Helminthiasis in farm poultry remains one of the most significant veterinary problems in households in the central regions of Uzbekistan, where poultry farming plays an important role in food security and sustainable development of the agricultural sector. The aim purpose of this study was to determine the prevalence of the main types of intestinal nematodes in chickens in three key regions of the country – Jizzakh, Syrdarya, and Samarkand provinces – and to evaluate the effectiveness of antiparasitic therapy using tetramisole-based drugs. Between 2022 and 2024, 747 chickens were examined, with helminthological and coprological analyses of faecal samples showing that the overall infection rate was 52.07%. The distribution of infected birds by region revealed significant variability: the lowest level of infestation was recorded in the Jizzakh region Region (41.9%) and the Syrdarya region Region (50.6%), and the highest in the Samarkand regionRegion, where 58.57% of birds were infected. The main nematodes identified were ascaridiosis with an infection rate of 32.8%, heterakidosis with 32.53%, and capillariosis with 37.48%. Such a high prevalence indicates a wide range and pronounced endemicity of helminthiasis in these regions. Antiparasitic therapy with a tetramisole-based drug demonstrated high efficacy: 92.86% after the first course of treatment and 100% elimination of parasites after repeated use. The results of the study emphasised the need to adapt veterinary preventive measures to regional characteristics, which will reduce economic losses in poultry farming and improve poultry health indicators in households. The practical significance of the work study lies in the formation development of scientifically based recommendations for optimising helminthiasis control and prevention programmes, which is an important factor in increasing productivity and biosafety in the agricultural regions of Uzbekistan
