Structure of parasite cenosis of endoparasitoses of ruminants

The infestation was studied and the structure of parasite cenosis ruminants Udmurt Republic characterized. Over period several years research (2016-2020), a diverse parasitophauna identified. According to results research, it established that cattle is mainly invaded by Eimeria spp. , nematodes Strongylata suborder, dicroceliosis dominates from trematode infestations. maximum infection rate noted eimeriosis invasion, during entire time studies varied 87.84 % 77.73 %, which indicates tendency increase invasion stationary problems farms. features competitive relationships are clearly traced in hepatic flukes: dicrocoeliums fascioles. Dicrocoeliotic prevails on average 32 partial manifestation antagonism.When analyzing generic complex cattle, for five years, found largest share occupied spp - 44.35, 30.52, Dicrocoelium 17.52, Fasciola 6.43, Eurythrema – 0.67 Trichostrongylus 0.51 less represented. A retrospective epizootic analysis parasitoses showed sheeps, like have parasitophauna, but first case, detection monoinvasions 3.5 times higher. In sheep cenosis, similar indicators with spp, Strongyloides, Moniezia were found, indices ranged 24.18 27.61. Strongylatosis gastrointestinal tract replaced Strongyloides. significant change also observed group Unlike fasciolosis value 9.5 2019, while not registered at all 2017. complex, moniesiosis occupies main 27.61, may be related conditions keeping, since sheeps grazing long meeting intermediate hosts oribatid mites inevitable.
