Castration Castration of the male is done with a standard canine approach, a midline incision is made anterior to the scrotum. The testicles are pushed into the incision wound, and castration is via the open method. The inguinal ring must be closed to avoid post-operative herniation of the abdominal contents. The skin can be closed with an absorbable material, using either a subcuticular or simple interrupted suture pattern. After surgery the rabbit is given a single antibiotic injection.
Further antibiosis is unnecessary.
The rabbit should be allowed to recover in a warm environment, and allowed access to food and water. If indicated suture removal is done 10 days after the surgery. Residual stored sperm should be gone by this time. The average time for all such behaviour to have gone is two months. It may however be up to four months in larger breeds.
