Roundworms are a common parasitic disease of the small intestine. The disease spreads throughout the country, often affecting the growth and development of chicks and even causing a large number of deaths.
Identification of the pathogen
Roundworms, pale yellow or milky white, males 2.67 cm long and females 6.511 cm long, oval, mainly parasitic in the small intestine.
Knowledge rules
Most adult ducks are infected with insects and do not need an intermediate host.
See symptoms
Mental depression, poor development, slow movement, weak appetite, loose feathers, thinness, anemia, pale mucous membranes, and eventually death from weakness.
Diarrhea, sometimes mixed with blood mucus in the stool, and severe infections can lead to intestinal death.
The mucous membrane of the small intestine is inflamed and bleeding, and there are granular abscesses or nodules on the wall of the intestine.
When severe infections can be seen, large numbers of insects can be seen gathering, intertwined, causing intestinal obstruction and even intestinal rupture and peritonitis.
Re-prevention
Strengthen breeding management and create a good environment for duck houses. To make the duck house clean and hygienic, the mat must be kept dry to avoid damp mold.
In earthworm duck farms, commercial ducks can be expelled twice at 15 to 25 days of age and after 1 month.
Principles of early treatment
Insect-driven, prevents secondary infections and increases nutrition.
Tapeworms and tapeworms. It is milky white and banded, and the adult worm is 313 cm long. All parasitize the small intestine, mainly duodenum.
Susceptible animals mainly invade 24-month-old young ducks. After adult duck infection, it is mostly benign and adult.
The epidemic is characterized by pronounced seasonality, generally occurring in late spring, summer and autumn, but less often in winter and early spring. The intermediate master must complete his life history through the middle master. The mature egg segment is automatically detached, the feces are excreted to the outside world, and it develops in the body for 23 weeks, becoming an infectious cysticercosis.
Indigestion, off-white or light green, thin stools, smelly, mixed with mucus and eggs of different lengths.
Mental depression, increased cravings, sagging wings, receding feathers, thin.
When severely infected, the sick duck is thin, anemic, stunted growth and development, and slow movements. Sometimes neurologic symptoms such as unstable walking, neck bending, and paralysis occur. The course of the disease is 15 days and is usually due to severe illness.
Disease observation
Inflammation, hyperemia, bleeding, or ulceration of the mucous membranes of the small intestine.
There are a large number of parasites in the intestinal lumen, and even obstruct the intestinal lumen, which can seriously cause intestinal rupture.
Strengthen disinfection and do a good job in environmental sanitation. Timely cleaning of duck house feces and harmless treatment.
Two kinds of drug-driven insects, commercial ducks about 1 month to deworm, anthelmintic drugs can choose propylthiobenziazole, praziquantel and so on.
