兔螨病防治技术：伊维菌素注射与药浴疗法

Rabbit mange is a highly contagious ectoparasitic disease caused by Sarcoptes and Psoroptes mites parasitizing rabbit skin. Affected rabbits show intense itching, hair loss, and skin thickening with crusting, severely affecting growth and fur quality. Transmission through contact is extremely rapid; introducing one affected rabbit can infect the entire herd within a short time.

Rabbit mange has three main types. Ear mange caused by Psoroptes parasitizes the external ear canal; rabbits shake their heads frequently with abundant brown-black crusts in ears. Body mange caused by Sarcoptes spreads from nose and lips to the whole body. Foot mange parasitizes feet causing lameness.

Ivermectin is the drug of choice for rabbit mange treatment, injected subcutaneously at 0.2-0.3 mg/kg body weight, repeated at 7-10 day intervals; generally 2-3 injections achieve cure. Long-acting doramectin provides 28 days of effectiveness with a single injection, especially suitable for large-scale farms.

Medicated baths are suitable for group prevention and treatment. Use 1:1000 amitraz solution or 0.05% phoxim solution at 35-38 degrees Celsius. Ensure rabbits drink adequately before bathing; towel dry after and place in warm, ventilated areas. Prevent solution from entering eyes or mouth.

Environmental treatment is equally critical. During treatment, disinfect cages with flame guns to kill mite eggs; replace and incinerate all bedding. For whole-herd prevention, add ivermectin premix at 2 g/ton feed for 7 consecutive days.
