Emphysematous carbuncle, or emcar, is a dangerous bacterial disease that affects ruminants - cows and sheep. The disease causes irreparable harm to agriculture and is easily transmitted from one individual to another. Therefore, prevention of emkar is of great importance for the well-being of the economy and high profits. It is important to strictly follow the instructions for using the emkar vaccine to create lasting immunity.
Composition and release form of the drug
The vaccine is sold in the form of a gray suspension, sealed in a glass bottle of 50, 100 and 200 cubic meters. see. The supernatant may be gray or yellow, depending on the manufacturer or shelf life.
Aluminum hydroxide is used as an additional substance - 35% of the total volume of the vaccine. The main active ingredient is a strain of microbial anaerobic cells Clostridium chauvoei R15 - emkar pathogen in a weakened form.
Indications for use
Used for the prevention of emkar disease in cattle and sheep. As a result of the use of the vaccine, stable immunity is formed that lasts for 6 months. The vaccine does not harm the animal’s immunity and allows the cells to independently begin to produce the necessary antigens. After applying the vaccine, cattle and sheep do not lose productivity and continue to produce milk, meat and wool in the required quantities. The immune response is formed in 14 days, the body is fully restored during the same period. The vaccine cannot be used to treat emphysematous carbuncle.
For additional prevention, pastures are drained, especially swamps and floodplains near the suspected site of animal infection. It is unacceptable to overfill manure pits or keep young animals too crowded. There should not be cattle burial grounds within 5 km from the farm, especially in areas unfavorable for emphysematous carbuncle.
Instructions for use of the Emkar vaccine for cattle
Vaccination of cows can only be carried out by people with higher or secondary veterinary education.Before you start administering the drug, you must change into special clothing that protects your hands and face. The use of rubber aprons and boots is mandatory. If a small amount of the substance gets on the mucous membrane, you need to thoroughly rinse the area and treat it with a disinfectant solution.
If any response occurs - redness, itching, tearing - you must immediately contact a medical facility.
Emphysematous carbuncle is considered a particularly dangerous disease, therefore each vaccine is subject to strict registration during livestock vaccination. Vaccination of cattle is carried out starting from 6 months. There may be a different schedule of injections - before pasture and after the end of the grazing season.
Injections are renewed every six months, with the exception of calving cows and pregnant sheep. In farms that are unfavorable for emkar, all livestock are vaccinated unscheduled for preventive purposes. Before use, the bottles are heated in the hand or in a warm water bath to a temperature of 35-36 degrees. Vaccination is carried out intramuscularly, in the upper third of the cow's thigh, in compliance with the rules of asepsis - the injection site is treated with 70% alcohol, disposable, sterilized instruments are used for animals.
Treatment can begin no earlier than 20 days before the cows are released to pasture. Animals over 4 years old are not vaccinated due to economic inexpediency, however, if an epidemic occurs, they are also treated.
Undesirable effects
The vaccine is safe to use and in most cases does not cause side effects. In sensitive or sick animals it can cause general depression, refusal of food and decreased productivity.Sometimes a local increase in temperature is observed. In case of persistent depression, you should immediately contact a veterinarian. It is not recommended to use the vaccine simultaneously with other immunological drugs, so as not to cause too strong a response from the body.
Cases in which the vaccine is prohibited
It is prohibited to use the vaccine for pregnant animals, especially in the last month of pregnancy or pregnancy. Not recommended for use on steers or rams after castration or any other surgical interventions. After calving, you need to give the body time to recover, at least 7-10 days.
The vaccine is prohibited for use as a therapeutic drug, but is used only for prevention. After forced slaughter, meat can be used without restrictions - the drug does not pose a danger to humans. Meat or milk of already sick animals is prohibited from being consumed - it must be disposed of mechanically or chemically. The corpses of sick animals are burned.
