Affected fetuses display extreme disproportionate dwarfism, reflecting abnormal cartilage development (chondrodysplasia). On physical examination, defects compatible with disproportionate dwarfism were seen, such as shortened and rotated members, thickening of joints of the limbs, rounded big head, short snout, brachygnatia and kyphosis. © 2008-2020 ResearchGate GmbH.

Parturition. Ring womb/incomplete cervical dilation was found to be the most common maternal cause resulting in dystocia. Twenty-seven of 110 lambs born were affected, occurring as singletons, twins or one of a pair of twins. Histopathologically, immature chondrocytes were present at the articular surface and defective epiphyseal plates were detected in the extremities of the bones and sternum. Dexter cattle carry a genetic defect causing a dwarf phenotype in the heterozygotes (Dx+/-), while homozygotes (Dx+/+) are stillborn with extreme shortening of limbs and gross craniofacial defects and are described as 'bulldog' calves. In this study, we report three chondrodysplasic anomalous lambs obtained from 2 Akkaraman sheep with dystocia.

After fourteen days hospitalized, the animal died and X-ray examinations, necropsy and histopathology were performed. endprosthetic replacement.

With time, the TomatoH cells became evident at the SOC invagination site and cartilage canal, increased in number in the expanding SOC, and were present as mesenchymal lineage cells in the subchondral bone. The defect involved chondrocyte dysplasia, producing defective endochondral ossification and the presence of abnormal cartilage in the respiratory tract.
