Responses of soil-inhabiting mesostigmatid mites to deforestation and disturbance in oak (Quercus brontii) forests of southwestern IranOriginal PaperAli Bagheri-Kordeshami, Jahangir Khajehali, Farshid Nourbakhsh, Masoud M. ArdestaniJ. For. Sci., 2021, 67(12):562-569 | DOI: 10.17221/54/2021-JFS The impacts of deforestation on edaphic mesostigmatid mites were investigated in oak forests of Lordegan, southwestern Iran, from April to October. A total of twenty-one species belonging to eighteen genera and ten families were collected and identified. The Shannon-Wiener, Simpson, Jaccard's and Margalef biodiversity indices were used for data analyses. Among the collected species, Antennoseius bacatus with 29% and Sessilunchus hungaricus with 16% relative abundance were the most abundant and dominant species in human-disturbed and natural forests, respectively. The estimated values were higher in natural oak forest than in disturbed and cultivated habitat. Significant differences were observed in soil nitrogen content and soil organic carbon between the two habitats, but not in pH values. Significant effects of sampling time and habitat were found on all four indices, but the effect of their interactions on these indices was not significant. It can be concluded that the changes in soil quality that resulted from deforestation may have a major role in reducing the soil mite density and related diversity indices in disturbed forests. |
Studies on some engineering properties of breadfruit (Artocarpus altilis) starch flourOriginal PaperWaliu Adewale Adebayo, Mercy Oluwakemi Ademiju, Dahunsi Olamide FajobiCzech J. Food Sci., 2025, 43(2):105-111 | DOI: 10.17221/40/2023-CJFS This research work evaluated some engineering properties of breadfruit starch flour following standard procedures with the aim of providing engineering data that would help its usage in food processed industries. Starch was extracted from matured breadfruit fruits, modified using acid and engineering properties were examined following standard procedures. Results of moisture contents, loose and packed bulk densities, density ratio and porosity were ranged from 8.23–9.13% dry basis (DB); 0.44–0.51 g·mL–1; 0.60–0.66 g·mL–1; 70.01–80.14% and 19.87–29.99%, respectively. Similarly, Carr index values ranged from 19.44–30.61% and Hausner ratio values ranged from 1.25–1.43, indicating that the flour samples investigated had poor (native), fair (modified) and good (potato) flow properties, using Carr index standard. Amylose, amylopectin and amylose-amylopectin ratio contents values ranged from 21.52–29.77%; 70.23–78.48% and 0.28–0.42%, respectively. Also, the flour samples thermal properties values using Differential Scanning Calorimeter (DSC) ranged from 106.4–129.09 °C; 31.93–78.36 °C; 106.2–175.75 °C; 214.90–278.6 J·g–1; 35.5–148.82 °C; 2.26–10.95 J·g–1·K–1; 0.305–3.0 (×10–6) W·m–1· °C–1, and 0.095–1.32 (×10–6) m2·s–1 for peak temperature, onset temperature, end temperature, enthalpy, temperature range, specific heat capacity, thermal conductivity and thermal diffusivity, respectively. Viscosity values as influenced by concentration and temperature ranged from 25.8–149 mPas for native starch and 41.9–109.6 mPas for modified starches. Hence, this research work provides engineering data that would help in process control, process design and bulk handling of breadfruit starch flour so as to promote its usage in food process industries. |
Understanding societal priorities for forest ecosystem services: Survey insights from 'Forestry Days 2024' in SlovakiaOriginal PaperZuzana Sarva¹ová, Jozef Pajtík, Zuzana Dob¹inskáJ. For. Sci., 2025, 71(4):195-204 | DOI: 10.17221/7/2025-JFS Understanding society's demand for forest ecosystem services (FES) is crucial for effective forest management and the development of supportive instruments, such as payments for ecosystem services (PES). This study surveyed visitors at 'Forestry Days 2024' in Slovakia through face-to-face questionnaires, capturing their views on FES and necessary management changes. Results show that regulating services and biodiversity are prioritised over cultural and provisioning FES. Respondents indicated a clear need for changes in forest management to reflect their FES preferences. Notably, perceptions of specific FES varied by gender, age, forestry background, and forest ownership but not by residence type. Public PES were considered the most acceptable policy for enhancing FES management, providing valuable insight for aligning public preferences with sustainable practices in Slovakia. |
Effects of two protein levels on the performance of chicken males with different growth intensitiesOriginal PaperJan Tyl, Eva Tùmová, Darina ChodováCzech J. Anim. Sci., 2025, 70(5):194-201 | DOI: 10.17221/44/2025-CJAS At present, genetic selection programs produce chicken genotypes with different growth intensities, which might have variable requirements for dietary protein. The objective of this study was to compare the response of three different genotypes to two levels of crude protein in feed mixtures. Cockerels of fast-growing Ross 308, medium-growing Hubbard JA 757 and slow-growing ISA Dual chickens were used in the study. Each genotype was fed diets that differed in protein level: the control group (C) received commercial feed, and the experimental group was fed a diet with a 6% lower protein content (LP). The daily weight gain (DWG) and feed conversion ratio (FCR) were significantly affected by the interaction of genotype and feed protein level. A greater percentage of DWG depression was observed in fast-growing cockerels than in medium-growing cockerels (10% and 6%, respectively), whereas the percentage of slow-growing cockerels negligibly increased (2%). A low-protein diet impaired the FCR only in fast-growing birds (–5%), whereas in the medium- (–2%) and slow-growing groups (+2%), the differences were not significant. Carcass composition significantly influenced only genotype and thigh meat pH. In terms of meat colour, significant interactions revealed that in fast-growing Ross 308 chickens, redness and yellowness did not differ according to diet group; however, in both genotypes with slower growth, significantly greater redness and yellowness were detected in the low-protein diet group than in the control group. The results indicate that genotypes with slower growth have lower protein requirements for growth performance, but lower diet protein has an effect on physical meat quality parameters in these genotypes. |

Valorisation of dragon fruit peel in drinking yoghurt: Development, physicochemical, proximate, functional properties, and shelf-life evaluationOriginal PaperMaryam Saeed Hafiz, Karunanayaka Mudiyanselage Imayuru Ushada Karunanayaka, Kartika Nugraheni, Ganwarige Sumali Nivanthi FernandoCzech J. Food Sci., 2025, 43(3):179-186 | DOI: 10.17221/21/2025-CJFS Dragon fruit peel (Hylocereus spp.), often discarded as waste has gained interest for its anti-aging, anti-inflammatory, and anti-diabetic properties. Peels make up to 22–44% (w·w–1) of the fruit's weight and this waste could make a significant effect on the environment. Therefore, this study aimed to develop a drinking yoghurt using dragon fruit peel extract as a natural colorant and evaluate its physicochemical, proximate, functional, and shelf-life properties. The sugar concentrations (4, 6, and 8% w·w–1) and incubation times (4, 6, and 8 h) were changed to optimise the product. Sensory evaluation by 30 semi-trained panellists using a 5-point hedonic scale identified 6% (w·w–1) sugar and an 8 h incubation as optimal. Compared to plain drinking yoghurt, the dragon fruit peel (DFP) drinking yoghurt showed higher crude fat (2.87%), fibre (0.72%), ash (0.66%), moisture (84.08%), total antioxidants (824.3 mg TE·100 g–1), flavonoids (0.22 mg QE–1·mL–1), and betalains content (0.0064 mg·mL–1). During storage, DFP yoghurt's pH declined, with minimal betalain loss, and it remained stable for three weeks at 4 °C without preservatives. This study demonstrates the potential of dragon fruit peel as a functional ingredient in yoghurt, offering nutritional and environmental benefits. |
Himalayan fir growth in central Bhutan reflects variability in temperature and precipitationOriginal PaperJiøí Lehejèek, Gabriel Vávrù, Sangay Wangchuk, Miroslav Svoboda, Katrien BoonenJ. For. Sci., 2025, 71(10):516-524 | DOI: 10.17221/58/2025-JFS Mountain ecosystems, especially those at the highest altitudes, are sensitive to current climate change. Proxy archives may provide an insightful tool to better understand ongoing changes and evaluate future scenarios. Trees have traditionally been used as such archives, as they often respond sensitively to environmental change. Thus, we studied tree-ring records of forest-line species Abies densa Griff. growing in the Eastern Himalayas, central Bhutan, to evaluate the effect of climate on the growth of this species. The annual chronologies were generated using standard dendrochronological methods and then compared with climatic data from the CRU TS database. The results demonstrate a negative effect of summer temperatures on the width of the annual rings, suggesting possible stress caused by higher temperatures during the monsoon season. On the other hand, a positive effect of temperatures on tree growth was observed during late winter months. The response to rainfall was mixed, with a positive effect on growth in November and a negative effect in May and January, suggesting a later onset of the vegetation season. To our knowledge, we present the first dendroclimatological study on this long-lived species in central Bhutan, portraying its potential for future climate and environmental research and applications. |
Sperm quality improvement of cryopreserved boar semen through colloidal centrifugation gradientOriginal PaperFrancisco Sevilla, Ignacio Araya-Zúñiga, Patricia Cervantes-Acosta, Antonio Hernández-Beltrán, Manuel Barrientos, Belisario Domínguez, Anthony ValverdeCzech J.

Screening of backfat thickness and musculus longissimus lumborum et thoracis depth of Aberdeen Angus cattle in Czech conditionOriginal PaperJaromír Ducháèek, Matú¹ Ga¹parík, Martin Ptáèek, Ludìk StádníkCzech J. Anim. Sci., 2021, 66(5):137-148 | DOI: 10.17221/274/2020-CJAS The aim of this study was to monitor the Czech Aberdeen Angus population for backfat thickness (BT), musculus longissimus lumborum et thoracis (MUSCLE) and live weight (LW) in relation to environmental and genetic conditions. In this study, we also wanted to display the potential for future inclusion of these parameters into national monitoring. Parameters of BT, MUSCLE and LW were measured at 120, 210, and 365 days of age in 769 Aberdeen Angus calves (417 bulls and 352 heifers) on seven farms. Statistical evaluation was performed in the SAS v9.3 software. The bulls achieved significantly higher (P < 0.01) weights and larger MUSCLE compared to the heifers, although the heifers had higher BT. The age of the dam at calving significantly influenced the growth ability of tested calves, but it did not influence BT nor MUSCLE. The nested effect of the year-season, farm and sire bulls (or genetic background) significantly affected LW, BT and MUSCLE of tested calves. The use of the same breeding bulls on different farms resulted in significant differences in growth parameters. Our results displayed the potential of nationwide monitoring of MUSCLE and BT of beef breeds, as official parameters of the beef performance testing in the Czech Republic. The inclusion of these globally used traits in the Czech breeding system would allow to predict breeding values for the Czech beef population. This would lead not only to general improvement of MUSCLE in the population, but also to the production of better breeding animals and slaughter animals with higher value. |
Effects of interspecific competition on crop yield and nitrogen utilisation in maize-soybean intercropping systemOriginal PaperLiang Feng, Wenting Yang, Quan Zhou, Haiying Tang, Qiaoying Ma, Guoqin Huang, Shubin WangPlant Soil Environ., 2021, 67(8):460-467 | DOI: 10.17221/665/2020-PSE Intercropping system plays a crucial role in improving crop yield, nitrogen utilisation efficiency (NUE) and economic benefit. The difference in crop yield and interspecific relationship under different bandwidth and row ratio allocation patterns are still unclear. A field experiment was carried out to explore change regularities between crop yield and interspecific relationships under maize soybean intercropping with different bandwidths and row ratios. The results showed that the yield of intercropped crops was lower than that of the sole crop. The nitrogen accumulation (NA), NUE and nitrogen competition ratio was the highest under the intercropping mode with a bandwidth of 2.0 m, which indicated that this mode was more conducive to the N uptake and utilisation in crops. In all intercropping systems, nitrogen equivalent ratio (NER) and land equivalent ratio (LER) were all greater than one, indicating that intercropping systems were conducive to improving land utilisation efficiency and NUE. Under the same bandwidth pattern, expanding the maize soybean row ratio from 2:4 to 3:4 was beneficial to the improvement of LER, NER, NUE, crop group yield. In conclusion, it was preferable in the NA, NUE, crop group yield under the system of bandwidth 2.0 m and row ratio 2:2, which could be a reference for maize soybean intercropping system. |
Effects of freeze-thaw on soil properties and water erosionReviewBaoyang Sun, Feipeng Ren, Wenfeng Ding, Guanhua Zhang, Jinquan Huang, Jianming Li, Lei ZhangSoil & Water Res., 2021, 16(4):205-216 | DOI: 10.17221/143/2020-SWR Freeze-thaw erosion occurs primarily at high latitudes and altitudes. Temperature controlled freeze-thaw events dislodge soil particles and serve as a catalyst for erosion. This review paper provided an overview of the effects of freeze-thaw on soil properties and water erosion. The process of freeze-thaw cycles results in temporary and inconsistent changes in the soil moisture, and affects the soil's mechanical, physical and chemical properties, such as the soil moisture content, porosity, bulk density, aggregates stability, shear strength and organic matter content and so on. The variation trend and range of the soil properties were related to the soil texture, water content and freeze-thaw degree. Furthermore, the soil erosion was affected by the freeze-thaw processes, as thawing and water erosion reinforce each other. However, research of different experimental conditions on indoor simulations have numerous limitations compared with field experiments. The use of indoor and field experiments to further reveal the freeze-thaw effect on the soil erosion would facilitate improved forecasting. |
The role of arbuscular mycorrhizal fungi in refining plant photosynthesis and water status under drought stress: a meta-analysisOriginal PaperMurugesan ChandrasekaranPlant Soil Environ., 2024, 70(8):502-508 | DOI: 10.17221/27/2024-PSE Due to increased climate change, crop productivity worldwide is in danger. Drought stress is considered one of the major environmental factors in relation to world food security. Previous studies showed that arbuscular mycorrhizal fungi (AMF) inoculation alleviates drought stress in various plants. However, whether AMF inoculation efficiency is based on gas exchange or water status and whether the effects differ among plants and AMF species remain unclear. To evaluate the effect of AMF on drought stress alleviation, a meta-analysis was conducted based on random-effect models accounting for effect size variation. Results revealed that photosynthetic rate had the highest effect size among gas exchange traits compared to stomatal conductance and transpiration rate. Our results also showed a significant positive impact on relative water content, water potential, and water use efficiency in AMF-inoculated plants compared to non-inoculated plants. Furthermore, among AMF species, Funneliformis mosseae, followed by Rhizophagus irrgularis, was an efficient AM fungi for drought stress alleviation. Therefore, this study suggests that a higher water use efficiency supports water transport to the leaf surface and keeps the stomatal opening, enhancing photosynthetic responses. |
Cytospora tristicha (De Not.) Mlèoch comb. nov., a lesser-known pathogen of wild rosesOriginal PaperPatrik Mlèoch, Michaela SedláøováPlant Protect. Sci., 2025, 61(1):56-65 | DOI: 10.17221/122/2024-PPS Stem canker of Rosa pendulina, collected in south-eastern Switzerland (canton of Graubünden) in August 2022, was studied in details. The causal agent of the disease was first identified as Valseutypella tristicha (Valsaceae, Diaporthales, Ascomycota) based on microscopic characteristics. The subsequent molecular analysis classified it into the genus Cytospora and indicated that it is identical with C. rosicola, described from China in 2020 based on the molecular data, however, V. tristicha is an older name than C. rosicola, so this has priority. Thus, a new combination of the name is proposed for this fungus. |
Gastroprotective effect of the hydroethanolic extract of geopropolis produced by Melipona subnitida (Meliponinae, Apidae) in Wistar ratsOriginal PaperJS Batista, TS Teofilo, HN Araujo Junior, NS Felix, KAR Paiva, TA Neves, LS Reboucas, GVD Medeiros, KMFM Costa (emaiVet Med - Czech, 2025, 70(4):134-142 | DOI: 10.17221/98/2024-VETMED

Camera systems and their user recognition reliability when entering an agri-food complexOriginal PaperJaroslav Mrázek, Jakub Vo¹áhlík, Eva Olmrová, Martin Pexa, Zdenìk Ale¹, Jakub ÈedíkRes. Agr. Eng., 2025, 71(2):105-112 | DOI: 10.17221/35/2025-RAE This study evaluates the efficiency of various facial recognition camera systems used to control access in agri-food production environments, focusing on their ability to identify individuals based on biometric facial traits. It is also important to prevent the movement of unwanted persons into the production premises in the agri-food complex. The main goal was to assess how these factors influence the recognition performance and to determine the most reliable system for preventing unauthorised entry. The results show notable performance disparities between the devices tested. It can be concluded in this research that there are statistically significant differences between the maternal, professional and semi-professional systems. The device that is most suited is the HIKVISION iDS-2CD8426G0/F-I, achieving the best average performance score. This is based on usual recognition times. These tests indicate that the HIKVISION DS-2DE7232IW-AE(S5), which obtained an average rating of 2.216789, is the second-best acceptable device. With a score of 2.842113, HIKVISION DS-2CD2H45FWD-IZS (2.8–12 mm) (B) received, without a doubt, the lowest ranking. Given the outcomes, systems with superior recognition capabilities like the iDS-2CD8426G0/F-I are best to use for critical access control applications and to also minimise the use of facial coverings in sensitive areas to ensure reliable identification and higher levels of security of agri-food complexes. |

Has contract farming improved the green technology efficiency of vegetable growers? Empirical evidence from rural areas in Shandong Province, ChinaOriginal PaperQi Li, Zixuan WangAgric. Econ. - Czech, 2025, 71(7):378-393 | DOI: 10.17221/43/2024-AGRICECON Contract farming is regarded as an effective strategy for smallholder farmers in developing countries to enhance their agricultural competitiveness. However, limited research exists on its potential to promote green, sustainable development. This paper investigates the impact of contract farming participation on farmers' green technology efficiency using data from a sample of 627 vegetable growers in Shandong, China and employs the propensity score matching method. Our findings are as follows: i) Under the counterfactual assumption, participation in contract farming increases green technology efficiency from 0.560 to 0.614. The efficiency of contract production bases, ranked from highest to lowest, is as follows: self-owned base, stock-sharing base, and contractual base. ii) The provision of productive services serves as a significant mediating factor in enhancing green technology efficiency, with a more substantial impact than issuing planned instructions. iii) Increasing purchase prices, as an effective means of providing motivational incentives, significantly amplifies the effect of contract farming on green technology efficiency in self-owned and stock-sharing bases. As organisational models evolve toward greater integration, the enhancing effect of price incentives on green technology efficiency strengthens. This study concludes with several public policy and agricultural management recommendations. |
Multi-year study monitoring the mercury content in the tissues of cattle sampled in the Czech Republic between 2014 and 2023Original PaperM Svoboda, V Vlasakova, D Harustiakova, J Illek, A Staffa, J Vasek, K Novotna Kruzikova, J Cahova, Z SvobodovaVet Med - Czech, 2025, 70(9):307-312 | DOI: 10.17221/34/2025-VETMED Analyses of mercury concentrations in the muscle, liver and kidneys of cattle were conducted in the Czech Republic during the period from 2014 to 2023. The average mercury content in muscles, livers, and kidneys of calves was 0.000 5 ± 0.000 0 mg.kg–1, 0.002 7 ± 0.000 5 mg.kg–1, and 0.004 1 ± 0.000 8 mg.kg–1, respectively. In fattening cattle, the average mercury content in muscles, livers and kidneys was 0.000 5 ± 0.000 0 mg.kg–1, 0.002 1 ± 0.000 2 mg.kg–1 and 0.004 9 ± 0.000 3 mg.kg–1, respectively. In cows, the average mercury content in muscles, livers and kidneys was 0.000 5 ± 0.000 0 mg.kg–1, 0.002 3 ± 0.000 1 mg.kg–1 and 0.006 9 ± 0.000 3 mg.kg–1, respectively. The maximum residual limit for human consumption was exceeded in 10 kidney samples (3 calves, 6 cows, 1 fattening cattle) and 1 liver sample (calf). In all age categories, the highest mercury concentrations were found in the kidneys, lower in the livers, and the lowest in the muscles. When comparing the age groups, significantly higher mercury concentrations were observed in the kidneys of cows than in calves and fattening cattle. It can be concluded that there is still a need for further monitoring of mercury concentrations in cattle tissues in the Czech Republic. |
Enhancing rheological properties of dough and quality of potato fibre-enriched breadOriginal PaperOmar Saleh, Hossam S. El-Beltagi, Abdelrahman R. Ahmed, Hefnawy Taha, Haiam O. Elkatary, Abdalla El‐Hadary, Hoda A.S. Farag, Mahmoud Sitohy, Ahmed Mahmoud Ismail, Ali OsmanCzech J. Food Sci., 2025, 43(6):462-469 | DOI: 10.17221/29/2025-CJFS This study investigates the effect of varying concentrations of potato fibre (PF) (1, 2, and 3%) on wheat flour (WF) dough rheological properties and the resultant pan bread quality. Chemical analysis, physical characteristics (weight, loaf volume, and specific volume), and colour attributes were estimated to assess bread quality. The impact of PF on bread sensory evaluation was estimated. The addition of PF significantly affected the properties of the dough. Moreover, the data indicated a substantial increase in water absorption (P ≤ 0.05) from 57.2% for the control to 65.5, 73.3, and 77.6% with the addition of 1, 2, and 3% PF to WF, respectively. Protein, crude fibre, and ash levels significantly increased (P ≤ 0.05) with higher PF ratios. Moisture and carbohydrate contents were markedly reduced (P ≤ 0.05). The specific volume considerably decreased from 3.15 cm3·g–1 in the control to 2.9, 2.74, and 2.53 cm3·g–1 with the addition of 1, 2, and 3% PF to WF, respectively. All replacement samples exhibited no significant alterations (P ≤ 0.05) in L* values and substantially (P ≤ 0.05) increased values of yellowness (b*) in all fortified samples relative to the control. Sensory assessments revealed that PF can be incorporated into WF at concentrations of 1% and 2% without compromising the overall acceptability of bread compared to the control. |
Effects of controlled irrigation on global warming potential based on CH4, N2O and CO2 fluxes in plateau paddy fieldOriginal PaperShufang Wang, Hongchun Bi, Liping Wang, Jing Wang, Ying Wang, Lihong ChenPlant Soil Environ., 2024, 70(9):535-542 | DOI: 10.17221/453/2023-PSE A suitable irrigation pattern is of great significance for reducing greenhouse gas emissions. In this study, field experiments and a denitrification-decomposition (DNDC) model were used to study the global warming potential based on CH4, N2O and CO2 fluxes under flooding irrigation and controlled irrigation in paddy fields in the Erhai Lake basin. The results showed that the average value of CH4 flux under controlled irrigation was lower than that under flooding irrigation, with a reduction range of 43.21% to 48.88%, however, the average value of the N2O and CO2 fluxes from paddy field under controlled irrigation were higher than those under flooding irrigation. Controlled irrigation patterns can significantly reduce the global warming potential in paddy fields based on CH4, N2O and CO2 fluxes. Controlled irrigation can effectively reduce the global warming potential per unit yield. For water management in the Erhai Lake basin, it is recommended the controlled irrigation treatment of soil moisture with an upper limit of 100% and a lower limit of 75–85% with irrigation, and a maximum surface water depth of 150–200 mm lasting for five days after precipitation from the jointing-booting stage to the milk stage. |
The insertion of an ancestral gene in Nicotiana tabacum plants reduces free radicals during saline irrigationOriginal PaperClaudia Marissa Calderón Torres, Victoria Abril Mancilla Galván, Miguel Murguía RomeroCzech J. Genet. Plant Breed., 2025, 61(1):43-49 | DOI: 10.17221/107/2024-CJGPB Transgenic organisms modified with ancestral genes for nitrogen metabolism are rare. Previously, it was reported that genetically modified Nicotiana tabacum with the ARO4 gene of aromatic amino acid synthesis from the yeast Debaryomyces hansenii increases its growth during moderate salt stress. In this investigation, it was explored if the changes in the expression of the gene DhARO4 in Nicotiana tabacum, during saline irrigation, are related to the chlorophyll content and the total reactive oxygen species production. Seedlings of transgenic and wild type Nicotiana tabacum germinated in standard conditions were divided into two irrigation groups, with 100 mM of NaCl and with tap water; and, after 50 days, in the non-senescent adult leaves of the plants, the total chlorophyll a and b and the total chlorophyll content were determined by spectrophotometry and the reactive oxygen species production (•OH, 1O2, H2O2) was quantified by a 2',7'-dichlorodihydrofluorescein assay. The expression of the DhARO4 gene was verified with a salt shock of 100 mM of NaCl for 24 hours in the transgenic and wild type plants in the tap water irrigation group. The DhARO4 gene transcript increased (P < 0.05) in the transgenic plant; meanwhile, the average concentration of chlorophyll a increased (P < 0.05), and the average production of reactive oxygen species decreased (P < 0.05). |
Whole-genome resequencing data reveal the genetic diversity of local chickens in southern Zhejiang and surrounding areas in ChinaOriginal PaperYawen Zhang, Bo Zhang, Ziwei Li, Fengxiang Hou, Yan Zhao, Junjie Jin, Bin Song, Wenjie GuCzech J. Anim. Sci., 2025, 70(3):113-120 | DOI: 10.17221/186/2024-CJAS China’s local chicken breeds, especially those in the Zhejiang Province, are rich in genetic diversity owing to environmental heterogeneity and complex ecosystems. Distinctive local breeds have emerged through long-term natural selection and domestication. We investigated the genetic diversity and population structure of local chickens in southern Zhejiang and surrounding areas using whole-genome resequencing of 129 chickens from seven populations. A total of 1.8 terabytes of raw data was obtained, and 4 802 728 single nucleotide polymorphisms were detected. The Xianju chicken population exhibited the highest genetic diversity, while Yandang Partridge chickens were genetically distant from other chicken breeds. This study provides valuable information for conserving poultry genetic diversity and informs about breeding programmes of local Chinese chicken breeds. |
Biocontamination in the dairy industry: The effect of raw milk conditioning film on the adhesion of Escherichia coliOriginal PaperZakariyae El hafa, Ikhlas Hani Chennoufi, Hafida Zahir, Mostafa El louali, Hassan LatracheCzech J. Food Sci., 2025, 43(2):112-117 | DOI: 10.17221/91/2024-CJFS Conditioning films on surfaces employed in the dairy industry serve as the precursors to the formation of pathogenic biofilms that impact product quality and consumer safety. Conditioning films have been studied from several aspects. However, there has been no study that evaluated the effect of raw milk conditioning film on the adhesion of Escherichia coli. This study investigated the adhesion of E. coli on glass and stainless-steel surfaces conditioned with raw milk and explored the surface properties potentially influencing this adhesion using the contact angle method. The results showed that after treating surfaces with raw milk, the adhesion of the bacteria on stainless steel and glass was significantly altered. Adhesion increased significantly on stainless steel (from 0.55 log10 to 2.8 log10) but it decreased on glass (from 1.56 log10 to 0.8 log10). Significant alterations were observed in the physicochemical properties of the surfaces. Glass was initially relatively hydrophilic (46.33°), while stainless steel was relatively hydrophobic (82.5°). After treatment, the glass became relatively more hydrophobic (74.6°), and stainless steel became relatively more hydrophilic (69.4°). The electron donor/acceptor components of glass decreased after the treatment, while these components increased for stainless steel. The significant changes in adhesion were hypothesized to be due to the modification of surface properties by the raw milk. |

Climate change and topographic variations affect infestation by Xyleutes ceramica (Walker, 1865) (Lepidoptera: Cossidae) in teak plantations in ThailandOriginal PaperThanapol Choochuen, Jiøí Foit, Ponthep Meunpong, Warong SuksavateJ. For. Sci., 2025, 71(6):297-311 | DOI: 10.17221/15/2025-JFS The teak bee-hole borer [Xyleutes ceramica (Walker, 1865)] is considered one of the most serious pests of teak (Tectona grandis) in Thailand. The present study investigates climatic and topographic variables affecting the infestation of teak trees by X. ceramica in 10 plantations and predicts the risk of infestation by the species under current and future climatic conditions in Thailand. At each plantation, 48 plots evenly distributed among twelve teak stands were sampled. The infested teak trees in the plots were assessed, and the coordinates of the tree positions were recorded. The maximum entropy (MaxEnt) model was used to assess the effects of environmental factors and predict the occurrence probability of the species using current and projected (2050) climate data based on the Shared Socioeconomic Pathways SSP1-2.6 and SSP5-8.5 scenarios from multiple global climate models. According to our results, high accuracy values [AUC (area under the curve) = 0.852, TSS (true skill statistics) = 0.775] of the model prediction were obtained, and the infestation was found to be driven much more by climate than by topographic characteristics. Above all, X. ceramica was found to prefer moderate temperatures in a highly distinct seasonal climate. Additionally, relatively low amounts of premonsoon rainfall are also found to be favoured by the species. The predicted risk map revealed that the northern region is the core area of X. ceramica infestation in Thailand under current and future climatic conditions, but the severity of infestation is predicted to gradually decrease under the predicted future climatic conditions. Recommendations for management to minimise tree damage caused by X. ceramica are also presented in this study. |
Unveiling green perception effect: How live streaming scenes and green information influence purchase intention of prepared dishesOriginal PaperShuo Hao, Pei Li, Nannan Zhang, Yang Du, Rui Liang, Ziyang LiuAgric. Econ. - Czech, 2025, 71(10):537-549 | DOI: 10.17221/247/2024-AGRICECON To promote the sustainable consumption of prepared dishes, this study examines how green attribute information (GAI) and live streaming scenes experience (LSSE) influence consumers' green perceptions (GP) – including perceived green value (PGV) and perceived green trust (PGT) – and subsequently affect their purchase intention (PI). A green perception model was developed and tested using a mixed-method approach. Word cloud analysis was conducted on consumer comments collected from e-commerce platforms to extract key descriptors and concerns, which informed the design of a structured questionnaire. A total of 291 valid responses were analysed using partial least squares structural equation modelling (PLS-SEM). Results show that: (i) GAI does not directly impact PI, indicating that GP is a necessary mediator; (ii) GAI significantly influences PGV, but not PGT; (iii) GP fully mediates the GAI–PI relationship, although PGV has a negligible direct effect on PGT; (iv) LSSE significantly enhances both GP and PI; (v) GP partially mediates the LSSE–PI relationship. These findings highlight the dual role of LSSE in facilitating information adoption and emotional engagement, and suggest that enhancing LSSE design and enriching GAI are effective strategies to increase consumers' green perception and purchase intention towards prepared dishes. |

Adverse effects of cadmium on poultry and role of selenium against it: An updated reviewReviewMohamed Ketta, Eva Tùmová, Roman Stupka, Jaroslav Èítek, Darina ChodováCzech J. Anim. Sci., 2021, 66(9):339-348 | DOI: 10.17221/86/2021-CJAS Cadmium (Cd) is a toxic heavy metal, discharged into environments naturally or anthropogenically, where industrial and agricultural revolutions have led to serious Cd pollution into the environment. Poultry feed may be contaminated by Cd due to its presence in concentrates and supplements, and also in the machinery and equipment used in feed production and processing. After absorption in the digestive system, Cd largely accumulates in kidneys, liver, bones and other organs and causes irreversible damage to these organs. Higher doses of Cd in the poultry diet reduced feed intake, body weight, bone mineral density, egg production and eggshell quality. Selenium (Se) is an essential micronutrient and important component of a variety of antioxidant enzymes, with the ability to antagonize metal toxicity including Cd. Hence, in the current review, we try to summarize recent information about the toxicological effects of Cd and provide updated information about the role of Se as an effective strategy in reducing Cd toxicity in poultry. |

Impact of different factors degrading cork oak stands in the Mediterranean region: A case study from AlgeriaOriginal PaperSalah Eddine Younsi, Yasmine Adjami, Rym Ghanem, Billel Bouchaib, Mohamed Laid OuakidJ. For. Sci., 2021, 67(12):570-581 | DOI: 10.17221/77/2021-JFS In recent years, the cork oak forests that characterise the Mediterranean region have been exposed to various factors that result in their degradation. These cork oak trees, due to increasingly accentuated anthropogenic activity, undergo withering at different scales.The objective of the study is to assess the impact of various factors that degrade cork oak forests in the Mediterranean region located in northeastern Algeria, and this was achieved by prospecting 22 sampling locations. This allowed the creation of a database containing 745 trees that were observed and 27 measured variables. Different readings were then taken into consideration based on measurements and sometimes on ratings. The impact of several biotic and abiotic factors, which affect and damage the health of cork oak, was identified. These factors include in particular the infestations by xylomycetophagous insects such as Platypus cylindrus and Xyleborus sp., which can potentially infest the cork oak trees that we observed one year after bark harvesting. On the other hand, the stationary descriptors such as altitude, slope, exposure, etc., are important for the dendrometric and exploitation characteristics, but their unfavourable values do not necessarily lead to tree mortality; for example, medium to low slopes, associated with average altitudes of 600 m a.s.l., may ensure the healthiest trees like in our case study. Finally, we were able to find that certain decline factors may affect a particular category of trees, either because they are older, taller or have a large girth, or because they are subject to inadequate debarking. |
