Vet Med - Czech, 2023, 68(4):152-163 | DOI: 10.17221/109/2022-VETMED

This study was planned to investigate an alternative treatment modality in diabetic wound healing. In this experimental study, the efficacy of both cold atmospheric plasma/nitric oxide (NO) and NPH insulin ointment, recently known to have beneficial effects on wound healing, was investigated in diabetic wound healing. Twenty-four (24) diabetic rats were divided into four groups DC, DI, DNO and DINO (diabetic control, diabetic insulin, diabetic nitric oxide, diabetic insulin + nitric oxide groups). No treatment was applied to the DC group, NPH insulin was applied to the DI group, CAP/NO was applied to the DNO group, and CAP/NO + NPH insulin was applied to the DINO group once daily for 14 days. The wound area reduction and the wound contraction rate were calculated on the basis of the tissue sections taken, and histopathological and genetic analyses were carried out. Compared to the control group, exogenous NO gas was found to be a potent antibacterial agent in the diabetic wound healing, causing a reduction in the wound area (P = 0.034), an increased contraction rate (P = 0.021), epithelialisation (P = 0.02), collagen organisation (P = 0.006) and a reduction in the number of inflammatory cells (P = 0.002). A significant increase in the expression of IL-8 mRNA was observed (P = 0.026). It was concluded that NPH insulin alone contributes to wound healing, but it is not necessary to use it together with exogenous NO gas.

Developing natural herbicides offers a potential solution to mitigate the drawbacks associated with synthetic pesticides used in an excessive quantity to safeguard agricultural crops. In this study, essential oils extracted via hydrodistillation from Pinus ponderosa needles were investigated for their chemical composition and phytotoxic activity. Gas chromatography with mass spectrometry detection (GC/MS) identified twenty-three constituents, constituting 93.87% of the total oil. The predominant components were oxygenated monoterpenes (64.66%), with α-pinene (37.78%), β-pinene (24.32%), and sesquiterpenes hydrocarbons, particularly germacrene-D (7.26%). The phytotoxic effects of P. ponderosa essential oil were tested on Phalaris canariensis L., Trifolium campestre Schreb., and Sinapis arvensis L. The essential oil exhibited a significant inhibitory effect on seed germination and seedling growth in a dose-dependent manner. A low concentration of essential oil reduced the germination and seedling growth of all tested weeds. Additionally, the essential oil treatment impacted malondialdehyde content and electrolyte leakage in the seedlings. These preliminary findings suggest that essential oils from forest trees, particularly Pinus ponderosa, could serve as an eco-friendly alternative to chemical herbicides. This approach may contribute to addressing the challenges associated with synthetic pesticides while promoting sustainable and environmentally friendly agricultural practices.

Plant Protect. Sci., 2025, 61(2):183-190 | DOI: 10.17221/3/2024-PPS

The study has been conducted at Research Farm, College of Agriculture, Gwalior (M.P.), in the summers of 2021 and 2022. In the summers of 2021 and 2022, the crop was first infested by the shoot and fruit borer on the 10th and 13th standard meteorological week (SMW). The infestation persisted until the 23rd and 24th SMW, respectively. During the first year, the 15th SMW had the highest infestation rate for shoot damage, 15.76%, while the 18th SMW had the highest infestation rate for shoot damage, 15.07%, in the second year. Whereas fruit damage per cent is calculated based on number and weight, and its peak per cent infestation was noted on the 22nd SMW with 31.67% based on number, 30.12% based on weight during the first year, and 30.34% based on number and 29.95% based on weight during the second year, which was noted on the 23rd SMW. There was a significant positive correlation between maximum temperature and shoot damage percentage (r = 0.62) and minimum temperature and fruit damage percentage based on number (r = 0.87) and weight (r = 0.88) during the first year of study. However, during the first year of the study, there was a negative association (r = –0.68) between morning relative humidity and shoot damage per cent. The following year's research revealed a highly significant positive link between maximum temperature, minimum temperature, and evaporation with fruit damage (%) based on the number (r = 0.64, 0.92, and 0.82) and based on weight (r = 0.63, 0.92, and 0.82), respectively.

J. For. Sci., 2025, 71(12):589-598 | DOI: 10.17221/73/2025-JFS

This study investigates the long-term effects of pine (Pinus nigra) afforestation on soil characteristics in comparison to adjacent pastureland in central Kosovo. Soil samples (n = 24) were collected from two land-use types, pine plantations and grassland, over three topographic positions (lower, medium, upper) and two depths (0–10 cm and 10–20 cm). Standard laboratory techniques were used to determine soil organic matter (SOM), organic carbon (SOC), total nitrogen (TN), pH (H2O and CaCl2), available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and bulk density (BD). The data were analysed using principal component analysis (PCA) and correlation matrices. The top soils (0–10 cm) beneath pine had higher soil organic matter (mean 2.45%) compared to the pasture lane (1.59%). The SOC and TN levels increased by 43% and 36%, respectively. Soil pH was lower under pine (mean pH_H2O = 6.3) than under pasture land (pH_H2O = 6.81), particularly on middle and lower slopes. Exchangeable calcium and magnesium declined by up to 20% under pine plantations, and bulk density also decreased (for example, 1.15 g·cm–3 under pine land compared to 1.29 g·cm–3 under pasture land), signifying reduced compaction. Phosphorus concentrations were slightly higher under pasture at a depth of 0–10 cm (mean 12.4 mg·100 g–1), but under pine, they increased at a depth of 10–20 cm on top slopes. PCA showed differentiation based on land use, with the initial two components representing 70.1% of the overall variance.

Ifeanyi Michael Smarte Anekwe, Yusuf Makarfi Isa*

Soil & Water Res., 2024, 19(2):100-110 | DOI: 10.17221/66/2023-SWR

The purpose of this study was to evaluate the application of biostimulation and bioventing for the treatment of crude oil-contaminated soils. The research needed to check how various industrial biostimulants will perform in the treatment of contaminated soils and whether or not there is a synergetic effect that has to do with the stimulant composition. Soil samples used for this study were collected from South Africa. The soil samples were air-dried for 24 h and subsequently passed through a standard sieve of 2 mm screen. The soil consists of 79.32% sand (2.00–0.02 mm), 14.71% silt (0.02–0.002 mm) and 5.97% clay (< 0.002 mm). A microcosm system containing 1 kg of soil contaminated with crude oil (5% w/w) for biostimulation (BSTc) treatment was amended with varying ratios of municipal wastewater (MWW) and brewery wastewater (BWW) to investigate the possible synergy. The bioventing (BVTc) treatment involves the supply of atmospheric air to the bioreactors through the vadose zone for 30mins flow duration every 48 h intervals at ambient condition for 28 days. The BSTc and BVTc treatments recorded 48–58% and 54–75% total petroleum hydrocarbon (TPH) removal efficiencies, respectively, as the BWW amendment noted appreciable removal compared to MWW, while the control treatment recorded 35%. The result showed that the attempt to boost the TPH removal efficiency using the bioventing with the wastewater amendment was effective, as the presence of enough oxygen in the system resuscitated the activities of the microbial community for enhanced TPH biodegradation. This study inferred that combined bioventing and biostimulation techniques proved to be an effective bioremediation strategy for the treatment of crude oil contaminated soils and could serve as a vital tool towards the mitigation of pollution aftermath faced by communities involved in oil production and/or processing activities.

Vet Med - Czech, 2025, 70(1):30-34 | DOI: 10.17221/51/2024-VETMED


One of the disorders of the mammary gland in the queen is feline mammary fibroadenomatous hyperplasia (FMFH), caused by an increasing concentration of progesterone (P4) and some other local growth factors. It occurs mostly during puberty after the heat characterised by spontaneous or provoked ovulation, as a result of exogenous progesterone intake and sometimes during pregnancy. To diagnose a 14-month-old intact Maine Coon queen with extensive mammary gland hyperplasia, a clinical examination, analyses of the progesterone (P4) concentrations and ultrasound examination were performed. Feline mammary fibroadenomatous hyperplasia associated with a high P4 concentration after spontaneous ovulation was confirmed. After 24 days of therapy with a progesterone antagonist, aglepristone, the symptoms of FMFH resolved. After the next eight weeks, the queen was mated after the owner’s decision. In the third week of pregnancy, a relapse was detected (mammary gland enlargement, pain, discomfort). At the same time, no abnormalities in the uterus or embryos were detected via ultrasound. The P4 concentrations were under regular control. For the next two weeks, only conservative treatment with NSAIDs was used. The queen spontaneously delivered six kittens without any difficulties or perinatal complications 67 days after the first mating. The cat previously treated with aglepristone for FMFH was successfully bred, but FMFH symptoms returned when progesterone concentrations increased during pregnancy.

Effects of age and litter-of-origin on cryopreserved spermatozoa in Sumava ramsOriginal Paper

Ane¾ka Málková, Martin Ptáèek, Filipp Georgijeviè Savvulidi, Szabolcs Tamás Nagy, Ludìk Stádník

Czech J. Anim. Sci., 2024, 69(4):129-138 | DOI: 10.17221/32/2024-CJAS

This study aimed to evaluate the influence of the internal factors of ram age and litter-of-origin on semen quality during the cryopreservation process in Sumava sheep rams. This breed is included in the protected genetic resources of the Czech Republic. The sires were systematically divided into four groups according to age (under 1.5 years, 1.5 to 2.5 years, 2.5 to 3.5 years, and over 4.5 years) and according to litter frequency (singletons vs twins). Semen was evaluated after equilibration, and after cryopreservation using iSperm® mCASA and flow cytometry. During cryopreservation, there was a significant decrease in total sperm motility by 53.5%, progressive motility by 38%, and cells with intact plasma membrane and acrosome by 47%. Frozen-thawed sperm kinematic parameters showed significant age-related variations, with rams aged 4.5 and older displaying notably higher total and progressive motility (16.2% and 6.24%, respectively). Rams born as twins exhibited 3.77% (P < 0.05) higher progressive motility and 5.5% (P < 0.05) higher total motility compared to those born as singles. The sperm of older rams (> 4.5 years) exhibited higher viability (10.1%) and lower damage to the plasma membrane after freeze-thawing (23.6%), (P < 0.05). Twins showed significantly higher sperm viability (4.98%, P < 0.05) than singletons. These rams produce a larger quantity of higher-quality insemination doses after cryopreservation. For Sumava rams, in particular, broadening the sire selection base helps to select suitable rams for breeding. As the sire ages, his genetic value within the production herd may decline with time. This contrasts with genetic resource protection, where the aim is to preserve and store as many high-quality semen samples as possible.

Most farmers use urea as a nitrogen fertiliser to raise mustard (Brassica juncea L.), although its nitrogen (N) content is quickly lost due to its hygroscopic nature. Nitrogen loss in the form of nitrous oxide (N2O) and nitrates (NO3) has been causing low nitrogen fertiliser efficiency in vegetable cultivation. This investigation aims to assess the impact of urea fertiliser coated with biochar or activated charcoal on losses of N2O and NO3 concentration in the soil during mustard production. The experiment used a randomised block design with five treatments of urea fertiliser coated with biochar/activated charcoal. The observed data included N2O flux, nitrate, and ammonia content in soil and water. The results showed that urea fertiliser coated with activated charcoal from corn cobs tended to suppress N loss more effectively than urea coated with biochar or activated charcoal from coconut shells. Biochar and activated charcoal from coconut shells suppressed N-N2O loss as much as 3.1% and 52.5% (7 days after planting (DAP)), respectively, and 68.7% and 71.6% (21 DAP), respectively. Biochar and activated charcoal from corn cob reduce N-N2O loss by 46.5% and 66.5% (7 DAP), respectively, and by 70.7% and 77.8% (21 DAP). Urea-coated activated charcoal fertiliser increases mustard plant biomass and nitrogen uptake. Biochar and activated charcoal from coconut shells and corncobs increase nitrogen use efficiency by 5, 24, 6, and 17%, respectively. Biochar/activated charcoal coatings are a promising technology for boosting nitrogen use efficiency in vegetable crops, including mustard crops.

Rhizosphere and non-rhizosphere soil organic carbon and its labile fractions in alpine desertified grassland affected by vegetation restorationOriginal Paper

Chuanyu Zhou, Hongyu Qian, Aiyang Liu, Yufu Hu, Wei Wang, Gang Chen, Zhi Li

Plant Soil Environ., 2024, 70(8):523-533 | DOI: 10.17221/106/2024-PSE

Grasslands are the predominant land use type in China, which is currently encountering significant desertification issues. Consequently, restoring grassland vegetation has important implications for terrestrial carbon (C) levels and, consequently, the global C balance. This study focused on Salix cupularis, the primary plant used for desert control on the eastern edge of the Qinghai-Tibet Plateau. We analysed the rhizosphere and non-rhizosphere soil up to the depth of 60 cm after Salix cupularis growth for 0–24 years, examining soil total organic carbon (TOC) and its labile fractions. Following restoration, there was a gradual increase in TOC and its labile fractions, with the most significant changes observed in the rhizosphere soil at a depth of 0–20 cm. After 24 years of restoration, the TOC content in both rhizosphere and non-rhizosphere soil had increased by 141.74% and 39.44%, respectively. Labile organic C in the rhizosphere soil increased more rapidly and pronouncedly compared with the TOC. Specifically, dissolved organic C and easily oxidised organic C in the rhizosphere soil saw substantial increases of 211.03% and 217.65%, respectively. Meanwhile, compared with the 4 years of restoration, soil C pool management index of the 8–24 years soils increased, ranging from 15.70% to 132.21%. Therefore, long-term vegetation restoration on the eastern margin of the Qinghai-Tibet Plateau can significantly enhance TOC and its labile fractions, as well as improve soil C sink capacity and quality.

Bovine respiratory disease (BRD) develops from complex interactions among environmental, host and pathogenic factors. This study aimed to phenotypically identify Enterobacter hormaechei isolated from cattle with BRD and assess antimicrobial susceptibility and determining the molecular phylogeny of local E. hormaechei strains. Between November 2023 and March 2024, nasal swabs were collected from 93 cattle with BRD, before culturing for phenotypic analysis, and performing the polymerase chain reaction (PCR) for molecular characterisation. Of the 93 samples evaluated, 15.79% and 24.56% tested positive for E. hormaechei isolates on culture and PCR, respectively. The local isolates exhibited high resistance to amoxicillin, ampicillin, amikacin, nalidixic acid and ceftazidime; high susceptibility to azithromycin, levofloxacin, gentamicin, ofloxacin, cefepime, ceftriaxone, cefotaxime, nitrofurantoin, ceftazidime and ciprofloxacin; and moderate susceptibility to ciprofloxacin, colistin, imipenem and meropenem. Multiple sequence alignment, phylogenetic tree analysis and homology sequence identification, showed that the five positive isolates were similar to the reference isolate. To the best of our knowledge, this is the first time that E. hormaechei has been isolated in cattle with BRD in Iraq. Because phenotype-based assays show limited accuracy to identify species, we recommend molecular and phylogenetic analysis be included in all similar studies in the future.

Y Ha, K Yi, C Park, G Kim, D Choi, J Lee, N Kim

Vet Med - Czech, 2024, 69(11):381-388 | DOI: 10.17221/24/2024-VETMED


This study aimed to measure the whole blood viscosity (WBV) in racehorses using a new viscometer and establish reference values, as well as to investigate the correlation between the WBV and the haematological parameters and serum chemistry. WBV measurements were conducted on 51 Thoroughbred horses using a novel U-shaped scanning capillary-tube viscometer. The reference values for the WBV were determined at various shear rates ranging from 1 s–1 to 1 000 s–1. Correlation analyses were performed to examine the correlation between the WBV and the haematological and serum chemistry parameters. The findings provide valuable reference data for the WBV in Thoroughbred horses and enhance understanding of the relationship between the WBV and routine blood tests in equine health assessment.

Kristýna Klímová, Kristýna Lokvencová, Ivan Bahelka, Kateøina Zadinová, Roman Stupka, Jaroslav Èítek

Czech J. Anim. Sci., 2025, 70(9):397-403 | DOI: 10.17221/72/2025-CJAS


In the Czech Republic, the pig carcass classification is mandatory in slaughterhouses processing over 200 pigs weekly. As breeding practices evolve to enhance lean meat yield, it is essential to update regression equations used in classification systems. This study presents new regression models for the Fat-O-Meater II (FOM II) device, using computed tomography (CT) as the reference method. Separate equations were developed for barrows, gilts, and boars to improve the accuracy of lean meat percentage (LMC) estimation. To calibrate the CT method, 24 carcasses were selected across a range of backfat thicknesses and sexes. CT scans were performed on chilled left carcass halves, followed by manual dissection to determine the true LMC. A correction model was applied to align the CT-derived LMC with dissection results. Subsequently, 128 carcasses were measured using FOM II and CT to develop sex-specific regression equations using ordinary least squares. The models revealed sex-specific differences in prediction accuracy. Gilts achieved an R2 of 0.66 and RMSEP of 1.35; barrows had higher R2 (0.759) and greater RMSEP (1.46); boars showed the most consistent composition (R2 = 0.734, RMSEP = 1.14). Compared to the standard method, gilts and boars had slightly higher LMC (+0.03% and +0.82%), while barrows had lower LMC (–0.14%). These differences translated into economic impacts, with gains of CZK 1.23 and CZK 4.33 per gilt and boar carcass, respectively, and a loss of CZK 5.55 per barrow carcass. These results support the formulated hypotheses, and the fact that sex-specific calibration enhances classification accuracy and economic efficiency.

Balancing conservation and intervention: Managing forest diebacks in Slovakia's Tatra National ParkOriginal Paper

Paula Pu¹kárová, Mikulá¹ Èernota, Ján Slivinský

J. For. Sci., 2026, 72(3):119-135 | DOI: 10.17221/87/2025-JFS


Disturbance regimes in Central European mountain forests are changing under the ongoing climate change, raising questions about how protected areas should respond to increasingly frequent windthrow and bark beetle outbreaks. In Tatra National Park, a major windstorm in 2004 triggered a landscape-scale bark beetle eruption that challenged long-standing expectations that non-intervention alone could safeguard forest ecosystems. Using the Socio-Ecological Systems framework, we combined long-term field observations with archival sources and stakeholder interviews to examine how ecological dynamics, governance structures, and actor perspectives interacted during and after the outbreak. We show that warming, abundant post-storm breeding substrate, and legacy Norwegian spruce (Picea abies) monocultures reduced forest resilience and enabled successive beetle waves. Governance fragmentation led to delayed decision-making, allowing large volumes of wind-felled timber to remain untreated and facilitating its spread into high-naturalness stands. In contrast, evidence from other European countries suggests that timely, spatially focused measures can reduce outbreak duration without compromising conservation values. Our results indicate that in disturbance-prone, spruce-dominated forest systems experiencing climate change, a combination of strict protection in core areas and timely, selective measures in adjacent zones is more likely to maintain resilience and support conservation outcomes than strictly passive or fully interventionist approaches.

Nexus of agricultural informatisation and sustainable practices: Food security implications for drought-affected maize farmers in ZambiaOriginal Paper

Shangao Wang, Gershom Endelani Mwalupaso, Xianhui Geng, Emmanuel Kiprop, Jotham Bett, Dancun Kibiwott Kimwei

Agric. Econ. - Czech, 2026, 72(2):101-119 | DOI: 10.17221/84/2025-AGRICECON

Agricultural informatisation (AgI) is hailed as a 'game-changer' for farmers worldwide, even as climate change increases agriculture's vulnerability to climatic risks and threatens sustainable agrifood production. While AgI aspires to help alleviate hunger and poverty in smallholder farm households by improving on-farm productivity through the promotion of sustainable agricultural practices (SAPs), limited empirical evidence exists on the AgI–SAPs nexus, particularly under severe environmental stress such as drought. We analysed data from a survey of maize farmers in central Zambia – a country exemplifying the impact of severe drought, declared a national emergency and disaster – to explore whether and how AgI can optimise SAP adoption and improve crop yields. Given the potential endogeneity of AgI adoption, we employed a recursive bivariate probit (RBP) and endogenous-treatment regression (ETR) to estimate the former and the latter, respectively. We focused on adoption portfolios of three AgI tools – radio, television and mobile phones – and five SAPs: minimum tillage, residue retention, planting basins, improved seed varieties and irrigation. The results reveal that AgI adoption significantly influences SAP adoption, with varying impacts across different AgI and SAP portfolios. Importantly, the adoption of productivity-enhancing SAPs, particularly improved seed and drip irrigation, produced the largest yield effects (124.46 g/capita/day) for AgI adopters. This increase potentially contributes 43.21% towards daily maize-supply quantity, which is crucial for helping households meet the minimum recommended daily caloric intake. The study therefore underscores that AgI plays a critical role in improving yields through SAP adoption, serving as a compelling pathway for agricultural resilience, especially under adverse climatic conditions. These insights align with the United Nations Sustainable Development Goals (SDGs), particularly those aimed at zero hunger, climate action and poverty alleviation, which advocate re-thinking and transforming food-production strategies.

Influence of dietary coriander seeds and administration of Lactobacillus acidophilus on the performance of growing rabbits under subtropical climatic conditionsOriginal Paper

SM Abdel-Raheem, MA Kobeisy, YA Gomaa, AMA Meligy, M Elalfy, MM Farghaly

Vet Med - Czech, 2025, 70(9):313-328 | DOI: 10.17221/104/2024-VETMED

This study investigated the effects of coriander seed powder and Lactobacillus acidophilus solution (LAS) on the growth, nutrient digestibility, blood parameters, and intestinal health of growing rabbits under subtropical conditions. Forty Californian rabbits, aged 35 days with an average body weight of 588 ± 34 g, were randomly assigned to four groups: a control group fed a standard diet, a group (T1) receiving the basal diet supplemented with 1.5% coriander seed powder, a group (T2) receiving the basal diet with oral LAS at 1 × 109 CFU/kg, and a group (T3) receiving both coriander seed powder and LAS. The study measured body weight, daily weight gain, feed conversion ratio, mortality rate, blood metabolites, nutrient digestibility, and intestinal histomorphology. Results showed that rabbits fed with 1.5% coriander seed powder had significant improvements in body weight gain, feed conversion, and a reduction in mortality compared to the control. Both coriander seed powder and LAS improved blood metabolites, nutrient digestibility, and intestinal health. However, the combination of both additives did not provide additional benefits over the individual treatments. The findings suggest that either 1.5% coriander seed powder or LAS can enhance growth performance and health in rabbits under subtropical conditions.

Mechanisms of overwintering frost tolerance in alfalfa roots based on 4D-Label-free quantitative proteomicsOriginal Paper

Yajun Ma, Yu Zhang, Qiaoxian Zhang, Guo Sun, Yajun Yan, Chuan Wang, Wenbin Mian, Tianhui Yang, Ting Gao

Czech J. Genet. Plant Breed., 2025, 61(4):181-192 | DOI: 10.17221/27/2025-CJGPB


The present study investigates the differential protein expression levels between the frost-tolerant variety Qingda No.1 and the frost-sensitive variety Gannong No.9. The analysis was conducted using 4D-Label-free quantitative proteomics technology, with the samples collected prior to and after overwintering. The results showed that the protein expression of Qingda No.1 changed more significantly during the overwintering process, with 451 differentially expressed proteins (DEPs) being identified, of which 224 were up-regulated and 227 down-regulated. In contrast, the protein expression of Gannong No.9 differed from that of alfalfa roots of the frost-sensitive variety, with 204 DEPs being identified, of which 93 were up-regulated and 111 down-regulated. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that the phenylpropanoid biosynthesis pathway was significantly enriched in both groups. Furthermore, enzymes such as phenylalanine ammonia-lyase (PAL), cinnamic acid 4-hydroxylase (C4H), and chalcone isomerase (CHI) were significantly up-regulated in the freezing-tolerant varieties. Protein interaction network analysis revealed the synergistic regulation mode of DEPs. The present study elucidated the metabolic adaptive mechanism of overwintering in alfalfa roots at the protein level, thus providing a theoretical basis for the selection and breeding of frost-tolerant varieties.

Alternative solution for determining the irrigation water quantity: ETGaugeOriginal Paper

Soil & Water Res., 2025, 20(4):219-233 | DOI: 10.17221/25/2025-SWR

Measuring the reference evapotranspiration (ET0) is difficult and costly. Some regions can have variable microclimates and these can often be quite far from climate stations. Therefore, it is optimal to use local measurements rather than a regionally calculated ET0. In this respect, one piece of equipment that provides cheap and reliable measurement results is ETGauge equipment. In this study, ET0 values measured with ETGauge equipment were compared with daily and monthly ET0 values calculated by five different commonly used empirical methods (ThornthwaiteAdj, Blaney-Criddle, Penman-Monteith = PM, Jensen-Haise and ASCE standardised Penman-Monteith = ASCE SZ PM). During the measurement period, daily ET0 values measured with ETGauge varied between 0–10 mm/day and the average was determined as 4.5 ± 2.7 mm/day in the study area. In the calculations made with the empirical models, the change in ThornthwaiteAdj is 1.3–6.6 mm/day with an average of 3.8 ± 1.6 mm/day, the change in Blaney-Criddle is 1.8–7.2 mm per day with an average of 5.1 ± 1.4, the change in PM is 1.2–10.5 mm/day with an average of 5.8 ± 2.7 mm/day, the change in Jensen-Haise was 5.8 ± 2.7 mm/day with an average of 5.5 ± 2.7 mm/day, and the change in ASCE SZ PM was calculated as 1.0–10.1 mm/day with an average of 5.4 ± 2.5 mm/day. Considering the obtained results, the ETGauge equipment can be used safely in creating irrigation programmes.

In addition to their practical importance as a medicinal plant, animal feed and a source of materials for the textile and construction industry, industrial varieties of Cannabis sativa L. (hemp in a wider sense) provide an alternative for controlling infectious diseases in livestock. Despite the genetic divergence between two primary groups of cannabis, i.e. medicinal cannabis and technical hemp, hemp plants also produce a wide spectrum of secondary metabolites. These include the main classes of cannabinoids and terpenoids, as well as representatives of flavonoids, stilbenoids, steroids, alkaloids, spiroindans, dihydrophenanthrenes, and lignanamides. Many of them exhibit antibiotic activity which can substitute or complement the use of traditional antibiotics in animal husbandry. For example, the cannabinoid fraction exhibits activity against the Gram-positive bacteria and some fungi. While the activity against Gram-negative bacteria is not characteristic of cannabinoids, these pathogens can still be affected by hemp terpenoids and flavonoids. The synergy among the secondary metabolite fractions or between the hemp metabolites and traditional antibiotics is also a favourable factor. The search for alternatives to traditional antibiotics is further driven by the increasing prevalence of genetically determined antibiotic resistance among veterinary pathogens, which poses the additional risk of transferring resistance traits to the human pathogens. The content of antibiotically active compounds in hemp can be enhanced through selection among existing genotypes, targeted breeding, cultivation conditions, and even by specific elicitation of secondary metabolites with the natural antibiotic function in the disease resistance of the plant. The switch to hemp metabolites is also supported by their compatibility as natural components of plant-based animal feed, and by favourable economic considerations.

Reference crop evapotranspiration (ETo) is a vital hydrological component influenced by various climate variables that impact the water and energy balances. It plays a crucial role in determining crop water requirements and irrigation scheduling. Despite the availability of numerous approaches for estimation, accurate and reliable ETo estimation is essential for effective irrigation water management. Therefore, this study aimed to identify the most suitable machine learning model for assessing ETo using observed daily values of limited input parameters in tropical savannah climate regions. Three machine learning models – a long short-term memory (LSTM) neural network, an artificial neural network (ANN), and support vector regression (SVM) – were developed with four different input combinations, and their performances were compared with those of locally calibrated empirical equations. The models were evaluated using statistical indicators such as the root mean square error (RMSE), coefficient of determination (R2), and the Nash-Sutcliffe efficiency (NSE). The results showed that the LSTM model, using the combination of temperature and wind speed, provided more reliable predictions with R2 values greater than 0.75 and RMSEs less than 0.63 mm·day–1 across all the considered weather stations. This study concludes that, especially under limited data conditions, the developed deep learning model improves the ETo estimation more accurately than empirical models for tropical climatic regions.

This study aimed to evaluate the effects of dietary administration of peppermint (Mentha piperita) alone and in combination with southernwood (Artemisia abrotanum) on performance, body and carcass composition, physicochemical characteristics, and amino acid composition of breast meat in broilers under Eimeria challenge. A total of 160 14-day-old male broilers (Ross 308) were randomly assigned to four dietary groups: the control (C) group was fed a basal diet; the CC group received a grower diet containing the coccidiostat robenidine; the M group was fed the diets with the addition of 20 g peppermint/kg of diet; the MS group was fed the diets with the addition of 10 g peppermint + 10 g of southernwood/kg of diet. The addition of peppermint to the diet increased final live weight compared to the CC group (P < 0.05). The highest value of dressing percentage was found in the M group as compared to the CC group (P < 0.01) and C group (P < 0.05). Compared with the C group, a higher intramuscular fat content was found in the breast meat of broilers in both the M and MS groups (P < 0.01; P < 0.05, resp.). Concerning the colour of meat, lower values for yellowness b* and chroma C* characteristics were observed in the C group compared to the MS group (P < 0.05) and mainly to the M group (P < 0.01). In spite of the lower crude protein content (P < 0.05) in the meat of the MS group, the highest content of all essential amino acids (P < 0.05) as well as the total content of all assessed amino acids (P < 0.01) were found in the meat of the MS group, resulting in a considerable increase in the nutritional value of the breast meat proteins of these broilers.

Recently, protected cultivation of bananas under subtropical conditions has gained popularity due to the impact of global climate change. Several factors influence the yield and quality of banana cultivation. Among these factors, variety plays an important role along with cultural practices. This study aimed to determine the performance of ‘Azman’, ‘Bango’, ‘Bonus’, ‘Grand Nain’, ‘Lider’, and ‘Paºa’ banana varieties in terms of morphological and yield characteristics under protected cultivation, as well as to elucidate the relationship between yield and factors affecting yield. The research was conducted between 2020 and 2022 in the Manavgat district of Antalya. The research findings showed that each morphological parameter examined varied significantly. However, the ‘Bango’ variety exhibited superior results in terms of finger circumference (13.23 cm), finger length (21.08 cm), bunch weight (39.33 kg), and yield per hectare (72 t/ha). Moderate to high-level phenotypic correlations were found between bunch weight and pseudo stem girth, pseudo stem height, number of fingers, finger weight, finger circumference, and finger length, with values of 0.544, 0.478, 0.326, 0.669, 0.581, and 0.543, respectively. Positive and significant phenotypic correlations were determined between finger length affecting export quality, bunch weight, finger weight, and finger circumference, with values of 0.543, 0.799, and 0.625, respectively. It can be concluded that the ‘Bango’ variety exhibited better results as compared to other varieties in terms of both yield and quality criteria. Additionally, positive phenotypic correlations were observed between bunch weight (which directly influences yield) and finger length (which affects export quality), as well as various morphological and pomological characteristics.

Salinity stress poses an increasing threat to global rice production, particularly under climate change. Enhancing salinity tolerance is crucial to sustain rice production and food security. This study aimed to assess genetic variation among rice parental genotypes and their derived crosses under salinity stress by evaluating physiological, biochemical, agronomic, and yield-related traits. Seven diverse rice genotypes were used to develop 21 crosses using a half-diallel mating design in the summer of 2023. The parental genotypes and their derived crosses were evaluated in the summer of 2024 under controlled greenhouse lysimeter conditions. Salinity stress was induced by irrigation with water containing 10.60 dS/m, and soil salinity was maintained at 9.60 dS/m through controlled irrigation and drainage. Twenty key traits were studied, including phenological and agronomic attributes, yield traits, and physiological and biochemical markers such as relative water content, leaf CO2 assimilation, proline accumulation, malondialdehyde content, and antioxidant enzyme activities, to assess salinity tolerance in rice genotypes. The results demonstrated highly significant variation among the evaluated parental genotypes and their derived crosses across physiological, biochemical, agronomic, and yield-related traits, indicating considerable genetic variability in the studied plant materials. The genotypes C9, R8, and R6 were identified as superior combiners contributing favourable alleles for salinity tolerance. Eleven promising F1 crosses exhibited enhanced growth, improved antioxidant enzyme activities, osmotic adjustment, reduced oxidative damage, and higher grain yield under salinity stress. Exploiting these plant materials can improve the development of novel rice genotypes tolerant of salt-affected environments, addressing the current challenges posed by climate change. Strong associations were observed among physiological, biochemical, agronomic, and yield-related traits, indicating an integrated network of responses that collectively contribute to enhanced salinity tolerance in rice.

Pyrenophora teres is a pathogen causing a net blotch disease in cultivated barley, which is present worldwide and can thus significantly reduce barley yields. This fungus also infects wild barley and other plants of the Hordeum genus, as well as barley grass, wheat, oats and plants from various genera, including Agropyron, Bromus, Elymus, Hordelymus and Stipa. Based on the symptoms it causes on the infected barley plants, the pathogen can be divided into two forms: P. teres f. teres, which causes net-like symptoms, and P. teres f. maculata, which causes blotchy symptoms. Infected seeds, stubble and plant debris, and volunteer and weed plants represent primary sources of pathogen inoculum. During the growing season, the pathogen enters a sexual stage, developing pseudothecia with asci and ascospores. This is followed by an asexual stage, during which conidiophores with conidia are formed. The conidial (anamorphic) stage is much more common, whereby conidia is a source of inoculum for secondary infection during the barley growing season. The first symptoms appear at the end of winter and the beginning of spring, often during the tilling phase. The most characteristic symptoms form on barley leaves. Frequently, symptoms of the net form can be mistaken for other diseases occurring on barley, making molecular analysis essential for accurate detection of P. teres, its forms, mating types and hybrids. Current net blotch control measures are based on the combined application of cultural, chemical and biological control methods and the selection of resistant varieties.

Evaluation of changes in dry matter and nutrient content during the growth dynamics of silage maizeOriginal Paper

Czech J. Anim. Sci., 2026, 71(3):129-139 | DOI: 10.17221/172/2025-CJAS

The aim of this study was to identify and quantify the relationships between the nutrient content and the DM (dry matter) content of various maize hybrids (Zea mays L.) in the dynamics of vegetative maturity and various soil-climatic growing conditions. Over the course of 7 growing seasons (years), a set of 1 972 samples of whole silage maize plants consisting of 206 different hybrids grown in two contrasting regions (lowland and foothill areas) was analysed. The focus was on DM content and the content of key energy nutrients (WSC – water soluble carbohydrates, starch, NDF – neutral detergent fibre) and their interactions. Results show that the transformation of WSC into starch has four key points: (i) it begins at a DM content of 150 g/kg; (ii) it peaks at a DM content of approximately 235 g/kg; (iii) it begins to decrease significantly from a DM content of 300 g/kg; and (iv) it practically stops rapidly after exceeding a DM content of 350 g/kg. In the dynamics of vegetative development of maize plants, the DM content is very closely related to the WSC content (R2 = 0.728) and the starch content (R2 = 0.873). With the gradual increase in vegetative maturity and DM content in maize plants, the transformation of WSC into starch dynamically increases. These characteristics, with small deviations, were also confirmed at different levels of evaluation (all analyses, regions, seasons and individual hybrids). These results show that a DM content of 300 g/kg to 350 g/kg can be considered the optimal harvesting window for maize ensiling and the optimal phase of silage maturity for whole maize plants, because once the DM content exceeds 350 g/kg; the transformation of WSC into starch stops and the drying phase of plants begins.

Autism spectrum disorder (ASD) is a group of human neurodevelopmental disorders with significant global prevalence. Deficits in social communication and interaction and repetitive, stereotyped patterns of behaviour characterise ASD. The aetiology of ASD is unclear, but several genetic and environmental risk factors, either alone or in combination, are implicated in its development. To date, the underlying pathogenic mechanisms of ASD remain incompletely understood due to its heterogeneity. To better understand the pathogenesis of ASD, various animal models have been developed. The use of animals in ASD research allows the exploration of the biological substrates of social behaviour, cognition, and reward sensitivity, which are key components of ASD symptoms. This review outlines the commonly employed animal models in ASD research and explores their applications and the associated challenges.

Silver nanoparticles (AgNPs) have attracted significant interest in veterinary medicine due to their unique properties, including enhanced stability, greater antimicrobial efficacy, and reduced toxicity compared to traditional silver salts. Their applications span various areas of veterinary practice, such as dermatology, wound management, infection prevention, drug delivery, and disinfection. This review explores their use in pigs, highlighting their role as feed additives to prevent diarrhoea, as antibacterial agents in semen extenders, and veterinary dermatology. AgNPs possess broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria, positioning them as a promising alternative to antibiotics in addressing antibiotic resistance. Additionally, AgNPs have shown antiviral potential, though the exact mechanism of action remains unclear. The review examines the antibacterial and antiviral properties of AgNPs, their utility in facility sanitation, and their potential toxicity to pigs. While AgNPs offer significant benefits in veterinary applications, concerns about their toxicity persist. Efforts to reduce this toxicity, such as surface modifications or combining AgNPs with other substances, are under investigation. Further research is essential to fully understand the potential applications and safety of AgNPs in pig medicine.

Decoupling of stomatal and mesophyll recovery drives photosynthetic resilience to water deficit in sugar beet: evidence from multiscale structural and functional traitsOriginal Paper

Water deficit severely constrains sugar beet productivity by impairing photosynthetic capacity. However, the underlying structure-function mechanisms conferring photosynthetic resilience remain poorly characterised. This study investigates the temporal dynamics of photosynthetic limitations and structural adaptations in sugar beet during water deficit and subsequent rehydration. We found that water deficit significantly reduced the maximum net CO2 assimilation rate (ANmax) and the Rubisco carboxylation rate (Vcmax) by impairing CO2 diffusion and biochemical processes. The reduction in photosynthetic capacity is primarily and stably attributed to mesophyll limitation, while contributions from stomatal and biochemical limitations flexibly change with deficit degree and rehydration. Severe water deficit caused irreversible structural damage that hinders recovery even after rehydration, while moderate water deficit allows partial restoration of leaf and chloroplast function. Partial least squares structural equation modelling (PLS-SEM) demonstrated that CO2 diffusion was governed by the volume fraction of intercellular air space (fias, β = 0.28) and surface areas of the chloroplasts exposed to leaf intercellular air spaces (Sc/S, β = 0.35), with Sc/S indirectly influencing mesophyll conductance (gm) through fias mediation (β = 0.53). Severe water deficit caused irreversible fias reduction and chloroplast interface damage (59% cell volume loss). These findings establish that resilience to water deficit in sugar beet depends on mesophyll structural integrity, with fias and Sc/S as key modulators of gm recovery. The study advances understanding of stress recovery mechanisms in sugar beet and provides a framework for multiscale crop improvement in the context of climate change.

The effectiveness of pheromone lures for Grapholita molesta (Busck 1916) from Propher (Czech Republic) and Pherobank (Netherlands), the attractiveness of green and transparent pheromone traps and the representation of non-target species were evaluated in three study areas of southern Moravia (Czech Republic) in 2019–2021 (24 traps per year). A total of 6 536 Grapholita molesta and 946 individuals of 17 non-target species were collected. Grapholita molesta was frequently captured in green delta traps with a Pherobank pheromone lure. Therefore, pheromone lures from different manufacturers have different efficacy and require the independent setting of harmfulness thresholds. An overview of non-target species recorded by other authors was compiled. Among the non-target species, morphologically similar species of Tortricidae dominated, causing considerable problems in the signalling of control measures of the target species.

Mungbean seeds [Vigna radiata (L.)] are easily damaged by insects during storage, and essential oils (EOs) have proved effective for controlling insect infestation. This research study assessed the bioactivity of EO from Jasminum sambac (L.) Aiton against Callosobruchus maculatus (F.). The chemical composition of EO was analysed by a gas chromatograph-mass spectrometer (GC-MS). All experiments were conducted following a completely randomised design (CRD) with four replications of the residual contact and seed dressing bioassays. Results indicated that J. sambac EO contained 35 compounds (97.587%), with the main component 3-hexen-1-ol benzoate. Residual contact toxicity LC50 values of this EO on adult C. maculatus at 24, 48, and 72 h were 5.01, 4.00, and 3.13 µL/mL, respectively. J. sambac EO at 8 µL/L showed the highest residual contact efficacy against C. maculatus, killing up to 100% in 72 hours. The highest concentration of J. sambac EO (1 mL/kg) gave optimal protection against C. maculatus within 4 and 5 days with 100% mortality. This concentration showed 100% inhibition of adult F1 progeny emergence, with no seed damage and weight loss of V. radiata L. after 30 days of exposure, and not significantly different from 0.8 mL/kg. Results indicated that J. sambac EO effectively prevented C. maculatus infestation and it could be used as an alternative to commercial chemical insecticides.

Czech J. Food Sci., 2024, 42(3):207-215 | DOI: 10.17221/164/2023-CJFS

Anthocyanins have received an increased attention not only because of its antioxidant activity; but because fortification of food products by minerals is important due to the lack of some minerals in population. The addition of these minerals can affect the sensorial and nutritional composition of food. The influence of calcium fortification on anthocyanins and colour changes in strawberry puree were assessed by accelerated storage test. The quantification of anthocyanins was performed by high-performance liquid chromatography with diode-array detection (HPLC-DAD) and colour changes were measured spectrophotometrically (CIE L* – lightness, a* – redness, b* – yellowness). The kinetical parameters (velocity constants and activation energies) were calculated. The activation energies of degradation of anthocyanins were calculated as pelargonidin-3-glucoside (26.24 ± 0.57, 21.18 ± 1.07, and 24.53 ± 1.33 kJ·mol–1), cyanidin-3-glucoside (16.10 ± 0.96, 11.61 ± 0.74, and 13.34 ± 1.72 kJ·mol–1), and pelargonidin-3-rutinoside (8.91 ± 0.17, 7.39 ± 0.98, and 8.23 ± 1.72 kJ·mol–1) of the control sample, calcium carbonate and calcium citrate respectively. The results showed that the addition of calcium salt had a statistically significant (P ≤ 0.05) effect on the degradation of anthocyanins.
