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

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.Keywords: Anury, Atresia ani, Camel, Taillessness
