Symptoms and control measures of taeniasis in geese

Xiphotaenia is a common parasite in the small intestine of geese, which often causes Xiphotaenia infection in geese. The disease is especially harmful to young geese and can cause large numbers of deaths. Taeniasis has obvious seasonality, generally occurs in late spring to summer and autumn from April to October.

1. Pathogen and epidemic characteristics of Taenia gladiata disease

Taenia sagittata is the pathogen, belonging to the hymenotheca family. It is a large insect with milky white color. The insect body is about 13 cm long and lances. The head section is small, with 4 suckers on it, 8 small hooks on the apical process of the insect, and a short neck. The chain body consists of 20 - 40 segments, narrow at the front end and gradually widening at the back, and the final segment is about 5 - 18 mm wide. Three testicles appear when the segments mature. The testicles are oval and lie on one side of the inner genital pore of the lanceolate tapeworm. On the outside of the testicle are the ovaries and ovarian glands. At the lateral margin of the upper corner of the segment is the genital pore. The eggs are oval in shape and not wrapped in egg bags.

The disease is widespread and endemic. Goslings older than 20 days old were the main targets. Clinically, it is mainly seen in geese of 1~3 months old, but the earliest age of disease is 11 days old, which may be infected by drinking water after hatching. Mild infection usually has no obvious clinical symptoms, adult geese infected, more recessive after becoming a goose with worms.

2. Clinical symptoms

Adult geese infected with aria generally have mild symptoms, but the infected young geese have obvious systemic symptoms. The first one is diarrhea caused by digestive dysfunction, and the white feces are mixed with white tapeworm segments. In the later stage of the disease, appetite is lost, feathers are loose and dull, and they often live alone and do not want to walk. The seriously infected young geese often have nervous symptoms, such as walking, movement disorder, loss of balance, and inability to stand up when they reach the ground. After the disease, they often cause death. The disease duration is 1~5 days.

3. Prevention and control measures

1 Prevention. The geese of different ages should be raised separately, and regular deworming should be carried out on young geese and adult geese at least twice a year in spring and autumn to reduce environmental pollution and spread of pathogens.

2 Treatment. Commonly used drugs are praziquantel taken orally at 10 - 15 mg/kg body weight, or albendazole taken at 50 - 100 mg/kg body weight, or thiodichlorophenol taken at 150 - 200 mg/kg body weight. To ensure efficacy, the above drugs should not be administered together, because they should be administered one by one.
