“…In this study, the GOV‐CR parameter was determined as 90.82 ± 0.95 mm in females and 93.50 ± 0.64 mm in males. Among the studies, this parameter was reported as 95.7 ± 27.1 mm in Mehraban sheep (Karimi et al, 2012), 94.20 ± 7.65 mm in Hemshin sheep (Dalga et al, 2017), 108.68 ± 2.36 mm in Hasmer sheep (Özüdoğru, İlgün, & Özdemir, 2019), 110.97 ± 2.95 mm in Konya merino (Özüdoğru et al, 2019b), and 109.86 ± 5.56 mm in Kosovo Bardhoka breed (Özkan et al, 2020). Yilmaz and Demircioglu (2019) stated in their study on gazelle mandible that there was a statistical significance between sexes in the GOV‐CR data; similar to Özkan et al (2020)'s study in the Kosova Bardhoka breed, it was determined in the present study that the GOV‐CR value did not have a statistical significant difference between sexes ( p > 0.05).…”

“…For this purpose, numerous studies have been carried out in the field of veterinary anatomy in order to reveal the differences between the sexes and within the species based on the measurements taken from the mandible (Dalga et al, 2017; Demiraslan et al, 2014; Özkan et al, 2020; Özüdoğru et al, 2019a, 2019b; Yilmaz & Demircioglu, 2019). Mandible reconstruction is used for treatment and surgery in many fields of medicine (Güzel et al, 2023; Yeter, 2021).…”

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.

“…Studies conducted on many different species and races using traditional morphometric methods are widely available in the literature Dalga et al 2022;Özcan et al 2010;Karimi et al 2011;Mohamed et al 2016;Dalga et al 2017;Dalga et al2018;Dalga and Aslan 2020;Wehausen and Ramey 2000;Dalga 2020;Jashari et al 2022;Gundemir et al 2020;Yılmaz and Demircioğlu 2020;Özüdoğru et al 2019). In addition to examining evolutionary processes, there are many studies that analyze two-and threedimensional images using the geometric morphometry method (Klingenberg and Marugan 2013;Szara et al 2022;Koçak et al 2023;Pares 2015;Fernandez et al 2023).…”

The aim of this study is to examine and analyze the mandible of Morkaraman sheep without any skeletal disorders using the geometric morphometric method. For this purpose, a total of 14 mandibles from male and female individuals were used in the study. The main components in multidimensional data sets were determined with Principal Component Analysis, used within the scope of the geometric morphometry method, and the differences between the samples were determined with Discriminant Function Analysis. Statistical and formal analyzes of these variances were also performed. A total of 12 principal components were obtained with 12 punctuations selected on a total of 14 mandibular (7 female, 7 male) images. Among these principal components, the first principal component (PC1) alone accounted for 30.409% of the total variation. The second principal component (PC2) alone accounted for 22.265% of the total variation, and the third principal component (PC3) alone accounted for 14.893% of the total variation. The first three of the variances obtained explained 67,567 of the shape differences. Discriminant Function Analysis (DFA) was used to objectively evaluate gender differences. In the discriminant function analysis, the p value was above 0.05 (p = 0.7). Although there was a complete separation between genders formally and statistically, no significant p value was obtained. In line with these analyses, information was obtained about the anatomical features and adaptations of the Morkaraman sheep mandible, which is one of the important economic resources of our country and is bred in a wide area, and it has become an exemplary study in this field.

Bu çalışma İvesi koyunlarında mandibula'nın morfometrik özelliklerini belirlemek amacıyla yapıldı. Bu amaçla 20 adet (10 erkek, 10 dişi) erişkin İvesi koyunu (Ovis aries) mandibulası kullanıldı. Bir bütün halinde temin edilen kafataslarının maserasyonu yapıldı, kas ve deri diseksiyonları tamamlandı ve temporomandibular bölgenin dezartikülasyonu ile mandibula' lar çıkarıldı. Mandibula' lar üzerinde 18 adet doğrusal ölçüm analizleri yapıldı ve tüm veriler ortalama ± standart sapma (SD) olarak ifade edildi. Yapılan incelemelerde dişi ve erkekler arasında GC-MAK (P<0.05) ve CR-PC (P<0.01) parametrelerinde istatistiksel farklılıklar gözlendi. Osteometrik ölçümler arasındaki korelasyon analizleri incelendiğinde veriler arasında P<0.05 ve P<0.01 değerinde istatistiksel önem tespit edildi. Elde edilen biyometrik verilerin hayvan modeli olarak koyun mandibala modellerinin kullanıldığı anatomik, klinik ve taksonomik çalışmalarda referans bilgi kaynağı niteliğinde biyometrik ölçüm ve sınırlar sunacağı düşüncesindeyiz.
