Fluke disease affects duck egg laying how to control duck tracheoclonorchiasis

Duck tracheoclonorchiasis is caused by melon-shaped caecum trematodes and navicular trematodes. Melon-shaped caecum trematodes are parasitic in the trachea, air bag and esophagus of ducks, while navicular tracheotrematodes are parasitic in the trachea, bronchi, air sacs and infraorbital sinuses of ducks.

Duck

The intermediate hosts of duck tracheoclonorchiasis are vertebral snail and flat snail. In summer, when ducks graze in rivers, ponds and other waters, they become infected after swallowing snails containing metacercaria, affecting growth and egg laying. The case fatality rate is generally about 3% and 5%.

The performance of sick duck: dyspnea, wheezing, neck stretching and mouth opening. Due to the damage of the tracheal mucosa of the duck, it is congested and the inflammatory exudate increases, causing the sick duck to make a "gurgling" sound when breathing. When trematodes move to the upper end of the duck's trachea and block the trachea, it can cause the duck to suffocate and die suddenly.

For the treatment of diseased ducks, it was often used to inject 0.5-2 milliliters of iodine solution or 1500 sodium salicylate solution from the glottic fissure of ducks, which should be injected again every 2 days. Now the treatment with praziquantel has a good effect, the dosage is 50 mg per kilogram of body weight, mixed with feed or made of rice into pellets, once a day for 3 days.
