1. Keep it cool and dry. Long-term preservation of feed additives must be done under low temperature and dry conditions. When the storage temperature is 15-26 degrees Celsius, unstable nutritional feed additives will gradually lose their activity, and the summer temperature will be high and the loss will be greater. When the temperature is 24 degrees Celsius, the stored feed additives can lose 10% per month, and at 37 degrees Celsius, the loss can reach 20%. Drying conditions are also important for the preservation of feed additives. When the air humidity is high, the feed is prone to mold. Due to the multiplication of various micro organisms, general feed additives are easy to absorb water. As a result, a water film is formed on the surface of the additive, which accelerates the denaturation of the additive.

2. The influence of the melting point, solubility, and pH of feed additives on storage and storage. Feed additives with low melting point have poor stability. The melting point starts to decompose at 17-34 degrees Celsius. Easily soluble feed additives, due to their low content, are prone to decomposition reactions in the liquid state. Some feed additives are very sensitive to acidity and alkalinity. In a humid environment, the microparticles of feed additives can easily form a wet film, which will produce a certain degree of acidity and affect stability.

3. The effect of storage period and particle size on the quality of feed additives. The stability of fine-grained feed additives is poor, and with the extension of storage time, it can cause more losses. Even if the vitamin feed additives are stored under low temperature and dry conditions, the monthly natural loss is 5%-10%. For any kind of feed additive storage, due to high pressure can cause particle deformation, or after pressurization, the surface of adjacent components will form a micro-thin film, which increases the exposed area and accelerates decomposition.

4. Add antioxidants, antifungal agents, reducing agents, stabilizers. In order to avoid the occurrence of similar ferrous sulfate, ascorbic acid, sulfite reducing sugar iodine, etc., causing oxidation or reduction reactions of certain feed additives, destroying their solid effective value, it is very useful to add appropriate amounts of antioxidants and reducing agents to additive feeds. necessary. Because feed is prone to deliquescent in a humid environment, and mildew occurs under the action of bacteria, molds and other micro organisms, it is very necessary to add an appropriate amount of antifungal agent to the feed. Different stabilizers have different effects on additives. For example, comparing capsule vitamin A with fat vitamin A, when stored in an environment with a humidity of 70% and a temperature of 45 degrees Celsius, the vitamin A titer of cod liver oil can be found after 12 hours. The loss is greatest, and the potency of Capsule Zhuang is highest.
