        <p>Ushbu tadqiqotda O‘zbekiston Respublikasining turli geografik-iqlim mintaqalarida aholi xonadonlari va parrandachilik xo‘jaliklarida boqilayotgan tovuqlar orasida asosiy nematodozlarning tarqalish darajasi, hududiy va mavsumiy dinamikasi o‘rganildi. Tadqiqotlar 2022–2024-yillarda Respublikaning 11 ta viloyatida olib borilib, jami 1682 ta tezak namunasi gelmintokoprologik usullarda tekshirildi. Tadqiqotlarda Fyulleborn, ketma-ket yuvish, Berman-Orlov usulining takomillashtirilgan varianti hamda to‘liq va noto‘liq gelmintologik yorib ko‘rish usullaridan foydalanildi. Umumiy natijalarga ko‘ra, tekshirilgan tovuqlarning 779 tasi, ya‘ni 46,31% nematodozlar bilan zararlangan. Nematodozlar orasida askaridioz 25,45%, geterakidoz 28,59% va kapillarioz 26,28% ekstenszararlanish ko‘rsatkichlarini namoyon qildi. Geografik-iqlim mintaqalari kesimida eng yuqori zararlanish janubiy mintaqada 62,84%, eng past ko‘rsatkich esa sharqiy mintaqada 26,15% bo‘ldi. Mavsumiy tahlil qish faslida 58,23% bilan eng yuqori, bahorda esa 28,97% bilan eng past zararlanish qayd etilganini ko‘rsatdi. Tadqiqot natijalari tovuqlar nematodozlariga qarshi kurashni hududiy va mavsumiy xavfga asoslangan profilaktika tamoyillari asosida tashkil etish maqsadga muvofiq ekanligini ko‘rsatdi.</p>

        <p>This study investigated the prevalence, spatial and seasonal dynamics of major nematode infections among chickens kept in household farms and poultry farms located in different geographical and climatic zones of the Republic of Uzbekistan. The study was conducted in 11 regions of the Republic during 2022–2024, and a total of 1,682 fecal samples were examined using helminthocoprological methods. The study employed the Fulleborn flotation method, the sequential washing method, a modified version of the Berman–Orlov method, as well as complete and incomplete helminthological necropsy methods. According to the results obtained, 779 chickens, or 46.31% of the examined birds, were infected with nematode infections. Among the nematode infections, the prevalence of ascariasis was 25.45%, heterakidosis 28.59%, and capillariasis 26.28%. In terms of geographical and climatic zones, the highest infection rate was recorded in the southern zone at 62.84%, while the lowest rate was observed in the eastern zone at 26.15%. Seasonal analysis showed that the highest infection rate occurred in winter (58.23%), whereas the lowest rate was recorded in spring (28.97%). The findings demonstrate the relevance of organizing control measures against nematode infections in chickens based on preventive strategies that take into account geographical and seasonal risk factors.</p>

        <p>В настоящем исследовании изучены уровень распространения, территориальная и сезонная динамика основных нематодозов среди кур, содержащихся в личных подсобных хозяйствах населения и птицеводческих хозяйствах различных географо-климатических зон Республики Узбекистан. Исследования проводились в 2022–2024 гг. в 11 областях Республики, при этом всего было исследовано 1682 образца фекалий с использованием гельминтокопрологических методов. В исследованиях применяли методы Фюллеборна, последовательного промывания, усовершенствованный вариант метода Берманна–Орлова, а также методы полного и неполного гельминтологического вскрытия. Согласно полученным результатам, из числа исследованных кур 779, или 46,31%, были заражены нематодозами. Среди нематодозов экстенсивность инвазии при аскаридиозе составила 25,45%, гетеракидозе - 28,59%, капилляриозе - 26,28%. В разрезе географо-климатических зон наиболее высокий уровень заражённости отмечен в южной зоне - 62,84%, а наиболее низкий - в восточной зоне - 26,15%. Сезонный анализ показал, что наиболее высокий уровень заражённости регистрировался в зимний период - 58,23%, тогда как наиболее низкий показатель отмечен весной - 28,97%. Полученные результаты свидетельствуют о целесообразности организации борьбы с нематодозами кур на основе принципов профилактики, учитывающих территориальный и сезонный риск.</p>
