Rare congenital absence of tail (anury) and anus (atresia ani) in male camel (Camelus dromedarius) calf

Abstract

A one-day old male camel calf was presented to the Al-Qattara Veterinary Hospital with complaints of  abdominal straining and lack of defecation. On examination it was found that the calf had no tail, the posterior  sacral margin was blunt and the anal opening was absent. The case was diagnosed as congenital anury with  atresia ani. The animal was sedated with 0.1 mg/kg of xylazine administered intramuscularly and under local  infiltration with 2% lidocaine a circular incision was made at the anal area to create an anal opening. The  animal passed plenty of meconium. The cut edges were sutured with horizontal mattress sutures. The animal was administered penicillin and streptomycin for 5 days and had an uneventful recovery. It is reported that  congenital anury rarely occurs in one humped camel and accompanied atresia ani can be surgically treated.
