Hypovitaminoses of group B


Hypovitaminosis (Hypovitaminosis) called the lack of certain vitamins in the diet of the animal. There are also pathologies when one vitamin is not enough, and the other, as a result, is not absorbed and causes a whole complex of functional disorders.

The disease affects all species of domestic and wild animals on all continents of the planet.

The main cause of the disease is the imbalance in animal feeding. A pathology of this nature can be observed temporarily (in winter, during the stall period) or in a certain physiological state (pregnancy), or constantly if the rules for making diets are not observed.

The cause may also be endogenous factors. With violations of the organs of the gastrointestinal tract or endocrine system.

Hypovitaminosis is also possible with prolonged use of drugs, of any group that blocks absorption or completely destroys one or another vitamin.

Often, hypovitaminosis is mixed in combination with a combination of endogenous and exogenous factors.

The need for vitamins for each type of animal is different. Carnivores, herbivores, and omnivores, as well as birds, need different types and amounts of vitamins. The need is also affected by age, physiological condition, gender, performance.

Hypovitaminosis causes livestock farming significant economic damage. Even if the pathology manifests itself in a sluggish current form, the lost weight gain of the livestock, milk production, hair cutting, the loss of egg production, abortion and barley significantly affect profitability.

The most well-studied hypovitaminosis A, D, E, K, B1, B6, B12, C, PP. These pathologies have an erased clinical picture and are chronic. Vitamins are part of the prosthetic groups of enzymes, and deficiency leads to disruption of the activity of enzymatic systems.

All hypovitaminoses are manifested by a different clinical picture.

In case of vitamin A deficiency (retinol), all animals will show dullness of the coat, peeling of the skin, weakening of vision, conjunctivitis, decreased sexual activity, barrenness, infertility, growth retardation, a predisposition to diseases of the gastrointestinal tract and nervous system.

Deficiency of vitamin D (caceferol) causes osteodystrophy and rickets.

E-hypovitaminosis, tocopherol deficiency, will lead to impaired reproductive functions of both males and females, causes elementary muscular dystrophy.

Phylloquinone deficiency, vitamin K, will manifest as hemorrhage and bleeding disorders. Particularly sick are those animals in which this vitamin is not synthesized in the gastrointestinal tract - these are birds and fur animals.

Hypovitaminosis C (ascorbic acid deficiency) is manifested by a violation of the functions of the blood-forming organs, the formation of ulcers on the gums, swelling of the joints, and in the red-footed furry. If many animals can synthesize vitamin C from carbohydrates in the liver, then primates and guinea pigs cannot do this and are very sensitive to failure.

Group B hypovitaminoses are more common in single-chamber animals (pigs, dogs, fur animals). Ruminants can satisfy the need through microbiological synthesis in the pancreas. In horses (unlike other single-chamber) synthesis takes place in the large intestine in the colon and cecum.

With deficiency of vitamins of this group, growth retardation, the birth of weak young animals, dermatitis and impaired functioning of the cardiovascular and nervous systems are noted.

Deficiency of vitamin PP (nicotinic acid) is manifested more often in piglets, dogs, birds, less often in other animals. A distinctive feature of pathology is peeling of the skin, stomatitis, swelling of the tongue and fissures, and disturbances in the functioning of the gastrointestinal tract.

Diagnosis is based on an analysis of the diet of the corresponding age group of animals, taking into account productivity. When evaluating clinical signs, it must be borne in mind that hypovitaminosis can occur with insufficiency of micro and macro elements.

Hypovitaminosis should be differentiated by making a thorough analysis of the epizootological situation.

For research, blood, milk, colostrum, and eggs are sent to the laboratory. Determination of Vit A content, calcium, inorganic phosphorus, alkaline phosphatase activity, will help diagnose pathology.

Using vitamin preparations with the suspicion of one or another hypovitaminosis, it is possible to very quickly achieve a therapeutic effect.

If the diagnosis is correct, then a few injections relieve the clinical signs.

For therapeutic purposes, retinol acetate, tocofecol concentrate, Vikasol, ascorbic acid, thiamine bromide, workflavine, nicotinic acid, pyridoxine, cyancobalamin, triivitis, tetravit, oil concentrates of vitamins, fortified fish oil are used.

Vitamin deficiency and hypovitaminosis

Lack of vitamins is a fairly common occurrence. It is worth noting that vitamin deficiency and hypovitaminosis are different concepts. The first has gained popularity, but it is characterized by the complete absence of a vitamin or a group of vitamins in the body. The second concept describes a less serious condition and means a lack of vitamins. At risk are pregnant women and children, that is, those whose developing body systems require additional intake of vital amino acids. Although due to adverse environmental conditions and poor-quality food, hypovitaminosis, especially in the autumn-winter period, is found in almost every person. Depending on the specific group of missing substances, this condition can manifest itself with various symptoms. But all of them are united:

  • fatigue, weakness and drowsiness,
  • change in mucous membranes or skin,
  • irritability.


Preventive measures are aimed at balancing the diet of animals according to: type, age, productivity.

When feeding animals with compound feeds, careful laboratory monitoring of the vitamin and mineral composition, as well as the measurement of the content of nitrates and nitrites in the feed ration, is necessary.

To prevent Vit D deficiency, animals are walked with sunbathing or under artificial UV exposure.

When drawing up diets do not allow the same feeding of animals. When feeding industrial waste (beet pulp, mash, pellet, etc.), the diet must be balanced by the addition of vitamin preparations.

Prevention is based on the prevention of diseases of the gastrointestinal tract, as well as the reasonable use of drugs that interfere with the digestibility of certain vitamins.

The use of benign feed is the basis for the prevention of hypovitaminosis.
