Myxomatosis in rabbits is a viral disease that is characterized by edematous gelatinous cellulose infiltration in the external genital area and head, serous-purulent conjunctivitis, and the formation of nodular tumors on the skin. The source of the causative agent of this infectious disease is sick or infected rabbits that spread the virus through secretions from the eyes and nose.
The main distributors of infection in nature are blood-sucking insects (mosquitoes, mosquitoes, fleas), as well as ectoparasites (ticks, lice), in the body of which the virus can stay for months. Myxomatosis affects any animal, regardless of gender, breed or age. The classical form is quite malignant and in 100% of cases has a fatal outcome. Mortality in nodular form is 70-90%.
No effective remedies have been found for controlling this rabbit disease. The only way to save the livestock is by timely vaccination with Rabbivak B.
The vaccine Rabbivak B is a dry and porous mass of beige and cream color. It is produced from live lyophilized rabbit myxomatosis virus, called strain No. B-82. It induces an immune response in rabbits lasting for 12 months 5-9 days after a single injection. It is forbidden to use the product on weakened or clinically sick animals. The product is used subcutaneously or intramuscularly in the back of the thigh, starting from 30-45 days of age. The volume of one dose is 1 cm3, in problematic areas, revaccination should be repeated after three months.
- The vaccine is harmless and areactogenic, does not possess medicinal properties.
- Rabbits from vaccinated rabbits up to 2 months have passive immunity.
- To achieve an effective result, the storage conditions of the vaccine must be observed. A dry and dark place with a temperature of 2-8 degrees is required.
- Any violations of the vaccination schedule are highly undesirable, as this can cause a decrease in the effect of immunization. In the case of missing the introduction of the product, it is necessary to immunize as soon as possible.
The rabbit's immunity depends on several factors: the conditions of feeding, the age and physiological state of the animal (lactation or pregnancy), the individual characteristics of the body, the presence of parasites, and much more.
When vaccinating, you must follow a few basic rules. It is necessary to exclude the introduction of the product to sick animals, as well as pregnant and lactating females. For a better formation of immunity, a balanced diet and treatment against parasites are important. Newly arrived rabbits should be quarantined.
The effectiveness of the vaccine in bacterial and viral diseases of animals is about 95-98%. In this case, the meat and skins of vaccinated rabbits are sold without any restrictions, regardless of the timing of vaccination. State authorities strictly monitor the quality and production conditions of vaccines, and the effect of the products is predictable and completely safe for animals and humans.
