Even experienced herders can not always answer the question why the calves have wool, at least during a cursory inspection. Perhaps there is nothing to worry about, and the animal has just a seasonal molt, it comes in late autumn and early spring. But sometimes, calves do not have enough vitamins. In other cases, hair loss is a symptom of a serious illness. There can be many reasons for hair loss, and for effective treatment it is necessary to accurately determine them.
Need to be vigilant
A healthy calf is easy to recognize:
- he is mobile;
- has a good appetite;
- the coat is smooth and shiny;
- the calf looks healthy.
The fact that he has a coat falls out is a normal reaction to the change of seasons. There is a change of hair twice a year: in the last month of autumn and the first month of spring.
All animals have their own molting period, and a good owner always remembers the numbers at which it can begin. Such knowledge simplifies working with cows, and breeders do not worry about the fact that animals begin to lose wool, knowing that this is a normal state of the body.
Worrying is, if the wool begins to fall out "outside the schedule of molting." Special vigilance should be shown when you notice not just hairs, but whole tufts of fallen out hair. Another alarming symptom - the formation of bald spots on the skin of the animal. Having noticed such signs, you should immediately contact a veterinarian.
Improper feeding as the cause
The health of cattle affects diet. Proper feeding of cows is very important, especially in the first months after calving, because a large proportion of vitamins goes into the milk that the calves eat. The baby himself should receive an additional dose of vitamins and minerals with food and drink.
Improper feeding, as well as a lack of vitamins in the body, lead to the fact that calves begin to fall wool. The body of the young can not digest roughage, from poor-quality food in animals allergy begins. In both cases, the immunity of calves weakens, as a result of which the wool begins to fall.
Vitamin D is responsible for the growth of hair in the body of an animal. When it is lacking, a disease such as rachitis or vitamin deficiency develops. One of the first symptoms of the disease is hair loss.
Fungi, parasites and hormonal disruptions
Fungus is an extremely common cause of hair loss in animals kept in poor sanitary conditions. It penetrates wounds, cuts and scratches on the skin of calves. Peeling begins in the affected areas, the wounds are covered with a crust. The cause of hair loss in such cases is simple fungi such as trichophyton or microsporia.
Calves' skin is the habitat of many parasites, some of which cause damage to the body of animals. Pear bites and hair eaters often cause hair loss, and they can become infected when in contact with other animals. To avoid this, follow the sanitary conditions in the barns.
Hormonal disruptions can also lead to loss of hair in calves. This happens if you give them hormones or regularly interfere with the phases of mating. This leads to a general weakening of the body of young and hair follicles in particular.
If you do not notice the fungus in time, it develops into a lichen, a serious fungal infection that leads to massive baldness of the animal. In the early stages, the lichen appears as a normal fungus: the skin flakes off and crusts. In acute form, the disease manifests itself in the form of purulent vesicles.
Deprive the animal causes severe discomfort, itching. Calves become restless. You can see the painful areas in cows and bulls on the neck, tail, head and sides. Most often, it affects calves that are under 2 years of age. Pathology is extremely contagious, so sick individuals should be kept separate from the main herd.
The easiest way to prevent the occurrence of lichen, making a timely vaccination of calves. If for some reason the vaccination could not be carried out, and the calf caught a fungal infection, treatment begins with a change in diet and improvement of nutritional mixes. Next, carry out the stall disinfection and proceed to treatment. An effective remedy for depriving is considered the drug "Zoicol".
The danger of demadekoza for animals
Demadekoz (or scabies) often affects cows and calves. Pathogens become parasites that settle on the skin of animals. They penetrate the sebaceous glands and hair follicles, contributing to hair loss in the affected areas. Inflamed areas scaly and do not give the young rest.
In adult cows, scabies is often not accompanied by itching, which may prevent timely conclusions from being drawn. If time does not recognize the disease, the parasites will move to other animals, leading to an epidemic. Pathology is highly contagious and, when diagnosing it, cows infected with scabies are isolated from the herd.
Recognize the disease can be by external signs. On the skin of calves appear bumps with a diameter of about a centimeter. Their surface is always wet, and when pressed, a turbid liquid flows out of the bulges, which contains mites.
Lice are a problem to solve.
Most often, lice infest the wool of cows and the winter months. Animals with thick hair are at particular risk. Lice live off the host, feeding on its blood and breeding on its skin. Egg laying parasites in the root of the coat. An inexperienced farmer might think that the animal just had dandruff.
The danger of lice is often underestimated. In fact, they severely injure the skin of the animal and inject saliva into the cells, which has a toxic composition. The cow begins to worry, irritation appears on the skin, detachment of the upper layer occurs, manifested by the formation of many scaly particles and accompanied by itching.
If you do not start to fight lice in time, dermatitis may develop on the skin, and the affected areas will start to go bald. At this stage, the disease is poorly treatable, as there are too many parasites on the animal’s body.
The main danger of lice is that they easily jump over healthy individuals, settling in the undercoat of the herd as soon as possible.
Alopecia as a symptom of gastric damage
If calves are not properly fed, they may develop coronavirus enteritis. It is precisely by hair loss that it is easy to install, since most gastric infections are not accompanied by alopecia. To confuse it with skin diseases is quite difficult.
The cause of the infection becomes non-compliance with sanitary and hygienic conditions of detention. Enteritis is easily recognized by symptoms:
- greenish yellow diarrhea;
- bloody mucus in feces;
- hair loss.
The disease can be fatal. You should not hesitate and try to decide on your own what to do and how to help the animal - if you suspect any enteritis, you should contact your veterinarian.
