How to prevent and treat colibacillosis in meat ducks?

At present, duck farms and farmers in China have recognized that E. coli disease is an environmental disease. Therefore, the feeding density of ducks should be reduced, the feces and sewage in the duck house and the sports field should be cleaned up in a timely manner, so as to provide a comfortable and clean breeding environment for the ducks, keep the duck house dry and hygienic, improve ventilation, reduce dust, reduce ammonia content, and regularly disinfect the duck house, sports field, utensils, equipment, etc. Adopt the "all-in, all-out" system to thoroughly disinfect the inside and outside of the duck house; Immunization with a specially formulated E. coli vaccine has some preventive effect.

Drugs** Gentamicin, oxytetracycline, sulfonamides, enrofloxacin, ciprofloxacin, etc. can be tried. If 70 mg of enrofloxacin or ciprofloxacin is added to the feed, or 30 mg kg of enrofloxacin or ciprofloxacin is added to drinking water, the drug can be used continuously for 3 5 days, and a better ** effect can be obtained.

Meat duck drug-resistant E. coli, with isopamicin or meropenem, 100 shots.

Escherichia coli is a kind of pathogen that will be carried in the body of birds, and it will not get sick in the case of normal physique of birds, and when there are small problems in the body of birds, or when there are diseases such as colds and other diseases that cause immunity to decrease, it will be sick, so most diseases will be accompanied by E. coli. Therefore, to prevent E. coli disease, it is necessary to first improve the autoimmunity of birds, and ducks with diseases can be isolated as soon as possible, and florfenicol can be used as a simple preventive measure.

The main prevention of this disease is to do a good job in the sanitation of feed and drinking water in the duck house, improve the resistance of the duck flock, and eliminate various adverse factors that affect the growth of the duck. Pay attention to the ventilation and dryness of the duck house, do not feed moldy and deteriorated, polluted feed, clean and hygienic drinking water, pay attention to the insulation of ducklings, the feeding density should not be too large, and the nutrients of the feeding 4 should be comprehensive. Otherwise, even if some drugs are very effective for the disease, the condition will be ** after stopping the drug.

Duck houses and utensils should be disinfected regularly, usually once every 2 weeks, and twice a week when the disease is found.

(1) Preventive measures, mainly to do a good job in environmental sanitation and strengthen the management of duck breeding. In particular, attention should be paid to the following: check whether the water source is contaminated with E. coli and replace it completely if so; Pay attention to the heat preservation and feeding density during the brooding period, improve ventilation, reduce dust, be diligent in manure removal, and reduce the content of ammonia; Duck houses, incubators and utensils are cleaned and disinfected frequently; Duck farms should collect eggs in a timely manner.

Antibiotics can be used to prevent the occurrence of parasites and other diseases. (2) Inoculation of vaccines, the commonly used vaccines in China are Escherichia coli formaldehyde inactivated vaccine and Escherichia coli inactivated oil milk vaccine, it is best to use spontaneously diseased duck isolated E. coli strain to prepare multivalent vaccine for immunization, which can effectively control the occurrence of the disease.

Under normal circumstances, it is best to strengthen the management of feeding, it is best to disinfect the duck house frequently, ventilate, pay attention to drinking water, feed, and if possible, the duck flock can be collectively vaccinated

1.Do a good job of disinfection of duck eggs, incubators and hatchers, and the hatchery hall and its utensils should be cleaned and disinfected frequently.

2.Implement the "all-in, all-out" system, strengthen disinfection, brooding room, net bed and feeding equipment must be thoroughly cleaned and disinfected before reuse;

3.Strengthen management, reasonable density, pay attention to ventilation, change bedding frequently, and keep the house clean and dry.

<>1 Hail causes.

Wild duck colibacillosis is a bacterial infection caused by certain serotypes of Escherichia coli. The disease is mainly transmitted through the digestive tract, and can be transmitted through eggs contaminated with germs, feces and secretions of diseased wild ducks, as well as contaminated feed, drinking water, utensils, bedding, and activity places. The disease can occur all year round, but it tends to occur frequently in the rainy, humid and muggy autumn season.

2 Symptoms. The incubation period of the disease is 1-3 days, with sepsis being the most common. It is more common in mallards between 3 and 10 weeks of age.

Acute sick ducks died suddenly without showing symptoms, and the case fatality rate was as high as 50%; The main symptoms of non-acute sick ducks are: depression, loose feathers, inflammation of the conjunctiva, loss of appetite or even refusal to eat, nasal discharge, neck stretching and breathing, drowsiness, diarrhea, yellow-white or yellow-green thin feces, paralysis of the feet, unsteady standing, etc.

3 Prevention. E. coli is not very resistant and can be killed in 15 minutes at a temperature of 60. General disinfectants can kill the bacteria.

The preventive measures mainly include: Strengthen health management, regular cleaning and disinfection, ensure the hygiene of feed and drinking water, and strictly prevent other poultry from entering: The hatchery room and brooding room should be fumigated and disinfected with formaldehyde before and after use, and the eggs must be cleaned and disinfected before they can be incubated; For immunoprophylaxis, subcutaneous injection of E. coli multivalent ultrasonic-inactivated bacteria seedlings (less than 1 month old) in the back of the neck of wild ducks, generally 14-20 days old for the first time and 18-20 weeks of age for 1 time.

4．**。Kanamycin or spectinomycin, 30-40 mg intramuscularly per kilogram of body weight, once a day for 3 days; Streptomycin is injected intramuscularly at 10,000 units per kilogram of body weight, once a day for 3 days; With gentamicin, intramuscular injection according to the amount of 10,000 units per kilogram of body weight, 2 times a day, and chloramphenicol raw powder, evenly mixed into the feed according to the amount of feed section, the effect is obvious.

There is a high probability that there will be difficulty breathing, abnormal bowel movements, it is likely to lead to septicemia, dehydration, some sticky discharge from the eyes and nostrils, loss of appetite, and listlessness.

Ducks have a bad appetite and look sluggish, ducks have difficulty breathing, cough symptoms, and diarrhea can become very lightweight, these diseases are all duck colibacillosis.

It can cause acute and chronic diseases, and then it can also cause sepsis, duck plague syndrome, which can lead to respiratory infections, and also cause ducks to lose energy and appetite.

Summary. Hello dear, duck Richeri disease, also known as duck infectious serositis, is a contact, acute or chronic, septicaemic infectious disease. The main features are fibrinous pericarditis, fibrinous perihepatitis, fibrinous balloonitis, caseating salpingitis, arthritis, and paralysis.

Hello dear, Richeri duck cave is also known as duck infectious serositis, which is a contact, acute or chronic, septicamic infectious disease. The main features are fibrinous pericarditis, fibrinous perihepatitis, fibrinous balloonitis, caseating salpingitis, defibrillation, arthritis, and paralysis.

A variety of antibiotics and sulfonamides have certain prevention and treatment effects on this disease. However, due to the fact that Pasteurella pestisis is prone to drug resistance, it is best to do antimicrobial susceptibility tests before taking drugs, screen for high-sensitivity drugs, and pay attention to the alternation of drugs. The following drugs are commonly used:

Chloramphenicol was mixed orally for 3 5 days; Gentamicin is injected intramuscularly at 4000 8000u kg body weight, 1 2 times a day, and the book is taken for 2 3 days; Regomycin was mixed orally according to the active ingredient of the drug for 3 5 days; The compound antibacterial net ratio mixture was taken orally for 4 6 days; sulfaquixaline, mixed orally for 3 days in proportion, and then fed for 3 days after stopping the drug for 2 days; Penicillium sensitive socks and streptomycin intramuscular, 10,000 U each for ducklings and 480,000 U for young and middle-aged ducklings.

Prevention and control measures. 1. Do a good job in environmental sanitation and disinfection, strengthen feeding management, strictly disinfect eggs and incubation facilities, prevent germs from being transmitted through eggs, control the mutual infection of newborn chicks, eliminate various pathogenic causes, ensure the cleanliness of serving materials and drinking water, pay attention to the insulation of brooding period, appropriate feeding density, and never mix batches of chickens of different ages, and regularly disinfect the cracked chicken coop and utensils.

2. Rational use of antibiotics Because Escherichia coli is prone to drug resistance, drugs that are rarely used or never used should be used, and those with a good article are best selected according to the results of drug susceptibility tests. According to the experimental research, the clinical application + list of drugs has a good effect: enrofloxacin, cephalosporins, gentamicin, Baizhiqing, fluoromanoic acid, spectinomycin, ampicillin, bacillin, oxytetracycline, dysentery, etc.

When the disease is severe, the chickens should be sorted out, classified, and the dying chickens should be eliminated immediately; Sick chickens with obvious symptoms should be selected first, and all of them should be injected with penicillin, streptomycin, gentamicin and other drugs1?2 times, after the symptoms of Zhipei Li disappeared, the chickens in the same group who appeared to be healthy were prevented with well-absorbed medicine drinking water or mixture for 3 5 days.

Prevention and control measures. 1. Do a good job in environmental sanitation and disinfection, strengthen feeding management, strictly disinfect eggs and incubation facilities, prevent germs from being transmitted through eggs, control the mutual infection of newborn chicks, eliminate various pathogenic triggers, ensure the cleanliness of serving materials and drinking water, pay attention to the insulation of brooding next to the period, appropriate feeding density, different age batches of chickens must not be mixed, and regular disinfection of chicken coops and utensils.

2. Rational use of sensitive antibiotics Because Escherichia coli is easy to develop drug resistance, it is necessary to choose drugs that are rarely used or have not been used, and it is best to choose according to the results of drug susceptibility tests. According to the experimental research, the clinical application + list of drugs ** has a good effect: enrofloxacin, cephalosporins, yunajigentamicin, Baizhiqing, fluoromaric acid, spectinomycin, ampicillin, bacterium, oxytetracycline, dysentery, etc.

When the disease is severe, the chickens should be sorted out, classified, and the dying chickens should be eliminated immediately; Sick chickens with obvious symptoms should be selected first, all with penicillin, streptomycin, gentamicin and other drugs injected 1 2 times, after the symptoms disappear and then mixed in the population, the same group of chickens that seem to be healthy with better absorption of the drug drinking water or mixing 3 5 days for prevention.
