Spread of parasitoses of the gastrointestinal tract of ruminants in the farms of the Kirovohrad and Dnipropetrovsk regions

Abstract

Parasitoses of the gastrointestinal tract of ruminants are quite common all over the world, in particular in Ukraine, as they cause significant economic losses to livestock farms. Animals of all age groups are infected with pathogens of invasions, they often form mixed infections, which are in a complex relationship with the host's organism. Among the helminthiasis of the gastrointestinal tract of cattle, sheep and goats, strongylidoses of the digestive organs became the most widespread. The aim of the work was to investigate the distribution and peculiarities of the course of parasitoses of the gastrointestinal tract of cattle, sheep and goats in the farms of Dnipropetrovsk and Kirovohrad regions. Among the helminthiasis of the gastrointestinal tract of cattle, sheep and goats, strongylidosis of the digestive organs became the most widespread. The aim of the work was to investigate the distribution and peculiarities of the course of parasitosis of the gastrointestinal tract of cattle, sheep and goats in the farms of Dnipropetrovsk and Kirovohrad regions. According to the results of the conducted research, it was established that the average extent of invasion of animals by causative agents of gastrointestinal parasitoses was 59.5 %. Invasive diseases of ruminants are widespread in Dnipropetrovsk (55.2 %) and Kirovohrad (62.5 %) regions. In cattle, the highest rates of EI were in the case of parasitism of strongylides of the gastrointestinal tract (15.8 %) and dicrocelies (7.7 %). In sheep, the highest incidence was in case of parasitism of gastrointestinal strongylides (14.8 %), strongylides and dicrocoelies (11.7 %), strongylides and eimeries (9.2 %), and strongylides and trichurises (8.1 %). The largest share among affected goats is animals with parasitism of strongylidoses of the gastrointestinal tract (16.3 %) and strongylides and trichurises (11.9 %) and strongylides and dicrocelies (9.8 %). The results of the conducted studies show that parasitoses of the gastrointestinal tract of cattle, sheep and goats more often occur as mixed infections. The obtained data on the parasitofauna of ruminants and the peculiarities of the course of invasions will allow to increase the effectiveness of measures to combat and prevent them.
