The temperature and humidity in the summer are more suitable for the growth and reproduction of molds that are parasitic on the feed. In the process of growth and reproduction, molds consume nutrients that are the most easily used in feeds and reduce the nutritional value in feeds. The seriously moldy feed can not only reduce its utilization value to zero, but also release a large amount of toxic substances, which will directly harm the safe production of livestock and poultry fish. When it is serious, it will also cause a large number of animal and fish poisoning to die, causing economic losses. In addition, mycotoxins also indirectly endanger human health through animal (water) products. 1, prevention (1) Do not purchase feeds with high moisture content; (2) Do not store feeds with high moisture for too long, and use them as soon as they are fresh; (3) Seal the feed well with plastic bags, and tie the bags after each use. (4) Adopt measures such as ventilation and baking to control the moisture content of the feed in the safe storage requirements; (5) Keep the feed in a ventilated, cool and leak-proof place, and put it under the feed to keep the feed dry and clean. (6) Add the fungicide to the feed with moisture content higher than the upper limit of safe storage moisture content; (7) Add less feed to the feed, and frequently clean the feed tank to prevent feed accumulation. 2, moldy feed detoxification Re-use of mildew feed must be prudent and scientific. Mild mildew feeds must be scrapped. Mild mildew feeds can be detoxified by the following methods. (1) Selection method Hand or mechanical selection, remove mildew feed. (2) Washing method Place the moldy feed in the tank, add fresh water and open it, stir with a wooden stick, and wash it 5-6 times for four livestock and poultry. (3) cooking method Put the moldy feed into the pot for 30 minutes or steam for 1 hour. Remove the water and feed it. (4) Lime water detoxification The moldy feed was put into 10% pure lime water, soaked for 3 days, then rinsed with water and dried to achieve the detoxification effect. (5) Ammonia method The amount of ammonia in moldy feed was adjusted to 15%-22%, filled into a cylinder, and ammonia gas was introduced. The ammonia was sealed for 12-15 days and then dried for feeding. (6) Fermentation neutralization method The mildew feed should be moistened with appropriate amount of water and mix well so that the water content is 50%-60%. After 24 hours of stacking, add ash to the plant ash, mix well, neutralize it for 2 hours, then put it in a bag, rinse with water, and remove the gray water from the plant. The rice bran or wheat bran was fermented at room temperature for 7 hours, and its detoxification effect was over 90%.
