In which food animal species is lidocaine commonly used for local anesthesia?

• A. Cattle
• B. Goats
• C. Sheep
• D. Swine

Answer: (D)

Lidocaine is commonly used for local anesthesia in swine due to its effectiveness in providing pain relief and its rapid onset of action, which is crucial during surgical procedures or for minor interventions. In swine, lidocaine can be used for procedures such as castration or dehorning, where localized pain management is essential for the animal's welfare.

The use of lidocaine in swine is well-established, and given their size and sensitivity, effective anesthesia is essential to minimize stress and pain during routine management practices.

While lidocaine may also be used in other food animal species like cattle, goats, and sheep, its prominence and frequency of use in swine stand out in veterinary practices, especially where swift movements and handling are needed during procedures. This makes it a preferred choice among veterinarians while working with this species.
