Spinous fluke disease is a parasitic infection caused by various trematodes in the duck colon, cecum and duodenum of various trematodes of the family Acanthocidae, which is more harmful to young birds.
Duck spiny mouth flukes, these symptoms appear, and old farmers do this.
(1) The pathogenesis parasitizes the duck body, such as the curl spinous mouth fluke and the Miyagawa spinous mouth fluke, and the insect body is long and divided. The first and second intermediate hosts for the growth and development of spiny trematodes are freshwater snails such as small soil snails, vertebral snails, and spinners. Waterfowl are susceptible to the devouring of snails with cysticers.
(2) Clinical symptoms
The duck was listless and refused to stand up and move around. When a small amount of feeling is not more serious, when the chicks are more serious, it can cause poor appetite, poor digestion, and diarrhea. There is mucus in the excrement. Avian iron deficiency anemia, thinning, stagnant growth and development, and eventually decline to death.
(3) Pathological changes
The duck body is more severely dried and thin, hemorrhagic enteritis, and the intestinal canal is filled with catarrhal mucus; In the jejunum, cecum can be seen dark brown content, in the cecum, duodenum found pale pink fine parted insect body, the end of the insect body buried in the human intestinal mucosa, and the suction position has ulceration, with scissors a little bit of force can be scraped off, scraped off the insect body can be intestinal peristalsis curled up. Other internal organs have no eyes to see this.
(4) In the areas where the disease is popular, we should do a good job in solving the work of freshwater snails: every year to solve the problem of livestock to carry out a plan for pest control, and to strictly solve the excrement after pest control. The barn should be cleaned immediately every day, and the excrement is alcohol-free and harmless.
Treatment plan: a bag of 100 pounds of material inside and outside, mixed throughout the day, and used two days every five days for a course of treatment.
