A prospective study on vertebral fractures in newborn calves is described. Vertebral fractures were found in 7.0% of necropsied calves of the Danish Holstein-Friesian (SDM) and Red Danish Dairy (RDM) breeds. Cases were not found in submitted calves of the Jersey breed or beef breeds. At least in beef breeds this was probably due to the low number necropsied. The rate of vertebral fractures in SDM and RDM breeds and between males and females were similar. Most cases occurred in calves born by heifers, and manual traction force had been applied in all cases. All fractures which in most cases consisted of a simple epiphysiolysis were located at the thoraco-lumbar area, and especially the posterior epiphysis of T13 was afflicted.
本文描述了一项关于新生犊牛椎体骨折的前瞻性研究。在丹麦荷斯坦 - 弗里生(SDM)和丹麦红牛(RDM)品种的剖检犊牛中,发现椎体骨折的比例为7.0%。在提交剖检的泽西品种犊牛或肉牛品种犊牛中未发现病例。至少在肉牛品种中,这可能是由于剖检数量较少。SDM和RDM品种以及公母犊牛之间的椎体骨折发生率相似。大多数病例发生在初产母牛所生的犊牛中,并且所有病例均施加了手动牵引力。所有骨折(大多数情况下为单纯的骺离骨折)均位于胸腰段区域,尤其是T13的后骨骺受累。
