Treating cones on the body of a cow

For the full breeding of cattle, it is required to understand the specifics of many diseases. Sometimes it happens that cones appear on the body of a cow, in connection with which farmers are very interested in the question of where they came from. The most common disease is nodular dermatitis, or tubercle. Such an ailment leads to the fact that even bumps appear on the animal’s head and it becomes completely covered with tubercles.

Cones on the body of a cow

If bumps appear on the body of a cow or on the head, measures must be taken immediately. They can occur on completely unpredictable parts of the body: on the udder, navel, neck, stomach, back, etc. Any rashes on the skin of the animal indicate the development of the disease, and so that the disease does not become chronic, you need to start treatment as soon as possible. Some farmers make smallpox vaccines, but they do not always prevent such a disease.

You can see in more detail what tuberculosis looks like in a photo or video.

Symptoms of Nodular Dermatitis

  • temperature is about 40 ° C;
  • lethargy and passivity;
  • discharge in the eye area;
  • poor appetite or refusal to eat;
  • profuse salivation;
  • the appearance of tubercles throughout the body;
  • reduction in milk yield.

What is nodular dermatitis or tubercle

The virus of nodular dermatitis is transmitted by blood-sucking insects. Such diseases were previously considered exotic and spread not so long ago. Tuberculosis until the middle of the twentieth century spread mainly in Africa, but in 1963 it was registered in Europe. Until recently, Russia did not know about such an insidious disease, but every year there are more and more cases of nodular dermatitis.

Nodular dermatitis is a dangerous virus, which is obtained due to several DNA viruses that are similar in structure to goatpox.

Many farmers vaccinate against smallpox in order to try to protect the animal. The causative agents of the virus are so active and stable that they easily tolerate three levels of freezing and the same number of thawing periods. The fight against such a virus is complicated due to the fact that even if the premises are treated with disinfectants, the virus cannot be eliminated.

A lump on a cow’s body can appear anywhere. The tubercles can be both throughout the body and in some separate area. Both an adult and a calf can become infected.

How to detect nodular dermatitis

The incubation period can last from 3 to 13 days. Basically, the disease can occur in the middle of the incubation period. When milking, most often you can take a closer look at the animal and first of all notice dry tubercles on the leg, udder, nipple, stomach, side. A lump in a cow can also be under the skin. Also, most of the tubercles can be purulent. If you notice at least a few seals or rashes, you need to immediately examine the cow completely. It is very important to examine the oral cavity and pharynx. There are cases when there are rashes on the cheek, inside and under the jaw, in the throat.

The tubercles can be small, but after a while, larger ones will appear next to them. This will continue until many cones form a whole canvas, instead of the skin there is a kind of hard surface. The disease instantly progresses, and within a couple of hours after the formation of the first bump, you can notice how the whole cow became covered with tubercle. In the center of each tubercle you can see a hollow on which after a few days you can remove the cork with a diameter of at least one centimeter. If the subcutaneous bumps hit the udder of the cows, then the milk may turn pink. A person cannot become infected with such a disease, but it incurs losses for farmers, as milk yield is reduced.

Disease treatment

As soon as the first signs of tuberculosis become noticeable, you need to invite a veterinarian to develop further treatment. After taking the tests and visual examination, the specialist must confirm or refute the diagnosis, and then prescribe treatment. Animals that have been diagnosed with the disease, during milking, are separated from the general herd and placed in quarantine. If purulent wounds are on the udder, then such milk is no longer subject to consumption, since it may contain purulent discharge. It is very important during the milking all the time to examine animals for the presence of diseases.

The appearance of at least one tubercle is a clear sign of the manifestation of a disease. If the disease was confirmed on the basis of analyzes, then the treatment is most often prescribed with Biferon-B, Gentabiferon-B drugs. On average, the disease lasts about a month. The number of injections is calculated only by the veterinarian taking into account the phase of the disease, the condition of the cow and other factors. Self-treatment at home is completely excluded. Basically, one injection is enough as a prophylaxis. In advanced cases, 3-4 injections may sometimes be needed. The quality of injections should be very good, since the introduction of a poor-quality drug will not produce results.

Such preparations can only be used with pregnant cows. If the female is pregnant and the term is already suitable for childbirth, then the injection acts only on the burenka, and the calf will not receive treatment. In this case, the female can transmit the disease to the calf, so experienced farmers believe that it is possible to give the calf an injection on the first day after birth. It is possible to find out if a calf has tuberculosis by the fact that immediately after birth, the cub begins to vilify without visible signs. At the same time, the skin of a newborn calf most often does not have any rashes.

Disease prevention

Ill cows can be infected with tubercle from the producer bull through his sperm for about 2 months, so it is very important to inspect your herd, identify the disease on time and keep the cows and bulls in different pens. When breeding cows for sale in the area where the outbreak occurred, it is not allowed to sell such animals for another year outside the region.

With proper treatment and compliance with the rules for the care and maintenance of cattle, animals recover in 90% of cases. It takes farmers time and costs to identify and treat such a disease, milk yield is significantly reduced, this undermines the economic side of cow breeding.

Milk obtained on a farm where there are diseased cows is not to be used. Since when a disease occurs, cows and bulls begin to lose weight and refuse to eat, the meat orientation also suffers. As a prophylaxis, in order not to incur losses, it is recommended to use a vaccine. Today it is the only and effective preventive measure against tuberculosis. A heterogeneous vaccine can create immunity in cattle for 2 years. If you use the lyophilized culture vaccine Neethling, then the result is saved up to 3 years.

Useful tips and tricks

If you want to vaccinate your herd, you need to know that after the first vaccine is re-put the same after 45 days. The dosage is increased by 5 times, based on how much was put for the first time.

In our country, such a disease is relatively new, so not all veterinarians can visually make an accurate diagnosis the first time. In order to accurately determine nodular dermatitis, you need to take tests. To be sure that the animals are kept in proper conditions, a general cleaning of the barn should be carried out weekly with the use of disinfectants.

If a new individual is acquired in a herd, then first it must be quarantined, and only then, after a month, if no illnesses have manifested, can it be transferred to the main herd. Keep animals in quarantine in a separate room.

It is not necessary to perform many actions, over-protect the livestock, all prevention can be based on ensuring that animals live properly in comfortable conditions. The barn should always have fresh air in the summer, and in the winter you need to get a good ventilation system. If this is not done, then in the stale air various viruses, bacteria and insects are formed that can carry diseases. Than to cure an ailment, it is much more profitable to prevent it. Close to cells (either near cells, or near cells, or close to cells).
