EFFICACY OF NEW BROAD SPECTRUM ANTHELMINTIC DRUGS FOR TREATMENT OF HELMINTHOSIS IN CATTLE IN CONDITIONS OF VOLOGDA REGION
Objective of research: to study the efficacy of new broad spectrum anthelmintic drugs for tre ating main helminthosis in cattle. Materials and methods: 4 experiments were conducted to test the anthelmintic drugs used against helminthosis in cattle in conditions of Vologda region. In the fist experiment were involved 125 animals with fasciolosis divided into different groups by 25 animals in each group which got the single doses of: fascocide at a dose of 10 mg/kg, helmicide - 5,25 mg/kg according to the active ingredient, albendazole - 15 mg/kg, fezol - 14 mg/kg, alben - 10 mg/kg The efficacy of preparations was registered according to the results of coproovoscopy before and 45 days after dehelmintization. The second experiment was performed at paramphistomosis in cattle with the use of the same preparations. In the 3, 4 and 5 experiments we used the same preparations at moniesiosis, strongylatozis of the digestive tract and dictyocaulosis in young cattle, respectively. Results and discussion: at fasciolosis of cattle the drug efficacy was: for fascocide and helmicide - 100 %, fezol - 92, alben - 76 %, at paramphistomosis 100 %, 84, 80 and 68 %, respectively. The drug efficacy at cattle moniesiosis was: of helmicide and fezol - 100 %, alben - 92 %, and at gastro-intestinal strongylatozis: of fezol- 100 %, helmicide - 92 and alben - 84 %. At dictyocaulosis the efficacy was: of helmicide - 88 %, fezol - 92 and alben - 80 %.
