“…According to similar studies performed in ewes and goats, the FHR curve descends corresponding to the progression of pregnancy (8,11,12,16). We observed a similar decreasing trend and no difference in FHR between single and twin Karya foetuses.…”

“…It can also be seen that the FHR values were above 220 bpm during the first trimester and below 190 bpm in the third trimester of these healthy pregnancies. In the results of our previous study (16), no difference was recorded between single and multiple pregnancies of Saanen goats. Regarding cardiac effects related to diseases and some stress factors, the study subjects were selected from healthy animals and environmental stress factors that can increase FHR sensitivity were minimised.…”

“…Abnormal heart rate patterns are suggestive of foetal distress (13). Although it is well recognised that FHR decreases during the course of pregnancy in farm animals (3,11,(14)(15)(16) except in goats (16), there are no data available on the FHR curve through singleton and multiple pregnancies in domestic animals.…”

“…Thus, the possibility in differences in foetal Doppler data in multiple pregnancies should be considered. There are some data regarding singleton and multiple pregnancies from human medicine (21,23,24), but only one report in veterinary practice (16). In the current study, the authors sought to compare biometric parameters for single and twin foetuses, in addition to UA Doppler measurements throughout the pregnancy, in healthy Karya ewes.…”

“…The technique is applicable after the 25 th day after mating via the transrectal approach, but provided that soft faeces are present, a higher percentage of false negative diagnosis could be obtained. Some researchers report that the accuracy of Doppler ultrasonography for detection of pregnancy via the transrectal or transcutaneous approach was higher during the second or third gestation months (Lindahl, 1971;Wani, 1981;Watt et al, 1984;Serin et al, 2010). After using Doppler ultrasonography for pregnancy detection in goats, Wani et al (1998) reported accuracy of 100%, 100% and 72%, for foetal heartbeats, umbilical artery and median uterine artery, respectively.…”

SummaryKaradaev, M., 2015. Pregnancy diagnosis techniques in goats -a review. Bulg. J. Vet. Med., 18, No 3,[183][184][185][186][187][188][189][190][191][192][193] Several techniques for pregnancy diagnosis in goats are developed. Some of them are efficient and applicable in the field, but not enough accurate. Others are outlined with a high precision, but require equipment and specialised skills. Laparoscopy, laparotomy and vaginal biopsy are accurate but invasive and thus, inappropriate for the routine practice. Abdominal inspection, transabdominal palpation and increased live weight could be indicative for pregnancy in goats but they are reliable only after the second half of gestation. Udder examination and palpation are of low accuracy and their independent application for pregnancy diagnosis is not suitable. Blood, milk and faecal progesterone assays could indicate pregnancy in goats after the 21 st post insemination day until the end of gestation. The detection of pregnancy associated glycoproteins (PAGs) in blood plasma or milk samples is an early pregnancy marker but requires laboratory equipment. Non-return to oestrus is a cheap, practical and widely used method for detection of pregnancy between post insemination days 17 and 21 and does without signs of oestrus are assumed to be pregnant. A-mode, B-mode and Doppler ultrasonography are alternative methods for pregnancy diagnosis. Their accuracy and practical application potential are different. The two-dimensional ultrasound is one of the most appropriate methods for pregnancy diagnosis in goats. The accuracy of the method is about 100% on post insemination day 25-30 using the transrectal approach, whereas via the transabdominal approach, this accuracy is attained between the 40 th and the 45 th day.

Ultrasonography is a non-invasive, fast and accurate method for early pregnancy diagnosis (Yotov, 2020), monitoring of the embryofetal development (Bartlewski et al., 2000), estimation of fetal number and sex (Karen et al., 2009;Santos et al., 2007), determination of changes in reproductive organs (Atanasov et al., 2012) and mammary gland (Fasulkov et al., 2018) in ruminants.In goats, B-mode ultrasonography is mainly used for diagnosis of early pregnancy, monitoring of embryo-fetal development,
