Vitamin E is a biocatalyst, which can regulate carbohydrate metabolism, promote the maturation of gonads and reproductive function, is closely related to the reproduction of livestock and poultry, and plays a role in promoting conception and preventing miscarriage.
Sufficient vitamin E added to feed can promote animal system development, reduce morbidity, mortality, and increase animal weight gain.
Vitamin E can also accelerate the synthesis of gonadotropins in the anterior pituitary of animals and improve reproductive performance, thereby increasing the number of litters and eggs in animals.
