Chicken tapeworm is a kind of parasitic disease caused by tapeworm parasitic in the intestinal tract, causing chicken feces thin, egg laying rate decreased, eggshell color light, egg weight light, abnormal egg increased. This disease can occur all the year round, with multiple occurrences from 6 to 11 months. The life history of taeniasis is complex and requires one or two intermediate hosts, mainly ants, beetles, flies and some mollusks. Once infected with this disease, the production performance of laying hens will be damaged, causing serious economic losses to the majority of farmers.
A clinical symptom
Sick chickens are emaciated, unwilling to walk, stand still, and their feathers are loose and dull. How many white, large rice grain sizes, rectangular tapeworm slices can be seen in the excrement discharged by sick chickens, and eggs are found in mature slices.
Two pathological changes
The sick chicken is emaciated, the descending part of the duodenum enters the jejunum about 10cm down, the worms are visible, the small intestinal mucosa is hypertrophic, the cecum tonsil is bleeding and swollen, and other organs have no obvious changes.
Three treatments
Mix with praziquantel 20 mg/kg body weight and concentrate on one dose. Use it again after 5 days. Add 500 grams of cod liver oil per ton of feed for 7 days.
Areca catechu decoction drinking water. The preparation method of betel nut decoction is to use 1 g/kg body weight of betel nut powder (the amount of betel nut powder should not be too large to avoid poisoning), add water to boil betel nut liquid, filter off the residue with gauze, cool down for later use, and generally start to discharge worms within 2 hours after taking the medicine, and last for 1-2 hours. The egg laying rate began to recover after the second deworming of praziquantel and returned to normal after 20 days.
Analysis of the causes of tapeworm infection in 4. laying hens
Chickens are infected with tapeworms by swallowing the intermediate hosts of tapeworms, such as ants, flies, beetles, slugs, and snail lions. Tapeworms will not be infected without contact with these intermediate hosts. Due to the conditions of the chicken house, caged laying hens can mainly contact flies. Therefore, Lilly tapeworms and funnel tapeworms are clinically common. Because slugs and snail lions cannot be contacted, they will not be infected.
In addition to coccidia, caged laying hens are mainly infected with chicken tapeworms, because flies breed in large numbers in summer and autumn, and chickens infect tapeworms by pecking at flies. Chicken nematodes and chicken roundworms are transmitted directly through eggs and do not require an intermediate host. Caged laying hens do not touch the ground, the risk of infection is very low, so caged laying hens to deworming chicken tapeworm as the focus.
At present, the real problem of laying hens and chicken farmers is that retail investors generally have poor environmental sanitation, and biosafety is only a concept for retail investors, and most of them cannot do it. The scale of laying hen households is not as large as that of broiler households. At present, laying hen households are very scattered. In summer, flies fly in chicken houses and tapeworm infection are also very common.
