Ovcharuk N. Gastrointestinal strongylatosis of cattle in Polissya zone of Ukraine (distribution, diagnostics and control measures)

In thesis summarized the results of the investigations of epizootology, pathogenesis, diagnostics and treatment of gastrointestinal strongylatosis of cattle in the conditions of Polissya zone of Ukraine. Was investigated spreading, seasonal and age dynamics and proved dependence of the invasion level of animals from their housing. Was determining that gastrointestinal strongylatosis in cattle are caused by agents of genuses Bunostomum, Oesophagostomum, Trichostrongylus, Haemonchus, Ostertagia, Nematodirus, Cooperia. A method of larvae strongylates culturing is proposed. In cattle were studied signs of bunostomosis, nematodirosis, oesophagostomosis. Was determining that gastrointestinal strongylatosis taking its course subclinical. High invasion causes an increase of body temperature, pulse rate, respiration and contraction of rumen. Morphological, biochemical and immunological indices of blood was studied and pathomorphological changes in the digestive tract by gastrointestinal strongylatoses with domination Oesophagostomum genus agents were established. The expediency of using anthelmintic drugs of domestic producer science-producing company «Brovapharma»: brontel-10 %, brovalevamizol-8 %, brovermectin for injection in combination with common yarrow grass infusion. The efficiency of brovadez-20 for destroying of agents in the environment (livestock facilities, exercise playgrounds) was studied.
