Prevention and treatment of common pig gastric ulcer in large-scale pig farm

Pig gastric ulcer is one of the most common diseases in pigs, and it is also common in large-scale pig farms. Most of the diseased pigs were found to die from acute gastric bleeding caused by gastric ulcers. This disease is a kind of gastropathy characterized by localized ulcer of stomach and esophagus in pigs. The incidence varies greatly, ranging from about 2% to 5% and as high as 15% to 25%. Most of them occur in fast-growing pigs aged from 3 months to 8 months.

The etiology of the disease is still inconclusive. Primary gastric ulcer may be related to feed quality, feeding management, environmental hygiene and other factors. Secondary gastric ulcers can be seen in catarrhal ulcers caused by acute and chronic gastric catarrhal processes and inflammatory ulcers caused by gastrointestinal inflammation. The cases of gastric ulcer caused by fungal infection in pigs are high, especially in piglets, and there are often infectious diseases and parasitic diseases such as blood spear nematode disease, mucous membrane disease, foot-and-mouth disease, blister disease, acne disease, pig dentate stomach worm and so on.

Clinical symptoms of this disease usually have no obvious clinical symptoms, it is not easy to find before death, except for acute death, it is generally found during slaughtering. It can occur in pigs of any age, but shelf pigs are common. Some sick pigs show indigestion, and sometimes show depression, anorexia, weakness, vomiting, abdominal pain, and even visible mucous membrane is obviously pale, anemia, feces are black paste. Some healthy pigs may die suddenly because of internal bleeding after exercise or excitement. The body is extremely pale and extensive bleeding in the stomach can be seen by autopsy. In most cases, gastrointestinal erosion and ulcers can be seen only during postmortem examination or slaughter.

It is difficult to diagnose this disease before death. According to the black stool, pale body showed bloody anemia; acute death, autopsy can be seen gastric mucosal bleeding, erosion, necrosis and ulcer, can make a diagnosis.
