How can subcutaneous ticks be removed from pigs? - briefly
Make a small incision with a sterile needle or punch over the embedded tick and extract it carefully using forceps. Apply a licensed acaricide to the wound to prevent secondary infection.
How can subcutaneous ticks be removed from pigs? - in detail
Removing embedded ticks from swine requires a systematic approach to minimize tissue damage and prevent secondary infection. The process begins with thorough inspection of the animal’s skin, focusing on areas where ticks commonly embed, such as the neck, ears, and ventral abdomen. Once a tick is located, the following steps should be executed:
- Restrain the pig securely to prevent movement; chemical sedation or physical confinement may be employed depending on the size and temperament of the animal.
- Administer a local anesthetic (e.g., lidocaine 2 %) around the bite site to reduce pain and reflexive twitching.
- Disinfect the surrounding skin with an appropriate antiseptic solution (chlorhexidine or iodine-based) to lower the risk of bacterial entry.
- Using a sterile, sharp scalpel or fine scissors, make a small longitudinal incision through the overlying epidermis, exposing the tick’s mouthparts.
- Grasp the tick’s body with a pair of fine-tipped forceps as close to the skin as possible, avoiding compression of the abdomen.
- Apply steady, gentle traction to extract the parasite in one motion; if resistance occurs, enlarge the incision slightly to free the mouthparts.
- Inspect the wound for remaining fragments; any retained hypostome pieces should be removed with the same forceps.
- Irrigate the site with sterile saline, then apply a topical antiseptic ointment and cover with a breathable dressing if extensive tissue loss is present.
- Monitor the pig for signs of infection, inflammation, or systemic reaction for at least 48 hours; administer a broad-spectrum antibiotic if clinical signs develop.
Preventive measures include regular acaricide treatments, environmental control of tick habitats, and routine body examinations during peak tick seasons. Proper record‑keeping of infestations and interventions supports herd health management and reduces recurrence.
