High temperatures and rain in summer have created problems for the preservation of aquaculture feed. If the formulated feed is improperly stored in a high-temperature environment, mildew will produce toxic and hazardous substances and lose its food value, causing economic losses to farmers. What should you pay attention to in the storage of feed?
1, the temperature
The temperature has a great influence on the storage and storage of compound feeds, because there are nutrients and a small amount of water in the compound feeds, which provide favorable conditions for the survival and reproduction of bacteria. The activity of enzymes in bacteria at a high temperature will increase to some extent, and the activity of bacteria will increase. , Proliferation, rapid decomposition of the components in the compound feed, resulting in spoilage, produce a large number of harmful substances, aquaculture animals eat moldy feed, not only will affect its normal growth, long-term past, toxic and hazardous substances in aquaculture Accumulation in animals will eventually affect the health of consumers. When the temperature is lower than 10°C, mold growth is slow. If the temperature is higher than 30°C, it will grow rapidly and the compound feed will rapidly degenerate. Therefore, the compound feed should be stored in a low-temperature and ventilated place during high temperature. The warehouse where feeds are stored should have the properties of heat insulation, light protection, radiation protection, etc. Therefore, the top of the warehouse should have a thermal insulation layer, trees should be shaded, and the walls should be painted white to reduce heat absorption.
2, humidity
The humidity and moisture in the air also play an important role in the storage of compound feeds. The moisture content of formulated feeds is generally less than 12%. If the humidity in the air is too high, the moisture in the compound feed exceeds this ratio. High temperature in summer, easy to mildew. Therefore, the storage of compound feed should be kept dry during the high temperature period. The double bags should be used for packaging. Except for the surface textile bags, there must be a layer of airtight plastic bags in order to prevent the infiltration of moisture in the air. In order to prevent moisture, compound feed should also be more than 30 centimeters away from the ground when stored, and can not rely on the wall, the ground should be spread straw, rice husk moisture materials, and then a layer of straw mats, and finally stacking compound feed is relatively safe .
