Orchiectomy in the European brown bear

Facilities for captive holding of European brown bears (Ursus arctos) are usually limited in capacity and already filled. The brown bear is a protected species, reduction of free-living population is not allowed and protection of existing numbers is requested by international conventions. The best regulation of population in captivity is by orchiectomy because of surgical simplicity and efficiency. We achieved general anaesthesia by use of a combination of ketamine hydrochloride and xylazine hydrochloride applied intramuscularly in four treated males. Surgical procedure of orchiectomy was carried out by closed method using two skin incisions parallel to raphe scroti in one bear and prescrotal incision in the remaining 3 bears. Spermatic cord was ligated by a triple clamp technique. Skin incisions were sutured by simple interrupted pattern with absorbable suture material. Recovery from general anaesthesia was without side-effects after a mean duration of 172 min. Mean surgery time was 54 min. The surgical wounds healed “ per primam” .
