Pathogen and route of infection
The causative agent of psoroptosis is an oval yellowish tick (in Latin called Psoroptes communis var. CuniculiRaill.). It can reach a length of 0.5-0.8 mm. The tick settles directly in the auricle and can also penetrate the middle ear. The disease has the property of spreading very quickly, and when it is in a state of neglect, it can go to the brain in the form of a tumor and cause the death of the animal. The infected rabbit refuses mating with the male and her own offspring.
Infection occurs for several reasons. The most common are: contact between an infected animal and a healthy one, infection through household items or the work clothes of the owner. Diseases are most often affected by rabbits from 4 months. Young rabbits can also become infected by their mother.
There may also be causes of the disease: close keeping of rabbits with each other (crowded content), increased humidity and poor feeding.
In fact, the ear tick problem in rabbits is easily preventable. We will talk about this later.
Signs of the disease
A high probability of infection occurs in the autumn-winter period. The infected rabbit immediately feels discomfort, begins to shake his head, ears restlessly. The longer the disease progresses, the more often rabbits begin to scratch their ears and lose their appetite. When running a form with complications, the rabbit loses weight. His life is in jeopardy.
External signs of the disease are the resulting crusts that cover the inner surface of the ear (this is already an advanced stage of the disease). There you can find the bites themselves. Ears thicken and blush.
The first bell to the fact that the animal has an ear tick is red bumps or vesicles in the ears, which later burst. From there liquid flows and dries. In place of the bubbles, a crust then forms.
The detection of the disease can also be carried out using laboratory analysis, after which it is already necessary to proceed directly to treatment. This is done with scrapings for the presence of ticks and their eggs. Scraping can be done by yourself. To do this, you must have petroleum jelly, a scraping tool and a magnifying glass. Take the oil and heat it to 40 degrees, make a skin scraping and put it in the oil. Then take a magnifying glass and take a closer look. you can see the parasites themselves, if they are in the skin.
You can treat the ear tick in rabbits yourself or go to the veterinarian. Choose the most suitable method for yourself.
Treatment with folk remedies involves the use of vegetable oil and turpentine in a ratio of 2: 1. The mixture is filled into a syringe and washed throughout the ear cavity. If necessary, the procedure can be repeated after 2-3 weeks.
Camphor oil is also a good remedy. Unlike vegetable, it does not require additional additives. He is also taken into a syringe and sprinkled with oil on his ear. Treatment is good in the early stages.
If there are scabies in the ears, then it is recommended to displace glycerin and iodine in a ratio of 4: 1. Substances will soften them well. Treatment should be done every other day.
Medicines that help with treatment can be in the form of drops and injections. Drops of “Dekt” can be an excellent treatment option, they not only remove symptoms, but also destroy ticks.
Breeders also use various aerosols: chlorophos, neocidol, ciodrin, sulfidophosis. These tools have proven themselves very well in the fight against ticks. Spray the ear cavity at a distance of 10-15 cm with aerosols for 1-2 seconds.
Experienced rabbit breeders recommend using Butox 50 ampoules. They need to be bred in water and spray ears. The proportion to irrigation is one ampoule per liter of water. One ear is sprayed 2-3 times.
Avoiding psoroptosis is very simple. It is only necessary to disinfect cells, feeders, tools with antiparasitic agents. Keep new rabbits away from the previous ones in quarantine. Inspect the rabbits should be twice a month. And pregnant females should be treated even in the absence of obvious signs of the disease 2 weeks before the round.
