The thesis deals with the study of the peculiarities of helminth fauna complexes formation in one year lambs, lambs aged 1-2 years and adult sheep during two scheduled deworming, spring (April) – before deporting of pasture animals on summer-mountain pasture and autumn (November) – before deporting of pasture animals on the winter-lowland pastures. Firstly received scientific data about the peculiarities of epizootology of the helminths in sheep and helminthological state of environmental objects as pastures and trails for deporting of animals in ecosystems of Mountain-Shirvan economic zone. During the year the pathogens of nematodes from the family Strongylidae, Trichostrongylidae, Trichonematidae, Ancylostomatidae and species of Dictyocaulus filaria; cestodes – Moniezia expansa i M. benedeni; trematodes – Fasciola hepatica and F. gigantica and Dicrocoelium lanceatum was discovered in sheep with the average total invasion extensiveness of 31.0 %. As a result of studies it was found the highest infestation of sheep with the Strongylata of gastrointestinal tract in July-October period and April, with the Fasciola in April and October, with the Dictyocaulus in April, with the Moniezia in September and October, with the Dicrocoelium in October. Вased on experimental researches the «Brovatriol» pharmacy was designed in the form of large tablets (3 g), that includes three ADRs in the amount (mg) of: triclabendazole – 165; albendazole – 330; praziquantel – 120. The pharmacy belongs to the third grade of toxicity (toxic substances moderate) for intragastric injection of the «Brovatriol» pharmacy and the value of laboratory animals DL100, DL50 and GOST 121.007-76. During the deworming of sheep with the «Brovatriol» in the therapeutic dose using group method, anthelmintic is highly effective against the mature and young Fasciola, against the Dicrocoelium, Moniezia, Dictyocaulus and the Strongylata of the gastrointestinal tract. The proposed method of the sheep deworming with group method with drinking water scheme and its use in their pasture maitanance is the most practically feasible for implementation of the livestock preimahinal deworming that would provide preventive and high economic efficiency.
