When we are in production practice, how to use vitamin reasonable is relatively headache for us. General nonnutritive additive is depend on the breed standard. Raise the requirements of vitamins that listed standard should be minimum requirements, animal breeding in neutral temperature area, good health conditions in the amount from the feed.

But in production, considering environmental conditions and feed processing, feed storage time, composition, production level and feed healthy breeding objects larger changes, according to production experience, so the amout of vitamins tha added into feed additives should be higher than the suggest amount of breed standard.

In the daily breed, recommended amount of vitamins are larger than the general breed standard requirements. Production of vitamin products company proposed the recommended amount of scientific workers or varieties are larger than the recommended amount of company, should be generally science worker or varieties of the recommended amount of company. Feed manufacturer’s recommended by vitamin production quantity of vitamins may raise the animal health and store inside body has certain advantages in economic efficiency, but not necessarily achieve ideal result, vitamin reasonable add will greatly promote healthy growth of animal feed producers get good economic benefits. According to the test results, and the production of feeding effect, each kilogram feed minimum vitamin content suggest consider the following factors:

First general plant in feed that does not contain vitamin A and vitamin D, even after this technology vitamin A and vitamin D is easy to deactival and so recommended amount of vitamin A and vitamin D should be larger several times than the requirement. Recommended amount of vitamin K and vitamin E should be higher 3 to times than the requirement amount.

Second, the added amout of vitamin B2 and vitamin B5 should be raised above the standard requirement and improve 1.5 times ~ 2 times.

Third feed vitamin B1 and vitamin B6 are rich in commmon feed, dosage is less breed standard requirements to reduce costs. Animal feed and cake feed contains more replacement choline, so added amout should be lower than raising standards requirement.
