I. Causes of otitis media in rabbits
Poor feeding management, long-distance transportation, feed mutation, malnutrition, parasitic infection , the stocking density is too high, the rabbit house is cold, hot, humid or poorly ventilated, etc., will lead to the decline of the rabbit’s resistance, and at the same time, the bacteria will take advantage of the situation and cause infection. In addition, otitis media in rabbits can also be secondary to other diseases, such as tympanic membrane perforation, external auditory canal inflammation, influenza, infectious rhinitis, etc., which can cause inflammation of the tympanic cavity and ear canal. Pasteurella multocida is the main pathogen causing infection.
2. Symptoms and pathological changes of otitis media in rabbits
1. The clinical symptoms of simple otitis media are not easy to be found , torticollis in sick rabbits can be the main clinical symptoms of the disease, and the degree of torticollis in different sick rabbits is also inconsistent. If the rabbit suffers from unilateral otitis media, then the diseased rabbit mainly shows that the head and neck are tilted to the affected side, and the affected ear is facing down. called torticollis. If the patient suffered from bilateral otitis media, the sick rabbit showed the behavior of bowing its head and stretching its neck. Once the rabbit’s affected ear appears purulent, or purulent secretions flow out, the sick rabbit may also appear with symptoms such as elevated body temperature, depression, difficulty in eating and drinking, and dehydration. If the infection spreads to its meninges and brain, movement disorders and other neurological symptoms are most likely.
The course of otitis media in rabbits is very slow and can last for 1 year or more.
III. Treatment and prevention of otitis media in rabbits
1. Treatment
a, Anti-inflammatory treatment. Inject Baili injection once every two days (dosage: 0.13ml/kg), at the same time add 80g of ciprofloxacin hydrochloride to 100kg of water or add enrofloxacin soluble powder (200g of enrofloxacin soluble powder) to the feed of sick rabbits powder/per 100kg feed). For the local affected area, disinfectant can be used to clean it. After blotting dry with cotton balls
, ampicillin sodium or Baili injection is instilled into the ear of the sick rabbit, 2 times a day, for 5 consecutive days. At the same time, subcutaneously inject ampicillin sodium to the sick rabbits, the dose is 20 mg/rabbit, 2~3 times a day, and use it continuously for 5~7 days.
b. Strengthen neurotrophy. Subcutaneous injection of vitamin B1 and vitamin B12 each 0.05ml/kg.
2. Preventive measures
1. Treat the external auditory canal inflammation, influenza, rhinitis, conjunctivitis and other diseases in rabbits in time.
2. Inject rabbits with rabbit dual vaccine in early spring and early autumn every year, pay attention to cleaning and disinfecting the rabbit house daily, and take preventive measures in time.
This is the end of our explanation of the symptoms and pathological changes of rabbit otitis media. Rabbit otitis media is a serious disease. I hope the owner will pay attention to it and pay attention to the rabbits. Take precautions.
