Breeding rabbits is a fascinating process that requires a little time and effort, as well as funds for the realization of your goals. But, as in any other farm, problems can arise in rabbit breeding that require immediate solution. Like other pets, rabbits suffer from characteristic diseases. Among the most common pathologies among these animals is the so-called viral hemorrhagic disease. It is worth noting that this disease is very dangerous for the life of rabbits, which means that it requires constant preventive measures against it. This article will tell you what steps you can take in case of illness and how to protect pets from it.
Rabbit viral hemorrhagic disease was first discovered in China in 1984. It was there that she received her distribution. In the USSR, the disease appeared in 1986-1987, and it is diagnosed to this day. Moreover, the virus is resistant to heat and cold and can persist even after the use of aggressive chemistry.
The disease quickly spreads and affects the body of rabbits completely, causing hemorrhages against the background of destructive tissue changes. Among the main causes of infection:
- poor nutrition;
- non-compliance with standards for the maintenance and care of rabbits;
- transmission of the disease by airborne droplets;
- defeat by absorption of infected feed;
- defeat through an infected habitat.
In the carcasses and skins of dead animals, the virus can persist for up to one hundred days. A decrease in immunity and cold can become prerequisites for the early infection of rabbits. What to do if rabbits have red urine in this link .
Rabbit viral hemorrhagic disease - an infectious, acute leaking highly contagious disease
Viral hemorrhagic disease can occur in two forms: acute and chronic. Acute disease usually occurs after stressful situations, as well as when infected healthy individuals with patients. In this case, the death of animals occurs in one to three days.
Chronic hemorrhagic disease, as well as pododermatitis , rhinitis and other infections, appears with improper care for rabbits. In this case, the first symptoms of progression are almost invisible and can be hidden by the incubation period. The development of the disease is fatal.

There are acute and chronic viral hemorrhagic rabbit disease
Symptoms of acute and chronic hemorrhagic rabbit disease vary. So, for the first form of pathology are characteristic:
- lethargy and weakness;
- an increase in body temperature above forty degrees;
- arrhythmia, palpitations;
- lung damage
- the development of abnormal processes in the gastrointestinal tract;
- bleeding from the mouth and nose.
In case of a chronic disease:
- conjunctivitis, purulent discharge in the eyes;
- runny nose;
- pneumonia, purulent pneumonia;
- pathology and disruption of the gastrointestinal tract;
- rectal bleeding;
- blue mouth.
Infected rabbits become lethargic and weak
The virus quickly penetrates the circulatory and respiratory systems, infects lymph and internal organs, changes cells and destroys capillaries, causing internal and external bleeding, as well as bruising.
If the first signs of hemorrhagic disease occur, you must immediately call a veterinarian. Despite the fact that an effective cure for pathology has not yet been developed to date, you can save the remaining rabbits. To do this, injections of a special serum are made to the whole livestock, which begins an active action in two hours. The likelihood of manifestation of the effectiveness of protection in this case is very high. Find out how to treat clogged goiter in chicken.
In the event that for some reason it is not possible to acquire and inject the animal with serum, the remaining rabbits must be killed by the bloodless method. After that, it will be necessary to wash and disinfect the inventory and premises for keeping rabbits. For this, bleach is also suitable. If, upon examination of the livestock, there are no signs of the disease, healthy rabbits can be quarantined. Infected animals are killed under any circumstances. Carcasses, as in rabies , will need to be destroyed (it is best to burn), and one or two of them should be sent for diagnosis.
A diagnostic study is carried out as follows: a blood sample is taken from the animal’s heart for examination. In the case of a correct diagnosis, you can identify the cause of the pathology and prevent the spread of infection. Having recovered young animals, it is not recommended to leave the offspring due to the lack of immunity. Also read about the Krasnogorbatovskaya breed of cows, read in this article .
Only a veterinarian can detect a disease in a rabbit by taking a blood sample from a heart for analysis
Upon detection of a problem, some breeders do not destroy the infected livestock, but use it for cooking. The hemorrhagic disease virus is not dangerous for humans, but it reduces the immunity of rabbits, which increases the likelihood of other infections that can cause harm to the breeder.
If the disease has already been detected in order to prevent the spread of infection, the following rules must be followed:
- do not sell rabbit meat and fur (temporary measure);
- refuse to export animals outside the farmyard or farm;
- do not vaccinate against pathologies other than hemorrhagic (due to weak animal immunity);
- Do not move and align animals together;
- change clothes and shoes after visiting rabbits with infected individuals;
- carry out injection treatment throughout the year;
- wash hands and shoes with the use of disinfectants.
In the event that infection has not yet occurred, it is necessary to carry out the vaccination procedure for rabbits. With the right approach, the likelihood of resistance to the virus will increase by more than ninety-five percent. Vaccinations of young animals are done as follows:
- The first vaccination should be done already at the age of one and a half months. Immunity in this case accumulates in just three days and remains stable for a year.
- When diagnosing an infection on a farm, vaccination is carried out only among healthy individuals who have not had contact with patients.
- Before the injection, it is necessary to treat the area with alcohol.
- Each injection is done using new needles.
- The presence of pronounced side effects after the introduction of the vaccine suggests that it is necessary to change the drug.
- Vaccination is necessary every nine months.
Quarantine after detection of the virus should last about a year. All this time it is necessary to constantly treat the premises and equipment from infections.
The importance of timely vaccination against HBV
The virus is a hemorrhagic disease, like stomatitis can be transmitted from the soil, from another animal, and even through the bite of a mosquito or wild rodent. Without systematic vaccination, if the virus enters the rabbitry territory, the animals will be doomed to death, and the remaining rabbits will be in quarantine for a long time. Currently, only timely vaccinations can protect breeders from losses. This material will tell about the treatment of pasteurellosis in rabbits.
- Hemorrhagic disease is very dangerous and in most cases with infection leads to death.
- Pathology spreads very quickly and requires urgent intervention by the breeder to prevent the spread of infection.
- In order to avoid the spread of infection, it is necessary to carry out systematic cleaning and disinfection of rooms and equipment.
- The best way to fight infection is a timely vaccination of HBV .
