Abstract

A study of the therapeutic efficacy of a new drug form of eprinomectin-Elivec in the strongylatoses of the gastrointestinal tract of young cattle was carried out on spontaneously infested animals in the Moscow Region. Elivec was prescribed in a dose at the rate of 1ml per 10kg of animal weight cutaneous once. The basic drug was Ganamectin in the recommended dose subcutaneously once. According to the results of coproskopic studies, after 10 and 30 days all the treated animals were free of invasion. In the production test, the efficacy of Elivec was cumulative with strongylatoses of the gastrointestinal tract of heifers: EE - 96.7%, IE - 98.86% and of Ganamectin EE - 95%, IE - 98.04%. In the course of the research, to differentiate invasive larvae of strongylatoses up to the genus, 20 samples of feces from the young were cultivated in a thermostat at a temperature of 26 °C for 10 days. Larvae of strongylatoses differed from each other in the number and shape of intestinal cells, as well as in the size of the larvae themselves and their tail end. In the examined samples, invasive larvae of gastrointestinal strangulation belonging to the genera Trichostrongylus, Ostertagia and Bunostomum were examined.
