Controlling moisture, low temperature storage during storage, suffering from high temperature, high humidity is the main cause of mildew in feed. Because high temperature and high humidity can not only stimulate the activity of hydrolase such as lipase, amylase and protease, accelerate the decomposition rate of nutrients in feed, but also promote the reproduction and growth of harmful organisms such as microorganisms and stored grain pests, resulting in a large number of Damp heat, causing fever and mildew in the feed. Therefore, when storing the feed, the relative humidity of the air is required to be below 70%, and the moisture content of the feed should not exceed 12.5%.
Anti-mildew and bacteria, avoiding mildewing in the process of storage, transportation, sale and use. A large amount of mold not only consumes and decomposes the nutrients in the feed, but also lowers the quality of the feed and lowers the remuneration. It also causes diarrhea and enteritis in livestock and poultry that consume this feed, which can cause serious death. Practice has proved that in addition to improving the storage environment, the most effective way to extend the shelf life of the feed is to take physical or chemical means to prevent mildew, such as adding mold remover to the feed.
In short, the compound feed should be stored in a place that is cold, dry, protected from light and clean. Under normal circumstances, the storage period of granular compound feed is 1~3 months; the storage period of powder compound feed should not exceed 10 days; the powdered concentrated feed and premixed feed have different storage period due to the addition of appropriate amount of antioxidants. It is 3~4 weeks and 3~6 months.
