The combination of Telazol, ketamine, and xylazine is commonly used for injectable anesthesia in pigs due to its effectiveness in producing anesthesia while minimizing stress. Telazol, which contains tiletamine and zolazepam, is a dissociative anesthetic that provides sedation and analgesia. Ketamine also acts as a dissociative anesthetic and contributes to the overall anesthetic depth and analgesia. Xylazine, an alpha-2 adrenergic agonist, provides sedation and muscle relaxation, which is particularly beneficial in swine for achieving a calm and manageable state during surgical procedures.

This combination of drugs works synergistically to enhance the anesthetic effect while allowing for quicker recoveries compared to other injectable agents. It is crucial in veterinary medicine, especially for species that may not respond well to inhalant anesthetics or require rapid onset and reliable anesthesia for short procedures.

In contrast, the other options either do not reflect common practices in swine anesthesia or involve agents more typically associated with different species or methods.
