Abstract

This study has so far been the first attempt to characterize and quantify skull sexual variation in Kangal dog, by means of geometric morphometric techniques. A sample of 16 adult Kangal crania has been analyzed with this purpose. To obtain a full image of morphological pattern, digital pictures were taken from the ventral, left lateral, and dorsal sides of each skull, and a total of 16, 15, and 16 landmarks respectively were obtained on each image. Skull size and shape differed significantly in all aspects among different sexes, male skulls being bigger. Shape differences were observed mainly on zygomatic arch and muzzle on the dorsal view, pterygoid bone and articular surface to mandibular condyle in the lateral aspect, and cranial width and maxillary bone on the ventral view. Although the sample was comparatively small in number, being the first geometric morphometric approach applied on the Kangal dog, the obtained results will add vital information particularly to understand the cranial shape sexual dimorphism of this unique dog breed in Turkey.

土耳其坎加尔犬头颅大小和形状的两性二态性

到目前为止，这项研究是第一次尝试用几何形态测量技术来表征和量化坎加尔狗的头骨性别差异。为此目的，对16个成年袋鼠颅骨样本进行了分析。为了获得形态学模式的完整图像，我们从每个颅骨的腹侧、左外侧和背侧分别拍摄了数字图像，每张图像上分别获得了16、15和16个地标。不同性别间颅骨大小和形状各方面差异显著，男性颅骨较大。在背侧观上主要观察到颧弓和口鼻的形状差异，在侧面观察到翼状骨和关节面与下颌髁的形状差异，在腹侧观上主要观察到颅宽和上颌骨的形状差异。虽然样本数量相对较少，但作为第一个应用于坎加尔犬的几何形态计量学方法，所获得的结果将增加重要信息，特别是了解土耳其这种独特犬种的颅骨形状性别二态性。

期刊介绍： The Turkish Journal of Veterinary and Animal Sciences is published electronically 6 times a year by the Scientific and Technological Research Council of Turkey (TÜBİTAK). Accepts English-language manuscripts on all aspects of veterinary medicine and animal sciences. Contribution is open to researchers of all nationalities. Original research articles, review articles, short communications, case reports, and letters to the editor are welcome. Manuscripts related to economically important large and small farm animals, poultry, equine species, aquatic species, and bees, as well as companion animals such as dogs, cats, and cage birds, are particularly welcome. Contributions related to laboratory animals are only accepted for publication with the understanding that the subject is crucial for veterinary medicine and animal science. Manuscripts written on the subjects of basic sciences and clinical sciences related to veterinary medicine, nutrition, and nutritional diseases, as well as the breeding and husbandry of the above-mentioned animals and the hygiene and technology of food of animal origin, have priority for publication in the journal. A manuscript suggesting that animals have been subjected to adverse, stressful, or harsh conditions or treatment will not be processed for publication unless it has been approved by an institutional animal care committee or the equivalent thereof. The editor and the peer reviewers reserve the right to reject papers on ethical grounds when, in their opinion, the severity of experimental procedures to which animals are subjected is not justified by the scientific value or originality of the information being sought by the author(s).
