Why do pigs often vomit? What should I do?

Recently, breeding friends asked me that the pig spirit is good, the food is normal, is often vomiting, what is the reason, how to treat and control. In fact, this is mainly caused by gastric ulcers in individual pigs. There are several reasons for gastric ulcer.

(1) Primary gastric ulcer: mainly mildew of feed, poor quality of raw materials, fine crushing of sow feed, especially lack of unsaturated fatty acids and vitamin E, vitamin B and selenium in feed. Feeding irregular hunger and satiety uneven cause digestive system dysfunction, induce gastric ulcer.

(2) Secondary gastric ulcer: mostly due to classical swine fever, erysipelas, Angiostrongylus rubrum, copper poisoning caused by gastric congestion, bleeding, erosion and ulcers.

[diagnostic points:]

(1) the pig is in good spirits, vomiting, vomiting yellow undigested feed, vomiting before eating.

(2) abdominal pain, restlessness, molars, periodic anorexia, black stool, and occasional diarrhea.

(3) when there is gastric bleeding and ulceration, the body surface is pale, loss of appetite, occasional hematemesis, dry stool and low body temperature.

(4) autopsy

Acute type: gastric bleeding, gastric dilatation, blood clots in the stomach.

Subacute: there are a large number of yellowish-brown contents in the stomach, mostly watery, the contents have the smell of fermentation, rinse with clean water, pyloric area and gastric fundus wrinkles scattered with erosion spots, and there are well-defined ulcer lesions.

[prevention and control methods:]

(1) to reduce pain and prevent the development of ulcers, chlorpromazine hydrochloride or astragalus polysaccharides + penicillin can be injected intramuscularly to reduce inflammation.

(2) neutralize gastric acid: magnesium aluminum silicate hydroxide increases the PH value of stomach contents, while oral tannic acid protects the stomach, or 0.2% baking soda can be added to feed to neutralize stomach acid.

(3) for severe bleeding cases, calcium gluconate + vitamin C was injected intravenously and vitamin K was added to feed or diet.

(4) usually pay attention to whether the feed is moldy, wash the trough in time; ensure that the feed nutrition is comprehensive, crush particles moderate, not less than 3.5mm; pay attention to pig health care, prevent classical swine fever, swine erysipelas, feed phased addition of Huanglian jiedu powder + amoxicillin + cod liver oil, improve immunity, repair gastrointestinal mucosa, reduce the incidence of gastric ulcer.
