This paper presents the results of laboratory studies on a pre-sowing electrical treatment method aimed at enhancing the germination capacity of corn seeds. The study investigates an electrotechnological approach based on the application of ultraviolet radiation (UVR), in which the effect is achieved through the electrical stimulation of seeds. An analysis was conducted to determine the optimal treatment parameters, including ultraviolet wavelength, exposure distance, and irradiation duration applied prior to sowing. The results identify favorable combinations of these parameters that contribute to improved germination performance and early seedling development.

This study evaluated the potential of Acalypha wilkesiana leaf powder (AWLP) to mitigate the toxic effects of Aflatoxin B₁ (AFB₁) in broiler chickens. A 3×3 factorial design was used to assess the interaction between three levels of AFB1 (0, 0.25, and 0.5 mg/kg) and three levels of AWLP (0, 250, and 500 mg/kg) in the diets of Cobb 500 broilers. One hundred- and eighty-nine-day-old chicks were randomly assigned to nine dietary treatments over a 6-week feeding trial. Oxidative stress biomarkers and cellular stress markers were evaluated. AFB₁ exposure significantly induced oxidative damage in brain and muscle tissues, as reflected by elevated lipid peroxidation and reduced antioxidant enzyme activities (catalase and glutathione peroxidase). AWLP supplementation at 250 mg/kg reduced lipid peroxidation, and significant interaction effects were observed for several parameters, including NF-κB, HSP70, and oxidative stress markers, confirming AWLP’s dose-dependent modulatory role. Although AWLP demonstrated antioxidant and hepatoprotective benefits, it was insufficient as a standalone remedy for AFB₁ toxicity. These findings suggest that AWLP at moderate levels may serve as a functional phytogenic additive in poultry feed, particularly in regions prone to aflatoxin contamination, but further integration with other detoxifiers is recommended.

This article presents the helminth fauna, species composition, and infestation rates of the wels catfish found in the territory of Karakalpakstan. As a result of the research, 15 species of parasitic worms belonging to 3 phyla, 4 classes, 10 orders, and 13 genera were discovered. Of these, 6 species are trematodes, 2 species are cestodes, 2 species are acanthocephalans, and 5 species are nematodes.

Cattle breeding is one of the most important branches of animal husbandry, which, along with livestock products (meat, milk), plays a large role in providing our people with raw materials for the light industry.In this article, the main task facing livestock specialists today is to increase the number of pedigree cattle in cattle breeding, to study the adaptation of the animal organism to the external environment when forming the most productive herds of cattle.
