Abstract
Mast geese are a native geese species originating from Germany. It is recorded as a fast growing geese species. Mast geese have white feathers, large body, orange beak and pinkish feet. The skull bones of poultry differ from those of mammals in that they are fused, the head is lightened by pneumatisation, has movable joints, and has two very large orbits. The aim of this study is to investigate the gross anatomy and CT imaging of the skull of the German Mast Goose in detail and to determine whether there is a sex difference. It is also expected to provide a literary contribution to further studies on this species or other poultry species. In our study, mandibles of 10 female and 10 male German mast geese (Anser anser), 5-6 months old, which reached slaughter weight (mean 6-7kg), were used. The craniums of the geese prepared for measurement were measured according to the osteometric measurement points. German mast geese skulls were scanned with a 64-slice Siemens computed tomography device at 80kV, 200MA, 639mGY and 0.625mm slice thickness. Morphometric measurements and correlation analysis of German mast skulls are given in Table 2 and Table 3. CGL and MGL measurement parameters were found to be statistically highly significant between females and males (P<0.01). GB parameter was found to be statistically significant between females and males (P<0.05). MGL measurement parameter has positive correlation with other measurement parameters (P<0.01). In this study, the comparative anatomy of the skulls of males and females of German mast geese of the genus Anser anser was analysed and imaged by CT, which is of great importance among the current diagnostic methods.
