E.coli disease symptoms and prevention in ducks
Duck colibacillosis is a common disease in duck populations. It is an acute septic communicable disease caused by E. coli, also known as duck E. coli septicemia. E. coli is widely distributed in nature, ducks of all ages are susceptible, especially ducklings most susceptible, the incidence of wet winter and spring more common, the incidence of up to 70% -90%. When the hygienic condition of the duck farm is poor, the ground is damp, the ventilation in the house is poor, the smell of ammonia is large, the breeding density is too large, etc., and they are often susceptible to disease. The main source of infection of E. coli in ducks is diseased poultry and infected poultry. Their corpses and feces, contaminated feed, drinking water, ponds, feeding sites, tools, and eggs are also sources of infection. Healthy ducks are infected through the digestive tract or respiratory tract. Escherichia coli, but not necessarily the immediate disease, when the body's resistance to reduce or suffer from other diseases, the bacteria inhabit the body will take the opportunity to enter the blood vessels, with the distribution of blood throughout the body, causing sepsis or other diseases. It can also enter the blood through skin wounds, causing sepsis. Use the kingpin dry duck-type fermentation bed to raise ducks (click here for details) to ensure hygienic conditions in the duck farm. Dry litter, duck excrement is fermented in the fermentation bed, and E. coli is eliminated, reducing the chance of duck infection.
Symptoms of colibacillosis in ducks E. coli disease in ducks is mostly acute septicemia. Newly hatched ducklings have weak physique after onset. They contract the eyes and neck and have a large abdominal circumference. They often have diarrhea and die due to septicemia. Larger ducklings After onset, the spirit is euphemism, loss of appetite, drooping wings, standing sideways, head bent downwards, touching the ground at the corner of the mouth, often with mucus secretions at both eyes and nostrils, some diseased ducks pull green loose stools, difficulty breathing, often due to sepsis Or constitutional failure, dehydration and death; adult sick ducks lying and lying, do not want to move, when the standing abdominal bulging pendulous penis-shaped, palpation of the abdomen with a sense of fluid fluctuations, puncture fluid ascites.E. coli prevention and treatment methods for ducks 1. Strengthen feeding and hygiene management Strengthen the feeding and management of ducks, strictly guard the epidemic prevention hygiene management system, and introduce breeding eggs or ducklings from duck farms without E. coli disease. Eggs, hatchery rooms and related appliances can be sterilized with 0.1% strong disinfection or 0.03% poisonous liquid. Daily routine use of oregano oil premix can be mixed with 1.25 g/100 kg of feed for preventive work. The use of a golden duck dry-spreading bed to raise ducks can guarantee hygienic conditions in the duck farm, eradicate bacteria in the feces, beneficial bacteria in the fermentation bed and beneficial substances such as bacterial proteins can improve the immunity of ducks. More to prevent bacterial infection.
Second, vaccination of E. coli disease vaccine farms can be based on the actual situation, inoculation of multivalent E. coli inactivated vaccine.
Third, the duck colibacillosis treatment intramuscular gentamicin, 2 mg -3 mg / kg body weight, kanamycin 10 mg -15 mg / kg body weight, 3 times / day, once every 3 days - 5 days. Norfloxacin was mixed and fed by 0.01% condiments for 3 days to 5 days; compound sulfachlorazine sodium powder was fed at 20 mg/kg body weight for 7 days; terramycin powder was 60 mg to 250 mg/kg. Mix water and drink, use 5 days to 7 days. The above drug treatment is better, but pay attention to the emergence of drug resistance. The use of duckweed fermentation bed ducks can increase the duck's resistance to disease and reduce the amount of antibiotics used. Symptomatic treatment for the corresponding symptoms.
