The use of vitamins in production practice is a headache. General nutritional additives are determined according to feeding standards. The vitamin requirements listed in the feeding standard should be the minimum required amount, which is the amount that the poultry is in the neutral temperature zone and is obtained from the feed under healthy conditions. However, in production, due to environmental conditions, feed processing technology, feed storage time, feed composition, livestock production level and health conditions, the amount of feed added is recommended according to the feeding standard. The amount is high.
The recommended amount of vitamins in the diet (http://) is generally greater than the required amount in the feeding standard. The recommended amount of the company that produces vitamin products is greater than the recommended amount of scientific workers or varieties of companies, generally should refer to the recommended amount of scientific workers or varieties of companies. The amount of added vitamins recommended by the vitamin manufacturer in the feed may have certain benefits for the health of the livestock and the storage of the body, but the economic benefits may not achieve the desired result. The reasonable addition of vitamins will greatly promote the healthy growth and development of the livestock and poultry. Get better economic benefits. Based on a large number of test results and production feeding effects, the following factors are recommended for the minimum vitamin content per kilogram of feed.
1General plant-based feed does not contain vitamin A and vitamin D. Even though vitamin A and vitamin D are easily inactivated by encapsulation technology, the recommended amount of vitamin A and vitamin D should be several times larger than the required amount. Times. The recommended amount of vitamin K and vitamin E should be 3 to 5 times higher than the feeding standard.
2 The amount of vitamin B2 and vitamin B5 should be increased by 1.5 to 2 times higher than the standard of feeding standards.
3 Commonly used feeds are rich in vitamin B1 and vitamin B6. In order to reduce costs, the dosage can be lower than the standard requirement for feeding. Animal feed and bean cake feed contain more choline, so the amount of addition should be lower than the standard requirement of feeding. At the same time, choline chloride is alkaline. When combined with other vitamin additives, it affects the potency of other vitamins. Generally not mixed, it should be added separately.
4 Biotin is rich in feed, which can be reduced compared with the required amount; biotin is high in price, and there is no good economic benefit when adding a certain amount, so no biotin is added to many commercial vitamins.
5 other vitamins folic acid, vitamin B12, pantothenic acid can be added as needed, the content of the feed as a safe amount.
The amount of vitamin additive added is generally 200 to 300 grams per ton of feed.
