In 2001, a letter to the editor of Veterinary Record from a highly experienced equine practitioner suggested that horses experience little or no pain after castration and questioned the routine administration of postoperative analgesic medications for all equine castrations.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used analgesic agents in equine medicine.

Pain management in food and fiber producing ruminants is often more problematic than in other domestic species.
