Trichophytosis or lichen vulgaris is a fairly common fungal infection of the skin. It gives the animal a very unpleasant and painful sensation and quickly spreads throughout the body. It can move to a person, so how is the lichen manifested in calves and we will consider treatment now.
Reasons for which can occur
The main reason for this unpleasant ailment can occur - it is contact with sick animals, as well as non-observance of sanitary and hygienic conditions. The fungus also gets through wounds, minor abrasions, scratches. To notice whether a cow or calf is easy.
At the site of the lesion, peeling, formation of crusts, and then hair fall out, which is clearly seen in the photo provided at the end of the article. The causative agent of the disease, the fungus Trichophyton very quickly develops in the cells of the epidermis and blocks the hair follicles. In case of contact with the skin, the first symptoms may develop in 5-7 days.
It is important to note that, in addition to external problems, have deprive a bad effect on the health of animals. Thus, in young cattle and calves, it inhibits growth and development. In adult cows it often causes exhaustion and decreased productivity.
Forms of the disease
Trichophytosis has a rather long incubation period - on average from 10 to 30 days. The main symptom of the disease is the occurrence of dense tubercles with the subsequent death of skin cells and hair loss. In calves, most often the disease affects the head, the area near the eyes, mouth, on the forehead, near the ears is vulnerable. In adult cows, it is found all over the body, especially on the neck, chest and back, as seen in the photo. Today, there are several forms of depriving:
- follicular or deep;
- vesicular or vesicular.
As a rule, in adult cows, the most often superficial and erased form of the disease is observed, in calves - follicular. The latter vesicular form affects the crotch area, labia, inner thighs.
The complexity of the treatment of this disease lies in the fact that the spores of the fungus are very resistant to external factors. On fallen crusts of skin and on hair follicles, they can live up to 1.5 years. When boiling, they die after 3 minutes, with a 100-degree heat treatment - after 20 minutes, the ultraviolet rays destroy spores within 30 minutes. Disinfectants, in particular, formaldehyde, carbolic acid, salicylic acid destroy the fungus within 15-30 minutes.
Disease treatment methods
The method of treatment is prescribed by a veterinarian, depending on the degree and form of the disease. Among the preventive measures used vaccination. But it can also be assigned already at the obvious stage of the disease. This helps to destroy the already spreading fungus and form a local immunity.

It is important to remember that depriving treatment can not be delayed, this disease spreads very quickly and can completely undermine the entire immune system of the cow. It is also necessary that both sick adults and young animals be provided with good nutrition. They are placed in a separate pen, and even better in a separate room.
