Use of Salt lick Briquettes «Ivirsalt» on Natural Areas of Preferential Protection in Russia for the Prevention of Parasitic Diseases in Wild Hoofed Animals

Abstract

As test objects served elks and dappled deer infested with helminths. The purpose of this work is to study the efficacy of a new antiparasitic drug «Ivirsalt» used for prevention of helminth infection in wild hoofed animals. The therapeutic efficacy of new anthelmintic drug «Ivirsalt» for nematodosis of wild hoofed animals was tested on 120 dappled deer, 7 elks and 1 roe deeron the territory of Losiny Ostrov National Park (Elk Island), Moscow. «Ivirsalt» is provided in form of salt lick briquettes with a mass of 5 kg containing the active ingredient ivermectin and sodium chloride in the proportion 0, 1: 99, and 9. We put salt lick briquettes to the feed-troughs on feeding places and saline soils based on the average daily salt consumption. The preparation was given within 14 days taking into account that animals approach salt lick briquettes not less than once a week. To determine the efficacy of preparation by the method of coproscopy the fecal samples were collected before and every 10 days after distribution of salt lick briquettes. Materials and methods: Standard lifetime and post-mortem helminthological examinations of animals (coproovoscopy, K.I. Skryabin method of full postmortem helminthological examination, 1928). The research results showed that the intensity of gastrointestinal nematode infestations of dappled deer aged 1,5 to 3 years has decreased by 5,4 times, in deer older than 3 years-by 3,1 times.
