What nutritional additives are there in feed additives?

When using animal feed equipment, it is necessary to add feed additives, as an indispensable part of compound feed, play an important role in supplementing and improving the completeness of the diet. The addition of these trace ingredients in feed is intended to improve the utilization efficiency of feed and thus improve the production performance of animals. These additives can be divided into two categories: nutritional additives and non-nutritional additives according to their functional characteristics.

Nutritional additives, as the name suggests, are mainly used to supplement the nutrients in feed. They include feed-grade amino acids, vitamins, mineral trace elements, enzyme preparations, and non-protein nitrogen. The addition of these additives makes the feed more comprehensive and balanced, meeting the various nutritional needs required for animal growth and development.

In terms of amino acid additives, arginine, cystine, lysine, methionine and tryptophan are the key limiting amino acids required by dairy cows. The content of these amino acids in general feed is low, so they need to be added to the supplementary feed of dairy cows through artificial synthesis. Among them, lysine and methionine are the most widely used amino acid additives in my country, and their addition can effectively improve the production performance and health level of dairy cows.

Vitamin additives are intended to provide comprehensive vitamin support for dairy cows. Although the rumen of dairy cows can synthesize some vitamins, such as vitamin K and B vitamins, and vitamin C can also be synthesized in the liver and kidneys, in order to ensure the health and production performance of dairy cows, key vitamins such as vitamin A, vitamin D and vitamin E still need to be added.

In addition, mineral additives are also an important part of feed additives. Commonly used mineral additives include ferrous sulfate, ferrous chloride, copper sulfate, copper chloride, zinc sulfate, zinc carbonate, zinc oxide, manganese sulfate, manganese oxide, manganese chloride and potassium iodide. The addition of these minerals helps to supplement the mineral needs of dairy cows and maintain their normal physiological functions and health status.

In summary, feed additives play a vital role in compound feed. By adding these trace ingredients scientifically and rationally, we can improve the completeness of the diet and improve the efficiency of feed utilization, thereby promoting the development of animal husbandry and providing more high-quality animal products for people's healthy lives.
