What are the prevention and treatment methods for pig overeating disorder?

Irregular feeding, uneven hunger and fullness, and other stress responses are triggers; if the feed is moldy, it can be complicated by nitrite poisoning.

Prevention and treatment measures: strengthen feeding management, feed according to the pig's requirements, and provide balanced feed. Prevent pigs from overeating; the feeding amount should be appropriate to maintain their basic and growth needs; the feed formula should be reasonable and stable to prevent sudden changes. When it is necessary to change the feed variety, a 3-5 day transition period is required. During feed changes or sudden weather changes, anti-stress drugs such as electrolyte multivitamins, vitamin C, and glucose powder can be added to the pigs' drinking water. When pigs weigh more than 75 kg, 0.3% salt should be added to their feed, feeding should be stopped for 1 meal within 1 week, and the pigs' water intake should be increased. The pigs' drinking water should be kept clean and hygienic, and the height of the free-access drinker should be adjusted as the pigs grow, preferably 15-20 cm above the pigs' backs. Feeding moldy and spoiled feed is prohibited.

In treatment, the principle is to empty the accumulated food in the stomach and restore stomach function. Pigs can be fasted for 1 day and given a small amount of water. To promote stomach movement function and emptying of contents, abdominal massage can be performed, and steady driving exercise can also be done. Seriously ill pigs must be handled carefully to prevent gastric rupture.

For pigs that have already developed the disease, Bimekelin (bethanechol chloride injection) can be injected, 10 mL per 50 kg of body weight, twice a day. For pigs with protruding and hardened nictitating membranes, scissors can be used to cut off the hardened nictitating membrane and let it bleed. To prevent fermentation of stomach contents, 1-5 g of ichthammol and 10-15 mL of ethanol can be added with an appropriate amount of water and administered by gavage at one time, or 20-50 mL of vinegar can be administered by gavage at one time.
