Why do pigs grind their teeth at night?
First, the feed is single, it is best to feed the pig with nutritious compound feed at full price. Concentrate feed should be matched with green roughage, and appropriate amount of minerals and trace elements should be added. Adding 1%-2% mineral feed to pig diet, such as bone meal, calcium hydrogen phosphate, eggshell powder, etc., and adding 0.25%-0.5% salt, etc., has a certain effect on preventing pig tooth grinding at night. The phenomenon of tooth grinding at night can be eliminated by supplying bone meal or eggshell powder, calcium bicarbonate powder 30g to 50g and salt 6g to 19g in the feed of each pig every day for 7 days.
Second, dyspepsia for pigs with dyspepsia to strengthen the stomach, a variety of methods can be used. For example, for pigs weighing more than 10 kg, 10 pieces of rhubarb soda tablets with a content of 0.3 grams, fed with the final mixture, twice a day for 3 days, can play a role in strengthening the stomach. If you use 20 grams of Atractylodes macrocephala Koidz, 30 grams of Poria cocos, 30 grams of tangerine peel, 10 grams of gold in chicken, 30 grams of malt, 10 grams of licorice, and feed with juice after frying. Feeding twice a day for 5 days can also play the role of digestion.
Third, when parasites harm pigs with parasites, the phenomenon of grinding teeth at night will also occur and must be removed in time. Deworming pigs is generally carried out on the premise that pigs have no other diseases, stop eating at noon, and when pigs are fasting at 8: 9 p.m., albendazole or levamisole, anti-vermicidal or repellent net each 15 mg per kilogram of body weight, grind, mix into a small amount of concentrate, a feeding. Two days after feeding, dissolve 1 kg of quicklime in 5 kg of water, take its supernatant, continue to mix and feed, once a day for 2 days, the parasites in the pig can be expelled.
Vitamin deficiency pig molars caused by lack of vitamins (especially vitamin D) can be injected intramuscularly with vitamin AD injection at 0.1 ml per kilogram of body weight and fed with compound vitamin B twice a day, 20 tablets each time for 7 days.

Breeding of introduced Pig breeds and Application of New breeding techniques
The continuous development and progress of science and technology make it possible for people to explore the laws of nature and reveal biodiversity. The greatest progress of pig breeding in the 20th century is that the daily gain of pigs exceeded 800g / day, the lean meat rate reached more than 60%, the ratio of feed to meat reached 2.8g / ∶ 1, and the body weight of pigs reached more than 90kg in 156days. In recent years, with the continuous development of breeding theory and practice, pig breeding in developed countries has gradually changed from breed selection to specialized breeding.

Diagnosis and treatment of Porcine Neurological symptom Blight
Pig raising often encounters the occurrence of pig disease with "dyspnea" as the main symptom. There are 6 kinds of epidemic diseases that show "dyspnea" symptoms, which are easy to be confused in clinic, resulting in misdiagnosis. Especially for pig farms, households or rural veterinarians who lack laboratory conditions, clinical differential diagnosis is particularly important. 1. The pathogen of swine edema disease is septic Escherichia coli. It is easy to occur under stress conditions such as temperature change, weaning and refeeding, and most of them are pigs that eat more and grow faster than those who eat more than 20kg of 30kg after weaning. Sick pigs show low body temperature, agitation, walking blindly and turning in circles.
