How to treat subcutaneous ticks in piglets? - briefly
Administer a systemic acaricide (e.g., ivermectin or doramectin) at the label‑recommended dose for piglets, and inspect the skin daily to surgically extract any remaining embedded ticks. Maintain strict hygiene and environmental control to reduce reinfestation risk.
How to treat subcutaneous ticks in piglets? - in detail
Subcutaneous tick infestations in piglets require prompt identification, precise removal, and targeted therapy to prevent tissue damage and secondary infections.
First, conduct a thorough physical examination. Palpate the skin for firm, dome‑shaped nodules, especially along the neck, shoulders, and flanks. Use a bright light and magnification when necessary. Record the number, size, and exact location of each lesion.
Second, extract the parasites. Apply a local anesthetic (e.g., lidocaine 2 %) to the area to reduce piglet stress. Make a small incision with a sterile scalpel over the nodule, then grasp the tick with fine forceps and pull it out in a steady, straight motion to avoid tearing the mouthparts. Close the wound with a single absorbable suture or apply a sterile adhesive strip.
Third, administer systemic medication. A single dose of an injectable macrocyclic lactone (e.g., ivermectin 0.2 mg/kg body weight) effectively kills residual larvae and prevents further migration. For severe cases, combine with a short course of an injectable tetracycline (e.g., oxytetracycline 20 mg/kg) to control bacterial contamination.
Fourth, provide topical care. Clean the incision sites with a dilute chlorhexidine solution (0.05 %). Apply a broad‑spectrum antiseptic ointment containing bacitracin or neomycin twice daily for three days. Monitor for signs of inflammation or abscess formation.
Fifth, implement environmental control. Remove debris, replace bedding weekly, and treat the pen with a residual acaricide (e.g., permethrin spray at 0.5 % concentration) according to label instructions. Rotate grazing areas to break the tick life cycle.
Finally, establish a surveillance protocol. Inspect all piglets weekly for new nodules, record findings, and adjust treatment intervals based on infestation intensity. Maintaining consistent observation, proper wound management, and strategic chemoprophylaxis ensures rapid resolution and minimizes long‑term health impacts.
