Analysis of possible reasons for dissolution of stallion after castration

Within the practical training of students of the fifth year of studies of veterinary medicine, a demonstration was performed of stallion castration. The owner of the horse decided to take this step because of the unpredictable temperament of the stallion. The castration was carried out under general anaesthesia. The stallion was laid down and immobilized for castration in keeping with the so-called in-the-field conditions. The castration proceeded without any complications, and the postoperative course was in order. Three days after castration, the horse died with symptoms of colic. The autopsy showed obturation of the ileum and ileocecal valve by Parascaris equorum parasites
