Although the predominant species found in poultry farming are galliforms and anseriforms there are few comparative studies referring to the skeletal morphology of these species. This study compares thoraco-abdominal component of these species in light of their different adaptation to the environment. The research was carried out in the Compared Anatomy laboratory of the Faculty of Veterinary Medicine of Cluj-Napoca. A total number of 6 skeletons, 3 chickens and 3 gooses were examined following comparative aspects of the anatomical structures relevant for this area. After examining the bones from the thoraco-abdominal region, differences as well as similarities between the two species of birds were observed. The thoracic cavity in chickens presented 7 pairs of ribs, of which 2 were asternal, while the same segment in geese contained a number of 9 ribs of which only 1 asternal. The sternum, presented 3 pneumatic holes in chickens and only one in geese. Also, differences were noted at the level of the sternal body, which was reduced in the chicken compared to the goose. On the lateral sides of the sternal body, the goose registers 7 or 8 costal indentations depending on the individual, compared to only 3 found in the chicken. The coxo-dorso-lumbosacral complex presented small differences between the two species. The iliac fossa in chickens is well defined, the pubis is oriented dorsally, slightly curved medially and the coccygeal vertebrae are 7 to 8 depending on the individual. In geese, the external iliac fossa is absent, the pubis is oriented ventrally, curved medially and the coccygeal vertebrae are 6, the pygostyle being fused to the last vertebrae.
