Comprehensive prevention and control of epidemic disease chicken colibacillosis
In recent years, E. coli disease has been widespread in many chicken farms, and the incidence and mortality rates have remained high. In addition, Escherichia coli is highly susceptible to drug resistance, raising the cost of treatment and causing huge economic losses to the poultry industry. The disease occurs in young chickens, young chickens and adult chickens. The diseased chicks exhibit acute septicemia. The big chickens are mainly sub-acute or chronic infections. If they are affected by other pathogens or stress factors at the same time, the degree of infection will be more serious. In young chickens and laying flocks, the disease often coincides with Newcastle disease, bird flu, bursal disease, transmission, and throat penetration. Symptoms: If eggs are infected with E. coli, chick embryos often die in the late hatching period (before shelling). If infected embryos do not die, most of the hatched eggs show umbilicitis after abdominal enlargement, commonly known as the “big belly buttonâ€, often within 1 week. Dead or eliminated. The first indication of an outbreak of young chickens and adult chickens is usually a sudden increase in mortality, followed by respiratory symptoms. At the same time, the entire flock lacked energy, dried up feet, drained yellow and white dilute feces, and decreased feed intake. The morbidity of the morbid stench was unpleasant, with fibrinous pericarditis, turbidity, thickening of the balloon, attachment of cheese-like substances, hepatomegaly, fibrinous perihepatitis, and a large amount of cellulose in the abdomen, which stuck to the intestinal tract and mesentery. The formation of fibrinous peritonitis, resulting in intestinal adhesions, follicle deformation, atrophy, rupture of the formation of yolk peritonitis. Cause of the disease: Escherichia coli is a common and conditional pathogen, and it develops when the body's resistance declines. 1. Environmental pollution. Feed and drinking water are contaminated by bacteria. Poor health conditions in chicken houses, sinks, troughs, and utensils can all cause this disease. 2. Stress factors. There are a large number of E. coli bacteria in the intestine of healthy chickens, but only 10% to 15% of them can cause diseases. In the case of poor feeding and management conditions, high temperature, frightening, and high feeding density can cause E. coli disease outbreaks. 3. Long-term overuse of antibiotics. There are 85% to 90% of beneficial bacteria in the intestine of healthy chickens. These beneficial bacteria can not only compete with intestinal adhesion points, but also can create an environment harmful to harmful bacteria, thereby inhibiting the growth of pathogenic bacteria. When a large number of long-term use of antibacterial drugs, a large number of The beneficial bacteria were also killed and the flora balance was broken, causing an outbreak of E. coli disease. Preventive treatment: 1. Drug control. Disinfection and fumigation of eggs were performed with benzalkonium chloride and formaldehyde, respectively. Subcutaneous injections of gentamycin to chicks at a dosage of 500 units each could significantly reduce early mortality. If chickens develop Newcastle disease, avian flu, and secondary E.coli disease in the bursa of Fabricius, antibiotics such as fluoroquinolones (norfloxacin, renoxacin, ciprofloxacin, ofloxacin), and Amo can be used. Xilin, florfenicol, polycylocycline, neomycin, gentamycin, chloramphenicol, kanamycin, amikacin, etc., can be used for susceptibility testing and high sensitivity drugs. 2. Vaccine prevention. Because E. coli has many serotypes and the antigen structure is complex, the E. coli vaccine has not been widely used. 3. Apply probiotics. Probiotics are added to the feed to proliferate beneficial bacteria, inhibit the growth and reproduction of harmful bacteria, and thus better maintain the health status of the digestive tract. Environmental control: daily removal of feces, litter, with 100 poisoning, peracetic acid, ring net and other ground disinfection; good ventilation and chicken disinfection; according to the standards of drinking water control; reduce Stimulate the use of antibacterial drugs; conditional chicken farms use pellets or extruded pellets, use the high temperature during the pellet production process to kill most germs; increase the number of quail eggs, reduce the chance of breeding eggs, ground eggs, dirty Eggs must not be hatched.
