Development of a seroprevalence map for Mycoplasma gallisepticum in broilers and its application to broilers from Comunidad Valenciana (Spain) over the course of two years (2009-2010)Original PaperC. Garcia, J.M. Soriano, P. Catala-GregoriVet Med - Czech, 2016, 61(3):136-140 | DOI: 10.17221/8764-VETMED The aim of this study was to design and implement a Seroprevalence Map based on Business Intelligence for Mycoplasma gallisepticum (M. gallisepticum) in broilers in Comunidad Valenciana (Spain). To obtain the serological data we analysed 7363 samples from broiler farms over 30 days of age over the course of two years (3813 and 3550 samples in 2009 and 2010, respectively, from 189 and 193 broiler farms in 2009 and 2010, respectively). Data were represented on a map of Comunidad Valenciana to include geographical information of flock location and to facilitate the monitoring. Only one region presented with average ELISA titre values of over 500 in the 2009 period, indicating previous contact with M. gallisepticum in broiler flocks. None of the other regions showed any pressure of infection, indicating a low seroprevalence for M. gallisepticum. In addition, data from this study represent a novel tool for easy monitoring of the serological response that incorporates geographical information. |
Pneumatosis coli in a dog - a serial radiographic study: a case reportCase ReportT.S. Hwang, Y.M. Yoon, S.A. Noh, D.I. Jung, S.C. Yeon, H.C. LeeVet Med - Czech, 2016, 61(7):404-408 | DOI: 10.17221/255/2015-VETMED A 12-year-old intact female poodle was presented with a history of an acute episode of tenesmus and passage of ribbon-shaped stools. Anaemia, leucocytosis, hypoalbuminaemia, hyperglycaemia, and elevated ALP were found. Faecal floatation and wet mount preparation were negative for parasites. Anaerobic faecal culture resulted in a heavy growth of Clostridium. Survey abdominal radiographs revealed extensive intramural emphysema of colon and rectum. Ultrasonography of the abdomen revealed bright echoes within the layers of the colon wall, confirming the accumulation of intramural gas. Abdominal computed tomography revealed extraluminal gas tracking along the colon and the rectum. Based on the radiographic, ultrasonographic, and computed tomographic findings, the present case was diagnosed as pneumatosis coli with an underlying cause of bacterial overgrowth. The patient was treated with antibiotics for seventeen days. Clinical signs were resolved after three days of treatment. Decreased intramural gas accumulation was evident during radiography of the abdomen performed at fourteen days after the initial evaluation. Therefore, pneumatosis coli should be considered when a dog is presented with clinical signs of colitis. |
Relation between selected indicators of forest stand diversity and quality of timber production in managed Central European forestsOriginal PaperJ. Merganič, K. Merganičová, R. Maruąák, L. Tipmann, L. ©álek, L. Dragoun, R. StolarikováJ. For. Sci., 2016, 62(3):97-106 | DOI: 10.17221/94/2015-JFS The present study examines the relationship between the quality of timber production and the species and structural diversity of forest stands. The data used came from a regional forest inventory of the University Forest Enterprise "Kostelec nad Černými lesy", Czech Republic. The inventory was performed from 2009 to 2011 on 1,188 sample plots that represented 86 strata defined by the combination of three variables: site (5 categories), age (12 categories) and canopy cover (5 categories). On each sample plot, we quantified 171 partial biodiversity indicators that represented species or structural diversity. The quality of timber production was specified by four indicators quantified using local assortment tables. In total, we analysed 58,824 univariate linear regressions describing the relationships between diversity indicators and timber quality in individual strata. The results revealed that their relationship changes with stand age. The proportion of the best-quality assortments increases with the increasing species richness in all age categories. |
Predicting the earthwork width and determining the annual growth loss due to forest road construction using artificial neural network and ArcGISOriginal PaperS. Peyrov, A. Najafi, A.R. NourodiniJ. For. Sci., 2016, 62(7):337-344 | DOI: 10.17221/110/2015-JFS The area of forest destruction as well as the annual growth loss due to road construction before constructing a road was predicted. To do this, road cross sections of 88 points along the 10 km proposed road were predicted using Multilayer Perceptron Neural Network with two input parameters of hillside slope and rock share within MATLAB software. Then according to the predicted width, the area of road earthwork as well as the area of roadside with a 10 m width was calculated in ArcGIS software. Finally, by overlaying the inventory network layer on the road map and by knowing the annual growth (m3) for each plot the growth loss of the area of road earthwork was calculated and one-third of the annual growth increment was considered to calculate the growth loss of the roadside. According to the results, for the construction of a 10 km long road in the region, 12.98 ha of forest area is destructed due to road construction, of which 5.36 ha is destructed resulting from earthwork operations and 7.61 ha occurs in the roadside and its growth is influenced by road construction. With the construction of the road, in total, 32.606 m3 of growth will be lost annually, of which 22.221 m3 is due to road earthwork that is completely removed from the forest annual growth cycle and 10.384 m3 of the growth loss belongs to the roadside which is decreased resulting from road construction. |
Postulation of seedling stem rust resistance genes of Yunnan wheat cultivars in ChinaOriginal PaperTian-ya LI, Xian-xin WU, Xiao-feng XU, Wan-lin WANG, Yuan-yin CAOPlant Protect. Sci., 2016, 52(4):242-249 | DOI: 10.17221/137/2015-PPS To determine stem rust resistance genes of wheat varieties in Yunnan province, 11 Chinese strains of Puccinia graminis f.sp. tritici with different virulence and 1 artificial mutant strain were used in 110 wheat varieties. The results indicated that among the 45 Sr genes, Sr31, Sr5, SrTmp, Sr30, Sr36, Sr8a, Sr11, Sr24, Sr29, Sr34, Sr9e, Sr26, Sr38, Sr47, and SrTt3 were characterised in 55 wheat varieties singly or in combination. Sr5, Sr31, SrTmp, Sr36, and Sr30 were contained in 17, 16, 5, 5, and 3 cultivars, respectively. Six cultivars contained Sr24 and/or Sr34. Three plant materials likely contained one or more of Sr8a, Sr11, Sr34, and Sr23 genes as well as other unknown genes. The 16 immune or highly resistant varieties contained one or more of Sr9e, Sr26, Sr38, Sr47, SrTt3, and other unknown resistance genes. The reaction types on 22 of the tested cultivars were different from those on Sr genes tested, and their resistance genes could not be analysed. Additionally, 17 varieties were susceptible to all the tested strains, having no postulation value. Our study provides a basis for improved breeding of stem rust resistant wheat in China. |
Effect of osmotic stress on growth and osmolytes accumulation in sugar beet (Beta vulgaris L.) plantsOriginal PaperG.-Q. Wu, R.-J. Feng, Q.-Z. ShuiPlant Soil Environ., 2016, 62(4):189-194 | DOI: 10.17221/101/2016-PSE To investigate the effects of osmotic stress on plant growth, and ions and compatible solutes accumulations of sugar beet (Beta vulgaris L.), in the present study, two-month-old plants were subjected to different degrees of osmotic stress (-0.5, -1.0, and -1.5 MPa) induced by sorbitol for 7 days. The results showed that fresh weight and water content in both leaf blade and leaf petiole significantly decreased by osmotic stress. With the increase of osmotic stress, Na+ concentration in leaf blade showed the significantly increasing trend. However, osmotic stress significantly reduced K+ concentration in lateral root. It was observed that osmotic stress of -1.5 MPa remarkably increased sucrose accumulation in storage root compared to control. In addition, plants accumulated more sucrose and fructose in storage root than in other tissues. Proline concentrations in leaf blade, leaf petiole and storage root significantly increased by osmotic stress of -1.0 MPa and -1.5 MPa; in leaf blade it was to a higher degree than in leaf petiole and storage root. These results suggested that sugar beet plants can adapt to osmotic stress by accumulating more osmolytes, such as Na+, sucrose and proline. |
Maternal immunity induced by inactivated S. Typhimurium vaccine is less protective to S. Derby challenge than to S. Typhimurium challenge in suckling pigletsOriginal PaperJ. Gebauer, A. Osvaldova, H. Kudlackova, M. Maceckova, F. Sisak, H. Havlickova, P. Ondrackova, L. Leva, M. Faldyna, J. MatiasovicVet Med - Czech, 2016, 61(1):23-27 | DOI: 10.17221/8679-VETMED Salmonella enterica serovar Typhimurium and Salmonella enterica serovar Derby are the most common serovars of Salmonella enterica ssp. enterica found in pigs in Europe. We previously observed that suckling piglets of sows vaccinated with an S. Typhimurium-based inactivated vaccine are protected against homologous strain challenge. To develop this vaccine for commercial use, potential crossprotectivity of this vaccine to challenge with S. Derby was tested. Two sows were vaccinated with an S. Typhimurium-based inactivated vaccine while two other sows remained serologically negative. Four-day-old suckling piglets from both groups were orally challenged with S. Derby or S. Typhimurium. Maternally-derived immunity against S. Typhimurium protected piglets against S. Typhimurium challenge, when a significant (P < 0.05) decrease in S. Typhimurium count was found in ileocaecal and submandibular lymph node, tonsil, ileum and ileum content. On the other hand, after S. Derby challenge, significant (P < 0.05) decrease in S. Derby count was detected only in ileum content. Although both serovars belong to the same O:4 serogroup, other antigenic structures, for example the flagellin, are different. In a subsequent in-vitro experiment, we found that serum from vaccinated sows inhibited the motility of S. Typhimurium but not the motility of S. Derby. Our results indicate that protectivity of S. Typhimurium vaccine against S. Derby infection is limited. |
Cross border protection of the clusters' intellectual property in the agricultural sectorOriginal PaperMirjana KRANJAC, Uroą SIKIMIĆ, Marija VUJAKOVIĆ, Istvan MOLNARAgric. Econ. - Czech, 2015, 61(1):23-30 | DOI: 10.17221/130/2014-AGRICECON The goal of the paper is to analyse the potential for the innovation of cross border clusters from the sector of agriculture. The methodology which is used is the research of intellectual property (IP) of the clusters' members and clusters by using a specific questionnaire for clusters in two countries: Hungary and Serbia. The analysis of results shows a high level of innovativeness within the clusters' members and the need of protection of their intellectual achievements. The similar results were achieved in both countries. They show that the IP rights at the level of clusters should be protected as the cross border trademark and the name of origin. The scientific contribution of this paper is to introduce the concept of the joint cross border IP protection for two or more clusters from different countries which might be applied across the EU. |

Fermented buttermilk-based beverage: impact on young volunteers' health parametersFood Analysis, Food Quality and NutritionRaimondas Narkevičius, Arvydas Kaminskas, Jonas Algis Abaravičius, Dalius Vitkus, Valerija Jablonskienė, Dalia SekmokienėCzech J. Food Sci., 2016, 34(2):143-148 | DOI: 10.17221/344/2015-CJFS The technology of a functional fermented buttermilk-based beverage was developed and the impact of beverage consumption on the health parameters of young volunteers was studied. Three functional beverages were made on the basis of buttermilk, which differed in the composition. The beverage containing the buttermilk-skimmed milk-milk protein concentrate (0.3%) as a product with the preferred quality characteristics (synaeresis, viscosity, sensory properties, and acceptability) was used for further studies regarding the impact on human health. The medical nutrition experiments did not show any statistically significant effect on the biochemical blood parameters of 25 young volunteers after a 21-day period of the consumption of fermented buttermilk beverage with milk protein concentrate, although some of them (e.g. total, low- and high-density cholesterol, triacylglycerol concentrations, etc.) slightly decreased. The anthropometric and body composition, arterial blood pressure, and pulse evaluation indicators of recipients did not change significantly. |
Collie eye anomaly: a reviewReviewA. PalanovaVet Med - Czech, 2015, 60(7):345-350 | DOI: 10.17221/8381-VETMED Collie eye anomaly (CEA) is an inherited congenital visual impairment with heterogeneous signs. The first symptoms are already visible in the early embryo. Among the most affected breeds are Collies and Shetland Sheepdogs but the disease has spread to different breeds depending on the country of origin. Dogs affected with this disease share a 7.8 kb deletion in intron 4 of the NHEJ1 gene. Inheritance of this disease is autosomal recessive with incomplete penetrance. Thanks to a commercially available genetic test breeders can identify genetically affected recessive homozygotes and clinically healthy but genetic carriers of the mutation and thus select healthy parents for the next generation of dogs. However, the exact cause of the disease is not known and it is not known whether the causative mutation influences the occurrence of some other diseases (e.g. immunodeficiencies). |
Biomass combustion emissionsOriginal PaperV. Kaľimírová, R. OpáthRes. Agr. Eng., 2016, 62(10):S61-S65 | DOI: 10.17221/69/2015-RAE The paper deals with gaseous emissions generated in biomass combustion in water boilers. It provides results of analyses of gaseous emissions and boiler efficiency in combustion of branches of apple trees from spring pruning, spruce cuttings and corn cobs obtained from kernel harvest. Measurements were done in laboratory conditions. Average CO emission values observed in combustion were from 334.7 to 650.18 mg/m3 and average NOx emission values were low, between 50.1 and 157.2 mg/m3. Boiler efficiency in applewood combustion was lower - this was caused by its higher moisture. |
Prevalence of systemic disorders in cats with oral lesionsOriginal PaperB. Dokuzeylul, A. Kayar, M.E. OrVet Med - Czech, 2016, 61(4):219-223 | DOI: 10.17221/8823-VETMED Oral disorders of small animals constitute a problem for veterinarians. Chronic oral infections are commonly seen in domestic cats. The objectives of this study were to characterise feline oral lesions, common feline dental problems, and especially the association of oral disease and systemic disease in cats. Two hundred and twenty cats referred over a period of 33 months to the Internal Medicine Department of our University with signs of oral disorders were included in this prospective study and were examined for the occurrence of the most commonly seen diseases. Infectious diseases which frequently cause ulcers and/or erosions within the mouth and on the tongue, constituted a significant proportion of the cases identified in this study. Feline Coronavirus (FCoV) infection was diagnosed in 36 cats (16%), Feline Calicivirus (FCV) in 17 cats (8%) and 16 cats (7%) had three viral infections (FCoV + Feline Immunodeficiency Virus (FIV) + Feline Leukemia Virus (FeLV)) at the same time. We conclude that oral disorders may be a sign of underlying systemic diseases in cats, especially in those diagnosed with feline viral infections. Other diagnosed diseases included immune-mediated disorders, eosinophilic granuloma complex, gastrointestinal system disorders, nutritional disorders, diabetes mellitus, hepatic disorders and chronic renal failure. Therefore, the first step in preventing oral disease in animals must be routine physical examination which includes a comprehensive oral exam. |
Effects of acetylsalicylic acid on coagulation tests and haptoglobin concentrations in rabbits with permanent transvenous pacingOriginal PaperI. Uhrikova, P. Scheer, J. Hlozkova, P. Suchy Jr., M. SepsiVet Med - Czech, 2016, 61(9):528-532 | DOI: 10.17221/22/2016-VETMED The aim of this study was to evaluate changes in coagulation tests, haptoglobin concentrations and leukocyte counts in rabbits with right-ventricle pacing medicated with acetylsalicylic acid (ASA). Blood was collected from 35 non-anaesthetised males from the jugular vein at baseline, one and two months after pacemaker implantation. Animals were divided into two groups: non-medicated and medicated with ASA. Total leukocyte and platelet counts were measured on an automatic veterinary flow cytometry haematological analyser. Prothrombin time, activated partial thromboplastin time, fibrinogen levels and D-dimers were determined from citrated blood. We found significantly elevated activated partial thromboplastin times and prothrombin times in ASA in comparison to the control group, but not within the ASA group over time. We also observed a decrease in platelet counts in the control group over time, but not in comparison to the ASA group. No significant changes in total leukocyte counts and haptoglobin concentrations were detected. Medication with ASA may alter coagulation profiles in rabbits with permanent transvenous pacing. |
In vitro regeneration of Pistacia vera L. from nodal explantsOriginal PaperB. Benmahioul, M. Kaïd-Harche, F. DaguinJ. For. Sci., 2016, 62(5):198-203 | DOI: 10.17221/82/2015-JFS To enhance the induction of shoots, the excised nodes were cultured on Murashige and Skoog medium containing different cytokinins and various concentrations. The best conditions for shoot induction and growth were with 6-benzyladenine at 1.0 mg.l-1. For axillary shoot proliferation, the excellent result was obtained using 2.0 mg.l-1 meta-topoline. Well-developed shoots (more than 2 cm in length) were successfully rooted ex vitro at 82% by treatment with commercial rooting powder (2% indole-3-butyric acid; Rhizopon®). Rooted plantlets were acclimatized in the greenhouse and the survival rate of transplantation reached 80%. |
The use of products containing a phage in food industry as a new method for Listeria monocytogenes elimination from food (Listeria monocytogenes phages in food industry) - a reviewReviewDamian Pietracha, Anna MisiewiczCzech J. Food Sci., 2016, 34(1):1-8 | DOI: 10.17221/217/2015-CJFS Increased detection records of Listeria monocytogenes in foods have been recently observed. Standard methods of L. monocytogenes elimination from food products including pasteurisation or acidification may, however, be unreliable. The elimination of L. monocytogenes using specific bacteriophages which are natural antagonists of these pathogenic bacteria has become an innovative method that does not affect the taste, smell or appearance of the product. The use of phage preparations in food production is becoming an increasingly popular method for the effective and safe elimination of L. monocytogenes from food products. |
Tillage effect on soil organic carbon, microbial biomass carbon and crop yield in spring wheat-field pea rotationOriginal PaperS. Yeboah, 4, R. Zhang, L. Cai, L. Li, 3, J. Xie, 3, Z. Luo, J. Liu, 3, J. WuPlant Soil Environ., 2016, 62(6):279-285 | DOI: 10.17221/66/2016-PSE This research was conducted to assess the influence of long-term tillage system on soil organic carbon, microbial biomass carbon, root biomass and crop yield in spring wheat-field pea rotation fields in a rainfed semi-arid environment from 2013 through 2015. The treatments were; conventional tillage with stubble removed (T); no-till with stubble removed (NT); no-till with stubble retained (NTS) and conventional tillage with stubble incorporated (TS) arranged in a randomised complete block design with three replicates. The soil organic carbon in NTS increased by 16% and 14% over T and NT. Compared with the T and NT, NTS increased soil microbial biomass carbon by 42% and 38% in 0-30 cm depth, respectively. Root biomass was significantly increased in NTS by 47% and 54% over T and NT, respectively. Across the three years, NTS had an average grain yield of 53% and 41% higher than T and NT, respectively. Compared with NTS, T and NT decreased root biomass by 54% and 48%, respectively. In view of the limited and erratic biomass production in this region, integration of no-till with straw mulching is recommended for soil fertility improvement, environmental quality and sustainable crop production. |
Genome-wide analysis of CpG islands in some livestock genomes and their relationship with genomic featuresOriginal PaperA. Barazandeh, M.R. Mohammadabadi, M. Ghaderi-Zefrehei, H. Nezamabadi-pourCzech J. Anim. Sci., 2016, 61(11):487-495 | DOI: 10.17221/78/2015-CJAS CpG islands (CGIs) are an important group of CpG dinucleotides in the guanine- and cytosine-rich regions as they harbour functionally relevant epigenetic loci for whole genome studies. As a matter of fact, since there has not been a formal comparative analysis of CGIs in domestic even-toed ungulate genomes, this study was performed to serve this comparison. The Hidden Markov Model was used to detect CGIs in the genomes. The results indicated that the CGIs number and CGI densities had scant variations across genomes. The goat genome had the highest number of CGIs (99 070), whereas the alpaca genome had the highest CGI density (43.39 CGIs/Mb). Significant positive correlations were observed among CGI densities with chromosome pair number, observed CpG/expected CpG, recombination rate, and gene density. When the size of chromosomes increased, the CGI densities decreased and a trend of higher CGI densities in the telomeric regions was observed. Only 10.96% of CGIs were methylated underscoring this postulation that the majority of CGIs remains to be unmethylated. The highest amount of the methylated CGIs was observed in the introns, intergenic, and coding (CDS) regions and the lowest amount of the methylated CGIs was observed in the promoter regions, implying that the DNA methylation of CGIs may control gene expression at the genome level. Detected differences between even-toed ungulate and other vertebrate genomes showed that CGI densities varied greatly among the genomes. These findings would contribute to better understanding the even-toed ungulate (epi) genomes, the role of CGIs in epigenomic functions and molecular evolution. |

MarinoVet Med - Czech, 2015, 60(5):288-291 | DOI: 10.17221/8182-VETMED A rare case of a liver biliary duct cystoadenoma in a dog is reported. Tissue changes are described with an emphasis on immunohistochemical patterns that aid in the identification of the tumour and differentiation from similar macroscopical features that arise due to congenital abnormalities. Finally, we provide hints on comparative pathology. |
The effects of monosodium l-glutamate administration on the reproduction and serum biochemistry of adult male rabbitsOriginal PaperC.N. Okoye, I.S. Ochiogu, C.E. OnahVet Med - Czech, 2016, 61(3):141-147 | DOI: 10.17221/8765-VETMED In this study the effects of monosodium l-glutamate (MSG) administration on the reproductive parameters and serum biochemistry of male rabbits were investigated. Sixteen mature male New Zealand mixed-breed of rabbits (Oryctolagus species) weighing 1.1-1.65 kg were used for this study. They were randomised into four groups of four rabbits each. Group A which served as the untreated control, received only distilled water while Groups B, C and D which were the treated groups, received 0.25 g/kg, 0.5 g/kg and 1 g/kg body weight of MSG from a 40% MSG stock solution. The MSG was administered to the rabbits by oral gavage every forty-eight hours for a period of eight weeks. Serum levels of luteinising hormone (LH), testosterone, total cholesterol and total protein, and activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were evaluated on Days 14, 28 and 56 of MSG administration. Results showed that when compared to the untreated group (Group A), on Day 56 of MSG administration the mean serum levels of both LH and testosterone were significantly (P < 0.05) lower in Group D that received 1 g/kg body weight MSG, while the serum cholesterol levels of Group C rabbits that received 0.5 g/kg body weight MSG was significantly (P < 0.05) lower on Day 28 of MSG administration. The mean serum ALT activity of Groups B and C rabbits were significantly (P < 0.05) lower on Day 56 of MSG administration, while the mean serum AST activity of the Group D rabbits was significantly (P < 0.05) higher on Day 14 of MSG administration. There were no significant (P > 0.05) variations in the mean serum total protein between the groups. Testicular histomorphology revealed that MSG administration did not affect the testes of the rabbits as there was no obvious testicular histopathology. It was concluded that administration of MSG to male rabbits significantly lowered serum LH, testosterone and cholesterol levels and serum ALT activity without affecting testicular histomorphology. |
Pectus excavatum in a cat: a case reportCase ReportR. Yaygingul, B. Kibar, I. Suner, A. BelgeVet Med - Czech, 2016, 61(7):409-411 | DOI: 10.17221/285/2015-VETMED This case report aims to clinically and radiologically describe a case of feline pectus excavatum and to evaluate the treatment results. An 8-month-old female cat weighing 3.2 kg was presented to the Surgery Clinic, Faculty of Veterinary Medicine, Adnan Menderes University with respiratory distress. Following radiographic and clinical examinations, the condition was diagnosed as pectus excavatum. Surgical correction was performed using a U-shaped external splint. Post-operative thoracic radiography showed that the concavity of the sternum was reduced. The splint was removed five weeks post-surgery. Two months after surgery, the cat was clinically normal. |
The assessment of forestry companies in the Czech Republic with focus on profitabilityOriginal PaperM. Levá, H. Čermáková, M. Stárová, H. VostrovskáJ. For. Sci., 2016, 62(3):116-125 | DOI: 10.17221/88/2015-JFS The paper deals with the evaluation of economy of forestry companies. The evaluation stems from the results of economic analyses of enterprises that are further monitored in the context of forestry and development of economic financial ratios of evaluated companies. Furthermore, the evaluation is based on real possibilities of companies stemming from resources which they have at their disposal and on the facts that occurred in the selected companies in the monitored period. The development of important factors influencing the whole branch of forestry and their real state are introduced in the first part of the paper. After that, methods used in financial analysis of enterprises are described. The fact that forest land in the Czech Republic covered 2.66 million hectares in 2014 and its proportion in the total area of the country is 34% adds importance to the topic (Czech Statistical Yearbook 2015). |
Values and professional and ethical norms in rural tourism in PolandOriginal PaperJan SIKORA, Wlodzimierz KACZOCHA, Agnieszka WARTECKA-WAZYNSKAAgric. Econ. - Czech, 2015, 61(8):377-392 | DOI: 10.17221/14/2014-AGRICECON With development of the market economy, the views concerning the importance of ethical norms in business activity are developing. Ethical orientation in economics, has been popularized for several decades by e.g. French centre "Economie et Humanisme"1, established by a renowned Dominican, L.J. Lebret. Tourism, including rural tourism, represents an economic activity which has its specific ethical dimension. The goals of this paper are to characterize the basic values that are voluntarily accepted and used in tourism in rural areas in Poland and to identify the ethical norms that guarantee the realization of these values. The authors adopted the basic values-goals that should be recommended in rural tourism. They also formulated specific professional and ethical norms that support realization of the values, which include: humanity and standards for realizing the principle of humanity; the cultural and material conditions of living in rural areas; economic activity, including tourist activity that improves rural living conditions; innovative attitudes towards modernization and improving the quality of rural tourist services; and values that support the development of sustainable tourism in rural areas. The theoretical investigations concerning axiological problems were supplemented with the results obtained from a national-level empirical survey that was conducted in rural areas in Poland. |
Accuracy of Structure from Motion models in comparison with terrestrial laser scanner for the analysis of DBH and height influence on error behaviourOriginal PaperD. Panagiotidis, P. Surový, K. KuľelkaJ. For. Sci., 2016, 62(8):357-365 | DOI: 10.17221/92/2015-JFS With the advantage of Structure from Motion technique, we reconstructed three-dimensional structures from two-dimensional image sequences in a circular plot with a radius of 6 m. The main objective of this research was to clarify the potential of using a low cost hand-held camera for evaluation of the stem accuracy reconstruction, through the comparison of data from two different point clouds. The first cloud comprises data collected with a digital camera that are compared with those collected by direct measurement of the FARO® Focus3D S120 laser scanner. Photos were taken in a circular plot of pine trees using the stop-and-go method. We estimated the Euclidean distance for corresponding points for both clouds and we found out that most of the points with error less than 11 cm are concentrated mainly on the ground. Regression analysis showed a significant relationship between height above ground and error, the error is more pronounced for points located higher on the stems. As expected, no dependence was found between the error of the points and the diameter at breast height of their respective stems. |
Length of prematurity period in wheat cultivars determines maximum cereal aphid abundanceOriginal PaperMartina Trávníčková, Kateřina Pánková, Zdenka Martinková, Alois HoněkPlant Protect. Sci., 2016, 52(4):254-261 | DOI: 10.17221/3/2016-PPS Maximum aphid numbers on wheat are positively related to the length of the period elapsed from immigration to the population peak. We predicted that maximum abundances on late maturing cultivars would be greater than on early ones. This was tested using 8 spring wheat cultivars that differed in the length of time to senescence. In a 4-year experiment, numbers of aphids were checked at weekly intervals. Maximum abundances on late-maturing cultivars were significantly greater than those on early cultivars. However, the length of the vegetation period affected maximum abundances less than did the annual variation in aphid abundance. Genetic disposition for early ripening thus tends to decrease aphid numbers, but manipulation of this character is unlikely to become an important source of aphid resistance. |

Food Sci., 2016, 34(5):406-413 | DOI: 10.17221/322/2015-CJFS The fucoidans were obtained by extraction with water and gradient precipitation with different concentrations of ethanol. The main structural characterisations and bioactivities were achieved. Four fractions of water-soluble crude fucoidans with different molecular weights - SPC60, SPC70, SPH60, SPH70 - were extracted from S. pallidum collected from the Yellow Sea, China, using cold water and hot water extraction, and fractional precipitation with gradient concentrations of ethanol. Chemical analysis demonstrated that all of these fucoidan fractions consisted of fucose, rhamnose, xylose, mannose, glucose, and galactose with different monosaccharide mole ratios. Fractions SPC60, SPC70, and SPH70 showed moderate cytotoxic activity against P388 murine leukaemia cells. Fucoidan is a kind of bioactive polysaccharide from the brown algae. This study provides a fast and feasible method to obtain fucoidans from S. pallidum, which can be used as pharmaceutical material and functional food. |
Effect of long-term differential application of inorganic fertilizers and manure on soil CO2 emissionsOriginal PaperH.S. Dhadli, B.S. BrarPlant Soil Environ., 2016, 62(5):195-201 | DOI: 10.17221/266/2015-PSE Carbon dioxide (CO2) fluxes from agricultural soils have been considered as one of the important environmental impact issue, due to their role in global warming and also its mitigation by carbon (C) sequestration in soils. Substantial scope of C sequestration with the application of inorganic fertilizers and manures has been reported, but the long-term effects of continuous application need to be critically examined. To study the effect of continuous differential application of NPK fertilizers and farmyard manure (FYM) in maize-wheat cropping system, CO2 fluxes were measured via closed chambers and gas chromatography in a long-term experiment in progress for the past 42 years. The average daily CO2 fluxes differed significantly amongst various treatments and were 55, 26 and 92% higher in NPK, N and NPK + FYM treatments over the control in the maize crop season and 43, 8 and 83% in the wheat crop season. Highly significant correlation of CO2 emissions was found with soil organic carbon and total nitrogen in the maize and the wheat crop seasons. Although, CO2 emissions were higher from long-term inorganic fertilizers and FYM treatments, still they are environmentally sustainable management practices, as they increased soil fertility and crop yields which consequently resulted in higher atmospheric CO2 capture by plants and carbon sequestration in soils. |
Field performance of potato minitubers produced in aeroponic cultureOriginal PaperK. RykaczewskaPlant Soil Environ., 2016, 62(11):522-526 | DOI: 10.17221/419/2016-PSE The aeroponic system is a viable technological alternative for potato minituber production within a potato tuber seed system. The aim of the study was to evaluate the productivity of potato minitubers grown in aeroponic culture and collected in 14 successive periods of the growing season. The minitubers of cvs. Ametyst and Tajfun were tested in an experimental field after a storage period. It was found that cv. Ametyst was characterized by higher yield and number of tubers than cv. Tajfun. Yield of cv. Ametyst averaged 42.6 t/ha, and cv. Tajfun 37.3 t/ha. The number of tubers over 3 cm of cv. Ametyst averaged 644.2 per ha, and cv. Tajfun 437.7 per ha. The yield and number of tubers was dependent on the physiological age of minitubers harvested on successive dates. Comparing the productivity of minitubers grown in aeroponics and in the soil, a significant difference was found in the number of tubers with a transversal diameter over 3 cm. There were more daughter tubers from minitubers grown in soil. They are the result of different-size minitubers used for planting, smaller ones from aeroponics and larger from soil. |
Effects of dietary Enterococcus faecium on growth performance, carcass characteristics, faecal microbiota, and blood profile in broilersOriginal PaperM. Mohammadi Gheisar, A. Hosseindoust, I.H. KimVet Med - Czech, 2016, 61(1):28-34 | DOI: 10.17221/8680-VETMED This research was performed to evaluate the effect of supplementing broiler diets with a probiotic containing Enterococcus faecium on growth performance, carcass characteristics, faecal microbiota, and blood profile. A total of 384 one-day-old Ross 308 broiler chicks (mixed gender) with an average initial BW of 39.2 g were used in a 35 days feeding trial. The chicks were allotted to pens with 16 birds per pen and eight replications per treatment with food and water provided ad libitum. Treatments were: (1) basal diet, (2) 0.25% probiotic, and (3) 0.5% probiotic. Results indicated that body weight gain (BWG) on Day 7 to 21, Day 21 to 35 and overall (0 to 35) increased (P < 0.05) linearly but feed intake (FI) and feed conversion ratio (FCR) were not affected. A linear increase (P < 0.05) was observed in the relative weight of breast muscle when comparing the 0 to 0.5% concentration of probiotic, but breast meat colour was not affected by treatments. A significant impact (linear effect, P < 0.05) was observed on drip loss on Day 1. Inclusion of probiotic decreased (P < 0.05) the count of Salmonella linearly but the counts of E. coli and Lactobacillus were not affected. There was no remarkable influence on blood profile. Thus, it was concluded that inclusion of a probiotic containing Enterococcus faecium improved growth performance and altered the intestinal microbial population, without any negative effects on meat colour and blood profile in broiler chickens. |
Repair of flail chest using interfragmentary wiring and stability augmentation with basket-weave fashion sutures in a toy breed dog: a case reportCase ReportS. Ahn, S. Jeong, H. YoonVet Med - Czech, 2016, 61(6):348-352 | DOI: 10.17221/33/2016-VETMED We report here the clinical presentation and successful surgical management of flail chest caused by bite wounds in a toy breed dog. Surgery was decided on, based on physical, radiographic and computed tomography (CT) examination findings which included thorax deformity, inward displacement of the end of a fractured rib and suspected lung injuries. Interfragmentary wiring, basket-weave fashion sutures and latissimus dorsi flap for thoracic wall reconstruction were performed to correct the flail chest and augment the thoracic wall stability. There was no evidence of respiratory distress 16 months post-operatively. This is the first case report describing detailed clinical information together with computed tomography evaluation and a successful surgical procedure to correct flail chest in a toy breed dog using interfragmentary wiring and basket-weave fashion sutures. |
