Causes of moldy feed The moldy feed is caused by mold. The molds are widely found in nature. The actinomycetes mainly include Aspergillus flavus and Penicillium, etc. If the raw materials have not been dried after harvesting, and the humidity is suitable, large numbers of breeds will occur, resulting in moldy rotten feed. It should be particularly pointed out that: Do not only pay attention to the mildew in the rainy season. Even in the cold season, as long as the feed storage environment is humid, or the moisture content of the feed exceeds the standard, mildew will occur. However, mildew will be slower at high temperatures than at high temperatures. Not easy to be noticed by people. In addition, poor ventilation of the warehouse and leakage of water are also causes of moldy feed. When feeding livestock and poultry, each time feeding too much, accumulating for too long, the feeding trough does not clean for a long time, it can also cause mildew. After the moldy feed becomes moldy, its physicochemical properties will change. Physical changes will be manifested in discoloration, rot, fever, and odor. Chemical changes will occur in feed decomposition and nutrient consumption, which will result in feed wastage. Aflatoxin is the most serious hazard in feed moldy metabolites. After the livestock and poultry feed on moldy feed, they will be infected with mycosis, showing loss of appetite or food, mental fatigue, growth inhibition, yield loss, debilitation, anemia and various serious complications, and even death. At the same time, its toxins can indirectly harm human health through livestock and poultry products. Therefore, it is very important to take measures to prevent mildew and detoxification. Moldy Prevention Do a good job of keeping the feed. The warehouse where the feed is stored should be dry and clean. There should be a bottom under the feed, and there must be space above and around the air to allow the air to circulate. Hypoxia mildew. In the rainy season, the storage of the feed is sealed with plastic bags to inhibit mold growth. Acetic acid mildew. Mix 2 parts of acetic acid and 1 part of sodium acetate, then add 1% sorbitol, stir well, dry and mix in feed at 1%. Storage will not be mildew for more than 90 days. Calcium propionate (sodium) mildew. Add 50 grams of sodium propionate or 100 grams of calcium propionate per 100 kilograms of feed. Stir and store in wooden barrels, concrete tanks or plastic bags. Valid for more than 100 days. Ke mold net mildew. 500 g of moldew was added to each ton of batch material and it will not be mildewed for two months and will not be agglomerated. Do a good job of feeding management. Feeds should be given less frequently, and attention should be paid to eliminating agglomeration. Mangers and drinking fountains should be thoroughly cleaned and disinfected. The feed is often turned over to prevent mildew. Mildew detoxification and detoxification. Place mouldy feed in the tank, add fresh water (preferably boiling water), and stir with a wooden stick. After being washed 5 times -6 times, it can be used to feed livestock and poultry. Cooking detoxification method. Put the moldy feed in the pot, add water to boil for 30 minutes, or steam for 1 hour. Remove the water and then use it for detoxification. Lime water detoxification method. The moldy feed is soaked in 10% pure lime water for 3 days, washed with clean water, and dried after detoxification. Ammonia detoxification method. Moisture content of moldy feed was adjusted to 15%-22%. The tank was filled with ammonia gas and then sealed for 12 days to 15 days. After drying, the amount of ammonia was reduced to feed. Sugar detoxification method. The moldy feed is soaked in 1% sucrose solution for 10 hours to 14 hours, then the soaking solution is filtered off, rinsed with water, dried, and then detoxified.
