Aliakbar Solhjou, Sayed Mansor Alavimanesh

Res. Agr. Eng., 2023, 69(2):85-93 | DOI: 10.17221/41/2022-RAE

Tillage operations in dry soil conditions have increasingly been used in Iran in recent years. However, due to the recent droughts, the choice of suitable implements to reduce the clod and draught force is still under investigation. This study was aimed at determining the effect of the geometry of a bent leg tillage implement on the soil pulverisation and draught force in dry soil conditions. The treatments included three bent leg tillage depths (10, 15, and 20 cm) and three forward speeds (6, 9, and 12 km·h–1). The effect of the bent leg tillage implement on the clod mean weight diameter (MWD) and draught force was studied using a split plot experiment with three replications. The results showed that the tillage depth and forward speed affected the MWD and the draught force. Increasing the tillage depth from 10 to 20 cm increased the MWD and draught force by 24.9 and 35.1%, respectively. Increasing the forward speed from 6 to 12 km·h–1 decreased the MWD by 7.4% and increased the draught force by 40.0%. These findings show that the bent leg tillage technology has the potential to reduce the MWD and draught force at higher forward speeds. Therefore, a bent leg tillage implement can be suggested as a proper implement for tilling in dry land conditions.

Cereal and legume grains are germinated to improve their nutritional and sensory qualities. This study investigated the effect of germination on the physicochemical properties of some grains and legumes grown in Türkiye. At the end of the germination for 48 h and 96 h at 24 ± 1 °C, carbohydrate, protein, lipid, dietary fibre, dry matter, ash, total phenolic content, antioxidant capacity and colour analyses of the germinated grains were determined. The results indicated that the germination process increased the phenolic content of all samples. The legume seeds' 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity significantly increased with germination. The germination process significantly decreased the total carbohydrate contents of the samples. A statistically significant decrease was found for the protein content of barley and corn, especially by 48 h of germination. The lipid content of cereal grains decreased as germination progressed. It might be recommended to improve the functional properties of cereals and legumes by germination and their use in the food industry.

Lymantria dispar, a well-known defoliating pest species, also presents a health challenge due to the allergenic potential of its hairs, making it interesting to study from various perspectives. As chemical control methods decline in popularity, the search for effective natural enemies of this pest, such as predators, parasites and parasitoids, are expanding. On this occasion, we report the discovery of the primary parasitoid Glyptapanteles liparidis and the secondary parasitoid Gelis areator for the fauna of Slovenia. Illustrations and a short biology are given for both species.

Czech J. Anim. Sci., 2023, 68(9):383-390 | DOI: 10.17221/4/2023-CJAS

This study was conducted to determine the individual types of crystallisation structures of cervical mucus (arborisation phenomenon) in sheep and changes in the types of these structures during oestrus. A total of 80 ewes aged between two and eight years were included in the study. Oestrus synchronisation was performed using intravaginal sponges, and samples of cervical mucus were collected 55–57 h after the removal of intravaginal sponges and subsequently evaluated. The crystallisation structures of the cervical mucus of sheep exhibit the same sequence during oestrus as in cattle. The most frequently occurring types of crystallisation in the observed sheep included twig-shaped (33.33%), twig-shaped-clubmosses (24.00%) and clubmosses (14.67%). The least common type was fern frond crystallisation (1.33%). A statistically significant difference was found between the representation of individual types of crystallisation (< 0.01). As with cattle, it is possible to use the evaluation of the crystallisation of cervical mucus to determine the optimum time for insemination, especially in groups of animals with previous synchronisation/induction of oestrus. Establishing the correct time for insemination or natural mating with a ram makes it possible to optimise breeding management and improve pregnancy rates, which are crucial in breeding these seasonally polyoestrous animals. Based on the results, it can be stated that insemination should take place 57+ h after the removal of intravaginal sponges and the application of hormonal treatments for oestrus induction and synchronisation (equine chorionic gonadotropin).

Vet Med - Czech, 2023, 68(1):11-16 | DOI: 10.17221/106/2021-VETMED

The purpose of the study was to evaluate the occurrence and range of refractive errors in dogs of different ages. A total of 99 clinically healthy, mixed-breed mesocephalic dogs were included in the study and divided into three different age groups according to the current human/pet analogy chart: 40 adults (23 males, 17 females, 1–8 years old, 3–70 kg), 21 seniors (14 males, 7 females, 6–11 years old, 7–42 kg), and 38 geriatrics (22 males, 16 females, 8–13 years old, 5–45 kg). All the dogs underwent an ophthalmic examination, including Schirmer tear test, tonometry, biomicroscopy, and ophthalmoscopy. Neither eye drops nor pharmacological sedatives were administered before the autorefractometry. The refractive states were assessed bilaterally using a hand-held Retinomax 3 (Righton) autorefractor. The results underwent statistical analysis using Statistica v12 software (ANOVA and t-test). A P-value < 0.05 was considered as significant. Emmetropia, defined as a refractive state > −0.5 D and < +0.5 D, was found in 36% of the adult, 43% of the senior, and 38% of the geriatric patients. Anisometropia was found in 1% of the adult, 9.5% of the senior and 5.5% of the geriatric dogs when the refractive power of the two eyes differed ≥ 1.0 myopia ≤ −0.5 D and hyperopia ≥ +0.5 D were found in 23% and 41% of the adult eye globes as well as 24% and 33% in the senior dogs and 15% and 47% in the geriatric dogs, respectively. The maximal values of the myopia in the adult and geriatric dogs were −2.5 D and −2.75 D, respectively. The maximal values of the hyperopia in the adult and geriatric dogs were 1.75 D and 2.5 D, respectively. No statistically significant correlation was found between the groups. Ametropia is a common refractive state for dogs of different ages. The most frequent refractive state in ametropic mixed-bed dogs in all age groups is hyperopia.

Vet Med - Czech, 2023, 68(11):419-427 | DOI: 10.17221/65/2023-VETMED

The aim of this study was to map the spectrum of microorganisms belonging to the genus Acinetobacter in domestic animals with a specific focus on the prevalence of Acinetobacter pseudolwoffii. Additionally, the susceptibility of isolates to antimicrobial agents was determined. In the period from January 1, 2014, to August 31, 2015, a total of 9 544 samples originating from gross lesions and pathological processes of animals exhibiting clinical symptoms of the disease were examined across 41 districts in the Czech Republic. The examinations were carried out using culture methods involving meat-peptone blood agar and Endo agar under aerobic conditions at a temperature of 37 ± 1 °C for 18–24 hours. Isolates were confirmed using molecular phenotypic method MALDI–TOF MS with the MBT Compass Library Revision L 2020 covering 3 239 species/entries (9 607 MSP) from Bruker Daltonics company. Out of the 108 isolates (prevalence 1.13%), 14 species of Acinetobacter spp. were identified, with 5 isolates remaining unclassified as species. A. pseudolwoffii was the predominant species isolated in 25 cases (prevalence 0.26%). Antimicrobial susceptibility was determined for 12 antimicrobials by the disc diffusion method, with A. pseudolwoffii isolates exhibiting the lowest susceptibility to ceftazidime (32%) and co-trimoxazole (60%).

This work aims to differentiate the rural land of Slovakia in view of the possibility of effective sunflower growing. The differentiation is based on pedo-climatic and production-economic parameters. Soil categorisation took into account the correlation between the site properties (soil and climatic conditions) and the biological and agrotechnical requirements of the crops. Sunflower requirements were included in yield databases using software filters such that a given site property excluded or limited sunflower growing, which was reflected in predicted production. The prediction was subsequently interpolated into four suitability categories: soils unsuitable for sunflower growing, less suitable soils, suitable soils and very suitable soils. A map of categories of soil suitability for sunflower growing was created using a Geographic Information System on the distribution of soil parameters in Slovakia. According to our calculation in Slovakia, 18.8% of farmland is very suitable for sunflower growing, 24.9% is suitable, 16.6% is less suitable, and 39.7% is unsuitable for sunflower growing. These categories are characterised and specified in detail in the paper in terms of geographical, soil, climatic, production and economic parameters. The analysis of the actual sowing of sunflowers between 2018 and 2021 showed that 51% of the areas were located in very suitable soils, 32% in suitable, 10% in less suitable soils and 7% in unsuitable soils for cultivation.

Jaroslav Valenta, Darina Chodová, Eva Tùmová, Mohamed Ketta

Czech J. Anim. Sci., 2022, 67(7):286-294 | DOI: 10.17221/91/2022-CJAS

The aim of the present study was to compare carcass characteristics and meat quality of fast- (Ross 308), medium- (Hubbard JA757) and slow-growing (ISA Dual) chickens (n = 1 980). When the chickens reached an average live weight of 2 kg, 40 birds (males to females, 1 : 1) of each genotype were randomly selected and slaughtered for carcass analysis. Pectoralis major (PM) muscle samples were taken to determine the physical and chemical parameters of the meat quality. The fast- and medium-growing genotypes had higher (+3.24% and +3.84%, respectively) dressing out percentages than the slow-growing chickens. As expected, the breast percentage significantly decreased in the order of fast growth > medium growth > slow growth. The abdominal fat percentage was the lowest in Ross 308 chickens, but the abdominal fat percentage in JA757 and ISA Dual chickens did not differ. For edible organs, fast- and medium-growing chickens had heavier hearts and livers than slow-growing chickens. In contrast, ISA Dual chickens showed heavier gizzards. Genotype dramatically affected the chemical composition of PM muscle. The ISA Dual chickens exhibited a significantly higher proportion of dry matter and protein and lower ether extract and cholesterol content than Ross 308 chickens, with intermediate values for JA757 chickens. The ISA Dual group had a lower ash content than Ross 308 and JA757 groups. In terms of physical parameters, the ISA Dual chickens had higher lightness and yellowness and lower redness, pH 24, and cooking loss than those of the other genotypes. Concerning all genotypes, the shear force values increased from fast- to slow-growing chickens. In conclusion, this study found a difference between the genotypes. Although the slow-growing chickens showed the lowest dressing out and breast percentages compared with the other genotypes, the breast meat of the slow-growing chickens had more favourable nutritional properties.

Among the varieties of pineapples, honey pineapple is suitable to be processed as a probiotic beverage. The study aimed to evaluate the honey pineapple juice as a growth medium for Lactiplantibacillus plantarum subsp. plantarum Dad-13 probiotic strain. The pineapple juice was fermented by adding a starter culture of L. plantarum Dad-13. The fermentation time (0, 4, 8, 12, 16, 20, and 24 h) was used as a variable. The number of L. plantarum Dad-13 cells increased significantly after fermentation (P < 0.05). In acidic pineapple juice L. plantarum Dad-13 can still grow more than 2 log cycles. After 16 h, the results showed the best characteristics with cell count (8.86 log CFU·mL–1), pH (3.52), and titratable acidity (0.59%). To balance the sour taste, the 8% sucrose addition was the most preferred by the panellists (n = 67), with a 5.74 (slightly like) overall acceptance score. After 42 days, there was no significant decrease in cell viability. The number of cells on day 42 was 8.81 log CFU·mL–1 with significant changes in pH and titratable acidity. The study showed that honey pineapple juice is a suitable growth medium for Lplantarum Dad-13.

The aim of this work was to study the use of different types of wood products by the G20 countries. In the current scenario, every country is concerned about the severe exploitation of forests and the ensuing lack of markets for timber. Production and consumption of wood and wood products by the G20 countries account for 85% of global GDP and two-thirds of the world's population. Data for the study includes eight major categories of wood products in the G20 countries from 2004 to 2021: industrial raw wood, sawlogs and veneer logs, sawn wood, wood fuel, wood-based panels, paper and paperboard, pulp for paper, wood pellets, and other agglomerates. Autoregressive integrated moving average (ARIMA) models were used to predict the production, export, and import behaviour of wood and wood products from 2022 to 2030. According to the findings, the G20 countries would consume 1 644.6 million m3 of industrial raw wood in 2030, followed by 984.8 million m3 of sawlogs and veneer logs, 454.7 million m3 of sawn wood, 882.5 million m3 of wood fuel, 406.2 million t of paper and paperboard, 199.4 million t of pulp for paper, and 51.7 million t of wood pellets and other agglomerates. This study provides decision-makers with an analysis of the production and consumption of wood product markets in the G20 countries, which can be used for policy decisions.

Suaeda schimperi, a halophyte native to the Red Sea’s hyper-arid salt marshes, thrives in its extreme conditions (high salinity, minimal rainfall, and elevated temperatures). However, its adaptive tolerance mechanisms to these harsh conditions remain unclear. Herein, we investigated its growth responses and physiological mechanisms after short (5 days after treatment; DAT) and long-term (15 DAT) exposure to 0, 100, 200, and 400 mmol NaCl. Moderate salinity (200 mmol NaCl) enhanced growth, inducing 103.2% (5 DAT) and 40% (15 DAT) higher leaf biomass and 43.33% and 59.6% higher root biomass, respectively, compared to non-saline conditions. Deviation from moderate salinity reduced growth and disrupted ion balance, lowering K+, raising Na+, and increasing the Na+/K+ ratio, particularly under high salinity. The moderate salinity-enhanced growth was associated with increased chlorophyll, glycine betaine, glutathione, betacyanin, and betaxanthin, as well as higher antioxidant enzyme activity (polyphenol oxidase, peroxidase, catalase, ascorbate, and peroxidase) at 5 DAT. At 15 DAT, sugar accumulation and unsaturated fatty acids increased, while malondialdehyde and saturated fatty acids decreased. These findings reveal multiple adaptive strategies that support S. schimperi’s physiological stability under extreme environments and highlight its significance in ecological restoration and breeding salt-tolerant crops under escalating soil salinisation and climate change.

J. For. Sci., 2025, 71(7):347-357 | DOI: 10.17221/37/2025-JFS

Forest bathing is gaining attention for its health and well-being benefits, leading to growing interest among academics, policymakers, and practitioners. While most studies have focused on its physiological and psychological effects, less is known about how different stakeholders perceive the characteristics that make forest bathing effective and meaningful. This study explored expert and non-expert perspectives on forest bathing in Italy through the Q-methodology, aiming to identify shared and divergent views on key aspects such as site features, accessibility, and perceived benefits. The results highlighted four distinct viewpoints: a scientific-health-oriented perspective emphasising medical efficacy (mainly experts); a preference for more naturalness and ecological integrity (mainly non-experts); a possible socio-economic opportunity (mainly non-experts); and a preference for a more managed forest environment with supporting structures (mainly experts). Despite differences, consensus emerged on several points, including the cultural and physical relevance of forest bathing and the importance of inclusive accessibility while preserving low-impact environments. The findings highlighted the potential of Q-methodology to capture the plurality of stakeholder voices, offering a basis for more inclusive planning and policy development in the context of nature-based well-being initiatives.

Czech J. Anim. Sci., 2025, 70(8):345-356 | DOI: 10.17221/82/2025-CJAS


This study aimed to evaluate the effects of hop extract in the form of xanthohumol (XA) and humic substances (HS) supplementation in the rabbit diet on growth performance, carcass traits, blood biochemical parameters, and the qualitative and sensory properties of rabbit meat. Experimental material consisted of 60 Big Light Silver × Chinchilla Giant crossbred rabbits, randomly assigned to three dietary groups. Experimental groups, XA and HS, were fed pellets enriched with 1.0% XA or 1.0% HS, respectively, for 63 days during the fattening period. Control group (C), consisting of rabbits that received a basal diet without supplements. In the XA group, the higher final live weight and carcass weight were recorded at the end of the fattening period, along with increased protein content and collagen-free muscle protein (BEFFE) in the leg and loin muscles, compared to the control group. In contrast, the HS-supplemented group exhibited the lower final live weight and carcass weight, along with reduced fat content in the leg and loin muscles, as reflected in lower blood cholesterol levels. Additionally, elevated blood serum calcium and phosphorus levels were observed in the HS group. Higher values of colourimetric parameters L* and h* (lightness and hue angle) were recorded in the leg meat of the XA group compared to the control group. Moreover, the results demonstrated that supplementation with 1.0% XA was more effective in delaying lipid oxidation in meat compared to the control group on the 7th day of refrigerated storage. In conclusion, the primary benefit of supplementing rabbit diets with 1% xanthohumol is improved growth performance, positively influenced by increased protein content, reduced fat content, and enhanced oxidative stability of the meat.

Several phosphorus (P) extraction tests are being used as soil P tests, but many studies have shown that the correlation of extractable P with plant yield and P uptake varies and sometimes is poor. Infinite sink extraction methods may be superior in estimating plant P availability. Soil P tests were evaluated for their power in determining plant-available P pools. Thirty arable soils covering different soil groups were tested for soil characteristics and extractable P pools. Rye was grown on these soils for six weeks and analysed for shoot yield and shoot P concentrations. Correlations between soil P concentrations, shoot yield and shoot P content were investigated. Extractable P pools mostly significantly correlated with soil pH, texture and amorphous iron oxide content. High and significant correlations were found among most of the extractable soil P pools, except for calcium acetate lactate (CAL)-extractable P. In contrast to previous studies, diffusive gradients in thin films (DGT)-extractable P employed in our pot experiment did not perform better than other extraction methods in correlating with plant available P and uptake, likely because water availability was not a limiting factor of P diffusion. Plant-available P in the soils investigated in this study was controlled by P quantity (i.e. the amount of adsorbed P) and P intensity (i.e. the soil solution P). We conclude that the advantage of infinite sink extraction methods over equilibrium-based techniques becomes less apparent if P is not strongly intensity-controlled and water availability is not a limiting factor of P diffusion.

Vet Med - Czech, 2025, 70(12):432-441 | DOI: 10.17221/31/2025-VETMED

This experimental study evaluated the therapeutic potential of a liquorice-derived hydroalcoholic extract in managing experimentally induced peritonitis in New Zealand rabbits. The animals were randomly divided into six groups (n = 6): one control group, one negative control group (infected but untreated), three treatment groups that received the liquorice-derived extract at 0.5, 1, and 2 g/kg, and one positive control group treated with enrofloxacin. The confirmation of peritoneal infection relied on histopathological and radiographic tests. The effect of the liquorice extract on the peritoneal infection was evaluated using biochemical, haematological, and ultrasound analyses across the groups. The ultrasound examination, along with the haematological and biochemical evaluation on the 20th day after induction, showed significant differences between the groups. The results demonstrated that higher doses of 1 g/kg and 2 g/kg were more effective than the lower dose of 0.5 g/kg. The haematological and biochemical analyses revealed significant differences in several variables (including WBC, neutrophils, fibrinogen, and liver enzymes) between the treated and control groups, with the most pronounced improvements observed in the group receiving 2 g/kg of liquorice extract, suggesting a dose-dependent therapeutic effect. The administration of a hydroalcoholic extract of liquorice at different doses, along with the standard treatment with enrofloxacin, affected various haematological and biochemical variables in the context of peritoneal infection management. In conclusion, the effectiveness of the liquorice-derived extract is dose-dependent and could be used as an effective therapeutic agent in peritoneal infections in New Zealand rabbits. These findings showed that the liquorice-derived extract effectively improves the local inflammatory and structural changes associated with peritoneal infection without adversely affecting systemic biochemical homeostasis.

Soil salinisation is a key determinant in soil fertility decline, exerting a direct negative impact on soil organic carbon. In the context of global warming, investigating the response mechanisms of soil organic carbon pools with varying salinity levels to climate change is essential for accurately assessing the carbon cycle and emission potential of degraded soils. Based on soil samples (B1–B6) collected along a coastal salinity gradient, indoor incubation experiments were conducted at 15 °C and 25 °C to characterise soil respiration and its temperature sensitivity (Q10). Double-exponential models were used to simulate soil organic carbon (SOC) mineralisation, characterising active and stable organic carbon pools. The results demonstrated that the Q10 value of the stable organic carbon pool (7–8% of SOC mineralisation) was 103% higher than that of the active organic carbon pool (the initial 1% of SOC mineralisation). The Q10 value of the stable organic carbon pool was 32.6% higher at the high-salinity sites (B1, B2) than at the low-salinity sites (B4, B5). Soil organic carbon, total nitrogen (TN), and total salt (TS) were key regulators of Q10. The Q10 of the active organic carbon pool correlated positively with SOC and TN but negatively with TS, whereas the stable pool showed the opposite trends. The stable organic carbon pool exhibits a salinity-amplified Q10, implying that predictive models must account for this mechanism to avoid substantially underestimating carbon losses from degraded saline soils.

In order to remove soil tetracycline residue and identify the effect of tetracycline on soil nematode community, agricultural waste returning was applied in a maize monocropping field, northeast China. The results showed that plant parasites were the dominant genera in high concentration of soil tetracycline; however, bacterivores were the dominant genera in all organic matter amendments. Maturity index, structure index and enrichment index showed the highest values in biochar and compost mixed amendments and these treatments had the highest tetracycline removal rate and the highest concentration of macro-aggregates, total organic C and available N, followed by biochar seperate amendments. Overall, biochar and compost mixed amendments efficiently reduced the risk of soil tetracycline pollution below the threshold, with the characteristics of cheap, improving soil fertility and above all, environmentally friendly.

Curcuma longa L., known as turmeric, is a plant species belonging to the Zingiberaceae family. Turmeric is generally spread in Asian countries. It is used in many sectors, especially spices. It has been predicted that increasing climatic changes will affect the agricultural crop pattern. To provide an alternative crop for countries with sub-tropical climates, such as Turkey, the yield and quality values of turmeric grown under the greenhouse and shade net conditions were determined in the present study. Moreover, morphological traits such as plant height, tillering number, and leaf area were determined. The highest fresh yield (1 333.67 g/plant) was obtained under greenhouse conditions. Furthermore, the highest antioxidant value (3.01 IC50 mg/mg 2,2-diphenyl-1-picrylhydrazyl (DPPH)) was obtained under shade net conditions, while the highest total phenolic content (6.88 mg gallic acid equivalent (GAE)/g) was obtained under greenhouse conditions. Curcumin reached the highest level (1.79%) in greenhouse conditions. While the essential oil ratio varied between 5.22 and 7.32%, ar-turmerone, α-turmerone, and β-turmerone were determined as the main components in the essential oil. According to the results, turmeric can be grown in greenhouse conditions in subtropical regions.

The growing demand for vegetables free from pesticide residues has fuelled the search for sustainable pest management solutions. This study assessed the efficacy of azadirachtin, a neem-derived biopesticide, in achieving no detectable pesticide residues in tomato production under open-field conditions. The experiment, conducted from April to September 2024, included a systematic application and residue analysis using liquid chromatography-mass spectrometry (LC-MS). The results showed that azadirachtin degraded rapidly, with residual levels in leaves, green fruits, and mature fruits falling below the detection threshold (0.01 mg/kg) after 8–10 days following treatment. The statistical analysis revealed strong time-dependent residue dissipation, with little systemic buildup in fruit tissues. The findings suggest that azadirachtin is a viable, environmentally friendly alternative to synthetic pesticides, aligning with food safety requirements and customer preferences for pesticide residue-free fruit. Future research should investigate the ecological factors that affect degradation rates to optimise its application in diverse agro-climatic conditions.

The economic diversification of rural territories specialised in olive growing is key to the sustainability and resilience of these communities. In this context, olive oil tourism is presented as an innovative strategy to add value to the olive sector, attract visitors and promote public–private synergies. This study aims to determine the competitive advantages of olive oil tourism in the province of Jaén, Spain, using strategic analysis tools that align tourism resources with effective management strategies. Hence, in addition to a questionnaire completed by experts and a specialised literature review, we used the Quality Function Deployment (QFD) matrix, adapted to territorial analysis focused on tourism. This methodology correlates the territorial resources of olive oil tourism (TRs, the ‚what') with management specifications (MSs, the ‚how'). The analysis determines the relative importance of the TRs, the objective values and the technical importance of the MSs, and the direction of improvement. Furthermore, it includes an evaluation of competitiveness and estimates the technical-competitive positioning index. Nine TRs and eight MSs were identified and correlated, and Jaén's performance was compared to that of six other Spanish olive-growing provinces. Nine competitive advantages were identified, linked to five TRs (olive grove heritage landscape, tasting areas, exhibition centres, olive oil mills and greenways) and four MSs (olive mills, environmental education, diversification of supply and heritage promotion and innovation). This work proposes a useful tool to align resources and management, improve decision-making and move towards a more strategic governance in the olive oil tourism sector.

Oat (Avena sativa Linnaeus) has distinctive multifunctional characteristics and nutritional profile, as well as a large amount of oat-processing by-product comprises hulls, which contain lipids and other nutrients. In this study, the lipid content and fatty acid (FA) profiles of six naked oat varieties (Kamil, Marco Polo, Oliver, Patrik, Santini, and Saul), two hulled oat varieties (Atego and Korok), and their dehulled grains and hulls were analysed. The findings of the study demonstrated that the lipid content varied from 4.14 g·100 g–1 dry matter (DM) (Santini) to 6.68 g·100 g–1 DM (Kamil) in naked oats; 3.61 g·100 g–1 DM in Atego and 3.47 g·100 g–1 DM in Korok with hull; 0.70 g·100 g–1 DM in Atego hull and 0.71 g·100 g–1 DM in Korok hull. Dehulled oats had a higher lipid content than hulled oats. Linoleic and oleic acids were the predominant FAs in analysed samples. Oat hulls contained maximum amounts of saturated FAs (SFAs) (26% in Korok and 25.6% in Atego). Elimination of hulls raised the amount of linoleic acid and decreased the amount of oleic acid. Oat hull contained the least amount of linoleic acid and the highest amount of C20 : 0 (eicosanoic acid) and C22 : 0 (docosanoic acid). Oats are a significant source of lipids, predominantly comprising unsaturated fatty acids (UFAs). Moreover, oat hulls contribute to the lipid content although their FA composition, with higher palmitic acid and lower linoleic acid levels, differs from that of naked, hulled, and dehulled oats.

The beneficial reuse of sewage sludge in agricultural soils is limited by the accumulation of micropollutants of emerging concern, which may pose significant environmental and human health risks. This review summarises recent advances in understanding the occurrence, persistence, and fate of herbicides and their transformation products in sewage sludge. Data from various geographic regions are discussed, with a focus on implications for the safe reuse of biosolids in agriculture. Most available studies have been conducted in European Union countries, where land application of biosolids is a common practice. Twelve groups of herbicides and their transformation products have been identified in sewage sludge, including glyphosate and aminomethylphosphonic acid (AMPA), phenylureas, phenoxy acids, chloroacetamides, triazines and their metabolites, triazinones, phenylcarbamates, isoxazolidinones, benzoic acids, dinitroanilines, benzofurans, phenyl ethers, and other herbicides. Among these, triazines and their metabolites were the most frequently detected, with concentration ranges of 0.01–277 ng/g and not detected (n.d.)–237 ng/g, respectively. Glyphosate and AMPA were found at particularly high concentrations (n.d.–35 000 ng/g). Phenylurea herbicides (e.g., diuron and isoproturon) were detected in a limited number of studies, with concentrations ranging from not detected to 102 ng/g. Substantial concentrations of phenoxy herbicides (2,4-d, 2,4-db, and 2,4,5-t) were also reported in sewage sludge, ranging from 50.5–864 ng/g. The available scientific literature on the occurrence of herbicides in sewage sludge focuses mainly on older, often already banned compounds, while data on currently approved herbicides remain scarce. This review highlights the need for more comprehensive global assessments of herbicides and their transformation products in sewage sludge to ensure the safe agricultural use of biosolids and minimise risks to plants and other organisms. The current lack of systematic monitoring and documentation represents a critical knowledge gap in evaluating environmental exposure and associated risks.

High soil salinity causes a negative impact on plant growth and lowers crop yields. Thus, pot experiments were conducted to investigate the impact of foliar application of salicylic acid (SA) and proline (Pro), separately and combined, on enhancing salinity tolerance in broad beans. Salinity stress (4.69 ds/m and 6.25 ds/m) significantly reduced plant growth (plant height, leaf area, number of leaf/plant, plant dry weight), chlorophyll pigment content (chlorophyll a, b or total), relative water content, K/Na ratio, seed yield per plant, and N, P, K, and crude protein content in broad bean seeds. Foliar application of Pro and SA, either individually or in combination, enhanced plant growth parameters, chlorophyll pigment content, endogenous proline levels, phenol content, and the activities of antioxidant enzymes [antioxidant enzymes including catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD)]. Additionally, these treatments enhanced plant seed yield, N, P, K, and crude protein levels in the seeds. The combined foliar application of Pro and SA was more effective in mitigating salinity stress’s harmful effects than using either substance alone. These findings indicate that foliar application of SA and Pro, either individually or in combination, alleviated the adverse effects of salinity on broad beans, with the combined application proving to be the most effective.

Crop production faces increased climate change and land degradation stresses, compromising global food security with the growing population. Maize (Zea mays L.) is a versatile crop used for food, feed, and raw materials, contributing significantly to global food systems. Abiotic stresses like drought and soil fertility limit its production. Fertilisation is an amelioration technique that optimises maize growth and yield by maintaining optimum nutrition and leveraging nutrient deficiency conditions. Precision agricultural tools like chlorophyll meters are essential for non-destructive chlorophyll assessment and nitrogen status. An experiment conducted at the University of Debrecen evaluated the impact of nitrogen (N) fertilisation (0, 90, and 150 kg/ha) and three maize cultivars (P9610-FAO 340, DKC4590-FAO360, and GKT376-FAO360) on physiological parameters, namely: relative chlorophyll content (SPAD), normalised differences vegetation index (NDVI) and grain quality. Results showed that SPAD and NDVI positively correlated (P < 0.05) with grain quality and yield. Nitrogen application significantly influenced SPAD. Maize cultivars and N rates with higher chlorophyll content had maximum yield. Cultivar responses to nitrogen rates significantly (P < 0.05) varied by crop year. Higher SPAD and NDVI values were associated with higher protein content. Therefore, SPAD and NDVI values could be used to analyse the nutrient requirements of maize under field conditions to estimate grain yield.

Nitrogen fertiliser is a key determinant of rice yield and grain quality; however, the synergistic mechanisms through which nitrogen regulates root anatomical structure, physiological traits, and cooking quality in rice varieties with different eating properties remain unclear. In this study, a pot experiment was conducted using two moderate-eating-quality cultivars (Xudao 3 and Huageng 9) and two superior-eating-quality cultivars (Zhengdao C42 and Nangeng 9308) under four nitrogen levels (0, 0.59, 1.18, and 1.76 g/pot, designated as N0, N1, N2, and N3, respectively). Cooking quality was assessed by amylose content, gel consistency, and alkali spreading value. The results demonstrated that, with increasing nitrogen application, amylose content, alkali spreading value, malondialdehyde (MDA) content, root aerenchyma area, and aerenchyma proportion decreased initially, then increased, reaching their lowest values at the N2 level. In contrast, gel consistency, root antioxidant enzyme activities (SOD, POD, CAT), photosynthetic rate and cortical living cell proportion increased first and then decreased, peaking at N2 treatment. Compared with moderate-eating-quality varieties, superior-eating-quality varieties exhibited significantly lower amylose content, alkali spreading value, MDA content, and aerenchyma proportion, but higher gel consistency, living cell proportion, stele-to-root diameter ratio, antioxidant enzyme activities, and photosynthetic rate. Correlation analysis revealed that root antioxidant enzyme activities, stele diameter and living cell proportion were negatively correlated with amylose content, but positively correlated with gel consistency. Conversely, MDA content, aerenchyma area and aerenchyma proportion showed opposite correlation patterns. These findings indicate that an appropriate nitrogen application rate (1.18 g/pot) enhances root physiological activity, optimises root anatomical structure, and ensures sufficient source supply to the grain sink, thereby synergistically improving cooking quality – an effect particularly pronounced in high-eating-quality rice varieties.

Selenium (Se) supplementation is a common practice in dairy nutrition. However, the use of biofortified feedstuffs remains a not fully realized strategy to enhance the Se content of animal derived products. This study explored an on-farm biofortification approach by incorporating Se-enriched maize silage into the total mixed ration (TMR) of dairy cows. Sixty Holstein cows were divided into a control group (CON), receiving a conventional diet with selenite supplementation (0.6 mg/kg Se in TMR), and an experimental group (EXP), in which conventional silage was replaced with high-Se silage (0.9 mg/kg Se in TMR). The trial lasted 22 weeks, including one week of adaptation and four weeks after supplementation, when Se concentrations in milk, Se transfer efficiency, and key milk components critical for the production of Se-enriched dairy products were assessed. The higher Se concentration in the TMR had no adverse effects on milk composition or antioxidant status. Milk Se concentration in the EXP group increased rapidly, reaching 68 µg/l within two weeks, significantly higher (P < 0.005) than in the CON group (27 µg/l). Se transfer efficiency to milk was also higher in the EXP group (13.9%) compared to the CON group (8.8%). The diverse Se species in biofortified silage, confirmed through the speciation analysis, may have contributed to these outcomes. However, the gradual decline in milk Se after the initial peak warrants further investigation into physiological factors or changes in silage Se speciation during storage.

This study aimed to evaluate the therapeutic efficacy of a ceftiofur-neomycin combination against a pathogenic multidrug-resistant Escherichia coli strain, KECS-0513, isolated from pigs, using a combination of genomic, in vitro, and in vivo approaches. The minimum inhibitory concentration, minimum bactericidal concentration, and checkerboard assays were performed. Time–kill assays were used to assess bactericidal activity over time, and a murine intraperitoneal infection model was used to evaluate survival outcomes following treatment with monotherapies or combination regimens. Whole genome sequencing indicated that KECS-0513 harboured multiple resistance genes, including blaTEM-1B, sul3, aadA12, aad(3)-IVa, aph(3’)-Ia, and aph(4)-Ia. The resistance genes were localised within a mobile, element-rich plasmid. In vitro checkerboard assays revealed an additive interaction between ceftiofur and neomycin (fractional inhibitory concentration index = 1.0), and time–kill experiments demonstrated enhanced and sustained bacterial clearance with combination therapy. In vivo infection studies in mice demonstrated that the dual treatment resulted in a substantially higher survival rate (66.7%) compared to treatment with either agent alone (33.3% for each). These results support the practical application of ceftiofur-neomycin combination therapy for controlling swine-associated multidrug-resistant E. coli while minimising the risk of resistance emergence.

Drone brood homogenate (DBH), a nutrient-rich bee product, has received limited scientific attention despite its potential immunomodulatory and gut-protective properties. This study evaluated the effects of a dietary DBH supplementation on the intestinal barrier–related gene expression, phagocytic activity, and lymphocyte subpopulations in pigs. Eighteen weaned pigs were assigned to three groups (control, DBH100, DBH200) and fed DBH at 0, 100, or 200 mg/kg feed for 18 days. The gene expression of tight junction markers (occludin, claudin-1) and mucosal integrity–associated proteins (lumican, OLFM4) was assessed in the ileum by qRT-PCR. Phagocyte function and peripheral blood lymphocyte subpopulations were analysed by flow cytometry. DBH200 significantly upregulated the occludin, claudin-1, lumican, and OLFM4 expression, indicating enhanced intestinal barrier support. The phagocytes from both DBH-treated groups exhibited an increased engulfing capacity and an elevated oxidative burst index, though the percentage of active phagocytes was only weakly affected. The DBH supplementation did not alter the total T (CD3+) or B (CD21+) cells; however, both DBH groups showed a significantly increased CD4+ : CD8+ lymphocyte ratio, which is consistent with immune stimulation. These findings suggest that DBH may beneficially modulate the gut barrier integrity and selected components of innate and adaptive cellular immunity in pigs.

This study investigated the effects of temperature on the performance of anaerobic digesters for biogas production. Digesters were filled with a 1 : 1 ratio of substrate to water, containing 15 kg of cow dung and 3 kg of crop waste, and maintained at temperatures of 50 ± 2 °C and 30 ± 2 °C, corresponding to the thermophilic and mesophilic biodigesters, respectively. The experiments run for 75 days, and biogas production rate and purity were measured. The thermophilic digester produced 48.4% more biogas and had a slightly higher pH (7.65) than did the mesophilic digester (7.37) by the end of the observation period. However, gas chromatography revealed that the CH4 and CO2 contents did not significantly differ between the two treatments. The CH4 concentration in the mesophilic environment was 42 ± 10%, whereas that in the thermophilic environment was 53.5 ± 10%. The CO2 composition was 32.5 ± 1% and 35.5 ± 1% for the mesophilic and thermophilic setups, respectively. These were supported by the wavelength (460 nm to 620 nm) of the flame colour, indicating that the biogas from both setups is predominantly composed of methane. In conclusion, thermophilic anaerobic digesters may have a relatively high biogas production rate, but the biogas purity is not significantly different from that of mesophilic digesters.
