If pig farms (households) improperly mix or improperly feed the pig's feed, it can easily lead to feed poisoning. The first-aid methods for common feed poisoning in pigs are described below. Moldy feed poisoning Feeding mildewed animal feed can easily cause mild feed poisoning. Suffering from pigs will show loss of appetite or loss of appetite, hair irritability, corneal turbidity, and varying degrees of diarrhea and neurological symptoms, and finally fainting to death. First aid can be given to poisoned pig oral artificial salt laxatives (such as magnesium sulfate, sodium sulfate), toxins as much as possible, and with intravenous injection of 40% atropine 2 ml ~ 3 ml, subcutaneous injection of 25% camphor water 5 ml ~ 10 ml, intravenous Inject 250ml ~ 500ml glucose physiological saline to relieve poisoning. Salt poisoning In the early days, the body temperature of pigs was normal, and they only showed lassitude. They were reluctant to eat, and they were extremely thirsty. They were accompanied by symptoms such as mouth foaming, abdominal pain, constipation or diarrhea and sometimes blood in the stools. If salt poisoning occurs in pigs, feed containing high salt content should be immediately stopped, pigs should be put on tip and tail tip, and pigs should be given intravenous magnesium sulfate (0.1 g/kg body weight) and 10% glucose injection. 250 ml to 500 ml, 1 injection at 6-hour intervals, 2 to 3 consecutive injections to cure. Distillery poisoning If the proportion of pig distillers' grains is too high, vinasse poisoning can easily occur. Symptoms of poisoning are: irritability, excitement barking, mucous membrane flushing, walking squatting, abdominal pain and diarrhea; chronic poisoning with dyspepsia, jaundice, dermatitis, hematuria and other symptoms. First aid can be immediately injected 10% to 20% sodium plus 5 ml to 10 ml, intravenous glucose saline 500 ml, and with oral 5% soda solution 1000 ml to 2000 ml. Nitrite poisoning Some green feeds such as cabbage, beets, cabbage, radish leaves, kale, and some wild green feeds contain high levels of nitrate. This type of green fodder can be converted into nitrite by depositing it for too long, yellowing, or being boiled in a temperature of 40°C to 60°C for a long time. Nitrite poisoning occurs when the pig feeds. . Suffering from pigs, it will show flustered uneasiness, rapid heartbeat, difficulty in breathing, vomiting and runnyness, cold extremities and ears, trembling and convulsions in body, drop in body temperature, serious fall in the ground, foaming in the mouth, Soon coma suffocated and died. First aid should be carried out as soon as possible on the affected pig to perform bloodletting on the tip and tip of the pig, and immediately intravenous or intramuscular injection of 1% methylene blue solution (pig injection per kilogram of body weight 1ml), or intravenous injection of toluidine blue solution (pig injection 5ml per kg body weight ), And cooperate with the pig orally or large doses of Vitamin C injection, and intravenous glucose injection; for debilitated pigs can be combined with injection of camphor caffeine. In order to prevent nitrite poisoning in pigs, green feed for pigs should be fed as much as possible with fresh green feed. Hydrocyanic acid poisoning Generally fresh sorghum seedlings and corn seedlings, flax leaves and linen cakes, squash vines, cassava, almonds and other feeds contain higher cyanogenic glycosides, such as the pigs can easily lead to hydrocyanic acid poisoning after eating. Suffering from a pig, it will show a sudden onset of illness, difficulty in breathing, neck stretching, more than a runny nose, a drop in body temperature, a dilated pupil, a convulsions in the body, and a sudden death in a coma. First aid may be given to poisoned pigs with internal 0.1% to 0.5% potassium permanganate solution 200 ml ~ 500 ml, or internal 10% 10% ferrous sulfate, and then use Meilan injection therapy, that is, 1% Meilan per pig per kilogram A dose of 1 ml was intravenously administered. If the emergency is timely, the symptoms of the pig's poisoning can be alleviated. In order to prevent the occurrence of hydrocyanic acid poisoning in pigs, all feeds containing higher cyanogenic glycosides should be fed in limited quantities. It is best to feed the pigs after drying, fermentation or immersion. Rapeseed cake poisoning After poisoning, pigs will experience frequent urination, coughing, difficulty in breathing, pain in the abdomen, and diarrhea. Blood in the loose stools will cause severe heart weakness, body temperature drop, weakness and death. Can be used 0.5% ~ l% tannic acid or 0.1% ~ 1% tannins to the pig lavage, but also to the pig with oral administration of milk, chicken protein, soy milk and other symptomatic treatment, or injection of 10% sodium plus 5ml ~ 10ml Give heart diuretic. In order to prevent rapeseed cake from being poisoned, the rapeseed cake used for feeding pigs can be crushed and soaked in warm water for 8 hours to 12 hours. The water is removed, followed by boiling for 1 hour with water and stirring frequently. To make most of the toxins evaporate, the rapeseed cake should be properly used with other feeds, and the feeding amount should be gradually increased from as little as possible, and the mouldy rapeseed cake can not be fed to pigs. Gossypol poisoning Pigs fed with fresh cotton leaves and cotton seed must be treated with high temperature (boiled for 1 hour), and the amount fed should not exceed 15% of the concentrate feed, otherwise the pigs may be chronically poisoned. Suffering from the pigs will show symptoms such as mental depression, bowing and bowing, trembling of the body, yellowing of the mucous membranes, shortness of breath, increased body temperature, loss of molars, loss of appetite, increased drinking water, and blood poisoning in the urine. First aid can be used 5% sodium bicarbonate solution to the affected pig gastric lavage or enema, and oral administration of sodium sulfate or magnesium sulfate 25 grams to 50 grams, with intravenous injection of 50% glucose injection 50 ml, to ease poisoning. Solanine poisoning Potato sprouts, fresh stems and leaves, and flower buds contain higher solanine, especially when the potato peels turn green and the tubers germinate. The content of solanine increases significantly when its content reaches More than 0.02% can cause pig poisoning. Suffering from pigs showed loss of appetite, diarrhea, paralysis of the limbs, and convulsions in the body. Severe poisoning caused death in 2 to 3 days. First aid can be used honeysuckle 20 grams, together with alum, licorice each 30 grams, decoction to be warm and add 30 grams of honey, suffering from oral administration of pigs, can be rescued.
