Abstract

Congenital deformities of the lower limb were observed in 2 calves from different properties. One was a newborn Holstein-Friesian bull calf with polydactyly and polypodia of the right fore-limb. The other was an 8-month-old Friesian/Jersey crossbred heifer calf, which had a mirror image duplication of the plantar/palmar half of the distal portion of the digits. The abnormalities in the second calf have not previously been described in cattle. This paper presents details of the clinical, radiological and necropsy findings in these 2 calves.

摘要

在来自不同养殖场的2头犊牛中观察到先天性下肢畸形。一头是新生的荷斯坦-弗里生公牛犊，右前肢有多指和多趾。另一头是8个月大的弗里生/泽西杂交小母牛犊，其指（趾）远端跖侧/掌侧半部呈镜像重复。第二头犊牛的这种异常情况在牛中此前尚未有过描述。本文介绍了这2头犊牛的临床、放射学和尸检结果的详细情况。
