The packaging of many feeds is decorated with the inscription: “contains biotin”. This is vitamin H. Feed enrichment with this substance has gained popularity relatively recently. Let’s see: what is the role of vitamin H in the animal’s body? Biotin is defined as a microvitamin, which means that its normal content in the body is very small.
The main properties of biotin
Other names: vitamin H or coenzyme R, refers to the group B vitamins. Soluble in water, non-toxic, unit of measure – µg. Biotin can produce intestinal bacteria, and a raw egg protein significantly reduces its digestibility. It is combined with niacin, vitamins I2 and B6, vitamin A. Beneficial effect on the health of the skin, prevents the manifestations of eczema and dermatitis. Lack of biotin in the body leads to impaired metabolism of fats.
Products containing biotin: brewer’s yeast, unpolished rice, kidneys, nuts, milk, fruits, beef liver, yolk eggs. Vitamin H is incompatible with avidin (found in egg white), estrogens, sulfonamides.
Vitamin H Functions
The main purpose is to participate in the extraction of energy from amino acids and carbohydrates, as well as in the metabolism of fatty acids. Biotin prevents hair loss, maintains healthy skin and strength of the dog’s tendon-ligament apparatus, fights muscle pain and graying, strengthens the structure of connective tissue, helps tendons to heal and regenerate faster.
The path of biotin in the body cells
On the one hand, biotin enters the body with food rich in this substance. After separation of food from proteins, vitamin H enters the blood. On the other hand, the body can independently produce biotin. It occurs in the intestine, under the action of the enzyme biotonidase. The same enzyme most likely serves as a “transport” that delivers biotin into the blood and body cells.
Biotin in action
The biotin molecule is designed to deliver sulfur to the body’s cells. Such a narrow specialization is not characteristic of other vitamins involved in somatic processes. Biotin is involved in providing nerve cells with energy, but it does not affect the processes of the psyche, affecting only the physiological side of the processes.
Biotin – participant in the process of assimilation and synthesis of glycogen stored in the muscles and liver carbohydrates. Also, vitamin H plays an important role in gluconeogenesis. As a result of this process, 16 amino acids from 22 are converted into glucose. The purpose of the process is to maintain a stable blood sugar level.
In addition, biotin acts as an ally of vitamins of group B in the process of metabolism, promotes the absorption of protein. Two other important functions of biotin are fat burning and the decomposition of fatty acids.
“Beauty Vitamin” is the name for biotin, because it contains sulfur that is beneficial for the health of the claws, skin and coat of a dog. More precisely, biotin is an excellent “transport” for sulfur; with it, it gets exactly where the need is strong.
Biotin is involved in the production of hemoglobin, the most important component of red blood cells, and also binds purines and carbon dioxide. Purines contain hereditary information. For the first time, vitamin H was “extracted” from the yolk of the egg. If the dog’s food is balanced, then the biotin shortage is unlikely to threaten it. But the animal, which for a long time receives raw egg whites from food, is such a risk. Proteins contain the substance Avidin, and it prevents the absorption of biotin. If there is a shortage of magnesium in the diet, there is also a risk of developing a biotin deficiency.
What is dangerous biotin deficiency?
If the dog does not receive vitamin H, it can develop depression, anemia, drowsiness, loss of appetite, fatigue, weakness, muscle pain. The animal will increase the content of sugar and cholesterol in the blood. Of the most noticeable external manifestations, the most likely are dermatitis, the appearance of bald patches, dryness and grayish skin.
In addition to balancing the diet, a healthy microflora that inhabits the intestines is very important in providing the body with biotin. Then the body’s own production of biotin will be sufficient. If the dog’s body is unable to synthesize the right amount of biotin (the result of taking sulfonamides, antibiotics, malnutrition), then vitamin H must be contained in sufficient amount in the food that the animal receives.
