Prevalence of gastrointestinal helminths in ruminants in Ukraine: a 5-year meta-analysis

The production of environmentally friendly livestock products is currently receiving much attention, especially in the European Union. problem monitoring quality and safety meat milk modern conditions relevant not only for Ukraine but also world community. scientific substantiation methods research on sale subject to invasive diseases important, as product may pose risks consumer. One criteria assessing welfare a herd prevalence helminthiases cattle. Ruminant parasitoses have always been remain separate, often significant, veterinary specialists. Helminths evolved use wide range ecological niches. In this study, we tried quantify among ruminants (cattle, sheep goats) Ukraine. studies were searched online databases. meta-analysis included 15 publications from January 2015 December 2020 which reported spread parasites results show that infestation with gastrointestinal helminths territory 56.7%. Egger’s regression test revealed no significant publication bias. During period pastured farming, stable parasitocenoses are formed body ruminants. caused by (gastrointestinal strongyles, liver flukes, paramphistomas, dicrocelia). They recorded monoinvasions or mixed invasions. Ruminants, according helminthological examination different climatic zones, constantly infested trematodes. Ukraine, presence three species flukes has confirmed ruminants: Fasciola hepatica, Dicrocoelium dendriticum Paramphistomum cervi. Parasitization those negatively affects profitability dairy farming. Trematodes cause economic losses: reduced productivity cows, live weight gain young animals, negative impact reproduction. At same time, fascioliasis socially dangerous humans. According analyzed literature sources, two types cestodes registered Ukraine: Moniezia benedeni M. expansa. epizootic situation regarding nematodes just fraught. That most numerous group helminths, their fauna represented following species: Strongyloides papillosus, Nematodirus spathiger, Bunostomum spp., Oesophagostomum radiatum, Haemonchus contortus, Toxocara vitulorum, Trichuris skrjabini, T. ovis globulosa. It proven cattle more than monoinvasions. highest rates infection observed when polyinvasion namely order Strongylida. papillosus common taxonomic representative, while hepatica lowest infection, sheep. Updated data helminthiasis will expand screening strategy maintain health farm reduce losses.
