The vaccine for rabbits from myxomatosis and VGHK will significantly protect the livestock population from the epidemic and facilitate the life of the rabbit. What is myxomatosis and how the enigmatic acronym VGHK is deciphered?
Symptoms in Myxomatosis Rabbits
Myxomatosis is a viral disease. It is transmitted from a sick animal to a healthy one. But where do you get sick if all the rabbits in the farm are healthy? The disease is transmitted by parasites that are on the body of the rabbit. These are fleas, lice, various shersteids and pukhodey. You can put them in a cage with hay or a litter pad. Because of insect bites, the virus is transmitted, and the animal is ill.
However, even taking only cleaned litter, and feeding rabbits only with granulated food, rodents can still fall ill, as the carriers of the disease are mosquitoes.
An outbreak can occur at any time of the year, ignoring seasonal carriers. The virus itself is resistant to low temperatures, so winter is not an obstacle to it.
Myxomatosis is a dangerous disease for both domestic rabbits and wildlife. If you do not start treatment on time, the ill animal will soon die.
Major symptoms include suppuration over the ages, body temperature up to 42 degrees, and general animal lethargy. The diseased rodent practically does not move, it is inhibited. In the ears and paws, nodules may appear, breathing becomes heavy, hoarse.
Disease occurs in two forms:

There is no cure for this disease, but it can and must be prevented by the vaccination done by the rabbit from the age of 28 days. By this time the animals are still too small, they may not tolerate the effects of the vaccine. In the body of the rabbit, live, but artificially weakened viruses are introduced. Thus, rabbits produce immunity to the disease. It is forbidden to inoculate already diseased animals, it is senseless. Germs during pregnancy and lactation should also not be inoculated. The weight of the rodent at the time of vaccination should be at least 500 grams.
There is a rabbit vaccination scheme from myxomatosis that should not be discarded in order to avoid an outbreak of the disease. For each rabbit, you need to create your own vaccine journal in order not to confuse the time of vaccination. The first vaccine is administered at 28 days of age if the young is gaining at least 500 grams. If the rabbit weighs less, the vaccine is postponed until the proper mass set time. Before vaccination, weighing the young is carried out. Then the young animals are inoculated after 3 months.
If there are no outbreaks of myxomatosis in the rabbit breeding area, revaccination of adult animals can be done every 12 months;if the outbreaks sometimes occur, then every 9th. For revaccination, it is best to choose spring or autumn, because the virus is especially active during this period, but if the time for another vaccine comes in another season of the year, it is not worth ignoring it, the rabbit needs to be inoculated.
All animals must be treated from internal parasites before vaccination. If the rabbit is infected with helminthis, it is weakened, so it may not be possible to delay the vaccination. The best treatment for parasites is to start 2 weeks before the expected vaccination.
Vaccinations can be done in 3 ways:
You can not slaughter animals with one needle, each rabbit must have its own disposable needle. If a needle-free nozzle is used, it should be handled in accordance with the instructions supplied with it. The injection site is disinfected with 70% alcohol.
The vaccine is prepared as follows: in natural.solution of the required volume( 0.2 ml with intradermal administration, 0.5 ml - with subcutaneous and intramuscular), a powder is added per dose.
Prepacked vaccine should be used within 1 hour.

Effectiveness of vaccination and complications after vaccination

Rabbit vaccination protects against an outbreak of the disease by 100%, if the breaks are not violated. The drug should be stored in the refrigerator from 0 to +5 degrees, as recommended by the instruction. It is not possible to use the drug after expiry date, it becomes ineffective.
Some rodents may be infected after being vaccinated.
If the injection site is not treated, there may be superimposition. Therefore, be sure to handle the injection site with 70% alcohol and use sterile needles.
If the rabbits were not treated from internal parasites, but infected with worms, an allergic reaction to the drug may occur.
May also develop myxomatosis in a mild form, unless a control weighing has been performed and have been vaccinated by individuals who weigh less than 500 grams.
Virus hemorrhagic disease of rabbits
This is a very rapid disease. The incubation period of VGHK is from several days to several hours.
often occurs asymptomatic. Cartilage dogs do not always have time to notice the symptoms, the disease kills rapidly. Sometimes, leaving the healthy rabbits in the evening in the rabbit, morning rabbit finds already dead animals. However, if the immunity is strong in rodents, the rabbit can notice the following symptoms: fever, refusal of animals from food and drink, general lethargy, mucous discharge from the nose, and blood from the anus.
To vaccinate all animals between the ages of 2 months and 6 years. At the age of 2 months, rabbits are resistant to the disease, and after 6 years of signs of disease in adult individuals was not detected.
The vaccination scheme is as follows:
- 1 vaccine - the age of rabies should not exceed 2 months, the best vaccination age is 45 days;
- 2 vaccine - the age of the animal is 4.5-5 months;
- 3 vaccines - six months from the previous one. The following vaccinations are given to animals every six months.
What should I do if an adult rabbit was bought and nothing is known about the condition of his vaccine? You need to inject the rodent as soon as possible! It is best to use a complex vaccine in this case, it is called combined. The drug protects the animal from myxomatosis and viral hemorrhagic disease.
Keep the liquid vaccine at temperatures from +2 to +5 degrees. If storage is carried out at home, then the most optimal place is the refrigerator door. If the defrost is supposed to be defective, the vaccine should be translated. Even a small effect of heat can cause damage to the drug.
A dry vaccine in a capped ampoule can be stored in a warm room.
At the time of vaccination, all animals should be healthy and treated with parasites, otherwise infection may occur and animals will die. Even healthy rabbits can fall ill after the injection. Approximately 4 rabbits from each 1000 individuals become ill and die after vaccine administration. You can not scrape rabbits during pregnancy and lactation. It is better for males to administer the vaccine to the anticipated bundle, even if the term of vaccination has not yet come up.
