Detailed explanation of the role of vitamin elements in dogs

Vitamin A:

Vitamin A is a fat-soluble vitamin and a fat-soluble long-chain alcohol. It is abundant in liver, fish and eggs.
Plant feed does not contain vitamin A, but the beta carotene it contains can be converted into vitamin A in the dog's body.

Function of vitamin A:

Vitamin A is absorbed by the small intestine and stored in the liver.

Visual vision

The main physiological function of vitamin A is to maintain normal vision and the normal physiological functions of mucosal epithelial cells. It is a component of retinal pigment required for visual cells. Especially essential in maintaining normal dark adaptation.

Skin and coat

Regulates the growth of epidermal cells and the production of sebum, inhibiting dandruff and eliminating seborrhoea.

Pregnancy period

Essential for normal fetal growth.

Symptoms of vitamin A deficiency:

When dogs are deficient in vitamin A, they will first show reduced dark adaptation ability and even suffer from night blindness and dry eye disease. The sick dog's cornea will become thickened, keratinized, and cloudy, and sometimes ulcers and perforations will appear. , or even blindness; stunted growth and weight loss.
When vitamin A is lacking, the reproductive capacity of male dogs decreases; female dogs may suffer from infertility, miscarriage, stillbirth, weak fetuses, and give birth to blind puppies; puppies may suffer from weakened disease resistance, diarrhea, and may develop optic atrophy. This can lead to blindness and often death from pneumonia.

Symptoms of excessive vitamin A:

Dogs have a high tolerance to large amounts of vitamin A, but high doses of vitamin A may cause joint abnormalities or reduced reproductive function. Adding too much vitamin A can cause poisoning in dogs, which can cause nerve sensitivity, tremors, petechiae bleeding on the abdomen and legs, blood in the feces and other symptoms, which can eventually lead to death. Excessive vitamin A can also cause miscarriage in female dogs, lethargy in puppies, and reduced food intake.

How to supplement vitamin A:

Carrots, yellow corn, milk, eggs, meat, liver and other foods are rich in vitamin A or beta carotene. Dogs can be fed the above-mentioned foods regularly during the feeding process. If necessary, an appropriate amount of cod liver oil can be added to the food to supplement vitamin A.

Vitamin B1:

Vitamin B1 is also called thiamine. Its main physiological function is to participate in carbohydrate metabolism. It is an essential nutrient to maintain normal nervous system function.
It is most abundant in yeast and wheat germ, and also in meat, bran, rice bran and grains.

The role of vitamin B1:

Participates in most complex biochemical reactions and is necessary to generate the energy required for cell activities. Participates in the synthesis of the neurotransmitter acetylcholine (neurotransmitter) and has the function of assisting in the transmission of intuitive stimulation.

Symptoms of vitamin B1 deficiency:

When dogs are deficient in vitamin B1, puppies will show swelling of the forelimbs and pulse Acceleration, heart dilation, and death due to heart failure within a few days; elderly dogs show ataxia, chicken lameness, hindquarters, limbs, and vocal cord paralysis in the later stages, and sometimes convulsions and falling to the ground with opisthotonus.

How to supplement vitamin B1:

You can add yeast, rice soup, milk, lean meat, etc. to food.

Vitamin B2:

Vitamin B2 is also called riboflavin. Its main physiological function is to participate in the metabolism of nutrients in dogs as a coenzyme. One of the indispensable cofactors for the volatilization of specific enzymes. It is widely distributed in nature and is abundant in yeast, liver and eggs.

The role of vitamin B2:

It has the effect of maintaining skin health and improving coat quality. Participates in a variety of biochemical reactions, such as the production of energy from fat, the dissimilation of amino acids, and the activities of energy factories in cells.

Symptoms of vitamin B2 deficiency:

Vitamin B2 deficiency in dogs manifests as slow growth, loss of appetite, rough coat, diarrhea, anemia, and secretion from the corners of the eyes. Increased food intake, xeroderma limited to the skin around the eyes and abdomen, photosensitivity, decreased reproductive and lactation performance, and some dogs develop stomatitis and scrotal inflammation.

How to supplement vitamin B2:

Add yeast, meat, milk, etc. rich in vitamin B2 to food; you can also take riboflavin 15 to 20 orally mg.

Vitamin B3 (niacin):

Vitamin B3 is also called niacin. Its main function is to participate in the metabolism of lipids, carbohydrates, and proteins. It can be synthesized from the essential amino acid tryptophan in the dog body, but these amounts cannot meet the daily needs.

The role of vitamin B3:

Works with other B vitamins (pantothenic acid, choline, inositol) and amino acids (histidine) to synthesize ceramide to avoid dry skin. It is an effective nutrient for preventing pellagra in humans.

Symptoms of vitamin B3 deficiency:

Foods with fewer animal nutrients can cause deficiency. Dermatitis develops on the abdomen and hind legs.

How to supplement vitamin B3:

You can eat these vitamin B3 contents in liver, yeast, egg yolk, and beans Higher food.
