Control of moisture, low temperature storage in the storage process is subject to high temperature, high humidity is the main cause of feed mold. Because high temperature and high humidity can not only stimulate the activity of lipases, amylases, proteases and other hydrolytic enzymes, speed up the decomposition 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 Hot and humid, resulting in mild heat of the feed. Therefore, when storing 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 anti-microbial, to avoid mildew during storage, transportation, sale and use. A large amount of mold not only consumes and decomposes nutrients in the feed, reduces the feed quality, and reduces the pay, but also causes diarrhea, enteritis, etc. in the livestock and poultry that feed this feed, and can cause severe 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 adopt physical or chemical means to prevent mold and bacteria, such as the addition of moldy agents in the feed.
In short, the compound feed should be stored in a low temperature, dry, dark and clean place. Under normal circumstances, the storage period of granular compound feed is 1 to 3 months; the storage period of powdered compound feed should not exceed 10 days; the storage period of powdered concentrated feed and pre-mixed feed are respectively due to the addition of appropriate amounts of antioxidants. It is 3~4 weeks and 3~6 months.
