The relevance of studying the microbiome of bull semen is due to the high importance of reproduction in animal husbandry, the problems of semen contamination with pathogens, and the need to improve the efficiency of artificial insemination. This review provides an overview of the taxonomic groups of microorganisms present in the seminal fluid of bulls. The review highlights the reasons for the limited research on the microbiota of bull semen and focuses on the advantages of modern molecular technologies, such as 16S rRNA sequencing, which allow for a more accurate determination of the microbial spectrum and their role in the reproductive system. The microbiota is diverse, including the phyla Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, and Fusobacteria, which are likely to have a variety of effects on seed quality and fertility. It has been proven that despite the established influence of the reproductive system microbiome on fertility and sperm quality, which has been confirmed by studies on humans and other species of productive animals, there are currently no specific scientific publications that examine in detail the role of the seminal microbiome in bulls and its impact on relevant reproductive indicators. This review explores the external factors that influence the composition of the microbiome, such as feeding, season, and animal management practices. It was concluded that the use of probiotics in the feeding of bulls is a promising and environmentally friendly way to optimize the microbiota and improve reproductive function, increasing the quality of semen and fertility and reducing the need for antibiotics.

This study investigated the effects of a feed additive containing potassium humate on hematological parameters in working dogs (n = 20) subjected to significant physical exertion. Such intense exercise can induce metabolic disorders, inflammatory processes, and endogenous intoxication, which negatively affect erythrocyte function, blood rheology, and tissue oxygenation. Humic acids, known for their antioxidant, detoxifying, and hemostasis-modulating properties, were administered at a dosage of 25 mg daily for 21 days as a supplement to the main diet. Hematological analysis, performed using an analyzer and phase-contrast microscopy, revealed significant improvements in hematological parameters: an 18.2% increase in red blood cell count, a 16.8% increase in hemoglobin levels, and a 17.7% improvement in the Mean Corpuscular Hemoglobin Concentration (MCHC). Morphological changes in erythrocytes included a 100% increase in normocytes relative to the baseline value, as well as reductions in microcytosis (25.0%), hypochromia (14.3%), echinocytosis (30.0%), and spherocytosis (50.0%). These data indicate an enhanced oxygen transport capacity, improved erythrocyte morphology, and a decreased number of pathological cell forms. No adverse reactions were detected during the experiment. This study demonstrates the efficacy of humic acids in stabilizing hematological parameters and improving erythrocyte function in dogs under heavy physical loads.

The purpose of this study was to evaluate the effect of testosterone levels in withers hair on the productive qualities and meat productivity of Hereford bulls (n = 60).

According to hormone levels, the animals were divided into three groups: low, medium and high testosterone. Testosterone concentration was measured by ELISA after hormone extraction from hair. The weight gain, slaughter parameters, and morphological and chemical composition of the carcasses were evaluated. Statistical analysis was performed using the Student’s t-test.

The results showed a pronounced positive relationship between testosterone levels and growth rate. Bulls with high hormone levels significantly outperformed animals with low levels in terms of absolute (by 23.1%) and average daily (by 23.1%) weight gain, carcass weight (by 10.2%) and pulp weight (by 11.1%). At the same time, there was a significant decrease in internal fat deposition (by 0.4%) and an increase in protein content (by 1.1%) in the longest muscle. Thus, the determination of testosterone in hair is a reliable tool for predicting meat productivity and can be used in breeding work to select animals with optimal hormonal status.

Relevance. An analysis of the structure of the breeding stock, including the selection method for breeding Holstein cattle, revealed a large number of cows obtained as a result of inbreeding, the degree of which will increase over time.

Methods. The object of the study is repair heifers and cows born in 2018, divided into groups according to the type of selection – heterogeneous selection (outbreeding) and homogeneous selection (moderate and long–term inbreeding). The material and data for comparison were the database of the IAC “SELEX-Dairy Cattle”, the results of our own research. Milk yield for 305 days of lactation was taken into account according to control milks, MJ and MDB in milk.

Results. The majority of cows were obtained as a result of the use of remote inbreeding — more than 65.0%. Cows obtained by heterogeneous (unrelated) selection turned out to be only 12.4%. Cows with the highest productivity rates were found in the second lactation — 10484±135.86 kg (13.8%), which was 1450 kg more than in the first heifers and 169 kg (1.6%) in the third lactation. Further, there was a slight decrease in milk yield by 16 kg and 301 kg, respectively, or by 0.15% and 2.9%. Cows obtained as a result of a moderate degree of inbred had the best indicators. They outperformed animals from other groups by 559 kg, or 5.46% (outbred) and by 268 kg, or 2.62% (distant inbreeding). In animals obtained as a result of outbred selection and moderate inbreeding, there is a gradual decrease in the ratio from the maximum for the first to the minimum for the last (fourth) lactation. In cows with distant inbreeding, the ratio of fat and protein in milk decreased sharply after the second lactation.

In the Leningrad region, regardless of the norm and frequency of use, high biological efficacy of drugs (83.7–100%) against powdery mildew, brown rust and mottling (dark brown and septoria pyrenophorosis) of leaves was noted. In the Saratov and Volgograd regions, a different trend was observed against brown rust and powdery mildew. The advantage was due to the two-fold use of drugs, while the most acceptable drug was “Soligor, CE” at the rates of 0.4 + 0.6 l/ha and 0.4 + 0.8 l/ha. The effectiveness of the drug “Falcon, CE” against powdery mildew was 81.3–100%, and “Soligor, CE” in the above-mentioned regulations was 70.1–93.3%. Double treatments with these three-component fungicides were 74–93.3% effective against brown rust. In terms of the mass of 1,000 grains and the mass of grain per ear in all regions where the biological efficacy of “Falcon, CE” and “Soligor, CE” preparations was studied, the advantage was for their double use. The double use of the drug “Falcon, CE” allowed to save from 8.8 to 38.3% of the crop, and the fungicide “Soligor, CE” — from 10.2–27.5 to 11.6–32.5% at application rates of 0.4 + 0.6 l/ha and 0.4 + 0.8 l/ha. According to the toxic load, both drugs are classified as moderately dangerous. With a close indicator of the hazard coefficient for bees (1.94–3.89), the environmental load of the drug “Falcon, CE” (11,963.43 units) was higher than that of “Soligor, CE” (1839.1–3677.2 units).

The article is devoted to the effect of the organic fertilizer “EcoTerra-T” on the agrochemical properties of dark gray forest soil. The research was carried out on crops of spring wheat (Tríticum aestívum L/) of the Watan variety. The bioactivated organic fertilizer «EcoTerra-T» under study, obtained by fermentation of bird droppings, was applied in various doses: 1) 1 t/ha; 2) 2 t/ha; 3) 3 t/ha; 4) 4 t/ha; 5) control (without application). The studied soils of the experimental site are characterized by a slightly acidic reaction of the medium, a fairly high humus content in the humus-accumulative horizon. When using organic fertilizers, there is a tendency to increase the organic matter content by 0.1% (in variants with 1 t/ha and 2 t/ha) and 0.2% (in variants with 3 t/ha and 4 t/ha). Fertilization contributed to an increase in the nutrient content in the soil to the level of “very high” in phosphorus and “high” in potassium and nitrate nitrogen. The supply of ammonium ion to the soil increased from the “very low” level to the “low” level when applying the studied fertilizers. With an increase in the dose of organic fertilizer, the yield increases to an average of 30%, the nitrogen content to 43%, phosphorus to 11%, and potassium to 28% in the soil. The most pronounced effect is observed in variants with 2–4 t/ha.

Relevance. For the successful development of animal husbandry, field forage production is an essential factor. Under the challenging weather and climatic conditions of the Republic of Tyva, a comparative study of the yield and quality of green mass of maize hybrids is of particular importance. The objects of research were the domestic hybrids Koryfey (St), Ross 140 sv, KS 178 sv, Ross 199 mv, Ross 130 mv, KR 194 mv, and the ultra-early hybrid population Rossiyskaya 2.

The aim of the study was to identify maize hybrids with the highest yield and to determine the optimal sowing dates.

Methods. The establishment and implementation of the field trial were carried out in accordance with the requirements of the Methods of State Variety Testing of Agricultural Crops and commonly accepted methodological recommendations for conducting maize field trials. Statistical analysis was performed according to B.A. Dospekhov.

Results. In a two-factor field experiment on dark chestnut light loamy soils under arid and highly arid vegetation periods (HTC 0.45–0.77), it was revealed that the green mass yield of all maize hybrids, except KS 178 sv, exceeded that of the zoned hybrid Koryfey. The optimal sowing dates were early (10 May) and medium (21 May). The highest green mass yield (65.3–66.5 t/ha) was obtained from the hybrid population Rossiyskaya 2, which was also characterized by a relatively high output of dry matter (22.2–22.9 t/ha), metabolizable energy (263.9–275.0 GJ/ha), the highest accumulation of digestible protein (944.9–976.6 kg/ha), and its supply per feed unit (36.6–42.6 g). In terms of yield and the complex of nutritional value indicators, along with the hybrid Koryfey and the hybrid population Rossiyskaya 2, the hybrids Ross 199 mv, Ross 130 mv, and Ross 140 sv are recommended for cultivation in the conditions of the Republic of Tyva.

Environmental pollution with heavy metals, including xenobiotic elements with high cumulative characteristics, is currently an urgent problem. Lead is a priority pollutant of the first hazard class that enters the environment through fertilizers and as a result of technological emissions (dust, vapors, solutions), which easily settle on soil and water surfaces.

Soil microorganisms of the genus Bacillus spp. with high accumulation characteristics can be used as effective sorbents of mobile forms of toxic elements. The paper presents results of experimental studies on the isolation and evaluation of the effectiveness of Bacillus spp. strains isolated from territories with high anthropogenic load. The use of the well diffusion method in combination with the serial dilution method, as well as the “replica” method with seeding on substrates with high cationic load by adding Pb(NO₃)₂ “P.A.” in concentrations of 0.031 M, 0.016 M and 0.008 M allowed isolation of a promising B. licheniformis RZn strain characterized by stable growth on media with Pb(NO₃)₂ addition at a concentration of 0.031 M and lead cation sorption rates from the substrate up to 65.39%. In a model experiment using test cultures of Sinapis alba L. and Triticum aestivum L., a reduction in the toxic effect of lead on germination rates as well as plant morphometric parameters was observed. This indicates the significant biological potential of the studied strain as a remediator of lead ions.

The objects of the study were trees of the Veteran and Orel striped apple varieties and the biostimulator organomineral fertilizer “Biostim Universal”, containing N (total) 6.0%, K2O 1.3%, SO3 5.0% and free amino acids of plant origin 10.0%. Leaf top dressing was carried out 4 times per season with an interval of 14 days, starting from the second decade of May. The experimental scheme included 4 options: 1st — control (without treatment); 2^nd–4^th — spraying of trees with agrochemicals with consumption rates of 3, 5 and 7 l/ha. The repetition of the experiment is threefold, with 5 trees each. The increase in the diameter of the Orlovskoye striped strain by the end of the growing seasons of 2024 and 2025 was the maximum for the “Biostim” variant of 5 l/ha — 49.3% and 34.9%, respectively. According to the Veteran variety, 53.5% in 2024 for the “Biostim” variant of 5 liters/ha and 41.9% in 2025 for the “Biostim” variant of 7 l/ha. The winter variety Veteran revealed more stable values of biometric indicators for the variants, regardless of the formative pruning, weather conditions during the research years and the consumption rate of the drug. In the autumn variety Orlovskoye striped, an increase in the dosage of the drug to 7 l/ha in the arid conditions of 2024 with elevated temperatures in the summer months had a negative impact on crown formation. In 2025, in conditions of sufficient moisture supply in this variant, the trees recovered, the increase in crown diameter relative to 2024 was the maximum — 102.9%. According to a set of biometric indicators, higher and more stable values were obtained with leaf top dressing with “Biostim Universal” agrochemicals of 5 l/ha.

Relevance. As a strategically important area of the agro-industrial complex and providing the food base for agriculture, crop production is highly dependent on natural and climatic factors, the seasonal nature of reproduction cycles and vulnerability to land degradation. These features, aggravated by climate change and external economic constraints, necessitate the formation of new organizational and economic mechanisms capable of ensuring the sustainability and further development of the industry. One of these mechanisms is clustering, which makes it possible to integrate production, processing, logistics, scientific and managerial links into a single system that creates a synergistic effect, strengthens competitive advantages and creates prerequisites for long-term development.

Methods. The methodological basis of the research is the dialectical approach, monographic, analytical, abstract-logical and comparative methods, structural-logical and economicstatistical analyses.

Results. The institutional and substantive characteristics of crop clusters are revealed, key features (seasonality, long reproduction cycle, territorial localization, innovation orientation, social significance, public-private partnership) are highlighted. Based on the analysis of foreign experience, five management models for the development of agricultural crop clusters have been identified. As a result, the authors proposed an organizational and crop cluster based on the example of the Perm Region, including a coordinating council, a cluster development center, a network of feed centers and auxiliary infrastructure. The model focuses on the involvement of unused land, the introduction of adaptive agricultural technologies and the development of export potential. Its implementation will ensure an increase in the efficiency of agricultural production, reduce logistical costs, create jobs and strengthen the tax base, which confirms the importance of the cluster approach for the development of the regional agro-industrial complex.

Relevance. The article presents a structural analysis of the white wine market in Russia in the period 2020–2024. The key regions of viticulture, the classification of white grape varieties, the typology of wines by physique and the level of sweetness, as well as the features of distribution channels are considered. Based on the results of the study, the key factors determining the growth trajectory and competitiveness of the domestic segment of white wine have been identified, which makes it possible to consider this industry as strategically important for the Russian agro-industrial complex.

The purpose of the article is to conduct the first comprehensive structural analysis of the Russian white wine market.

The scientific novelty of the research lies in the systematic classification and interpretation of the structure of the Russian white wine market, taking into account internal regional specifics, consumer trends and government policy factors.

Methods. Within the framework of this study, both quantitative and qualitative analysis methods have been applied, providing an integrated approach to assessing the structure and dynamics of the development of the white wine market in Russia. The study used methods of statistical analysis, content analysis and a comparative approach.

Results. The key factors influencing the development of the Russian white wine market were highlighted: government support measures, the transformation of consumer preferences towards light and organic wines, competition with imported products, as well as the development of enogastronomical tourism as a tool for regional promotion. The Russian market demonstrates both compliance with global trends and unique features: strengthening the role of autochthonous grape varieties, strengthening the position of local brands and increasing the share of domestic wine in the consumption structure.

Introduction. Ensuring human resources for the regional agro-industrial complex amid the industry›s technological modernization is gaining strategic importance for the country›s food security. The proportion of young employees in agriculture accounts for only 9% of the total workforce, necessitating urgent measures to attract youth to the sector. Rural schools are a key partner for agribusiness enterprises and possess the potential to become an integral part of the agro-industrial complex ecosystem for career guidance and training of future personnel.

Methods. The study was conducted in 2025 and encompassed all federal districts of the Russian Federation. The methodological framework consisted of a survey of teachers from general education schools and centers of supplementary education (n = 1462), including those from rural areas (n = 320).

Results. The findings reveal that teachers in rural schools have insufficient knowledge of regional and local staffing needs, potential investment projects, centers of advanced competencies, opportunities for partnership with industry enterprises, as well as career guidance methodologies. Despite a pressing need, collaboration with employers is nonsystemic in nature. Recommendations are provided for organizing partnerships between schools and agro-industrial enterprises, including within the framework of the Ministry of Agriculture’s “Agro-tech Classes” project.
