Two of three caprine triplets caused dystocia due to malformed forelimbs. This malformity was caused by radial agenesis and ulnar hypoplasia. Other congenital anomalies were also present. The influence of diet versus genetics could not be ascertained. Bilateral ulnar fractures in one kid revealed histologically rounded fracture ends with prominent periosteal new bone formation.
三只山羊三胞胎中有两只因前肢畸形导致难产。这种畸形是由桡骨发育不全和尺骨发育不全引起的。还存在其他先天性异常。无法确定饮食与遗传的影响。一只小羊的双侧尺骨骨折在组织学上显示骨折端呈圆形，有明显的骨膜新骨形成。
