Cows from ancient times were the breadwinners of people, but recently their owners, wanting to get quick profits at minimal cost, do not pay attention to the quality of feed, which as a result harms the body of animals, making them susceptible to various allergens.
Consider what problems may arise in cows.
What is allergy
The body's reaction to various stimuli: dust, certain types of food, medications, accompanied by coughing, sore throat, redness of the eyes, sneezing, nasal pharynx congestion - this is an allergy.
Did you know? The least allergenic animal is chinchilla. This is facilitated by the absence of salivary and sweat glands, as well as the fact that the animal's coat does not contain substances that can be perceived by the immune system as an allergen.
Sources and factors provoking allergic reactions in animals
Various substances can trigger an allergy attack:
- feed additives;
- dust;
- medicinal substances;
- pet care products;
- insect bites.
Food and biological additives
Allergies to food and dietary supplements have recently become the most common among cows, especially young ones.
Causes of an increase in allergies:
- The feed contains a large amount of protein.
- Natural milk is replaced by soy product.
- The feed contains many chemical additives.
Important! Feeding calves with a milk replacer supplemented with soy is a potential allergen.In young animals, the gastrointestinal tract is affected and skin lesions occur, leading to discomfort — the animal constantly itches. And such inflammations can form in different parts of the body.
Medications
An allergic reaction to medicinal substances occurs mainly on repeated administration of the same drug.
These include:
- antibiotics;
- novocaine;
- certain types of vaccines;
- hormones;
- certain anti-inflammatory substances;
- vitamins.

Environmental elements
Sometimes animals may become allergic to grass, flowering or pollen. Symptoms appear at the age of about 6 months. It is proved that the disease can be inherited. In this case, the minimum amount of allergen is enough for the immune system to fail. Treat the animal in such a situation will need to be systematically, as it is impossible to completely eliminate contact with the environment. 
Insect or animal bites
The most common type of allergy in animals is flea saliva. To identify this is quite difficult, since these insects breed their offspring outside the skin of the animal. To start the development of a negative reaction of the body, one bite is enough.
After that, saliva enters the bloodstream, and the immune system almost immediately gives the appropriate response.
Similar problems may also occur as a result of a wasp or bee sting.
Did you know? Despite the huge number of sources of allergy, after the bites of animals, it can not appear. In this situation, you may experience only other problems with the body.
Allergy symptoms
When food allergies are observed:
- stomach cramps and pain, nausea and vomiting;
- violation of the digestive tract, which, in turn, causes constipation or diarrhea;
- tongue covered by a touch;
- inflammation of various areas of the skin with swelling and rash;
- the blood test shows a sharp increase in lymphocytes and immunoglobulins.
Cow diarrheaWhen the dosage form of allergies can occur:
- fever;
- joint pains;
- disorders of the heart;
- various skin rashes;
- swollen lymph nodes, especially close to the point of injection;
- anaphylactic shock.

What to do, how to help the animal
At the first signs of illness, the animal must be given first aid. It is to exclude contact with the allergen, as well as the obligatory treatment to a specialist to obtain the necessary medical care.
First aid
The owners of animals in the first-aid kit should always be anti-allergy drugs ("Dimedrol", "Tavegil", "Suprastin"), the use of which will ease or relieve the symptoms of the disease. You must also find out the cause of allergies and eliminate it. To confirm the diagnosis you need to contact a veterinarian.
Important! Drugs should be used exactly according to the instructions, and their dose should be calculated based on the weight of the animal.
Further therapy
The doctor, on the basis of the owner's story about the diet and the use of drugs, as well as after examining the barn and getting acquainted with its sanitary treatment, determines the most likely allergen and prescribes treatment:
- Antiallergenic drugs intramuscularly: Prednisolone, Hydrocortisone, and intravenously: 10% solution of calcium chloride. In severe cases, it is possible to use vascular agents - adrenaline and noradrenaline.
- To raise and maintain immunity, vitamin complexes containing ascorbic acid, retinol, vitamins E and group B.
- In order to avoid dysbacteriosis, animals are given antimicrobial drugs, such as Polypefan, Etazol, Enterol, and others.
- To restore the intestinal microflora is obligatory reception "Lactobacterin" and "Bifidumbakterina".
The main factor affecting the development of allergy in cattle remains the feeding regime. Feed must be of high quality, and the choice of additional additives must be approached carefully and carefully.
