In ten years we may be left without milk and meat.
In the meantime, it is possible to save bovine animals now. How to do it?
The problem of leukemia has plagued specialists for many years. It is relevant even today. The situation is complicated by the fact that some breeders do not take the disease seriously. Hoping for “maybe”.
In recent decades, the disease has been recorded in almost all subjects of the Russian Federation. Damage is determined not only by the death of animals and the disposal of contaminated meat. Selection and breeding work is destroyed, animal life is reduced, milk quality and cow milk productivity are reduced. Just imagine that the negligence or inaction of some breeders determines what kind of “legacy” we will leave to future generations.
“Extensive work is needed to create a healthy herd of leukemia, “said Nurikhan Khabibov, head of the Birsk veterinary station.The disease is currently not completely curable. Killing infected cows and bulls is the only way to protect healthy animals from leukemia. The rules prohibit the mixing of animals from different herds during grazing and watering. Farm animals should be quarantined and tested for leukemia. Veterinarians receive blood samples from animals over six months old once a year.
Drugs that completely destroy the tumor virus have not been developed, but scientists around the world are trying to find an effective vaccine.
The insidiousness of the disease is that the animals do not show clinical symptoms of the disease for a long time. Externally, it is almost impossible to determine if a cow is sick. Sometimes obvious signs do not appear for a lifetime. A virus-carrying cow can be productive and produce high milk yields. Animals infected with leukemia often give birth to healthy calves, which can later become ill.
At an early stage, the disease is detected only by a blood test. If it was positive at least once, the animal remains infected for life. The virus stays in the body forever, even if the analysis once does not show it.
–You must remember: an infected animal is contagious to other cows! When a dangerous infection is detected, a directive comes into force, describing a strict procedure.
In Russia, new veterinary rules for the control of bovine leukemia came into force on September 1, 2021 and will remain in force until September 1, 2027. They are approved by order of the Ministry of Agriculture of the Russian Federation. According to Irina Donnik, Doctor of Biological Sciences, Professor, Vice President of the Russian Academy of Sciences, the new veterinary rules can be a real breakthrough in the fight against infection.
If an animal with a positive diagnosis is found on a farm of any property, it is considered unfavorable for leukemia. Restrictions are envisaged, a plan is being developed to improve the herd. It is forbidden to keep infected animals together with healthy ones (they must be completely isolated or handed over for slaughter). Do not move animals without the knowledge of the veterinary service.
Many villagers drink milk from cows that are positive for leukemia and give it to their children. The use of such milk without boiling or pasteurization is prohibited. During heat treatment, the virus dies, but the products of its vital activity remain. This can lead to the development of diseases, including cancer. Colostrum from sick and infected cows should not be used to feed calves. Milk and colostrum obtained from sick cows, according to the new veterinary rules, are subject to destruction.
It is necessary to inform the veterinary service in time for all cases of animal disease with suspected leukemia. At the request of specialist veterinarians, owners are required to provide all necessary information on the bovine animals obtained and to provide the conditions for their examination, research and treatment. The implementation of the restrictions imposed on the farm is under the control of veterinarians. Non-compliance will result in fines.
Health measures are expensive, so any dairy farm should pay close attention to preventing leukemia. Today, the only way to protect a healthy bovine population from infection is to eliminate livestock from the herd. By the way, several farms in the Birsk area have already started informing their animals.
In connection with the close attention of the Rosselkhoznadzor administration, the Birsky area has been placed under special control. The results of the work of the Veterinary Service were brought to the attention of the Head of the Republic of Belarus, Radiy Khabirov, of the Ministry of Agriculture of the Russian Federation.
