Vitamin E chemical structure
CAS NO.: 10191-41-0
Formula: C29H50O2
Molecular Weight: 430.71
Vitamin E is an antioxidant but susceptible to oxidize and destroy in the feed, its physiological activity will disappear as a protective agent for other vitamins.If as an animal nutrition, it also needs antioxidants with stability treatment.
So, Vitamin E acetate as a good solution!

BOAR PIGS
Showed testicular degeneration,
liver necrosis, nutritional muscle
disorders and immunity reduction.
RUMINANTS
Mainly for muscular dystrophy.
Calves and lambs appear white muscle.

POULTRY
Breeding performance dysfunction,
embryonic degeneration, softening of
the brain, red cell hemolysis, plasma
protein reduced, kidney degeneration,
exudative diathesis disease, adipose
tissue discoloration, muscular dystrophy, and decreased
immunity, etc.
Why to use Vitamin E
Maintain animals normal reproductive performance, prevent softening of the brain and muscular dystrophy, related close to livestock’s immunity。Vitamin E plays a very important role to keep livestock healthy in humoral and cellular immunity
1. ENHANCE ANIMAL HUMORAL IMMUNITY
2. IMPROVE ANIMAL CELL IMMUNITY
3. PROMOTE LIVESTOCK AND POULTRY IMMUNE SUBCULTURE EFFECT
4. IMMUNE ENHANCEMENT AND SYNERGISTIC EFFECT
Anyway, vitamin E can increase the level of animal anti-oxidation, maintain the integrity of the cell membrane structure, improving livestock humoral and cellular immunity, used as an effective immune enhancer, stimulates the body to produce adequate immune response and a high titer antibodies to exert long-lasting effects of immunization, improve vaccine effectiveness and extend its durability.
As for vitamin E further research, vitamin E maintain healthy growth and normal function of the immune system, as well as disease prevention, etc., will play an increasingly important role.
Stability of springbio powder particles
Vitamin E acetate powder particles structure
Starch
Matrix
Vitamin E
Antioxidant
Vitamin E as an anoxidant, sensitive to oxygen
and oxidants, unsensitive to heat and acid.
Springbio vitamin E acetate powder particle is utilized with the advanced technology of two layers embedded. Vitamin E molecular treated by antioxidant stabilization processing was embedded in the matrix of the newwork structure, and then the matrix surface is to coat a layer of starch and form a round, compact, uniform particle, to ensure its stability for storage.
A large number of accelerated tests showed springbio’s vitamin E series with good stability itself, such as storing 180 days under 40℃ vitamin E retention rate is still more than 90%, equivalent to a world-class product, much higher than domestic similar products.
