ABSTRACT
Objective of research. A study of species composition of nematodes parasitizing the digestive system of domestic ruminants in Uzbekistan, analysis of seasonal dynamics of infestation and features of the nematode fauna in plains and foothill-mountain areas. Material and methods. In the period of 2014–2015, the digestive tracts of 206 head of cattle and 878 head of small cattle from the farms of Tashkent, Syr-Darya, Dzhizak, Namangan, Kashkadarya, Surkhandarya, Navoiy and Bukhara regions as well as Karakalpakstan autonomous republic were investigated by the method of full helminthological dissection. Results and discussion. 30 nematode species were found in digestive tracts of domestic ruminants of Uzbekistan; 28 nematode species in sheep, 26 species in goats, and 22 species in cattle. The highest rates of extensity of infection (EI) and intensity of infection (II) were detected in Ostertagia ostertagi, Marshallagia marshalli, Teladorsagia circumcincta and Parabronema skrjabini. An increase of EI and II in summer and autumn period was typical for the most of the discovered nematode species. However, EI in O. ostertagi, T. circumcincta, Marshallagia spp. and P. skrjabini was relatively stable in all seasons, but II increased to autumn. 26 nematode species were registered in plains; only 3 of them with high EI and II. 28 nematode species were registered in foothill-mountain areas, 8 of them showed high rates of EI and II. 24 species of nematodes are common in both areas. The obtained results allow us to conclude that it is necessary to improve helminth control of ruminants in Uzbekistan. Alternation of pastures and regulation of grazing, as well as preventive dehelmintization should not be ignored; observe the optimal requirements for feeding and management of animals.

Введение
Скотоводство играет важную роль в экономике Узбекистана, способствуя росту материального благополучия граждан и страны в целом. Отдельные виды продукции скотоводческой отрасли, такие как каракуль, хорошо известны и за пределами республики. Существенный урон скотоводству способны наносить гельминтозы, широкому распространению которых способствуют природно-климатические условия Узбекистана.
Сведения о видовом составе гельминтов домашних жвачных Узбекистана отражены в работах ряда авторов [1, 2, 9–11]. Согласно этим данным, наибольшим числом видовхарактеризуются представители класса Nematoda. Этим фактом обусловлена и обширность задач по изучению нематод домашнего скота в республике. Не до конца выясненными остаются вопросы, связанные с особенностями таксономического состава нематод жвачных на равнинных, предгорных и горных ландшафтах, имеется необходимость конкретизировать сезонную динамику зараженности жвачных различными видами нематод. Проведенные в последнее время таксономические ревизии, затронувшие главным образом нематод семейства Trichostrongylidae [7, 8, 12–16], также пока не были учтены в работах по видовому составу нематод жвачных Узбекистана.
Таким образом, всестороннее изучение нематодофауны домашних жвачных в республике остается актуальной задачей. Основными целями настоящего исследования были получение данных о видовом составе нематод пищеварительного тракта домашних жвачных Узбекистана, анализ сезонной динамики зараженности и выявление особенностей нематодофауны в различных географических зонах страны.
