I. Symptoms of scrapie in rabbit ears
The main symptoms of scrapie in rabbit ears are: The itching is unbearable, often scratching the ears with the forelimbs or shaking the head frequently. At the same time, the sick rabbits will also have symptoms such as poor spirit, irritability, anorexia, and weight loss. The signs are that the skin of the ears of the sick rabbits is red and swollen, dander and hair loss, and the infection range will continue to increase, and the skin of the affected area of the external auditory canal will be crusted and thickened. And because the rabbit keeps scratching the affected area, it often leads to aggravation of its skin infection, which can even cause fever, convulsions, epilepsy and other symptoms, and eventually loses its life.
II. Prevention and treatment of scrapie in rabbit ears
1. Expansion of infection control: scrapy rabbit ears It is a highly contagious disease. Once a rabbit in a rabbit group is infected, the whole group of rabbits may be infected by it. Therefore, once the owner finds an individual infected with ear itching, he must isolate it immediately to prevent cross infection.
2. Treatment of sick rabbits: prepare cotton wool and 2% trichlorfon, apply the cotton wool soaked with 2% trichlorfon directly on the affected area and around the infected rabbit, and apply 1 per day. For 3 consecutive days, intramuscular injection of ivermectin (dose: 0.2 mm/kg body weight) was performed for treatment, once a week, for a total of 3 times.
3. Do a good job of disinfection: because scrapie is caused by pathogens. Therefore, the owner needs to completely kill the pathogens in the environment, cut off the transmission route of the disease, and prevent the disease from spreading and causing repeated infection. In this regard, the owner needs to use 1% trichlorfon to spray the rabbit house and the surrounding environment once a week, continuously Spraying is used to completely eliminate pathogens in the environment, destroy the transmission route, and prevent transmission from expanding. Spray 1% trichlorfon once a week for 3 consecutive weeks; pay attention to secondary disinfection of uninfected rabbits, and thoroughly clean up the feces, hair and leftover feed of the rabbits in time.
4. Enhance the resistance of rabbits: scrapie is most likely to infect rabbits with weak constitution and low resistance, so the owner should pay attention to keeping the rabbit’s nutrition comprehensive and balanced, and pay attention to supplementing the rabbit when raising rabbits. Some vitamins and green feeds also need to be fed in moderation to maintain high resistance of rabbits.

For this reason, when the weather is hot, you must pay attention to ventilation and cooling of the rabbit house, and strictly do a good job of disinfection of the rabbit house to avoid the decline of the rabbit’s resistance.
