Products Description

Vitamin B1 is also known as thiamine or anti-neuritis vitamin. It is synthesized by fungi, microorganisms and plants. Animals and humans can only obtain it from food. Vitamin B1 is mainly found in the outer skin and germ of seeds, such as rice bran and bran, where it is abundant. It is also very abundant in yeast. Thiamine is formed by the combination of pyrimidine ring and thiazole ring and participates in sugar metabolism in the body.

Thiamine is commonly found in the form of its hydrochloride salt [3], with the molecular formula C12H17ClN4OS·HCl and a molecular weight of 337.29. It is also known as hydrochloride thiamine. It is a white crystalline powder. It has a faint peculiar odor, a bitter taste, and is hygroscopic. Its melting point is 248℃. It is soluble in water, slightly soluble in ethanol, and insoluble in ether and benzene. Vitamin B1 has the function of maintaining normal sugar metabolism and nerve conduction. In nature, yeast contains the highest amount of vitamin B1. It can be synthesized from 2-methylfuran and ethylenediamine, or from β-ethoxycaproic acid ethyl ester and ethyl formate, etc.

Products Application

Aquatic Products
Since vitamin B1 plays a widespread role in aquatic animals, a long-term shortage of vitamin B1 not only affects their growth but also causes a series of deficiency symptoms through metabolic disorders in the body. Research has found that crustaceans such as shrimp and crabs cannot synthesize vitamin B1 or do so in very small quantities, which is insufficient to meet their own physiological needs. Therefore, they must be obtained through artificial feeding. Some scholars have conducted research on the content related to vitamin B1 promoting sugar metabolism in Chinese prawns, and found that it is necessary to ensure that the vitamin B1 diet for prawns is 60mg/kg in order to enable prawns to fully utilize the sugar sources in the feed. Poultry
Vitamin B1 also plays an important role in the growth of poultry. Research has shown that adding more than 1.0mg/kg of thiamine to the diet significantly increases the body weight gain of 3-week-old and 4-7-week-old broilers (P < 0.01). The required amounts for 0-3 weeks and 4-7 weeks old broilers are 4.0mg/kg and 1.6mg/kg respectively. Therefore, it can be concluded that vitamin B1 is indispensable in poultry feed formulas.
Ruminants
Vitamin B1 has a special nutritional function for ruminants. Research has found that dairy cows are prone to a situation where they refuse to eat concentrate feed during the lactation peak, resulting in a decrease in milk production. This can be alleviated by intramuscular injection of 0.25% vitamin B1 at 30mL, with mild cases starting to eat feed on the second day after the injection, and severe cases requiring 2-3 doses of medication before returning to normal. Another study has found that Wernicke encephalopathy is caused by long-term fasting, leading to a deficiency of thiamine and subsequent onset of the disease. It is mainly treated with vitamin B1, and if diagnosed promptly, most cases can recover after treatment. Additionally, vitamin B1 is a specific drug in the treatment of ketosis in cows and myoglobinuria in horses. It is widely used in cases of organophosphorus poisoning, food poisoning, and drug poisoning. Vitamin B1 is usually added to the feed in a multivitamin form. When adding it, factors such as the type of animal and its growth stage should be taken into account to ensure the best production performance.
