The type of toxin contained in moldy corn and its treatment
2022-08-22 07:04:41
Corn is the main raw material for livestock and poultry diets. Feeding a diet containing moldy corn for a long time will not only harm the animals, but harmful substances that remain in the animals will also cause hidden dangers to human health. After moldy corn, it will be contaminated with mycotoxin, mycotoxin.
1, the type of corn mycotoxins
1.1 fumonisin: damage to the respiratory tract, mainly as dyspnea, gasping, shortness of breath, and some also showed drowsiness, loss of appetite, weight loss, thirst and fever, late diarrhea, necropsy chicks visible lung There is a yellow-white caseous necrosis nodule on the balloon.
1.2 aflatoxin B1: damage to the liver, can cause liver cell degeneration, necrosis, acute liver injury; subcutaneous hemorrhage; reduced cock semen volume; embryonic death leads to reduced hatching rate; egg production declines, takes weeks to recover, egg change Small, yolk weight loss; cause immunosuppression, induce coccidiosis, Marek, Salmonella and so on.
1.3F-2 Toxin: Harmful to the genital tract and sex hormone-sensitive tissue, with similar estrogen effects, some chickens showed a false hen, lesions of ovarian swelling, fallopian tube damage, while leading to decreased egg weight, eggshell thickness, pigmentation Poor.
1.4T-2 toxin: invade the oral mucosa of chickens, resulting in corrosive and exudative damage, manifested as oral ulcers, salivary glands and mucous glands squamous tissue deformation, chicken egg production decreased, shell eggs increased.
1.5 ochratoxin: damage to the kidneys, manifested as white urate deposition in the kidney; immunosuppression; early embryonic death, reduced fertilization rate and hatching rate and increased embryo malformation rate; diarrhea, weight loss and so on.
2. Treatment measures for lightly polluted corn
2.1 Dilution A small amount of mild mildew corn was gradually incorporated into normal corn several times.
2.2 washed mildew corn crushed, add 3-4 times the water, stir static soak, change the water twice a day, until the soaking water from the brown color become colorless, wash as soon as possible after use.
2.3 De-emergence and detoxification MxQ China Feed Industry Information Network - Based on feed, serving the toxins of livestock, moldy corn is mainly distributed in the germ part of corn. First grind the corn into small particles of 1.5-4.5mm, add 5-6 times of clean water, and then stir. The germ debris will float on the water because of its lighter density, remove it or drain it with water. Second, you can achieve the purpose of removing germs and detoxification.
2.4 Physical adsorption Minerals capable of adsorbing and capturing mycotoxin molecules - aluminum silicate, zeolite, bentonite, activated carbon, diatomaceous earth, etc., or bovine serum albumin, esterified mannooligosaccharides, etc. are used.
2.5 Chemical treatment Lime water, soda, hydrogen peroxide, or synthetic salt laxatives such as magnesium sulfate are used.
2.6 Supplemental Nutrient Supplements Adequate VA, VD, VE, VK, folic acid, organic selenium, methionine, etc. to alleviate poisoning effects, or use of organic acid additives, probiotics such as lactic acid bacteria, yeasts, etc. may also help to reduce the toxicity of mycotoxins. Some enzyme preparations also help to alleviate mycotoxins.
3. Severely contaminated corn The corn with milder mildew should be collected, stored in special warehouses, sent to the quality inspection agency for inspection in time, and corn that has been tested for excessive levels of toxins can only be sold as industrial foods, and must not be used for food and food. Feed processing, serious mold must not be destroyed.
The above are the treatment measures for mold-contaminated corn. It is recommended that the use of moldy corn is best prohibited in the feed. Even mildly contaminated corn will cause great harm to livestock, poultry and humans.
