Thiamine usually appears as its hydrochloride [2], molecular formula C12H17ClN4OS·HCl, molecular weight 337.29.Also known as
thiamine hydrochloride.White crystalline powder.Have weak special smelly, taste bitter, have deliquescence sex.Melting point 248℃,
soluble in water, slightly soluble in ethanol, insoluble in ether and benzene.Vitamin B1 has the function that maintains normal
candy metabolization and nerve conduction, use at treating beriberi and central nerve reach gastroenteric disease, heart activity
maladjusted.Yeast has the highest content of vitamin B1 in nature.It can be synthesized by 2-methylfuran and vinyl nitrile or by
betathoxypropionate and ethyl formate.[3]
Thiamine, also known as thiamine or antineuritis, was the first vitamin to be found. It was made from fungi, microbes and plants,
but animals and humans could only get it from food.Vitamin B1 mainly exists in the husk and germ of seeds, such as rice bran and
bran content is very rich, in yeast content is also extremely rich.Thiamine is a combination of pyrimidine and thiazole rings and
is involved in sugar metabolism in the body.

Application in aquatic products
Because of the extensive role of vitamin B1 in aquatic animals, the long-term shortage of vitamin B1 not only affects its growth,
but also produces a series of deficiency diseases through the obstacle of metabolic response in the body.The study found that
shrimp, crab and other crustaceans can not synthesize vitamin B1 or the amount of synthesis is very small, difficult to meet their
physiological needs, so must be obtained through artificial feeding.Some scholars studied the contents of vitamin B1 promoting
sugar metabolism in penaeus chinensis, and found that it was necessary to ensure that its vitamin B1 diet was 60mg/kg in order to
make full use of the sugar source in the bait.

Application in poultry production
Vitamin B1 also plays an important role in the growth of poultry.Dietary addition of thiamine above 1.0mg/kg significantly
increased body weight gain (P<0.01) in 3-week-old and 4-7-week-old broilers, with requirements of 4.0mg/kg and 1.6mg/kg for
0-3-week-old broilers, respectively.Therefore, vitamin B1 is indispensable in poultry feed formula.

Application in ruminant production
Vitamin B1 has a special nutritional effect on ruminants.The study found that during the peak period of lactation, cows were prone
to not eating concentrate, which led to a decrease in milk production, which could be intramuscular injection of 0.25% vitamin B1
30mL, and the light ones started to eat materials in 2d after injection, while the heavy ones needed to return to normal after 2-3
times of medication.Other studies have found that Wernicke's encephalopathy is caused by a lack of thiamine due to a long period
of fasting. It is mainly treated with vitamin B1, which can be recovered after timely diagnosis.Additional, vitamin B1 is in cure
bovine ketone body disease, horse flesh red albuminuria is ill in specific medicaments, be in when organic phosphorous poisoning,
food is toxic and medicaments toxic use extensively.
Vitamin B1 is usually added in the form of multi-dimension in the feed. When adding, the type and growth stage of the animal
should be considered to ensure the best production performance.
