Every year in the winter and spring alternate seasons, the epidemic situation of piglets' diarrhea is prone to occur. The current epidemic of new born piglet diarrhea has spread throughout the country. Judging from the situation in the pig farms, most of them belong to the virus, but the harm of E. coli is also present. Even in some pig farms, it is the main cause of diarrhea. This article summarizes.
Pathogenicity E. coli is a generic term for a large group of gram-negative bacilli that are present in the gastrointestinal tract. Some can produce one or more enterotoxins and become pathogens. The serotypes of pathogenic E. coli are complex, but they can be roughly divided into diarrhea-type E. coli and pig edema-type E. coli. Diarrhoea-producing E. coli first adheres to the wall of the small intestine and then releases toxins, causing the small intestine not only to absorb water and electrolytes, but also to secrete large amounts of water and salt, resulting in diarrhea.
The epidemic features are mainly seen in the piglets from a few hours to 5 days after birth. They are more common in 1st to 3rd day of age. They can develop after 12 hours of birth. Generally, one piglet begins to infect other piglets first, and the highest incidence rate is. Up to 100%, the mortality rate is also high. There is a certain relationship between the severity of jaundice and the parity of sows, that is, the highest incidence of sows in the first child, the mortality rate is also high. Contaminated sows are the source of infection. The introduction of breeding pigs from off-site brings the disease into the market, and the growth of the piglets caused by the retained piglets. The bacteria are mainly excreted by the contaminated pig manure and contaminated the ground feed trough. By contaminating the sow's nipples and skin, the piglets eat pathogens and eat them into the gastrointestinal tract after birth. Xia piglets contaminate the pig farm environment through excrement of pathogenic bacteria in the faeces and pass it to other pigs.
The main symptoms of clinical symptoms and necropsy lesions are pulling yellow peony. Most of the feces show yellow water samples, with bubbles and inclusions of curd debris. When the squat is heavy, the sow of the sow's cunt can appear red, the hind limb is contaminated with faecal fluid, the sick pig is depressed, does not feed on milk, and is dehydrated. The two eyes collapse and die in a coma. An autopsy showed acute catarrhal inflammation in the small intestine, swelling of the intestinal mucosa, congestion, and bleeding. The wall of the intestine becomes thin and loose. Swelling and swelling of the gastric mucosa. The mesenteric lymph nodes are swollen and the cut surface is juicy.
Classification of diseases Piglet identification Clostridial enteritis (Pig red beak) is characterized by the discharge of red sticky feces. At the time of necropsy, there were more red viscous liquids in the abdominal cavity, and the contents of the small intestine were mostly red with bubbles.
Prevention and treatment of immunization: Sows were injected with divalent or trivalent inactivated E. coli vaccine 40 days and 15 days before delivery.
Drug care: Due to the large number of pathogenic serotypes, immunization alone cannot achieve a complete effect and regular health care must be used to remove pathogens. Recommended program: Yin Qiao powder 2 kg + 500 grams of Wei Jiaxin (or 500 grams of Li Huning) a ton of spices, sows used continuously for 7 days to 10 days before delivery.
Strengthen environmental sanitation: Sows are sterilized with 1,000-fold dilution of Jinweikang before the whole house and fumigated.
Raise the temperature of the pig house: Ensure that the temperature of the house is about 22°C, and the piglet incubate at 28°C～33°C within one week of birth.
For the treatment of diseased pigs, injections are avoided as much as possible, especially excessive injections. This is due to the inevitable stress of the injection. Excessive stress will seriously affect the growth of the pigs. Recommended solution: Prepare oral rehydration salts, and add 5g/200ml of Viagra to the affected piglets. Each time 10ml to 15ml per pig, every half hour to an hour, every day 5 - 8 times. Severe symptoms can be abdominal or intravenous rehydration 50 ml ~ 100 ml.
