The cause of a moldy mold The reason for the mildew of the feed is that the mold is caused by mold. Molds are widely found in nature. The fungi-producing bacteria mainly include Aspergillus flavus, Penicillium, etc. If the raw materials are not dried after harvesting and the humidity is suitable, the feed will be sore. It is important to note that: Do not only pay attention to the mildew in the rainy season. Even in the low temperature season, as long as the feed storage environment is wet, or the feed water content exceeds the standard, the feed will also be mild, but the mildew will be slower than the high temperature. Not easy to be detected by people. In addition, poor ventilation in the warehouse and water leakage are also the cause of the mold. When feeding livestock and poultry, each time the feed is too much, it will accumulate for too long, and the feeding trough will not be cleaned for a long time, which will cause mold. Second feed moldy hazard Moldy hazard After the mold is mildewed, its physical and chemical properties will change. Physical changes are manifested in discoloration, decay, fever, and odor; chemical changes are manifested in feed decomposition and nutrient consumption, resulting in waste of feed. Among the metabolites of moldy feed, aflatoxin is the most harmful. When livestock and poultry feed on moldy feed, they will be infected with mycosis, showing loss of appetite or loss of food, mental illness, growth inhibition, reduced yield, weakness, anemia and various serious complications, and even death. At the same time, its toxins can indirectly endanger human health through livestock and poultry products. Therefore, it is very important to take measures to prevent mildew and detoxification. Three feed anti-mildew method Moldy prevention to ensure the preservation of feed: the warehouse where the feed is kept should be dry and clean. The bottom of the feed should have a bottom, and the space should be left and around to allow air to circulate. Hypoxia and mildew. In the rainy season, the storage feed is sealed with a plastic bag to inhibit mold growth. 1 Acetate mildew: Mix 2 parts acetic acid and 1 part sodium acetate, add 1% sorbitol and mix well. After drying, mix in 1% ratio. It will not be moldy after more than 90 days of storage. 2 Calcium propionate (sodium) anti-mildew: add 50 grams of sodium propionate or 100 grams of calcium propionate per 100 kilograms of feed, mix well, store in wooden barrels, cement pools or plastic bags, valid for more than 100 days. 3 gram mold and mildew proof: add 500 grams of gram mold to each ton of compound, no mildew in two months, no agglomeration. [NextPage] Four feed detoxification method 1 Litsea cubeba oil detoxification method According to the ratio of 10 mL of Litsea cubeba oil per 100 kg of moldy feed, put the oil into the bottle, tie the bottle with three layers of cloth, and then bury the bottle in the feed. After 7 days of sealing, it can be detoxified. 2 water immersion method It is suitable for the detoxification treatment of seed feed and is divided into two forms. First, mix the mildew particles and water in a certain proportion, stir, stand still, soak for a period of time, wipe the particles with a rag, remove and dry in a ventilated place. The second method is to grind the seed feed into 1.5 to 4.5 mm particles, then add 3 to 4 times of water, stir, stand still, soak for about 30 minutes. This is repeated 2 to 3 times, and the toxic component or the bacterial metabolite floats on the surface due to the specific gravity less than water, and then it can be filtered off. 3 sucrose solution detoxification method The moldy cake feed such as peanut cake, crepe cake, rapeseed cake, processed and broken, soaked in 1% sucrose solution for 10 ~ 14 h, then rinsed with water, dried in the drying field, you can reach The purpose of poisoning. 4 ammonia detoxification method Treatment of mildewed feed with ammonia or ammonia can reduce the content of aflatoxin in the feed by 90% to 95%. Add 12.5～17.5 g of ammonia water per 1 kg of mildewed feed. After mixing in a large container, seal the container mouth with plastic cloth and let it stand at room temperature for 3-7 days to achieve detoxification. This method is suitable for detoxification of bran feed. Detoxification method of soybean powder: When the relative humidity is 50%, 2% urea is added to the soybean powder as urease zymogen, and sealing for 10 hours can destroy more than 70% of aflatoxin. 5 clay or zeolite treatment The aluminosilicate can selectively bind to aflatoxin B1, and its adsorption rate to the toxin is over 80% in aqueous solution. A common method is to add 0.5% clay or zeolite to the feed, which can promote the growth and development of livestock and poultry toxins. 6 Fermentation neutralization and detoxification Wet the moldy feed with water, mix well, the water content is 50% ~ 60%, make a heap, let it ferment naturally for 24 h, then add 2% of the plant ash, mix well, neutralize for 2 h, then put it in the bag, Rinse with water, filter off the ash water of the plants, pour the bran 1 times, ferment at room temperature for 7 h, the detoxification effect can reach more than 90%. 7 lime water detoxification method The mildewed feed is soaked in 10% pure lime water for 3 days, then washed with water. After drying, it can be detoxified, and the detoxification rate is 90% to 99%. 8 baking soda to poison Pour 50 kg of moldy feed into the pot, add 1% baking soda 100 kg, first boil with simmer, then cook over low heat until the granules break open for half an hour, then stop and cool, remove and rinse with water. Can be fed. 9 cooking detoxification method Put the moldy feed into the pot, add water to boil for 30 minutes or cook for 1 hour, then wash it with water several times, remove the water to remove the poison. 10 mechanical detoxification method Mild moldy corn and wheat, most of which are distributed in the germ and seed coat, as long as the germ and bran are removed by mechanical processing, the purpose of detoxification can be achieved. 11 manual screening detoxification method The feed is screened by mechanical or manual methods, the moldy feed is removed, and the unmutaged feed is further dried to achieve the purpose of detoxification and mildew prevention. It is mainly suitable for detoxification of straw and pellet feed. 12 baking heating detoxification method For the cake material, baking at 150 ° C for 30 min or microwave for 8-9 min, 48% to 61% of aflatoxin B1 and 32% to 40% of aflatoxin G1 can be destroyed. 13 drying and detoxification This method is mainly used for the detoxification treatment of straw feed. The moldy feed is first dried in the sun, then ventilated and shaken to remove the mold's spores, making it harmless and non-toxic. 14 de-embryo detoxification This method is mainly used for detoxification of corn, because the toxin of moldy corn is mainly concentrated in the embryo of corn. First grind the corn into small pieces of 1.5 to 4.5 mm, add 5 to 6 times of water, and then stir. The pieces of the embryos float on the water surface due to lightness, and then remove them. This can be repeated several times. The purpose of degerming and detoxification. 15 Radiation detoxification method For the feed that has been contaminated with mold or is likely to be mildewed and tempered, it can be sterilized by ultraviolet irradiation. The ultraviolet ray can effectively kill the mold and destroy the structure of aflatoxin to achieve the purpose of detoxification. 16 VC detoxification method VC blocks the epoxidation of aflatoxin B1, thereby preventing its oxidation to the active form of toxic substances. Adding a certain amount of VC to the diet and feed, together with the right amount of amino acids, is an effective way to overcome aflatoxin poisoning. 17 adsorption detoxification method The mycotoxin adsorbent can effectively remove toxins from moldy feed. It is the function of adsorbing toxins in livestock and poultry by the mycotoxin adsorbent, so as to achieve the purpose of detoxification, simple and safe. 18 lactic acid bacteria fermentation detoxification method Fermentation with lactic acid bacteria converts aflatoxin B1 into less toxic aflatoxin B2 under the catalysis of the enzyme. Treating the feed in this way not only reduces the toxicity of the enzyme toxin in the feed, but also increases the feed nutrient (bacterial protein) and improves palatability. It should be noted that the above treatment method is only suitable for mildly mildewed feed, and should be mixed with other feeds after treatment, and it is forbidden to be fed as the main feed. For feeds that are severely mildewed, it is better to dispose of them because of the high cost of treatment.
