Chicks are easy to die from tapeworm infection how to control taeniasis in summer chicken farms

In summer, wet environment, poor sanitary conditions and poor feeding and management are easy to make chickens infected with taeniasis. The main harm of taeniasis is to seize the nutrition of chickens, damage the intestinal wall, metabolite poisoning chickens, a large number of parasites, can block the intestinal tract.

Chicken farm

First, the prevalence of taeniasis: the source of infection of taeniasis is mainly from diseased chickens or wormed chickens, and healthy chickens are infected orally. Chickens of all ages can occur, but the mortality rate of chicks aged 25-40 days is the highest. It is often infected by several kinds of tapeworms. Because the intermediate hosts of taeniasis are widely distributed, taeniasis has a wide distribution. The intermediate hosts are snails, ants, houseflies, beetles, walking beetles and other beetles. after these beetles swallow the pregnant egg segments or eggs of tapeworms excreted with feces, they digest the segments and eggshells, and the escaped six-hook cercariae drill into the body cavity of the beetle. After about 2 to 3 weeks, they develop into metacercaria-like metacercariae, and chickens are infected by eating these intermediate hosts with similar cysticerci, which are attached to the intestinal wall of the host by suckers and apical processes. After about 20 days, it developed into an adult.

Second, clinical features and autopsy changes: clinical common feces are rare and have mucus, and white segments the size of rice grains can be seen in feces, which can peristalsis, decrease the appetite of chickens and increase the amount of drinking water. In severe cases, it can be seen that the movement is slow, feathers are dishevelled, the head and neck are twisted, the egg production of laying hens decreases or stops laying, and finally fails to die.

Third, the changes of autopsy: at the initial stage, the chicken small intestinal mucosal hypertrophy, bleeding or ulcer nodules can be seen, scraping mucosal microscopic examination, tapeworm cephalic nodes can be found. When the adults were parasitized, the intestinal tract of the chicken became thicker and the small intestine was uneven. Ulcers with a diameter of 8~10mm can sometimes be seen in the inner wall of the intestine, and adult tapeworms can be found in the intestinal cavity.

4. Common prevention and control techniques

1. Conventional prevention techniques: timely removal of feces from the chicken house, accumulation and fermentation treatment at the designated place, killing the eggs in the chicken manure by biological heat to prevent the spread of pathogens and polluting the environment; removal of filth from the environment around the chicken house, and spraying insecticides to eliminate intermediate residents; caged, henhouse to take fly control measures; regular inspection of chickens, timely treatment of diseased chickens, adult chickens should be regularly dewormed.

two。 Drug prevention and control technology. The specific drug for the prevention and treatment of taeniasis is praziquantel. When taeniasis occurs, 0.2% praziquantel premix can be used to concentrate on one-off feeding in the afternoon, and the chicken droppings can be cleaned up the next morning. Mix the ingredients according to the amount of prevention every month in summer.
