What are the symptoms of gastric ulcers in pigs? An analysis of gastric ulcer symptoms in pigs!
Affected pigs show anorexia, abdominal discomfort, and abnormal intestinal motility, leading to constipation or diarrhea, gastric bleeding, and melena. In the early stage, there is slight gastric bleeding with indigestion, which is often difficult to detect. Once the stomach perforates and acute diffuse peritonitis develops, death can occur rapidly. According to the degree of onset, it can be divided into occult, chronic, and acute.
　　
Occult. There are no obvious symptoms, and growth rate and feed conversion rate are almost unaffected; it is only discovered after slaughter.
  　　
⟧ Acute. When this disease occurs acutely, affected pigs may die suddenly due to massive bleeding from the ulcer; some affected pigs suddenly vomit blood during intense exercise, biting each other, or around farrowing, pass coal tar-like bloody stool, have decreased body temperature, rapid breathing, abdominal pain and restlessness, pale skin and mucous membranes, and a weak constitution, ultimately dying from exhaustion. When affected pigs develop peritonitis due to gastric perforation, they generally die within 1 to 2 days after symptoms appear.
　　
Chronic. Appetite is reduced or the pig stops eating, the skin and visible mucous membranes of affected pigs are obviously pale, and there is occasional vomiting of blood or blood in vomit, arched back or lying prone, and a tendency to lie down because of weakness, with progressive emaciation. Constipation occurs at first, then changes to coal tar-like feces, and the occult blood test is positive. The condition sometimes worsens and sometimes improves, causing digestive disturbances and abdominal pain. A few cases have symptoms of chronic peritonitis. The disease course is 7 to 30 days.
