Description

Technical Field

[0001] The invention belongs to the technical field of veterinary drugs, and particularly relates to a traditional Chinese medicine composition for preventing and treating piglet diarrhea and a preparation method thereof. Background Art

[0002] It is reported that piglet diarrhea is a major problem in the pig farming industry, and the subsequent piglet mortality rate is as high as over 25%. In particular, the incidence of newborn piglet diarrhea is difficult to reduce, which has a serious impact on the pig farming industry. Piglet diarrhea can occur all year round, especially in spring and winter. There are many causes of piglet diarrhea, such as poor insulation in the pig house when it is cold, damp and unventilated pig houses, inadequate disinfection, indigestion of food, vertical transmission from sows, bacterial and viral infections, and piglet stress and feed mold. The hazards of piglet diarrhea include increased piglet mortality, reduced piglet immunity, prolonged market time, and increased feeding costs.

[0003] According to the basic theory of Chinese veterinary medicine, diarrhea caused by cold in piglets is watery, thin, cold, painful and borborygmus in the abdomen. Piglets like warmth and hate cold. If diarrhea is not treated and the course of the disease is prolonged, the stool is loose and yellowish brown, and the stool is foul-smelling, which is mostly a sign of damp heat. Loose stool, undigested food, and foul smell are mostly signs of food injury. After eating, the stomach is stuffy and uncomfortable, the complexion is earthy, and the depression is tired and weak. Most of them are diseases in the spleen. Diarrhea at five o'clock, undigested food, cold pain in the lower abdomen, and cold limbs are mostly diseases in the kidney. The body temperature rises, the spirit is depressed, vomiting is accompanied by dehydration, the feces are fishy and watery and mostly yellow, undigested food, diarrhea is like a flood and is in the shape of a jet, the body is thin, and the person is afraid of the cold and curled up or huddled together, which is mostly bacterial and viral diarrhea.

[0004] At present, antibiotics are mostly used in clinical prevention and treatment of piglet diarrhea, but the drug residues and drug resistance of antibiotics, coupled with long-term and large-scale use, will definitely affect the normal intestinal microbial flora of the body, and may cause adverse reactions such as intestinal dysfunction. With the advent of the era of reducing antibiotics, reducing antibiotics and replacing them is the best strategy. Therefore, we must give full play to the unique advantages of traditional Chinese medicine and its role in clinical prevention and treatment of piglet diarrhea. Summary of the invention
