1. Determination of vitamin feed standards. The vitamin feeding standard is the animal's demand for various vitamins. The NRC (National Research Council) standard is the animal's basic requirement for vitamins and can prevent significant vitamin deficiency. The optimum amount of animal vitamins formulated by certain vitamin manufacturers such as Roche refers to the amount of additives that give animals the best health and performance. The optimal amount of Roche vitamins is generally several times to several tens of times higher than the NRC standard. Therefore, when designing and applying vitamin additives, the vitamin feeding standards should be reasonably determined, generally higher than the NRC standard, and Roche can be used when conditions permit. Best demand criteria. It is necessary to consider the influence of various factors such as feed species, animal health status, feeding environment, formulation cost, and storage time, and to be scientifically and scientifically grasped to meet the maximum demand for animal growth and development as far as possible. Especially in stressed animals, the vitamin levels of the feed should be increased. 2. Appropriate over-application. Most of the vitamins are not stable, and they are liable to cause losses and decrease in potency during the processing and storage of feed. In order to ensure that animals receive enough vitamins, they should generally be added in excess. 3. Select vitamin preparations. At present, vitamin preparations have single vitamins and multi-vitamin premixes. According to the actual situation, it can be determined whether they are premixing multiple single vitamins, or choose a number of premixes. Smaller production units use more vitamin premixes. Due to the complexity of vitamin testing and quality judgement, the products of a professional manufacturer with a better reputation should be used. 4. Note the effective content, potency, and stability of vitamins. Most commercially available vitamins are not pure and 100% potency vitamins. Therefore, when purchasing and using vitamins, they should pay attention to their effective content and potency, and reasonable conversion. Different types of vitamins of the same type have different stability. For example, vitamin A palmitate is more stable than vitamin A alcohol, and vitamin E acetate is more stable than vitamin E alcohol. Therefore, it is necessary to use a stable vitamin as much as possible in practical applications. 5. Note the independent addition of choline and vitamin C. Since choline and vitamin C are prone to hygroscopicity and destroy other vitamins, they are generally not premixed with other vitamins and added separately when used. Commercially available multi-dimensional preparations are also mostly free from choline and vitamin C. If multi-dimensional preparations are selected and used, it should be noted that appropriate amounts of choline and vitamin C are independently added according to the feeding standards at the time of application. 6. Flexible adjustment according to the actual situation. The standards for raising vitamins should not be the same, but should be flexibly adjusted according to the actual formula species, feeding environment, weather season and other factors, in order to ensure the animal's demand for vitamins in the actual situation to maintain a good state and production performance. Such as high calcium, phosphorus layer chicken feed, it should be appropriate to increase the level of vitamin A and vitamin D to increase calcium and phosphorus absorption and utilization. 7. The necessary dilution and preservation. Because vitamins are used in small amounts, and they may react with each other and with other additives, which can damage the potency, it is advisable to carry out a relatively large dilution before use, reduce the concentration, and then premix with other vitamins and additives. Especially when premixed with choline, trace elements and acid-alkaline additives, dilution work should be done to ensure better mixing uniformity and higher potency. The commonly used carrier for vitamin dilution and premixing is defatted corn starch. Vitamin products are sensitive to external factors such as light and heat and are prone to failure. Therefore, they should generally be stored in a low-temperature, airtight, and dry environment. It should be used as soon as possible after unsealing. The storage period should not exceed 1 month.

How to apply vitamin feed additives rationally
Vitamins are catalysts for biochemical reactions and metabolism of animal organisms and are indispensable for the maintenance of animal normal physiological functions and the maintenance of normal growth and development of animals. The lack of vitamins in animals will have significant adverse effects on growth and development. Therefore, vitamins must be added to the daily feed for the body's needs.
