“…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.…”

“…В-mode (brightness) realtime ultrasonography is the most commonly used diagnostic imaging techniques for detection of pregnancy in small ruminants (Wani et al, 1998;Langfort, 2003;Kähn, 2004;Sousa et al, 2004;Gardon, 2005;Johnson, 2005;Yotov, 2007). It is a modern, non-invasive, rapid and accurate method for early detection of pregnancy in animals (Abdelghafar et al, 2007;Santos et al, 2007).…”

“…The separation of pregnant and nonpregnant does in different groups reduces the losses from abortions, stillbirths or giving birth to non-viable offspring and optimises labour, feed and medication costs (Wani et al, 1998). The utilisation of an accurate and easily applicable method for pregnancy diagnosis allows the timely repeated insemination, breeding or culling of non-pregnant animals (Amer, 2010).…”

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.

“…Audible signals, which may be distinguished by the observer, include the foetal heartbeat, arterial blood flow in the middle uterine artery and umbilical arteries, foetal body movement and maternal intestinal movement (Dawson 2002). Some researchers have reported that intrarectal and external Doppler ultrasonic examinations have a higher accuracy for diagnosing pregnancy in the second and third trimesters (Lindahl 1971; Wani 1981; Watt et al. 1984).…”

Contents Obstetric ultrasonography is the most common diagnostic approach used in veterinary reproduction because it is a simple, reliable and non‐invasive imaging technique. With advances in ultrasonography of small ruminants, assessment of pregnancy in goats is challenging for accurately managing reproduction. This article presents an up‐to‐date review of the use of ultrasonography in pregnancy for the diagnosis and evaluation of intrauterine foetal growth in goats.

Determination of embryonic and fetal age by transrectal and transabdominal ultrasonographic examination in Akkaraman ewesSummary: This study was performed in order to determine gestational age in ewes by fetometry. For this purpose, a total of 10 Akkaraman ewes were examined by using ultrasonography supported by a linear array transducer. In order to find an equation to calculate the gestational age (GA) by using fetometric method, the parameters of diameter of embryonic vesicle (EVD), crown-rump length (CRL), occipito-nasal diameter (OND), biparietal diameter (BPD), orbital diameter (OD), thoracic diameter (TD), cotyledon diameter (CD), transversal heart diameter (THD), stomach diameter (SD) and kidney diameter (KD) were calculated. At the end of the study gestation age equations was produced depending on correlations which were statistically significant. In this sense, As a result, it was shown that gestational age could be calculated by using these formulas. It was seen that OND, BPD, OD parameters were found to be most effectively 36-95 days to determine gestational age.
