Evaluation of radiological and anatomical features of skull bones in adult Saanen goat

Abstract

AbstractBackgroundObtaining accurate knowledge of the anatomical structure of the skull helps in ontogenetic studies and determining sexual polymorphisms.ObjectivesThis study uses anatomical dissection and radiography to develop a size standard for the skull of the Saanen goat; information that will be applied to clinical evaluation and decision‐making.MethodsA total of 14 adult Saanen goat skulls (7 male and 7 female goats) were taken from the slaughterhouse and transferred to the clinic of the Faculty of Veterinary Medical Teaching Hospital, Urmia University, Urmia, Iran. Radiographs of each skull were prepared in the dorsal–ventral, left and right lateral recumbency. These heads were then brought over to the anatomy department, where the chosen morphometric traits were assessed and their means recorded.ResultsAccording to the findings of this study, the dorsal view of the skull revealed an incisive raphe and a widespread foramen of the nose. In the ventral view, the incisive bones were observed in the most cranial region of the skull. The base of the occipital bone was relatively large, and the jugular process was well‐developed. In the lateral view, the incisive bone was extended to the cranial and had a narrow process on the dorsal surface. Regarding infra‐orbital foramen, it was visible in the maxillary bone. Moreover, the lacrimal bone was perceived as a distinct bone.ConclusionThe precise standards acquired in this study can be utilized to interpret the findings and make clinical decisions about the normal and abnormal size of the bones that make up the skulls of the Saanen goats.
