A retrospective study of bovine mandibular fractures was conducted. An increased incidence in males, beef breeds and animals less than one year of age was identified when the study group of 17 was compared to the total bovine case load. Manipulation during dystocia was the most common cause of fractures. Four neonates had rostral mandibular fractures. Fractures caudal to or involving the premolars were restricted to animals over a year of age.Treatment was attempted in ten of the seventeen cases, with euthanasia or slaughter elected in the remaining seven cases. Of the five cases treated by internal fixation, all four neonates died from conditions related to septicemia.
对牛下颌骨骨折进行了一项回顾性研究。当将17只的研究组与牛的总病例数进行比较时，发现雄性、肉用品种以及年龄小于一岁的动物发病率增加。难产时的操作是骨折最常见的原因。4只新生牛有下颌前部骨折。磨牙后或累及前磨牙的骨折仅限于一岁以上的动物。17例中有10例尝试进行了治疗，其余7例选择了安乐死或屠宰。在通过内固定治疗的5例中，所有4只新生牛均死于与败血症相关的疾病。
