In summer, when the temperature rises, the potatoes that the people stored also began to germinate, and some were reluctant to discard and feed the pigs. Pigs ingest large amounts of germinating, rotted potato tuber roots, and are characterized by hemorrhagic gastroenteritis and nerve damage.
First, the poisoning mechanism
Potatoes contain biosaponin (Solacia nigrum), nitrate (up to 4.7%) in stems and leaves, and decayed roots of spoilage. When the potato was stored for too long, germinated and rotted, the solanine and nitrate content increased significantly. Solanine is absorbed mainly in the gastrointestinal tract, and absorption is accelerated when the mucous membranes are damaged, which can stimulate the gastrointestinal mucosa and cause gastroenteritis. Absorbed into the blood to cause red blood cell lysis. Acting on the central nervous system causes sensory and motor nerve palsy.
Second, the clinical symptoms
Mainly manifested as neurological symptoms and digestive disorders. At the beginning of the illness, he was uneasy, squawking, and chaotic. Afterwards, he was mentally depressed, he had a strong back, and wobbled when he walked. The gait was unstable. Severe cases had dyspnea, conjunctival cyanosis, paralysis of limbs, and movement disorders, such as unresponsive rescue, rapid heart failure, convulsions, paralysis and death. Mild cases, mainly gastrointestinal changes, runny nose, vomiting and diarrhea, later showed watery diarrhea, mixed with mucus and blood, fecal odor, intestinal swelling, abdominal pain. The sick pigs were depressed, with drowsy heads, reduced appetite or obsolescence, edema on the face of the head and neck and eyes, visible blisters, and a purple rash on the abdomen. Severe skin purplish, body temperature dropped below 37 degrees, extremely exhausted.
Third, prevention and treatment
Immediately feed the potatoes and change the feed. Take hunger therapy, fasting for 2-3 days to promote toxin excretion, can be irrigated with 1% cupric sulfate to induce vomiting, and use vegetable oil or salt laxatives to cleanse the gastrointestinal tract. Intravenous injection of 300-500 ml of 5% glucose saline solution, 5-10 ml of sodium sulfate, 5-10 ml of vitamin C1O, once daily for 3 days, to protect the liver and detoxify, maintain liver function and cardiac diuresis.
In order to prevent secondary infections, pigs with severe diarrhea were given antibiotics in a prophylactic amount and care was taken at the same time.
When storing potatoes, keep them in a cool, dry place to prevent germination. It is best not to feed the pigs that have germinated, rotted, or turned green. The last resort is to remove the rotten parts and peel them, soak them thoroughly, or soak them thoroughly to make the toxins destroyed. Then go to the soup and feed them.
