Vitamin Vitamin discovery is one of the great discoveries of the 20th century. However, its discovery is related to athletes. In 1897, C. Ekman found that only the fine -grinding white rice was found in Java. It was also found that the substances that cure footage can be extracted with water or alcohol. At that time, the substance was called "water -soluble B".
1906 proved that food contains "auxiliary factors" except protein, lipids, carbohydrates, inorganic salts and water, which is small, but it is necessary for animal growth. In 1911, Fengke identified the substance that could fight with qi in brown rice was amine (a type of nitrogen -containing compound). It was necessary to maintain life. Therefore, it is recommended to name it "Vitamine". That is, vital (life) amine (amine), which means "life amine" in Chinese.
In the future, many vitamins have been discovered one after another. They have different chemical properties and different physiological functions. It is also found that many vitamins do not contain amine and do not contain nitrogen. The initially discovered vitamin B was later confirmed as a vitamin B complex. After purifying separation, it was discovered by several substances, but the nature was similar to the distribution in food, and most of them were coenzymes. Some supply must be balanced with each other, such as vitamin B1, B2, and PP, otherwise it can affect the physiological effect. The discovery and application of vitamins not only brings huge changes to the human world, but also the nutrients necessary for pets.
Vitamin, no one can be less
Vitamin is a necessary metabolism for pet constitutions and is a low -molecular organic compound with a small amount. It is generally unable to synthesize in the body. It mainly depends on pet food provision. In addition to several types of vitamins, most of them require pet foods. Added additional adding in manufacturing.
Vitamin is not a tissue and organ raw material for the formation of the body, nor is it energy substance. It is mainly involved in the body's metabolism in the form of coenzymes and catalysts, thereby ensuring the cell structure and normal function of the body tissue organs, maintaining pet health and various production activities. In pet foods according to specific factors such as pet varieties, different physiological stages, and development status, it is required to be added very strictly. It cannot be replaced with vitamins required by other animals. Do not add sensitive changes.
Some vitamins can be synthesized by the pet's own body, which do not need to be added during pet food manufacturing and production. In this way, the cost of pet food is increased without practical significance, but some vitamins must be added to pet food, because pets themselves cannot be synthesized and difficult to obtain from other channels, only from food.
Different types of vitamins have different physiological effects and characteristics on pets, and lack of or excessive impact on pets. Therefore, this requires strictly grasping pets' demand for different vitamins in the preparation of pet food.
Vitamin, how to control it moderately
There are 14 types of vitamins that have been determined at present. According to their solubility, they are divided into two categories: water -soluble and fat -soluble. Different vitamins have strict requirements on their dosage. Properly adding a positive role in the healthy growth and development of pets, improving product palatability, improving physical immunity, and prevention of diseases. Lack or excess will bring serious adverse consequences to the body of the pet.
Once vitamin intake is lacking or eaten, it will bring pets such as poisoning, organ degeneration, hair removal, difficulty in action, unable to stand, hemolysis, loss of appetite, myocarditis, muscle atrophy, stagnation of growth, blindness, anemia, spasm, hypoxia, hypoxia Even serious consequences such as death, so it must be added in strict accordance with pets in pet food.
Vitamin, where are you?
The extensive food contains rich vitamin nutrients, specifically:
Vitamin A: Animal liver, eggs, dairy products, carrots, pumpkins, bananas, oranges and some green leafy vegetables;
Vitamin B1: Sunflower seeds, peanuts, soybeans, pork, cereals;
Vitamin B6: Meat, cereals, vegetables and nuts;
Vitamin B12: Pig, beef and mutton, fish, poultry, shells, eggs.
Vitamin C: lemon, orange, apple, jujube, strawberry, pepper, potatoes, spinach;
Vitamin D: cod liver oil, eggs, artificial butter, milk, tuna;
Vitamin E: grain embryo, vegetable oil, green leaves;
Vitamin K: Green leafy vegetables.
Only by fully understanding different vitamin categories contained in different foods can we help us effectively control the addition and supplement of vitamins in the process of pet feeding, so that our pets are healthier and beautiful.
Supplement vitamins, you need to treat differentiated
Vitamins will change complicated during the preparation of pet food, with physical changes, chemical changes, and even changes in microorganisms. Then, when preparing food for pets, they should be treated according to the special characteristics of vitamin substances: different pets depending on the pets differently The physiological phase and different varieties are strictly grasped; fully consider the loss of vitamins in high temperature steaming; the antagonism and contraindications between vitamins and other nutrients.
I believe that these detailed explanations about vitamins can help owners who have pets to understand how to ensure the nutrition of food love and how to maintain our pets healthy. In fact, many knowledge about pet nutrition lies in the accumulation of bitterness in life. Today, are your favorite pets happy?
