Abstract
The paper demonstrates the prospects of applying Arabinogalactan for mechanochemical modification of physicochemical and biological properties of antihelminthic substance. The study evaluates the parasitocidal effect of ivermectin (IVER) and albendazole (ABZ) compounds with Arabinogalactan (AG) in the form of solid dispersions (RD) in sheep intestinal helminthiasis. The authors tested compositions of new specimens with the active substance (DV) of ivermectin with three batches of arabinogalactan from different manufacturers in the ratio of 1:10 and compositions of IVER+ABZ+AG in the ratio of 1:1:10. The experiments on parasitocidal activity of compositions in intestinal helminthiasis were carried out on spontaneously invaded sheep in Shebala district of the Republic of Altai, where 16 experimental and 2 control groups of animals were arranged following the principle of analogues. The sheep received the specimens on an individual basis: as a water suspension orally; composition of IVER+AG dosed as 0,1; 0,05 and 0,025 mg per a kilo of animal weight; composition of IVER+ABZ+AG - in calculation of IVER+ABZ - 0,1 and 0,2 mg of water suspension, albendazole 1, 2, 3 and 5 mg per 1 kg of animal weight. The experiment has shown that parasitocidal activity of laboratory samples of mechanical compositions of ivermectin and different in degree of purification of AB lots do not differ significantly. It is supposed that parasitocidal compositions can be used for non-pharmacopoeia AG samples of animals, which will reduce significantly the cost of the specimen. The efficiency of the composition of IVER+AG dosed 0.1 mg per 1 kg of animal weight is significantly higher than that of the initial specimen. Mechanical composition IVER+ABZ+AH dosed 0.2 mg of hemectin and 2 mg of albendazole per a kilo of animal weight is highly effective (100%) against sheep intestinal helminths and it assumes the possibility of significant (five times) decrease of AHZ dose in the composition with AH without loss of helmintocidal activity.

Summary
Соискатель альбендазол, механообработка, 1Горно-Алтайский НИИ сельского хозяйства – филиал эффективность. Цель работы – показать перспективность использования арабиногалактана для механохимической модификации физико-химических и биологических свойств антигельминтных субстанций и оценить паразитоцидную эффективность композиций ивермектина (ИВЕР) и альбендазола (АБЗ) с арабиногалактаном (АГ) в виде твердых дисперсий (ТД) при кишечных гельминтозах овец. Испытывали композиции новых препаратов с действующим веществом (ДВ) ивермектина с тремя партиями арабиногалактана различных производителей в соотношении 1:10 и композиции ИВЕР+АБЗ+АГ в соотношении 1 : 1 : 10. Эффективность композиции ИВЕР+АГ в дозе 0,1 мг на 1 кг массы животного существенно превышает таковую исходного препарата. Механокомпозиция ИВЕР+АБЗ+АГ с дозировкой ивемектина 0,2 мг и альбендазола 2 мг на 1 кг массы животного высокоэффективна (100%) против кишечных гельминтов овец и предполагает возможность существенного (пятикратного) снижения дозировки.
