“…Sheep were among the first animals to be domesticated by humans, and the domestication process led to significant morphological and anatomical changes in the animals' head and body structures over time. These changes gave rise to variations within the same species, with gender being one of the factors influencing these variations (Can, et al, 2022). Different breeds of animals are frequently identified and described using osteometric criteria (Acosta et al, 2018;Hanafi et al, 2021).…”

The increasing demand for animal protein, particularly meat, requires a thoughtful approach to selecting the type of meat-producing animal to achieve maximum yields. This is crucial to maintain food security. This study aimed to evaluate and compare some skull osteometries. A total of 60 each of Balami, Uda, and Yankasa sheep (30 adult males and 30 adult females) were used in this study. The skulls were macerated using a hot water technique. Then 7 parameters were measured using a digital Vernier caliper. The obtained data were analyzed using ANOVA (p < 0.05). The result of this study was that the mean foramen magnum height (FMH) was highest, medium, and lowest in the Balami (2.1 ± 0.1 cm), Uda (1.9 ± 0.1 cm), and Yankasa (1.8 ± 0.0 cm) breeds, respectively, and vice versa in the foramen magnum index (FMI). The foramen magnum width (FMW) was similar in Balami and Uda but higher than in Yankasa (1.8 ± 0.1 cm). The FMH, FMW, and FMI were similar within sexes of the same breeds in Balami, Uda, and Yankasa. The mean dental length (DL), oral palatal length (OPL), and length of the upper molar row (LUM) were highest and lowest in Balami and Yankasa, respectively, while the mean length of the upper premolar row (LUP) was highest and lowest in Balami and Uda, respectively. The (DL), (OPL), (LUM), and (LUP) were higher in males than females in Balami and vice versa in Uda and Yankasa. In conclusion, craniometric values, including foramen magnum and dental osteometry, of indigenous Nigerian sheep breeds were used to compare them to other breeds and among themselves. It could also guide oral surgery and assist in identifying sheep breeds through comparative study.

This study was carried out to make was to determine the craniometric characteristics of the crania of Akkaraman and Kangal Akkaraman sheep, local breeds of Turkey, by using computed tomography (CT). Equal numbers of healthy male Akkaraman and Kangal Akkaraman sheep heads aged 8-12 months were used in the study (n=12/group). The images were obtained by scanning the heads with a CT device. These images were converted into a three-dimensional structure using the 3D Slicer program and their morphometric measurements were calculated. In the study, a total of 13 parameters and 5 indexes were measured in the skull. As a result, the morphometric differences of the skulls of Akkaraman and Kangal Akkaraman sheep were determined by statistical methods. All the characteristics examined were expressed as mean ± SE. Results of our study, when the craniometric data were examined a statistically significant difference was found in skull length, skull width, greatest length of the nasal bone, greatest breadth across the nasal, medial frontal length, cranial width, facial width, height of the foramen magnum, greatest breadth of the foramen magnum, greatest frontal breadth and least breadth between the orbits parameters (P 0.05). It is thought that the presented study may be useful to veterinarians in the fields of surgery and clinical practice, and to studies in the field of zooarchaeology, as well as sheep taxonomy.

Materyaller üzerinde kullanılan araçlar ile uzunluk, açı gibi parametrelerin ölçüldüğü ve sonuçların istatiksel analizini kapsayan yöntem morfometridir. Morfometrik yöntemler şeklin konu edinildiği birçok alanda ve çeşitli materyaller üzerinde uzun zamandır kullanılmaktadır. Sağlık bilimlerini konu edinen araştırma dallarında faydalanılan bu yöntem veterinerlik anatomisi alanında da sıklıkla kullanılmaktadır. Yaşanan teknolojik ilerlemeler ile morfometrik yöntemler de gelişmektedir. Morfometrik yöntem ile elde edilen ölçümlerin yanı sıra incelenen materyalin şekil yorumunun tamamen araştırmacının gözlemine dayalı olması bu yöntemi ampirik kılmaktadır. Geliştirilen son yaklaşım şekil analizine ve geometrik bilgilerin tamamının tutulmasına yaptığı vurgu nedeniyle geometrik morfometri olarak adlandırılmaktadır. Geometrik morfometrik incelemelerde indirekt yöntemler yardımıyla veri elde edilmektedir. Bu yöntemler üç boyutlu tarayıcıdan elde edilen görüntüler, radyografik görüntüler üzerinden yapılmakla birlikte en sık kullanılan yöntem fotoğraflama yöntemidir. Bu yöntemde verilerin saptanması için kartezyen koordinatları kullanılır. Bunun yanı sıra fotoğraflama metoduyla iki ve üç boyutlu incelemelerin yapılması mümkündür. Ayrıca bu yeni yöntem, çok sayıda şekil değişkenini bir arada incelemeye olanak tanırken analiz sonuçlarının grafiksel gösterimine de imkan sağlamaktadır. Morfometrik yöntemler ile şekil analizi, araştırmacının yorumuna dayalıyken geometrik morfometrik yöntemlerde bu analiz sonucunda daha kesin verilere ulaşmak mümkündür. Bu çalışmada, veterinerlik anatomisi alanında sıklıkla yararlanılan morfometrik ve geometrik morfometrik yöntemlerin kıyaslanması ve bu yöntemlerin kullanılmasının ne gibi farklılıklar yarattığını ortaya koymak hedeflenmektedir.
