What is the symptoms of E. coli? How to prevent it? – Boultry prevention and control – China Animal Husbandry Website – A useful animal husbandry website
Chicken Escherichia coli disease is acute, chronic bacterial infectious diseases caused by pathogenic E. coli, and all kinds of chickens and chickens of each species can occur. In recent years, as farmed, many farmers blindly increase the amount of farming, causing deterioration of breeding environment, making Escherichia coli disease presented epidemic rising trend, resulting in huge economic losses to farming production.
The sick chicken is depressed, the feathers are muted, loss of appetite, abolish. Partial disease chicken diarrhea, feather under the feather under the feather, contamination adhesion行, 产 产 量, 不 不 不 不 不 不 不 吸 吸 吸 黄 黄 黄 黄 黄 黄 黄 黄 黄 黄 黄Chronic thin, slow growth, joint inflammation.
The pathological examination eye is eye-sighted, heart-packaged liquid, heartbacket is more turbid, there is exudate and myocardial adhesion, cellulose liver Inverseitis. The liver is high, and the liver surface has cellulose-proof oozer exudation, cellulose-boustic bladder, airbag turbid, and cellulose-free exudate. Meat bud swelling, mainly in duodenum, cadec, intestinal film and liver, etc., E. coli bud swelling, follicular membrane congestion, deformed, ovulatory or dark brown. The fallopian tube is congested, bleeding. Census is congested, and the transfusion organ is congested, swollen.
According to epidemiology, clinical symptoms, pathophysiological characteristics, the diagnosis can be made, and laboratory diagnosis is exactly, and the bacterial separation is taken. Identification. Aseptic collected lesions Tissue cardiophalis or liver disease. Inoculated on Yili Lankan agar, most colonies appear black in Yehongmeilan agar, and has metal gloss. Red colonies were inoculated on McCad culture, and growth was repended to the medium. It is diagnosed as E. coli.
Get a good environmental hygiene, strict disinfection
(1) Do a good job in environmental hygiene in the hatching workshop, strictly disinfecting seeds and hatching equipment, preventing seeding and geophysical infections.
(2) Do a good job in the sanitation of the feeding environment. Escherichia coliIt is widely existed in nature, especially infection, and often through digestive tract, respiratory tract and skin trauma, etc., contaminated feed, drinking water, pad, air and food, etc. are the main vector, so do a good job of environmental sanitation, strict Disinfection is one of the important measures to prevent control of E. coli.
During breeding, during breeding, the stable temperature, humidity should be maintained, prevent the thief, to ensure fresh air, prevent Harmful gas pollution, control the breeding density, prevent excessive crowding, reduce stress, and clean up feces, do a good job of environmental sanitation, maintain all the use of clean and health, and use the regular disinfection. In the breeding stage of breeding chicken, in addition to the above, it should pay attention to the transfer group, the stress of the open production, and the chicken pay attention to the stress of artificial insemination and the sinister disinfection of the insemination equipment. Minimize thermal stress, especially for three volts in summer.
Select full price to fit the feed to ensure the nutritional need of the chicken group, so that the chicken group is very strong, improved Anti-patient ability. When it is necessary to be a broken, inoculation, transfer, thermal stress, etc., can add a compound vitamin, trace element, and suitable antibiotics in the feed to improve the nutritional level, increase the disease resistance. . At the same time, vitamin C and vitamin E, reduce stress, enhance immunity, and prevent secondary infection and assisted treatment of diseases.
Active treatment after the onset can adopt one of the following methods to receive the efficacy. There is a special medicine for Escherichia coli: Agrobacterium, which specializes in the treatment of bacterial disease. Western medicine formula, no medicine! Import and export chickens are available, safe and efficient! 300 pounds of water! Concentrated drinking water 4-5 hours, 3-4 days meet! The mortality rate is significantly reduced! You deserve to have! 15_Pord .jpg (317.59 KB, Downloads: 21) Download Attachment 2018-1- 24 09:21 Upload
