Emphasis should be placed on the prevention of mildew during storage before and after corn harvest. 1. Corn must be harvested in time after ripening, dried thoroughly, and stored in ventilated condition. Second, once found poisoning livestock and poultry, immediately stopped the moldy corn, switch to fresh feed. Third, mild corn mold can be used with other feeds. At the same time, soaking the corn with 3 times the weight of fresh water for a day and night, and then changing for the same amount of fresh water for 1-2 hours, so that changing the water continuously for 3-4 times, most of the toxins can be leached by fresh water, and then taken out and dried to be used as feed. If 10% lime solution is used instead of fresh water to soak moldy corn, the detoxification effect will be better. Fourth, the treatment of poisoned pigs, available mung bean 50 grams, 20 grams of licorice Jianshui mixed feed or into the sink for their own drink, once every 7-10 days. White sugar mixed feed can also be used. Each pig uses 20 grams twice a day for 7-10 days. Healthy pigs eat a small amount of mild mildew corn and rarely develop the disease. Pigs with other conditions such as atrophic rhinitis are less likely to be cured with concurrent poisoning. The use of antibiotics and atropine was not effective in the early stage of poisoning, and detoxification was effected by the addition of mung beans and licorice Jianshui.
