Associative helminthiases and protozooses of wild cloven-hoofed animals of the northern silvucultural subzone of Belarus

Objective of research: To evaluate the epizootic situation on parasitoses in wild cloven-hoofed animals from the northern forest subzone of Belarus and estimate the efficiency of broad spectrum anthelmintics. Materials and methods: As research material served ecological and parasitological investigations of wild cloven-hoofed animals at 3 stationary (SNI NP «Braslav’s lakes», SNI «Berezinskiy biosphere reserve», SFI «Begomlskiy forestry») and hunting organizations of forest subzone of Belarus. 498 samples of excrements, samples of organs and body tissues from 119 shot animals were investigated by standard methods. Statistical processing of collected material enabled to estimate the invasion extensity (IE) and invasion intensity (II). Comparative studies of antiparasitic efficacy of timbendazole (22% granulate of fenbendazole) at the dose of 45 mg/kg and a new complex of broad-spectrum anthelmintics (poliparacid and pentavet) at the dose of 50 mg/kg were conducted. Preparations were given to wild cloven-hoofed animals animals with feed within two days at feeding places under production conditions. Results and discussion: Helminthological research revealed that wild boars were infected by 14 helminth species belonging to 4 classes (Trematoda, Cestoda, Nematoda and Acanthocephala). Nematode class is the most numerous and represented by 9 species, Cestoda class contains 3 species, Trematoda and Acanthocephala class - only 1 species each. 13 helminth species belonging to 3 classes (Trematoda, Nematoda, Cestosa) and 1 species of Amery from Sporozoa class were registered among elks. Chabertia (73,1 %) are often found in European roe deer. In 60,9 % of animals at the same time were detected Trichocephalus, Oesophagostoma and Bunostomum (26,6 %). High parasite infection levels in wild animals were registered in mixed coniferous-small-leaved forests. In wild cloven-hoofed animals the nematode class is represented by the largest amount of species. Metastrongylosis is widely distributed in wild boars, mecistocirrosis and strongyloidosis in elks, and trichostrongylosis in European roe deer. New antiparasitic complex drugs Poliparacid and Pentavet have proved highly effective for dehelminthization of wild animals.
