Vitamin nutrition in high yielding dairy cows

Vitamins are a class of nutrients used by animals to maintain normal growth, production, reproduction and health. Cows, like other animals, need vitamins to maintain optimal production performance and health. Different from pigs, chickens and ducks, dairy cows are herbivorous livestock. Compared with water-soluble vitamins, fat-soluble vitamins are more likely to be deficient, so the nutrition of vitamins A, D and E is particularly important. However, under the conditions of stress or high yield, B vitamins need to be added to the diet of dairy cows, which changes the traditional view that B vitamins exist in natural feed, and B vitamins synthesized by rumen microorganisms can fully meet the requirements of adult ruminants for B vitamins.
