What causes pigs to grind their teeth at night

There are many reasons why pigs grind their teeth at night, and corresponding measures should be taken to eliminate it.

Single feed: it is best to feed pigs compound feed, because the various nutritional components of compound feed, such as minerals and trace elements, are reasonably matched. When feeding concentrated feed, it should be paired with green and roughage, and minerals and trace elements should be added in appropriate amounts, such as adding 1%-2% mineral feed to the daily ration, such as bone meal, calcium hydrogen phosphate, eggshell powder, etc., and adding 0.25%-0.5% salt, etc., which has a certain effect on preventing pigs from grinding their teeth at night. Or supply each pig daily with 30-50 grams of bone meal, eggshell powder, or calcium bicarbonate powder and 6-19 grams of salt mixed into the feed, continuously for 7-10 days, and the nighttime teeth grinding phenomenon can be eliminated.

Digestive disorders: chronic indigestion in pigs can also cause nighttime teeth grinding. For pigs with indigestion, the stomach should be strengthened and appetite promoted, and various methods can be used. For example, for pigs weighing more than 10 kg, use 10 tablets of rhubarb soda tablets containing 0.3 grams, grind them into powder and mix into the feed, feed twice a day for 3 consecutive days, which can help strengthen the stomach. If at the same time 50 grams each of hawthorn, malt, and medicated leaven (one-time dosage) are decocted and the juice is mixed into the feed, fed twice a day for 5 consecutive days, it can also help promote digestion. Alternatively, take 20 grams of Atractylodes macrocephala, 30 grams of Poria cocos, 30 grams of dried tangerine peel, 10 grams of chicken gizzard lining, 30 grams of malt, and 10 grams of licorice, decoct and take the juice to mix into the feed. Each pig can also be fed 100-200 grams of purslane, 150-200 grams of carrot, and 50-100 grams of Atractylodes lancea daily; or 25 grams each of Atractylodes lancea, pine needles, and arborvitae leaves, dried in the sun, crushed into powder, and mixed into the feed. Or use 50 grams of costustoot, 60 grams each of dried tangerine peel, magnolia bark, and bitter orange, 40 grams of hawthorn, 90 grams each of malt and radish seed, 40 grams of Atractylodes macrocephala, and 35 grams each of angelica, astragalus, and licorice, decoct the juice; each dose is taken for 2 days, and two consecutive doses are enough.

Parasite infestation: when pigs have parasites in their bodies, nighttime teeth grinding can also occur, and they must be eliminated in time. Deworming pigs is generally carried out on a sunny day on the premise that the pigs have no other diseases. Feeding is stopped at noon, and at 8 or 9 p.m. when the pigs are empty, according to the pig's body weight, use 15-20 mg per kg of albendazole or levamisole, dichlorvos, or tetramisole, grind it, mix it into a small amount of concentrated feed, and feed it all at once. Two days after feeding, dissolve 1 kg of quicklime in 5 kg of water, take the clear limewater liquid, and continue mixing it into the feed, feeding once a day for 2 consecutive days, and the parasites in the pigs' bodies can be eliminated.

Vitamin deficiency: for pig teeth grinding caused by a deficiency of vitamins in the body (especially vitamin D), use vitamin AD injection, inject 0.1 ml intramuscularly per kg of body weight, and feed compound vitamin B, twice a day, 20 tablets each time, for one consecutive week.
