular parenchyma, with unclear borders with the surrounding normal tissues and uneven internal echogenicity. An autopsy revealed unilateral caseous necrosis with degeneration of all testicular tissues. Testicular microlithiasis does not present clinically and normal semen quality is not affected. Ultrasound findings: sparse, scattered, or dense punctate, pinpoint-like echogenic dots, some with comet tail signs and no acoustic shadow, are seen in the testicular parenchyma. The routine treatment for testicular abscesses is surgical drainage, but when degeneration and necrosis of testicular tissue occur, leading to severe systemic symptoms, the animal must be put down. Testicular microlithiasis is relatively rare and there are no effective treatments or interventions available, but it remains a potential contributor to testicular dysfunction and other secondary conditions.
