EFFICACY OF RITRIL USED AGAINST HELMINTHIASES IN SMALL CATTLE

Objective of research: To study the efficacy of Ritril based on Ricobendazole and Triclabendazole used for the treatment of main helminthiases in small cattle. Materials and methods: The efficacy of Ritril was investigated in August-November 2013 against main helminthiases in sheep and goats from private farms «Ushakovka» and «Kozlovka» in Atyashevsky district of the Republic of Mordovia, in experimental farm «Kurilovo» in Podolsk district of Moscow region, and «South of Povolzhye Ltd.» in Bolshechernigovsky district of Samara region. Animal were divided into experimental and control groups. Sheep and goats from experimental groups were intravenously injected with Ritril at a single dose of 0,8; 1,2 and 1,6 ml/10 kg of the animal's mass. Animals of the control groups did not receive the preparation. The anthelmintic efficacy of the preparation was estimated according to the results of examination of animal feces by «control test» before and 10-20 days after the drug application and helminthological autopsy. Berman's method and sequential washing techniques were used for coprological investigations. Helminthological autopsy of liver was conducted in fascioliasis; maw and intestines - strongilatoses of gastrointestinal tract. Results and discussion: Ritril at the dose 0,8 ml/10 kg of the animal's mass showed 98-100% efficacy against monisiasis, dictyocaulosis, nematodiriasis and other strongilatoses of gastrointestinal tract of sheep and goats. Trichocephales, dicrocoelia, fascioles (preimaginal and imaginal stages) were more resistant to the effect of Ritril. It’s recommended, to use a higher dose of preparation against them (1,6 ml/10 kg of the animal's mass). The preparation is well tolerated by sheep and goats and did not cause any local and common side effects.
