What are the causes of pigs grinding their teeth at night and what prevention and treatment methods are there?
Pigs grinding their teeth at night has causes in many aspects, and corresponding measures should be taken to eliminate it.
Single feed type
It is best to feed pigs compound feed, because the various nutrients in compound feed, such as minerals and trace elements, are reasonably balanced. When feeding concentrated feed, it should be paired with green and roughage, and an appropriate amount of minerals and trace elements should be added, 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 each day for each pig supplement the feed with 30-50 grams of bone meal or eggshell powder or calcium bicarbonate powder, and 6-19 grams of salt, fed 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 stimulated, and various methods can be used. For example, for pigs weighing more than 10 kg, use 10 tablets of rhubarb soda tablets with a content of 0.3 grams, grind them into powder and mix into the feed for feeding, 2 times a day, fed continuously for 3 days, which can play a role in strengthening the stomach. If at the same time use 50 grams each of hawthorn, malt, and medicated leaven (amount for 1 dose), decoct the juice and mix into the feed for feeding, 2 times a day, fed continuously for 5 days, it can also help digest food. You can also 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 and mix into the feed for feeding. You can also feed each pig 100-200 grams of purslane, 150-200 grams of carrot, and 50-100 grams of Atractylodes lancea each day; or 25 grams each of Atractylodes lancea, pine needles, and Platycladus orientalis leaves, sun-dried, crushed into powder, and mixed into the feed for feeding. Or use 50 grams of costus root, 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 taking two doses continuously is sufficient.
Parasite infestation
When pigs have parasites in their bodies, nighttime teeth grinding can also occur, and they must be eliminated promptly. Deworming pigs is generally carried out on sunny days under the premise that the pigs have no other diseases, with feeding stopped at noon, and when the pigs are on an empty stomach at eight or nine in the evening, according to the pig's body weight, use 15-20 mg per kg of albendazole or levamisole, anthelmintic or tetramisole, grind them, mix into a small amount of concentrated feed, and administer in one feeding. Two days after feeding, dissolve 1 kg of quicklime in 5 kg of water, take the clear limewater solution, continue to mix into the feed for feeding, once a day, fed continuously for 2 days, and the parasites in the pig's body 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, intramuscular injection of 0.1 ml per kg of body weight, and feed compound vitamin B, 2 times a day, 20 tablets each time, used continuously for one week.
