Feed mold is caused by mold. If the raw materials haven't been dried after harvesting, and the humidity is suitable, it will multiply and cause rotten feed. It should be particularly pointed out that even in the cold season, as long as the feed storage environment is wet or the moisture content of the feed exceeds the standard, mildew will also occur. In addition, poor ventilation of the warehouse and leakage of water are also causes of moldy feed. When feeding livestock and poultry, excessive feeding and accumulation for too long can also cause mildew. After the feed becomes moldy, its physicochemical properties will change. 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, the warehouse where the feed is stored should be dry and clean. There should be a bottom under the feed, and there should be gaps above and around to allow the air to circulate. There are generally the following kinds of anti-mildew law: 1. Hypoxia mildew. In the rainy season, the storage of the feed is sealed with plastic bags to inhibit mold growth. 2. 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. 3. Calcium propionate (sodium) mildew. Add 50 grams of sodium propionate or 100 grams of calcium propionate to each kilogram of feed. Stir and store in wooden barrels, concrete pools or plastic bags. Valid for more than 100 days. 4. 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.
