Optimising nutritional profiles to enhance fertility in domestic rabbits

Nazariy Fedynyshyn

Domestic rabbits often flourish on paper yet falter in the nest box-a quirk that pushes nutritionists to chase subtler levers than plain calorie counts. Methodology – This critical narrative review homed in on just twelve peer-reviewed, controlled experiments published between 2015 and 2025 that isolated dietary composition as the principal driver of reproductive change. Titles were screened with PRISMA logic, full texts double-read, and outcomes plotted in a triplex grid linking lipid class, phytonutrient density, and microbial adjuncts, when studies shared endpoints, random-effects modelling sketched pooled tendencies. Findings – Enriching rations with a modest 2 % long-chain n-3 polyunsaturated fatty acids nudged conception probability upward by roughly eleven per cent, while kits from does fed folate-fortified roughage finished weaning sixty grams heavier-a gain small on the scales yet large in farm arithmetic. Phytogenic boosters such as Moringa oleifera leaf or date-palm pollen sharpened antioxidant tone, a biochemical echo that mirrored lower early-embryo loss across five of the twelve trials. Postbiotic blends quietly stole the spotlight under summer heat: mortality in treated litters halved without any jump in feed intake, hinting that microbial signalling can trump pure energy balance when mercury climbs. Gaps glare, though. Nine studies spanned only a single reproductive cycle, buck fertility received little more than a footnote, and cost-per-kit surfaced in barely a couple of spreadsheets. Conclusion – The evidence converges on one, stark takeaway: rabbit fertility improves not by feeding more, but by feeding smarter-fine-tuning fatty-acid ratios, vitamin cofactors, and bioactive plants so endocrine, oxidative, and microbial cues sing in harmony. While multi-cycle, sex-balanced trials remain overdue, backyard keepers needn’t wait: swap a slice of starch for flaxseed, stir in a pinch of Moringa, and watch the numbers tick north.

Digital tools play an important role in ensuring the sustainable development of the agricultural sector. In the context of organic farming, which is based on environmental responsibility, biodiversity conservation and rational use of natural resources, the use of digital technologies opens up new approaches to management, strengthening the sustainability of agricultural systems and introducing modern innovations. Against the background of such global problems as climate change, soil depletion and growing demand for environmentally friendly products, the digital transformation of organic agriculture is becoming increasingly significant. The digital transformation of the agricultural sector of Ukraine is considered a key stage in its evolutionary development, which is focused on achieving a number of strategically important goals. One of the main priorities is to increase the efficiency of production processes and the overall productivity of the industry. The integration of innovative digital solutions, including blockchain technologies and complex observation systems, creates new opportunities for ensuring the quality and safety of agricultural products. This allows for full control over all stages of the production chain – from cultivation to consumption, ensuring transparency and trust on the part of the end consumer.
In addition, the introduction of electronic platforms and digital trading tools creates additional opportunities for agricultural producers to enter new markets – both within the country and abroad. Such a strategy contributes to expanding the export potential of the agricultural sector and increasing its integration into the global economic system. In this context, digital technologies are not only a means of technological renewal, but also an important factor in increasing the competitiveness of domestic agricultural production.

Influence of soil temperature on the growth and development of bean plants at different sowing dates in the conditions of the Right-Bank Forest-Steppe of Ukraine

O. Ovcharuk — 2025-05-16

Soil and air temperature enable the bean root system to absorb nutrients, increase the intensity of photosynthesis and plant respiration, transpiration and other physiological processes. The temperature at which plants grow and develop most intensively is optimal, and deviation from it slows down growth and development. The optimal temperature promotes the active process of photosynthesis, while assimilation prevails over dissimilation, as a result of which dry matter accumulates in plants. Temperature fluctuations negatively affect the growth and development of bean plants and often lead to their defeat by diseases. As the temperature increases, the processes of assimilation and synthesis of organic substances intensify, while the intensity of respiration increases. It should be noted that bean plants of early sowing dates will always be better developed than those sown later, and will have higher productivity. This can be explained by the fact that at early sowing dates (at lower temperatures), although plant shoots appear somewhat later, their root system develops better compared to plants sown later. Such shoots respond more easily to short-term droughts, and plants form a greater yield. At later sowing dates (when the soil temperature is higher), shoots appear faster, and accordingly the root system develops more intensively and the vegetative mass increases. This leads to a disruption of the balance between the root system and the leaf apparatus in providing bean plants with moisture, as a result of which in hot, sunny weather the leaves wither, stress is observed and plant productivity decreases. The effect of temperature on the growth and development of bean plants also depends on their physiological state and the action of other factors. With an increase in the intensity of sunlight with a sufficient content of moisture and nutrients in the soil, the intensity of photosynthetic activity of plants and other physiological processes of plants increases

The role of sewage sludge masses in expanding the range of organo-mineral fertilizers

V. Dubovyi — 2025-05-16

The article examines the prospects and technologies for the use of sewage sludge masses (SSM) in agriculture, as well as the environmental and economic aspects of their utilization. It highlights potential risks associated with the presence of heavy metals and pathogenic microorganisms, which may pose threats to the environment and human health. The paper provides an analysis of current approaches to the processing and utilization of sewage sludge, aimed at reducing environmental impact. A review of current regulatory frameworks governing the use of sewage sludge in Ukraine and other countries is presented. Based on the research findings, the paper emphasizes the feasibility of scientifically justified application of SSM as an economically viable and environmentally acceptable resource in sustainable agriculture systems. An agrochemical analysis of SSM from sedimentation maps (wet) and dry storage (heaps) was conducted. It was shown that the concentration of heavy metals does not exceed maximum permissible limits. The importance of using SSM in the cultivation of cereal crops (wheat and barley), legumes (soybean), pseudocereals (buckwheat), and industrial crops (sunflower, corn for grain) is noted, which corresponds with the focus of our research.

Optimization of plant physiological status as a basis for environmentally safe agricultural production

N. Karachynska — 2025-05-16

This study examines the optimization of plant physiological status as a mechanism for reducing environmental risks in agroecosystems. A model is proposed based on the stepwise optimization of the metabolic activity of agro-phytocenoses, which ensures a reduction in environmental risks. It is shown that effective interaction between plant metabolic activity, the state of soil microbiota, and abiotic environmental factors forms the basis for enhancing plant tolerance to stress conditions. The importance of phased activation of signaling and metabolic cascades in regulating plant physiological status is demonstrated, involving mineral nutrition, biostimulants, and symbiotic organisms. It is emphasized that the biosynthesis of biologically active phytocompounds (secondary metabolites) not only performs protective functions (anti-pathogenic, anti-stress) but also acts as a mediator of trophic and regulatory interactions in the rhizosphere. It is proven that the regulation of the biosynthesis of such compounds plays a decisive role in maintaining plant viability under unfavorable conditions and minimizing ecological risks associated with soil degradation, the spread of phytopathogens, and the decline of agrobiodiversity. The proposed integrated approach to managing plant physiological status, which advances J. Kempf’s “plant health pyramid” concept, enhances the energetic efficiency of plant functioning, increases yield and resilience, and actively contributes to soil regeneration. This makes healthy plants a key factor in regenerative agriculture, enabling the implementation of environmentally safe agrotechnologies for building sustainable agroecosystems. Abiotic stresses (temperature, water regime, CO2 concentration, light, etc.) increase plant susceptibility to pathogens and pests. The study highlights the potential of leveraging natural mechanisms for developing such agrotechnologies through the integration of biotechnological and agroecological solutions aimed at enhancing the adaptability and stability of agroecosystems, ensuring sustainable crop productivity, and reducing anthropogenic pressure on the environment.

Radionuclide contamination of rivers in Zhytomyr Polissia: analysis of bioaccumulation in hydrobionts

R. Makhinko — 2025-05-16

The objective of this study was to conduct a comprehensive radioecological assessment of aquatic ecosystems in Zhytomyr Polissia during the remote period following the Chornobyl Nuclear Power Plant accident, with detailed determination of radionuclide contamination levels in bottom sediments, water, and commercial fish species, as well as analysis of bioaccumulation patterns of radiocesium and radiostrontium in hydrobionts. The research was conducted in January 2025 on water bodies within the Teteriv River basin in Zhytomyr Oblast using modern radiochemical and gamma-spectrometric analytical methods. Samples of bottom sediments from depths of 0.5-1.0 m, surface layer coastal sediments (0-5 cm), and water from the Teteriv River within Zhytomyr city were collected and analyzed, along with samples of muscle tissue and the “head + internal organs” complex from four commercial fish species (silver carp, common carp, Prussian carp, northern pike) from the Zdvyzh River in Brusyliv district. Determination of specific activity of radionuclides 137Cs, 90Sr, and natural 40K was performed in the accredited measurement laboratory of Polissia National University with measurement error not exceeding 15-20% at a confidence probability of 0.95. Significant differentiation of radionuclide concentrations between different components of the aquatic ecosystem was established. The highest concentrations of 137Cs are observed in bottom sediments (25.81 Bq/kg) and coastal sediments (20.26 Bq/kg), which is 71.7 times higher than water indicators (0.36 Bq/kg). Concentrations of 90Sr are characterized by the opposite pattern with maximum values in coastal sediments (8.60 Bq/kg) due to the higher mobility of this radionuclide. Among the studied fish species, the highest 137Cs content was recorded in cyprinid species: carp (3.16-5.45 Bq/kg), silver carp (2.51-4.76 Bq/kg), and the lowest in pike (1.53-3.17 Bq/kg) and Prussian carp (0.95-2.05 Bq/kg). Concentrations of 90Sr in fish tissues ranged from 12.90 Bq/kg in pike to 26.30 Bq/kg in silver carp, which is 2-4 times higher than background values for the region. The identified species-specific bioaccumulation of radionuclides is related to the peculiarities of feeding behavior, ecology, and physiology of the studied species. Concentrations of 137Cs and 90Sr in fish muscle tissue do not exceed current hygienic standards for food products; however, elevated levels in internal organs require their mandatory removal during processing. Concentrations of the natural radionuclide 40K in bottom sediments and fish tissues correspond to literature values for the region. The results demonstrate the necessity of continuing systematic radioecological monitoring of aquatic bioresources in the region and developing scientifically based measures to minimize radioecological risks to ensure safe utilization of aquatic ecosystems in Zhytomyr Polissia

Bioecological and energy potential of Robinia pseudoacacia L. stands under the conditions of the Vinnytsia Forestry District of SE «Forests of Ukraine»

S. Razanov — 2025-05-16

The scientific work presents the results of a comprehensive study of the productivity and ecological role of Robinia pseudoacacia L. plantations in Vinnytsia region. The relevance of the study stems from the widespread use of this species in agroforestry, energy forestry, and the reclamation of degraded lands, due to its high ecological plasticity, ability to fix atmospheric nitrogen, and rapid biomass growth. A review of the literature demonstrates the ambivalent impact of Robinia pseudoacacia L.: on the one hand, it improves soil fertility and increases nitrogen content; on the other hand, it poses a risk of displacing native plant species and disrupting the hydrological regime of the area. Fifteen temporary test plots with a total area of 5.25 hectares were established within the Vinnytsia Forestry Branch. Plot selection was carried out based on forest site conditions, stand age, species composition, site quality, and sanitary condition. The data collection methodology followed the national standard SOU 02.02-37-476:2006, ensuring the representativeness and reliability of the obtained data. The results of the study indicate the high biological productivity of Robinia pseudoacacia plantations within the Vinnytsia Forestry District. The predominant forest site conditions were fresh loams (type C2), which provided optimal conditions for the growth of this species. The age structure of the plantations is characterized by the dominance of young and middle-aged stands (over 56%), indicating active regeneration dynamics. Maturing, mature, and overmature stands accounted for a smaller proportion, reflecting effective forest management practices. The silvicultural and mensurational characteristics revealed significant variability in stand parameters depending on age. The average tree diameter ranged from 3.7 cm in 4-year-old stands to over 27 cm in 82-year-old stands, while tree height varied from 4.2 to 24.5 m. Absolute stand density ranged from 1.24 to 44.71 m²/ha, and relative density from 0.22 to 1.09, indicating different developmental stages and stand densities. Owing to the high wood density and calorific value, the stands exhibit considerable potential for biomass production as a source of renewable energy. The assessment of phytomass across different fractions of the aboveground tree components enabled an objective estimation of accumulated biomass per unit area and the calculation of potential energy yields. Structural analysis of sample plots by site quality classes revealed a predominance of medium-quality stands (classes I and III), characterized by an optimal balance between growth and ecosystem stability. This creates promising prospects for the further use of Robinia pseudoacacia L. in regional forestry practices as a key tool for bioenergy development and forest reclamation of degraded lands

Formation of econetworks in the context of the impact of inorganic pollutants

S. Sovhira — 2025-05-16

The article presents the results of a comprehensive study focused on assessing the impact of inorganic pollutants on the formation of an ecological network in the Central Pobuzhzhia region (Ukraine). The necessity of incorporating spatial distribution of chemical pollution into ecological network planning-particularly in the development of ecological corridors, buffer zones, and core natural areas-is substantiated. The study includes an analysis of heavy metal concentrations (lead, cadmium, zinc, copper, nickel) in soils, bottom sediments, and above-ground plant biomass. Concentrations of nitrates and phosphates in rivers and ponds were also evaluated to determine their impact on aquatic organisms, zooplankton, benthos, and fish. It was found that inorganic pollution leads to disruptions in soil microbiological activity, degradation of biota, simplification of ecosystem structures, and active bioaccumulation of toxicants in organism tissues. In areas with intense anthropogenic pressure, species richness of phytocenoses decreased by 40-50%, chlorophyll content in model plant species was significantly reduced, and enzymatic activity in soils was suppressed. GIS analysis helped identify spatial conflict zones between projected elements of the ecological network and pollution hotspots. Based on the findings, practical recommendations were developed for adapting ecological network schemes in anthropogenically transformed landscapes. These include soil remediation (phytoremediation), the establishment of riparian buffer zones, rerouting ecological corridors to more stable areas, and implementation of long-term environmental monitoring. The results presented in this study have both theoretical and practical significance for nature conservation planning, restoration of degraded ecosystems, and sustainable spatial development of polluted regions
