Dystocia in camelids: The causes and approaches of management

Abstract

Dystocia in the camelids is rare, however the exceptionally long neck and the fetal extremities predispose to flexion of these as a common cause of dystocia. A prolonged (<2 hr) second stage of labor, bloody vaginal discharge or colic is the frequent sign of dystocia. The maternal causes of dystocia for camelids include uterine torsion, pelvic immaturity, uterine inertia and cervical dilation failure, whereas the fetal causes described are fetal malpostures and rarely fetal monsters like Schistosoma reflexus and Pero-somus elumbis or fetal dropsical conditions such as hydrocephalus. Dromedary camels must be restrained in a sternal recumbency for examination and vicious animals must be given xylazine (0.25 - 2.2 mg/Kg IM or IV). South American camelids may be restrained by using either xylazine or butarphanol (0.5 - 0.1 mg/Kg IM). Uterine torsion is much more common in llamas and alpacas whereas it is infrequent in the dromedary camel. The methods of dystocia correction by using mutations, fetotomy and cesarean section are described.
