Pig gastric ulcers can cause anorexia, abdominal discomfort, constipation, and diarrhea. How can they be prevented and treated?

    Pig gastric ulcer refers to keratinization, erosion, and necrosis of the gastric mucosa, or autodigestion, forming round ulcer surfaces, and even gastric perforation. Symptoms include anorexia, abdominal discomfort, abnormal intestinal motility leading to constipation or diarrhea, gastric bleeding, and melena. In the early stage of pig gastric ulcer, the stomach shows slight bleeding, and the sick pig only has indigestion, which is not easily noticed. After gastric perforation, acute diffuse peritonitis occurs concurrently, and death can be rapid.

    Treatment principles: eliminate triggering factors, neutralize gastric acid, and protect the gastric mucosa. For pigs with mild symptoms, keep the environment quiet to reduce stress responses, and sedatives may be injected, such as chlorpromazine hydrochloride, 1-3 mg per kg of body weight per dose for pigs; to neutralize gastric acid and prevent damage to the gastric mucosa, aluminum hydroxide, magnesium silicate, magnesium oxide, etc. can be used to reduce the acidity of gastric contents; to protect the ulcer surface, prevent bleeding, and promote healing, bismuth subnitrate 5-10 grams can be administered before feeding, 3 times a day, or tannalbin can be administered, 2-5 grams each time, 2-3 times a day, for 5-7 consecutive days. In addition, to normally empty the chyme, 5-20 grams of sodium polyacrylate can be dissolved in water for drinking each day, or mixed into feed at a ratio of 0.5-5% and fed, for 5-7 consecutive days. If the sick pig is extremely anemic and is confirmed to have gastric perforation or diffuse peritonitis, and has lost value, it should be culled as early as possible.

    Treat according to the cause: 1. Do not grind feed too finely; feed particle size should not be less than 500 microns. 2. Reduce the amount of corn and feed less mash. 3. Add roughage such as grass meal or oat hulls to the feed so that the crude fiber content in the diet reaches 7%. 4. Ensure the content of vitamin E, vitamin B1, and selenium in the feed. 5. When copper is used as a growth promoter, 110*10-6 zinc carbonate should be added to the feed as an additive to counteract copper-induced pig gastric ulcers. 6. Mix sodium polyacrylate into the feed at a concentration of 0.1%-0.2% to change the physical state of the feed so that its retention time in the stomach is normal. 7. Do not frequently move groups, transport, or drive the pigs, and prevent pigs from biting each other. 8. Keep the pig house warm in winter and cool in summer, strengthen ventilation, maintain appropriate stocking density, and leave enough space in the pig house for the pigs to move freely.
