“…For the same reason, it can be assumed that the observations of Korkmaz and Emsen (2016) about birth weight and survival rate of lambs, may be related to more efficient vascular adaptations in crossbred animals. Such adaptations could be anatomical (larger diameter of vessels) or functional (earlier reduction of the RI) that could result in more blood reaching the fetus.…”

The aim of this study was to evaluate the blood flow of the uterine artery, fetal aorta and umbilical artery in the physiological pregnancy of sheep by means of pulsed Doppler throughout the gestational period. Thirty Santa Inês ewes weighing between 45.4±4.3 kg and aged 2 to 5 years were selected. The evaluations were carried out weekly from the 3 rd to the 21 st gestational week. Peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) were obtained. Analysis of variance was performed, and the minimum significant comparison of means was obtained by the BH test with adjusted P<0.05. The results were expressed as mean ± standard error. For the fetal aorta, there was an increase in the EDV values and a decrease in the PSV and RI throughout pregnancy. For the uterine artery, PSV and EDV did not present significant variation, whereas the RI showed a reduction in the last week. Increased EDV values were found for the umbilical artery throughout pregnancy. For the PSV there was no significant difference, as the RI was reduced at the end of pregnancy. The results obtained are expected to contribute to a more complete understanding of the hemodynamic changes resulting from pregnancy.

“…It has been reported that Romanov sheep reported to be characterised by an extremely long season of sexual activity and early sexual maturity, which were favoured by breeders to shorten the mating and thus production interval and increase annual election progress (Şen, 2020). In Turkey, pure breeding (Kutluca Korkmaz & Emsen, 2016) is carried out in the Eastern Anatolia Region, which has the closest climatic characteristics to the natural living conditions of Romanov sheep. In addition, it has been recorded that breeding is carried out in a total of 12 provinces in Turkey (Kandemir & Taşkın, 2022).…”

BackgroundWith the development of technology, 2D images have left their place for 3D models. The 3D modelling technique is widely used in plastic surgery, orthopaedic surgery, neurosurgery, traumatology, dentistry and medical education. The skull is important in terms of containing the starting parts of systems with vital functions.ObjectiveThe aim of the study is to reveal the difference between male and female and other species by 3D (three‐dimensional) modelling and craniometric measurements of Romanov heads.MethodsIn our study, skulls of Romanov sheep (10 females and 10 males) older than 1‐year‐old were used. The heads of Romanov sheep were scanned with computed tomography and modelled in 3D.Results and ConclusionsIn the study, it was determined that there was a statistically significant difference between male and female sheep in terms of the largest nose length, facial width, molar row length, viscerocranium length, and foramen magnum height parameters (p < 0.05). It was determined that the greatest width of the foramen magnum measurement parameter and the skull index showed statistically significant differences between the genders at the p < 0.01 level. No statistically significant difference was found in other measurements (p > 0.05). The data obtained as a result of the study will help in the racial discrimination and classification of bones obtained from zoo archaeological excavations.

“…The breed is known for its high fertility and skin with hair characteristics and is characterized by having a black‐grey body colour and short head‐legs and tail structure. The breed has been started to be bred in regions with climatic characteristics closest to their habitat conditions in Turkey (Akçapınar, 2000; Kutluca Korkmaz & Emsen, 2016).…”

Abstract2D images view hardly measurement points due to the overlap of anatomical features. This challenge is overcome by 3D modelling. In particular, images obtained by computed tomography are converted into 3D models through certain software. In sheep breeds with high polymorphism, some changes have occurred in their morphology due to both environmental and genetic factors. In this context, determining the osteometric measurements of sheep and revealing breed‐specific characteristics provide very important data for forensic, zooarchaeological, and developmental sciences. Mandibular reconstruction measurements are used to reveal differences between species and between sexes and for treatment and surgery in many fields of medicine. In the present study, morphometric characteristics were determined by 3D modelling from computed tomography images obtained from mandibles of Romanov ram and ewe. For this purpose, mandibles of 16 Romanov sheep (eight females and eight males) were used. They were scanned using a 64‐detector MDCT device at 80 kV, 200 MA, 639 mGY, and 0.625 mm slice thickness. CT scans were recorded in DICOM format. Reconstructions of the images were made using a special software program. Volume and surface area measurements were made with 22 osteometric parameters of the mandible. GOC‐ID had a statistically significant positive correlation with GOC‐ID, PC‐ID, GOC‐MTR, GOC‐PTW, GOC‐FMN, PMU, MDU, PDU, DU, GOV‐PC, GOV‐IMD, MTR‐MH, MO‐MH, FMN‐ ID, BM, MG, and CG (p < 0.01). GOC‐ID had a statistically significant correlation with MTR‐ID, GOV‐CR, PTW‐MH and SI (p < 0.05). When the CR‐PC measurement point was examined, it was observed that it had no statistically significant correlation with all measurement points (p > 0.05). As a result of the measurement, it was found that the volume and surface areas were higher in rams than in ewes. The morphometric data obtained would be a reference income in the fields of zoo‐archaeology, anatomy, forensics, anaesthesia, surgery, and treatment.
