The present study aimed to identify the main genetic, nutritional, and technological factors influencing the productive and reproductive performance of farm animals and to assess their relative contributions and interactions. A 12-month controlled comparative study included 480 clinically healthy animals, including 120 cattle, 160 pigs, and 200 laying hens of the selected breeds. Within each species and breed, eligible animals were grouped according to age, sex, physiological status, and body condition score. Animals with similar values for these variables were then matched and non-randomly allocated to control and experimental groups to minimize pre-intervention differences between the groups. In cattle, the assessed parameters included milk yield, milk fat and protein content, liveweight gain, pregnancy rate after first insemination, calf birth weight, and calf survival to weaning. In pigs, average daily gain, slaughter yield, intramuscular fat content, litter size, piglet birth weight, and pre-weaning survival were evaluated. In laying hens, egg production, egg weight, the proportion of eggs with shell or shape defects, hatchability, and chick survival were assessed. Measurements were obtained from July 2024 to June 2025 from production records, electronic weighing, infrared milk analysis, ultrasonography, Soxhlet extraction, and automated egg analysis. In cattle, genetic factors, particularly breed and breeding improvement, had the greatest influence in increasing milk yield by 5.8-9.3% and milk protein content by 0.08-0.12 percentage points. In pigs, nutritional factors made the greatest contribution, including optimization of the dietary protein-to-energy ratio, which increased average daily gain by 7.0%, litter size by 4.5%, and intramuscular fat content by 16.7%. In laying hens, combined nutritional and genetic factors increased egg production by 3.9-6.0% and reduced the proportion of non-standard eggs by 31.1%. Technological optimization of microclimate, stocking density, reproductive management, and stress reduction stabilized performance and increased piglet survival by 1.5-2.8%. The findings support species-specific integration of breeding, nutritional, and management strategies. © The Author(s) 2026.

The aim of the work was to evaluate the effectiveness of using microbial preparations and green manure cropsseparately and in combination to improve the condition of ordinary chernozem. Methods: The study involved a field experimentwith four treatment options: control; application of the “Azogran” biological preparation; green manure with a mixture of vetch andmustard; and a combination of these, and determination of the content of heavy metals in the soil and their biological activity.Results: The study found that the combined option provided the most positive changes: density decreased from 1.52 ± 0.03 to1.28 ± 0.02 g/cm3; the measured humus-related organic matter indicator increased from 2.1 ± 0.2 to 2.8 ± 0.1%; acidity changedfrom 5.8 ± 0.2 to neutral 6.7 ± 0.1; and the content of available, Chirikov-extractable phosphorus and potassium, reported asP2O5 and K2O, increased by 30.0 and 22.0%, respectively. Biological activity increased significantly: dehydrogenase activitydoubled, and basal respiration exceeded the control by 62.3%. It was also found that the concentrations of mobile forms of lead,cadmium, zinc and nickel decreased by 25.0–32.0%, which was accompanied by a 2.5-fold decrease in the phytotoxicity ofaqueous extracts. Conclusions: The data obtained demonstrate that the combination of the biological product with green manureresulted in synergistic improvements, simultaneously improving the physicochemical and biological properties of the soil andreducing the accumulation of metals. The practical significance of the study lies in confirming the possibility of using this approachas an affordable, environmentally safe and effective way to restore land damaged by military equipment. 2026-01-01T00:00:00Z https://dspace.mnau.edu.ua/jspui/handle/123456789/26864 Назва: Digital Marketing in Promoting Tourism and Other Services Автори: Pavlovska, Iryna; Стамат, Вікторія Михайлівна; Stamat, Viktoriia; Sogorin, Andriy; Voskresenska, Olena; Shepeleva, Olga Короткий огляд (реферат): The offered relevance structure is based on the rise of digital technologies in tourism and similar service industries where digital marketing determines demand development and competitive position of actors. The quick engagement of these digital tools in services advertising methodology brings forth naïve stereotypes and not any systematic intricate or quantitative study for long-term trend estimation. This highlights the need for a more in-depth understanding of digital behaviours and engagement patterns, use and effectiveness of digital marketing communications through internationally comparative data. The goal of the study is to reveal and measure development dynamics in application of digital marketing tools, activeness of consumers, and efficiency of digital-marketing communication (for tourism related service) based on international data during 2020–2024; the object is processes for digital marketing communication in service organizations. Methodological the research includes empirical quantitative analysis, descriptive methods, and comprehensive statistics for secondary and international comparative data during 2020–2024. It was concluded that the intensity of use of DM tools in tourism and related industries is increasing. Digital channels show stable growth, reaching a more even level after 2022. Consumer involvement analysis shows increased time devoted to digital content and online communication. Findings indicate greater exposure to digital marketing communications and engagement. Scientific novelty consists in the possibility to use established patterns for forming strategic directions for long-term development of tourism and service companies, including digital marketing. 2026-01-01T00:00:00Z https://dspace.mnau.edu.ua/jspui/handle/123456789/26815 Назва: Yield and energy efficiency of phytoenergy crops under biopreparation treatments in the conditions of the Southern Steppe of Ukraine Автори: Манушкіна, Тетяна Миколаївна; Manushkina, Tetyana; Корхова, Маргарита Михайлівна; Korhova, Margarita; Миколайчук, Віра Георгіївна; Mikolajchuk, Vira; Хоненко, Любов Григорівна; Honenko, Lubov Короткий огляд (реферат): In the current context of energy-resource shortages and increasing environmental pressures, the cultivation of phytoenergy crops is becoming particularly relevant, especially in regions with limited moisture, such as the Southern Steppe of Ukraine. The aim of the study was to determine the optimal species and varieties of energy crops, assess the effectiveness of biopreparations for increasing yield, and analyse the energy output of raw materials depending on cultivation technology. The methodology was based on field experiments using different crop species (Sorghum, Jerusalem artichoke, and cup plant), as well as biopreparations based on Bacillus megaterium, Trichoderma spp. and Azotobacter chroococcum. The results obtained showed that the highest yields were recorded in sorghum: Sudan grass (48.6 ± 1.2 t/ha) and sweet sorghum (46.8 ± 1.4 t/ha), whereas Jerusalem artichoke (38.4 ± 0.9 t/ha) and cup plant (32.6 ± 0.8 t/ha) lagged behind due to slower development in the first years. Combined treatment with biopreparations (Groundfix + Ekostern Trichoderma) provided a yield increase of up to 25.18% compared with the control, and sweet sorghum hybrid Verbliud achieved the maximum output of standard fuel equivalent (13.2 ± 0.4 t/ha) due to a high calorific value (4,120 kcal/kg). At the same time, raw-material moisture proved to be a key factor affecting energy efficiency. The conclusions confirm that the choice of crop, variety and biopreparation treatment is decisive for maximising energy output. The study’s practical value is found in its recommendations for farmers on how to best cultivate phytoenergy crops in arid environments, which will advance bioenergy production and lessen the anthropogenic burden on agroecosystems.
