In this study, based on the principle of statistical ecology, the the western Fujian mountainous area (seven counties under the jurisdiction of Longyan City) species of domesticated waterfowl parasitic worm populations, as well as the community's ecological distribution conduct a full investigation and analysis, Longyan City domesticated waterfowl provide a scientific basis for disease prevention and control of parasitic worms. 1 infection types: random survey in the city of seven counties (cities, districts), 309 necropsy domesticated waterfowl, which Shanma (Shanman duck) 164 mule duck (Mule ducks) 76 Muscovy duck ( Cairna moschata) 38, Liancheng white duck (Liancheng white duck) 31. Check out a total of 18 kinds of parasitic worms, flukes (Trematoda) and tapeworms (Tapeworm) 6 nematodes (Nematode) 3 acanthocephalan (Acanthocephalan) 1, respectively, belonging to 10 families and 15 genera. Where Ap of flukes, (Amphimerus anatis (Yamaguti, 1933) Gower, 1938), the Oriental times the testis flukes (Metorchis, orientalis Tanabe, 1920), the single testis divided tapeworm (Aploparaksis furcigera (Rudolphi, 1819) Fuhrmann, 1926), Fujian single testis tapeworm (Aploparaksis fukienensis Ling, 1959), Hymenolepis (Hymenolepis the megalops Nitzsch, 1829), a beautiful film shell tapeworm (Hymenolepis venusta Railliet, 1858), spear-shaped sword Taenia (Drepanidotaenia lanceolata Bloch, 1782), mitral valve duck nematodes (Epomidistomum anatinum Skrjabin, 1916), Taiwan beam the first nematode (Streptocara formosensis Sisoff 1912) crack the thorn Schnabelia nematodes (Tetrameres fissispinus Diesing, 1861), most of the shaped spines Capitella (Polymorphus magnus Skrjabin, 1913), 11 kinds of worms The survey found that the newly recorded species. , Infection rate and intensity of infection: parasitic worms communities in this area, domesticated waterfowl parasitic worm infection rate reached 65.37 percent, varying degrees of various parasitic worm infection, there is a big difference. The prevalence and intensity of infection is cracking stab Schnabelia nematodes, respectively, 46.77% and 13.46 (insects), followed by the volume Echinostoma flukes, beautiful Hymenolepis Fujian single testis tapeworm infection rates were 10.64%, 10.65% 9.03%. The intensity of infection were 10.12, 6.58, 6.36. Minimum prevalence and intensity of infection a fine back hole flukes and mostly shaped acanthocephalan infection rates were 0.32%, 0.97%, the intensity of infection of 1.00 and 1.76, respectively. Other 12 kinds of parasitic worms living in a state of moderate infection. 3, the dominant species and distribution type: all parasitic worms groups of random sampling of 309 waterfowl as a ecological community sampling units, calculate the value of ecological characteristics of the 18 kinds of parasitic worm populations, and Ecological analysis of parasitic worms. The results show that: the dominant species for the the crack thorn Schnabelia nematodes and volume spine trematodes Echinostoma revolutum dominant species is beautiful Hymenolepis the Fujian the single testis tapeworms, crown double the helmet the tapeworm (Dicranotaenia coronula), duck flukes, like vertebral low neck flukes (Hypoderaeum conoideum), the divergent single testis tapeworm wedge before Paragonimus (Prothogonimus cuneatus) Oriental times sinensis, duck mitral valve nematodes beam first nematode. Addition to the fine back hole the flukes (Notocotylus attenuatus) and the mostly shaped acanthocephalan are randomly distributed, the other 16 kinds of worms are aggregated distribution, the highest degree of aggregation is large Hymenolepis, followed by a spear-shaped sword Taenia Oriental times sinensis Miyagawa Echinostoma flukes (Echinostoma miyagawai) and duck the mitral valve nematode. 4, stocking a parasitic worm infection of captive mode: the random Necropsy 95 Shanma (41 put duck parasitic worm species survey of the 54 laps duck) and different rearing methods for parasitic worm infections affect studies show : 18 kinds of parasitic worms in 17 kinds of worm infections Shanma overall infection rate was 71.58%, the total average intensity of infection was 13.95. The grazing ducks worm infection rate (85.3%) was significantly higher than the circle duck (61.1%) (P lt; 0.01), mainly for grazing duck trematode infection rate significantly higher than that of the circle duck (P lt; 0.01), while tapeworm duck and nematode infection with circle difference not statistically significant (P gt; 0.05) This shows that the change in the mode of feeding (grazing or captive) mainly affect trematode worm infection Shanma, tapeworm class and nematodes The class of worm infection had no significant effect. 5 strategies for its control: (1) in the ecological environment of Longyan City, should crack the thorn Schnabelia nematodes aquatic animals as intermediate hosts, Volume Echinostoma flukes, beautiful Hymenolepis, Fujian the single testis tapeworm, crown double helmet tapeworm flukes, ducks, like vertebral low neck flukes main object; domesticated waterfowl parasitic worm control as the region and (2) promote waterfowl in captivity, can effectively reduce the parasitic worm infection, and to reduce the occurrence of parasitic worm disease; (3 should focus on preventive measures) of captive ducks the prevention work in nematodes and tapeworms, which control the duck pond waters, aquatic arthropods and snail breeding is an important part in the production of waterfowl breeding. If you still feeding grazing patterns grazing ducks 20-30 days after the start of grazing deworming drugs should be prepared trematodes.
