How to prevent and treat porcine nitrite poisoning?

Nitrite poisoning is commonly known as "satiety disease", when pigs eat improperly prepared cabbage, grass, beets, spinach, radish leaves, pumpkin leaves, sweet potato leaves and other green feed, nitrate turns to nitrite and causes poisoning. If the green fodder is stacked for 1 2 days in summer, it will begin to rot; Simmer green fodder over low heat; The green feed after the iron pot is covered and not stirred, and the stewed green feed can cause disease when fed to pigs the next day. The most acute is restlessness, unsteadiness on standing, and sudden death.

After poisoning, he generally manifested dyspnea, foaming at the mouth, frequent vomiting, opening the mouth and sticking out the tongue, cold at the ends of the ears and limbs, pale conjunctiva in the early stage, bluish-purple in the later stage, nervous symptoms such as running and turning in circles, lying on the ground in severe cases, convulsions all over the body, and death from coma and suffocation.

Prevention and control] 1) can not be fed with spoiled and yellowed green feed.

2) Cook green feed to cook, do not cover when cooking, cook and feed.

3) Emetic drugs to induce vomiting, you can choose to use 1% copper sulfate 50 100 ml internally, or choose 1 3 grams of ipecac powder for internal administration.

4) 1% Meilan injection per kilogram of body weight ml, intravenous injection or intramuscular injection, can be repeated after 2 hours of severe disease.

5) 10% glucose 300 ml, vitamin C 20 ml, sodium coffee 5 10 ml mixed intravenous or intraperitoneal injection.

6) 5% toluidine blue injection, milligrams per kilogram of body weight, intravenous injection.

1) Do not feed rotten green fodder.

2) Green fodder should be boiled and fed, do not simmer in the pot overnight. Green fodder is best fed raw, which not only ensures adequate nutrition but also does not cause pig poisoning.

3) Poisoned pigs should cut their ears and tail as soon as possible and bleed.

4) Intravenous or intramuscular injection of 1% Meilan solution, 1 ml per kilogram of body weight; or toluidine blue injection, 5 mg per kilogram of body weight.

All kinds of vegetables contain a large amount of nitrate, when the steaming is not thorough or boiled in the pot without the lid is opened, the temperature is left at 40 60 for too long, resulting in nitrate to be highly toxic nitrite. If the vegetables are piled up for too long and spoiled, the nitrate can also be reduced to nitrite under the action of bacteria. Pigs will quickly become ill and die if they eat this green fodder.

Clinical symptoms] 10 30 minutes after the pig eats the sudden onset, manifested mania, vomiting and salivation, dyspnea, rapid heartbeat, walking swaying, rambling, whole body tremor, turning in circles. The mucous membranes and abdomen are gray-white at the beginning, and then turn purple, the limbs and ears are cold, the body temperature drops, falls to the ground and spasms, foams at the mouth, and dies soon if not rescued in time. 【Pathological changes】White pig** pale or blue-gray, the blood is purple-black, such as soy sauce, and the coagulation is poor.

A slightly longer course of the disease may show congestion and bleeding in the mucosa of the stomach, pylorus, and duodenum. 【Prevention and control measures】(1) Green fodder should be fed fresh, not steamed. When it must be steamed, it should be boiled quickly and the lid should be removed, and it should not be simmered in the pot overnight.

Do not pile up green fodder, if you can't eat it for a while, you can spread it out or hang it overhead.

2)** can be used with 1% Meilan solution, intravenous or intraperitoneal injection at 1 ml per kilogram of body weight (for piglets). It can also be given intravenously with 5% dextrose or dextrose saline. Oral or injectable large doses of vitamin C are also effective.

Good afternoon 1

Bloodletting: Pigs with serious poisoning should be rescued as soon as possible by cutting the tips of the ears and tails with scissors, and the amount of bloodletting is 1 ml kg of body weight. Performed with medication as soon as possible after phlebotomy**.

2. After poisoning, use 1% Meilan solution for intravenous injection in time, and the dosage is 1 mg 2 mg kg body weight.

or intravenous injection of 5% toluidine blue solution with a faster and better effect, at a dosage of 5 mg kg of body weight (can also be injected intramuscularly and intraperitoneally).

FYI. I wish you a happy and happy life.

Answer: Use emetic agent to induce vomiting to eliminate residual poisons, and pay attention to the care and heat preservation of sick pigs. After gastric lavage with potassium permanganate solution, salt laxatives or milk, egg whites, etc. are taken internally. Immediately cut off the ears, cut off the tail and bleed, and then poured cold water all over the body to drive away the movement.

Detoxification. 1% Melan solution (1 gram of Melin, 10 ml of alcohol, 90 ml of saline), 1 ml per kilogram of body weight, intramuscular injection or intravenous injection. In order to reduce methemoglobin to hemoglobin, vitamin C can be used, combined with melan, glucose, etc.

Depending on the condition, fluids, oxygen, and respiratory stimulants can be injected.

Question: What method is used for individual free-range breeding without equipment.

For example, where to cut the ears and what to cut them into. Its tail is only two inches long, and the first aid should be carried out on the tip of the ear and tail tip of the pig as soon as possible, and immediately injected intravenously or intramuscularly with 1% Meilan solution (1 ml per kilogram of body weight of pigs), or intravenous injection of toluidine blue solution (5 ml per kilogram of body weight of pigs), and cooperated to give oral or injection of high-dose vitamin C and intravenous injection of glucose injection solution to the affected pig; For pigs with weak hearts, camphor caffeine can be injected together.

Ask what to use to induce vomiting.

What to use to induce vomiting.

Green fodder poisoning.

Causes: Nitrates are found in green fodder such as cabbage, turnip leaves, beets, and wild amaranth. Some farmers are accustomed to putting cabbage and other green fodder in a pot to simmer overnight, and the next day to feed pigs, often poisoning and death of pigs.

In addition, feeding pigs with green fodder such as rotten cabbage and beet leaves that have been stacked for a long time also causes poisoning. Pigs suddenly became ill soon after eating, irritable, foaming at the mouth, sometimes vomiting, turning in circles, and in more serious cases, they could not stand after falling; normal or slightly low body temperature, cold ears; The mucous membranes and ** are initially grayish-white, then turn bluish-purple. This is caused by the collapse of nitrite at 40-60°C after 6-8 hours of bacterial action to become highly toxic.

Suggestion: Cabbage and other green fodder are fed raw, and when the green fodder with bad taste must be cooked, it should be cooled immediately after boiling through the fire, and then put it in the tank, and it must not be left in the pot overnight. Immediately cut the tips of the ears and tails of the poisoned pigs and bleed; Those with mild poisoning can be filled with 5-10 egg whites, kilograms of soy milk or Weimin milk; 50-100 grams of mung beans and 50 grams of licorice can be decocted; Intraperitoneal injection with dextrose saline 500-1,000 ml.

Store in a dry place to prevent mold and deterioration, and do not use too many additives.

Green fodder moisture, pure orange is more prone to mold, rot, must be properly preserved, it is best to pick and feed, try not to store for a long time, if stored, drying, cooking is also a way, of course, if there is a condition to do the song, put it in the cold storage can also. Sakura Zen.

Clinical symptoms: trembling and spasms, weakness of the hindquarters, unsteadiness or immobility, dyspnea, mouth opening and tongue sticking out, foaming at the mouth, salivation and vomiting, abdominal pain and restlessness, diarrhea, drop in body temperature, cold limbs, ears and nose. The mucous membranes are pale in the early stage, cyanosis in the later stage, ** bruising, and death is mostly within 1 to 2 hours.

**:( 1) Use emetics to induce vomiting internally to eliminate residual poisons, and pay attention to the care and heat preservation of sick pigs. (Qi Bizhen 2) After gastric lavage with potassium permanganate solution, take salt laxatives or milk, egg whites, etc. internally.

3) Immediately cut off the ears, cut off the tail and bleed, and then pour cold water on the whole body to drive away the exercise. (4) Detoxification: 1% Meilan solution (1 gram of Meilan, 10 ml of alcohol, 90 ml of normal saline), 1 ml per kilogram of body weight, intramuscular or intravenous injection.

5) In order to reduce methemoglobin to hemoglobin, vitamin C can be used with the application of melan, glucose, etc. (6) According to the condition, infusion, oxygen infusion, injection of respiratory stimulants, etc. Prevention:

When using cabbage, beets, radishes and other melon vegetables to make pig feed, it is best to feed them fresh, such as when it must be cooked high and coarse, the lid of the pot should be opened and the pot should be added to the full fire, boil quickly, stir constantly, and do not stuff in the pot overnight. When storing greens, etc., they should be spread out and stored, and should not be piled up, so as to avoid the production of nitrite. _

Induce vomiting. It is generally used for organophosphate and other pesticide poisoning. The emetic agent gram of veratroline can be injected subcutaneously, or 1 2 grams of potassium antimony tartrate can be taken orally. If there is no emetic, wooden sticks and hoses can also be used to lightly touch the throat mucosa of sick pigs to cause them to vomit.

2.Wash. Gastric lavage. If the poison has entered the pig for 4 to 6 hours, gastric lavage should be performed. For hydrocyanic acid poisoning, 1% potassium permanganate solution or 3% hydrogen peroxide can be used; For organophosphorus pesticide poisoning, 1% 5% sodium bicarbonate solution can be used; For zinc phosphide poisoning, 1% copper sulfate solution can be used.

Gastric lavage is repeated until the water cleared. Gastric lavage should not be used for corrosive drug poisoning, so as not to cause gastric perforation. 3.

Diarrhea. If the poison has entered the intestines, laxatives should be given. Generally, salt laxatives should be used, and commonly used salt laxatives are miscanthus nitrate, magnesium sulfate, etc. When salt poisoning occurs in pigs, salt laxatives can not be used, and a large amount of water should be administered.

4.Use. with an antidote. If the poison enters the bloodstream, none of the above detoxification methods will be effective, and an antidote must be used. For nitrite poisoning, 1% melanin solution can be used, 1 ml per kilogram of body weight, intramuscularly or intravenously; For hydrocyanic acid poisoning, 1% sodium nitrite solution can be used intravenously at 1 mL/kg body weight; For organophosphate pesticide poisoning, atropine or pralidoxime can be injected; Alkaline poisoning can be neutralized and detoxified with dilute hydrochloric acid or vinegar; Alkaloid poisoning can be detoxified with potassium permanganate solution.

5.Put. Bloodletting. If the poisoning has been prolonged and the poison has entered the bloodstream in large quantities, the antidote can be used at the same time as the method of venous bloodletting, and the amount of each bloodletting is 300 400 ml. In addition, the use of infusion, giving a large amount of water and other methods to promote urination and sweating, can also alleviate the symptoms of poisoning.
