What about nitrite poisoning in pigs?

Pork can be said to be an indispensable meat product in China, and the area of raising pigs in our country is also very large. When raising pigs, the management is very important, especially the feed management, if the feed is improper, it can easily lead to nitrite poisoning and other adverse phenomena in pigs, seriously affecting the growth of pigs. So what should we do about pig nitrite poisoning? What are the symptoms? Let's take a look at it with the editor.

1. Etiology

The content of nitrate in all kinds of green feed and root feed such as cabbage, radish and potato is very rich. When we plant, the herbicides, nitric acid and other substances we use will increase the content of nitrate in these vegetables. When the temperature and humidity are suitable, the reducing bacteria will multiply in large numbers. Then when the vegetables are cooked or withered and die, the reducing bacteria will reduce the nitrate to nitrite, causing poisoning to the target. If pigs eat, it will lead to disorders of gastrointestinal function in pigs, lead to parasites, reduce the concentration of gastric acid, and cause pig poisoning.

2. Symptoms

Porcine nitrite poisoning can be divided into acute and chronic onset time. In the case of acute poisoning, the sick pig can get sick about a quarter of an hour after eating, and it only takes about five hours if it is chronic. Usually, pigs with strong growth ability and high food intake will become seriously ill because they eat too much. Sick pigs in the onset of increased breathing, increased urination, mucosal cyanosis can be seen with the naked eye, and will leave black-red blood, low body temperature. There are mainly symptoms of gastroenteritis, such as drooling, vomiting, diarrhea and so on. In serious cases, the corner bow is dilated, and the death is pulled out in the end.

3. Prevention and control methods

Strengthen prevention

First of all, of course, it is necessary to strengthen the prevention work. When feeding green feed, it is best to carry out raw feeding. For mildew deterioration, accumulation and decay of feeding should be dealt with in time, not feeding. Do not stack the feed together or cook it. If you need to cook it under special circumstances, cook it as soon as possible, put it in a pot and stir it while cooking. Absolutely not to spend the night, overnight ripe green feed should be thrown away. Then put an appropriate amount of vinegar into the feed when cooking, which can not only achieve the purpose of sterilization, but also decompose nitrite. Finally, the application of nitrate fertilizer should be stopped before harvest and green feeding.

Timely treatment

After the onset of the disease, toluidine blue and other specific drugs should be used to interpret pigs in time. According to the body weight of pigs, the injection volume should be controlled reasonably, and the injection methods can be mainly intravenous injection, intramuscular injection and so on. Toluidine blue is about 5 mg / kg. In the use of antidote, in conjunction with hypertonic glucose and other use, the dose is controlled at about 400 ml. When the sick pigs are short of breath, Nikethamide and other drugs are used and about 0.5 ml of epinephrine hydrochloride is injected to stabilize the breathing of the sick pigs.
