How to treat smallpox in cattle
A cow is an important animal in the farm. Being a sacred animal in some cultures, cows are actively used in others mainly for milk and meat. In this regard, the breeder must know not only how to take care of the cow on the farm, but also how to behave if the animal becomes ill. One of the most common and dangerous diseases is cow pox.
What is this disease
Cowpox is an infectious disease characterized by weakening of the animal, a significant increase in body temperature and the occurrence of ulcers and growths on the udder.
- contact (when a milkmaid touches an animal through a peeling epithelium);
- airborne (through discharge from the oral and nasal areas);
- transmissible (bites of rodents and insects);
- alimentary (through feces).
Important! In addition to the udder, ulcers and growths can also cover the hips, back, head and neck.
The lack of vitamins in the body can also be a factor contributing to infection and the development of the disease, especially in the winter. The disease is characterized by extreme contagion - one sick animal can infect the entire livestock. Infection can also occur after the interaction of cows with food, water or instruments infected with smallpox spores.
Causes of cattle
There can be several reasons for the occurrence of smallpox, and all of them are directly related to the conditions of the cows:
- lack of vitamins due to poor quality and / or malnutrition;
- poorly ventilated barn;
- lack of regular airing;
- dirt in the stall, hay not changing for a long time;
- high humidity in the stall;
- non-compliance with the temperature regime.
Important! One way to reduce the chance of infection during the vaccination period is to follow personal hygiene rules.
Symptoms and course of the disease
Smallpox develops quickly enough, and the following symptoms are inherent in it:
- a significant increase in animal body temperature (up to 40–41 degrees Celsius);
- general weakness, loss of appetite;
- decrease in milk yield;
- unwillingness of a cow to allow a person to milk;
- the appearance on the udder of papules, which over time grow into abscesses and cracks;
- "Wide stance" - the animal is trying to maximize the hind limbs.
The animal is weakening more and more, refusing to eat and milking, trying to position its hind legs as widely as possible. An increase in temperature causes fever. Possible complications in the form of tremor and damage to the respiratory system.
Did you know? A person can also get smallpox from cows, but after the first case of infection, the body develops immunity.
Visual inspection plays an important role in the diagnosis of this disease. However, some external manifestations of the disease, in particular a rash, may be a symptom of other ailments.
Important! If the disease manifests itself in a recently acquired animal, it is necessary to obtain information from the seller regarding cases of smallpox at the previous location of the cow.
The main pathological change during the disease is the appearance of a rash that gradually forms large brown spots on the udder. As the disease develops, the spots dry out, and a crust forms in their place, which can crack, thereby giving the cow additional discomfort and pain.
How and how to treat
Once a cow has been diagnosed with smallpox, you can begin to treat it.
The treatment itself should be carried out under the supervision of a veterinarian, since the doctor will be able to choose the most suitable medications, as well as monitor the treatment process and adjust it if necessary. Nevertheless, it is worthwhile to carry out a number of activities that will contribute to the treatment:
- isolation of a sick animal so that it does not infect the rest of the livestock;
- disinfection in the barn and its regular ventilation;
- transfer to feeding liquid mixtures and the exclusion of low-quality food;
- maintaining dryness to avoid suppuration;
- daily milking of the cow to prevent the formation of mastitis (special catheters are recommended).
The basis for the treatment of smallpox is medication, both external and intravenous (mainly antibiotics). These include:
- antiviral ointments 2-3 times a day - Florenal (0.5%), Oxolinic (3%), Ectaridine lactate (3%), Tebrofenova (5%) for fourteen days;
- 2 times a day - Metisazon (0.6 g) five to six days;
- 2 times a day - anti-venom immunoglobulin (0.3-0.6 g) for five to six days.
Important! When choosing medications, be sure to consult a doctor.
Can I drink milk from sick animals
Opinions regarding whether milk from cows with smallpox can be eaten differ. Some farmers believe that milk can be disinfected by boiling or pasteurization and then suitable for drinking, while others argue that milk from sick animals should be disposed of. The second option is preferable, since any potential harm to health should be excluded.
Smallpox vaccinations for cows come in two forms - separately for each strain. However, the effect of vaccinations varies: vaccination against a smallpox strain is carried out once and provides lifelong immunity, while vaccination against a mixed smallpox strain gives immunity for only a few months, after which repeated vaccination is necessary.
Did you know? Smallpox vaccine was invented by chance. In 1796, a young doctor Edward Jenner, while on a farm, noticed that milkmaids who were in contact with smallpox cows developed a milkmaid immunity to the disease. The doctor conducted an experiment by introducing a strain of virus from a sick animal to a person, and thus opened the vaccine.
Other preventive measures
In addition to vaccinating livestock, disease prevention can be carried out in other ways:
- monitoring of nearby agriculture for smallpox;
- control the cleanliness of food, water and equipment;
- keeping newly acquired animals separately from the rest of the herd for the first month and a half;
- treatment of the udder with antiseptics;
- compliance with personal hygiene;
- regular vaccination of personnel against smallpox, after which the vaccinated are not allowed to livestock for fourteen days;
- isolation of a sick animal from the rest of the herd to prevent further spread of infection;
- utilization of milk received from sick cows.
