First, nitrite poisoning. Nitrite poisoning is also called "burden disease." Green leaves such as cabbage and radish leaves are rich in nitrate. The Chinese cabbage and radish leaves are corrupted, or they are boiled overnight in a pot, or boiled and placed in a jar for a long time. The nitrate in the dish is converted to highly toxic nitrite. Poisoning occurs when pigs eat, and severe cases die quickly. Symptoms: Sudden illness after eating, mouth foaming, irritability, difficulty in breathing, struggling, visual mucous membranes and skin becoming dark purple, turning pale, shearing ears, cutting tails are not conscious, blood is purple, not easy solidification. Preventive method: Do not feed rotten green fodder to the pig; if you need to cook the green fodder, use acute heat to cook, open the lid, turn it frequently, and boil it with it. Do not soak overnight.
Second, salt poisoning. Due to excessive feeding of salty feeds such as soy sauce residue and salted fish meal. Adult pigs will intoxicate when they eat more than 50 grams of salt, and they will die if they eat 100 to 250 grams of salt. The main symptoms are thirst, runny nose, constipation or diarrhea, as well as neurological symptoms, and finally death from cardiac paralysis. Preventive measures: When feeding pigs with salty feeds, do not give salt, and drink enough water. Add salt to mix well and prevent individual pigs from eating too much and poisoning.
Third, mold corn poisoning. Caused by corn feeding on parasitic molds. Symptoms like menstrual flow, manifested heterophilia, reduced food, and excitement. Therefore, avoid using moldy corn to feed pigs.
Fourth, ricin poisoning. According to the pig's weight per kilogram, 1.4 grams of castor bean would be lethal. Therefore, the castor cake that is not detoxified can not be used as feed. If ramie is used to feed pigs, it must be boiled for more than 2 days to eliminate toxicity. The amount fed must not exceed 10% to 20% of the diet.
Fifth, pesticide poisoning. Pigs that ingest pesticides or feed the pigs with recently sprinkled pesticides can cause poisoning. Organophosphorus pesticides and organochlorine pesticides, mercury preparations, arsenic preparations, and zinc phosphide all cause pig poisoning. Therefore, it is necessary to strengthen pesticide management to prevent pigs from eating and drinking water containing pesticides. If you use a vegetable that has recently been sprayed with pesticides to feed the pig, you must wash the cabbage and confirm it is non-toxic before feeding the pig. Once a pig poisoning is found, the veterinarian should be rescued as soon as possible.
