The research on the study of parasitofauna in wild boars, carried out by the collaborators of the Laboratory of Parasitology and Helminthology of the Institute of Zoology of MECC, from various natural biotopes of the Republic of Moldova, where they populate, have shown a high level of their infestation with various parasitic agents such as: Dicrocoelium lanceolatum -16.5%; Strongyloides ransomi -25.6%; Metastrongylus elongates -16.8%; Ascaris suum 22.6%; Hypostrongylus rubidus -26.4%; Globocephalus urosubulatus -56.4%; Gongylonema pulchrum-5.8%; Physocephalus sexalatus - 8.7%; Oesophagostomum dentatum -23.2%; Trichocephalus suis -15.5%; Macracanthorhynchus hirudinaceus 12.4%; Eimeria scabra - 63.2%. The supplementary feeding and deworming process of the wild boars, according to the invention, envisages its provision during the cold winter period also coinciding with their reproduction period (December-February) when they face nutritional deficiency and need supplementary feeding, in this case specifically defined 1 dose per capita in the form of briquettes (4 pieces of 400.0g), a total of 1600.0g / boar / day, administered in two halves of 14 days, by use of the feeders. The result of the scientific work consists in defining a composition for the supplementary feeding and deworming of wild boars which proved to be effective, harmless, relatively inexpensive and simple deworming measure complex, ensuring simultaneously supplementary feeding and deworming of wild boars during the cold season.
