Control of trichomoniasis in farmed pigeons

Trichomoniasis is very common in pigeons, which is a kind of multiple protozoa, which does great harm to pigeons and is one of the main diseases of pigeons. The pathogen causing the disease is Trichomonas. The disease is characterized by obvious button-like yellow deposits in the throat mucosa.

The disease is mainly a contact infection, 2Mel 5-week-old pigeons are the most common, and the disease is more serious. Most adult pigeons are asymptomatic carriers. According to the different parts of the insect body, the disease can be divided into pharynx type, visceral type and umbilical type.

Pharynx type: this is the most common and harmful type. Sick pigeons have dysphagia and dyspnea, depressed spirit, digestive disorders, emaciation, lack of food, increased craving and yellow-green sparse feces. Autopsy examination showed that there were yellowish secretions in the pharynx and throat, or a button-like cheese deposit with a clear boundary, and a layer of needle-like lesions were evenly distributed in the entire nasopharyngeal mucosa of some diseased pigeons.

Visceral type: sick pigeon spirit, loss of appetite, increased thirst, hairy, diarrhea, open mouth and neck when breathing, accompanied by cough and wheezing. When the lesion occurred in the digestive tract, there were small white nodules in the crop and esophagus, caseous inside, effusion in the crop, and gray-white nodules on the surface of the liver and spleen.

Umbilical type: inflammation is formed under the navel of pigeons, sick pigeons are dazed, loose hair, eat less, lose weight, the navel is red and swollen, and cheese-like or ulcerative lesions can be seen after mass incision.

Prevention and treatment of this disease is mainly to regularly check the oral cavity of pigeons at ordinary times, that is, to take their oral mucus for microscopic examination. In feeding and management, adult pigeons and young pigeons should be raised separately and pay attention to the hygiene of feed and drinking water.

The following methods can be used for the treatment of the disease: ① mixed 1Jing 2-dimethyl-5-nitroimidazole into 0.05% aqueous solution, drank continuously for 3 days, at intervals of 3 days, drank for 3 days, and drank with furazolidone 0.02% for 2 days to kill bacteria and cut off the nutritional source of Trichomonas trichomonas. Metronidazole (metronidazole) with a ② concentration of 0.05% drank water for 1-2 days. ③ was taken orally with 2-amino-5-nitrothiazole, once a day, 20-40 mg / kg body weight for 7 days. ④ was drunk with 0.5% copper sulfate solution for 3 to 5 days.
