Identification method Judging by age: 1 to 2 days old diarrhea: mostly caused by Escherichia coli, hypoglycemia and Clostridium; diarrhea after 7 days of age: infectious gastroenteritis, dysentery, salmonella, rotavirus; 10 days old All kinds of ages above, acute and severe watery diarrhea: caused by infectious gastroenteritis, epidemic diarrhea, pseudorabies; pigs of all ages, no obvious time, generally less severe diarrhea: caused by Escherichia coli and rotavirus A small number of pig diarrhea in one litter, and the largest and most robust pig diarrhea in the individual: mostly caused by Clostridium enteritis; a small number of pig diarrhea in one litter, and the smallest and weakest pig diarrhea in the individual: mostly caused by hypoglycemia. According to the degree of diarrhea: if it is fulminant, rapidly spreading diarrhea, it is viral diarrhea; if it is recessive, slow spreading, and worsening over time, it is bacterial or parasitic diarrhea. According to the pH and traits of feces: the feces of viral diarrhea are mostly acidic, and the feces of other diarrhea are mostly alkaline; the watery sample is spray-like diarrhea mostly caused by virus, sticky or mushy, with foamy feces Most of them are caused by bacteria; the mushy, yellow-gray, and foul-smelling feces are mostly coccidiform diarrhea; the fecal odor is mostly infectious gastroenteritis; the diarrhea is accompanied by oral foam, vomiting, and most of the neurological symptoms are caused by pseudorabies virus. Judging by whether there is blood in the feces: The black tar-like feces are mostly gastric ulcers, which may be related to the powder being too fine; the reddish feces are mostly blood stasis and whipworms (the end of one end is small, about 2 cm, and the insects are dewormed with fentanyl). Cause classification Bacterial diarrhea: Escherichia coli, Clostridium perfringens enteritis, Shigella dysenteriae, L. solani. Viral diarrhea: infectious gastroenteritis, epidemic diarrhea, rotavirus, pig pseudorabies virus. Parasitic diarrhea: aphids, coccidia, whipworms, colonic pouch ciliates. Non-infectious factors: temperature, hypoglycemia (hunger diarrhea), dietary antigen allergic diarrhea (soybean allergy), non-pathogenic white diarrhea (iron deficiency diarrhea, enzymes and gastric acid deficiency sputum). Prevention and control method Precautionary measures Strict bio-safety measures are implemented. According to the disinfection principle of “one sweep, two flushes, three eliminations, and four empty columnsâ€, we must continue to work on disinfection and immunization, and make E. coli immunization in 45 days and 15 days before sows. Immunization against infectious gastroenteritis and epidemic diarrhea was made 30 days before birth. Do a good job of insulation and strengthen feeding management. Principles of treatment: identification of causes, removal of gastrointestinal (half-starvation therapy), enhancement of resistance, antimicrobial (antibacterial, antiviral and antiparasitic) 1, drinking water. Supply adequate and clean drinking water. Oral rehydration salt formula (viral diarrhea is especially needed): 2.5 g of salt, 3.5 g of sodium bicarbonate, 1.5 g of potassium chloride, 20 g of glucose, and water to 1000 ml. 2, thorough disinfection. Apply a conventional disinfectant to the sow's abdomen, breast, hindquarters or add to drinking water. Once the diarrhea is found to be removed immediately, disinfect with a disinfecting mop 3, not severe diarrhea. Half-stop non-stop water, oral rhubarb soda tablets (0.5 ~ 1 piece / head) or sputum charcoal silver (0.5 ~ 1 piece / head), add 1% anti-diarrhea first aid kit in the feed, use 3-7 days to heal . 4, viral diarrhea (severe diarrhea). Intraperitoneal injection of 5% glucose normal saline 50 ~ 100 ml + 5% sodium bicarbonate 10 ~ 20 ml + inosine 2 ml + interferon, or 5% glucose normal saline 500 ml + 5% sodium bicarbonate 10 ~ 20 ml + ground 10 to 20 mg of rice + antiviral drugs, 50 ml per pig, intraperitoneal injection.
