Diagnosis and treatment of chicken schistosomiasis

Prozomosis is a common trematode disease in chickens. The incidence of adult hens is high, and it is one of the main reasons that affect egg production and malformed eggs.

The pathogen is preprosortium, also called fallopian flukes. The insect is flat like a small piece of leaves, brownish red, about 3 to 9 mm long, about 1 to 5 mm wide, and the head has two suckers, and the body relies on it for fixing and living. Adults parasitize the hen's reproductive organs, mainly in the bursa of the fallopian tubes and cloacas. The eggs are excreted into the water as the feces are excreted, and hatch into the larvae in the snail - the cercariae; the cercariae swim in the water after leaving the screw and are eaten by the larvae and continue to develop in the body. The chicken eats pupa or larvae. Afterwards, it will become ill. In chickens, larvae of flukes fall down the intestine into the cloaca and into the bursa or fallopian tube, where they continue to develop into adults.

At the beginning of the disease, the parasites become inflamed. The cloaca of hens often leucorrhea; then, because the parasite destroys the mucous membranes and glandular tissue of the fallopian tubes, the normal function of the hens' egg laying occurs obstacles, and abnormal eggs such as non-yellow eggs and soft shell eggs are often produced. When infected chickens are poisoned by trematodes, they have obvious systemic conditions. They do not eat, lose weight, do not want to walk around, lose their abdominal feathers, lose their cloacal cavity, and become hyperemic. At the time of necropsy, inflammation of the fallopian tubes and cloacas can be seen, and broken eggs and proteins are common.

Diagnosing normal hens with leucorrhea, decreased egg production, and production of malformed eggs can be suspected as the disease. Fecal examination can be confirmed if eggs are found. Combining necropsy with worms is more accurate.

The disease was treated with carbon tetrachloride and the dose was 1.5 ml per bird. Feed the chicken before the injection to make it full and easy to inject. Or each adult chicken oral hexachloroethane (0.2 ~ 0.5 grams), can be made into the water suspension mix feed, once a day, and even served three days. A solution of 5% trichlorfon may also be used to smear cloacas and the inside of the fallopian tubes. Good results can also be obtained.

Prevention of concentrated waste disposal of feces to prevent eggs from entering the water to cut off their life cycle.
