Eggshell structure, measurements, and quality-affecting factors in laying hens: a reviewReviewM. Ketta, E. TůmováCzech J. Anim. Sci., 2016, 61(7):299-309 | DOI: 10.17221/46/2015-CJAS Eggshell quality is one of the most significant factors affecting poultry industry; it economically influences egg production and hatchability. Eggshell consists of shell membranes and the true shell that includes mammillary layer, palisade layer, and cuticle. Measurements of eggshell quality include eggshell weight, shell percentage, breaking strength, thickness, and density. Mainly eggshell thickness and strength are affected by the time of egg components passage through the shell gland (uterus), eggshell ultra-structure (deposition of major units), and micro-structure (crystals size and orientation). Shell quality is affected by several internal and external factors. Major factors determining the quality or structure of eggshell are oviposition time, age, genotype, and housing system. Eggshell quality can be improved through optimization of genotype, housing system, and mineral nutrition. |
Clinical ultrasonography in loggerhead sea turtles (Caretta caretta): imaging of pathological featuresOriginal PaperM. De Majo, F. Macri, M. Masucci, G. Coci, M.G. PennisiVet Med - Czech, 2016, 61(3):155-161 | DOI: 10.17221/8767-VETMED Ultrasound scans were used to image pathological features in sea turtles. Scans were carried out in 19 loggerhead sea turtles, weighing from 2 to 21 kg, during the course of clinical examinations using 3.5 and 7.5 MHz sector transducers. The examination was performed after placing turtles in dorsal recumbency. Turtles were manually restrained and, in order to find the most suitable acoustic windows, were held down either by their heads (left and right cervicobrachial windows), front flippers (left and right axillary windows) or back flippers (left and right prefemoral and postfemoral windows). The right and left cervicobrachial windows allowed visualisation of the liver and gallbladder; the stomach was localised through the left prefemoral acoustic window; the intestinal loops were observed through the left and right prefemoral acoustic windows; the bladder was identified through both prefemoral acoustic windows. The pathological findings were as follows: idiopathic ileus, an intestinal linear foreign body and smooth muscle hypertrophy, presence of calculi and sediment in the gallbladder. These results highlight the importance of ultrasound examination along with clinical examination in sea turtles for the evaluation of coelomic pathologies. |
Historical development of land ownership in the Czech Republic since the foundation of the Czechoslovakia until presentShort CommunicationLudek HOMOLAC, Karel TOMSIKAgric. Econ. - Czech, 2016, 62(11):528-536 | DOI: 10.17221/250/2015-AGRICECON The aim of the paper is to describe the land ownership relations in the area of the current Czech Republic since the foundation of Czechoslovakia. The description of the history of changes of land ownership in the Czech Republic is important for the perception of the current nature of the land use and land market. Land use and ownership was always related to the historical context and political regime. The time periods are divided by the important historical events: after 1918 (foundation of the Czechoslovak Republic), 2nd World War period, after 1948 (takeover of the power by the Communist Party of Czechoslovakia and the centrally planned economy period) and after 1989 (foundation of the market economy). During this era, three land reforms took place. The main role was played by the political apparatus the aim of which was to enhance its economic and political influence, and international interests. It can be concluded that the ownership of land in the Czech lands was always uneven. During the period, the state expropriated land from different society spheres and reallocated it to others. No other property in private ownership underwent so many ownership changes in the legal organization of the state. |
Inhibiting effect of shallow seed burial on grass weed emergenceOriginal PaperDonato Loddo, Vasileios P. Vasileiadis, Roberta Masin, Maria C. Zuin, Giuseppe ZaninPlant Protect. Sci., 2016, 52(1):64-69 | DOI: 10.17221/78/2015-PPS The efficacy of superficial tillage as a sustainable tool to reduce the emergence of Digitaria sanguinalis, Setaria viridis, and Sorghum halepense was evaluated with field experiments. Seeds were buried at 1, 2, 5, and 10 cm of depth to simulate seed vertical distribution caused by autumn superficial tillage. Seedling emergence was monitored weekly for two years after sowing. The highest emergence was obtained in the first year after sowing and from 1 and 2 cm. Sorghum halepense was only slightly affected by seed burial, with 15% of emergence from 10 cm of depth, while D. sanguinalis was strongly affected, with 4% of emergence from 5 cm. The efficacy of superficial tillage as control tool could vary according to local weed flora. |
Determination of plant-available micronutrients by the Mehlich 3 soil extractant - a proposal of critical valuesOriginal PaperJ. ZbíralPlant Soil Environ., 2016, 62(11):527-531 | DOI: 10.17221/564/2016-PSE Soil testing in the Czech Republic is based on the use of the Mehlich 3 method for determination of macronutrients and diethylentriaminepentaacetic acid (DTPA) and hot-water extraction for determination of micronutrients. Since inductively coupled plasma optical emission spectrometers have become commonly used in soil testing laboratories, Mehlich 3 extractant could be used very effectively also for a simultaneous micronutrient determination. To take full advantage of the universal Mehlich 3 extractant, new criteria for evaluation of the content of micronutrients in this extractant are needed. The criteria presented in this study were obtained by a simple calculation of criteria from the relationships between the Mehlich 3 extractant and the extraction methods for which the criteria were available (DTPA for copper, zinc, manganese, iron and hot-water extraction for boron). The first calculated estimates of the criteria were pre-validated and slightly adjusted to minimize the difference between the frequency of the samples in each category after determination and evaluation by the compared methods. Further adjustment of the presented critical values with respect to the field and pot experiments will be necessary in the future. |
Biomass combustion emissionsOriginal PaperV. Kažimírová, 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. |
Environmental and social value of agriculture innovationShort CommunicationMarie KUBANKOVA, Miroslav HAJEK, Alena VOTAVOVAAgric. Econ. - Czech, 2016, 62(3):101-112 | DOI: 10.17221/58/2015-AGRICECON New requirements regarding agriculture production together with the increased pressure on environmentally friendly practices leave almost no space for the routine agriculture production. Innovations that include environmental changes are therefore essential. Agricultural research faces various challenges associated with the quality and effectiveness of agriculture production and recently also with the environmental and sustainability issues. The paper provides a case study focused on the environmental and social evaluation of a biological asset that constitutes an agricultural innovation. This paper also shows a concrete example of how the social and environmental reporting can be constructed and implemented by providing an evaluation of a Bumblebee Nest. As a result, the total value consisting of the market, ecosystem and aesthetic value is provided. Although the market value comprises the largest proportion of the total value, it does not exceed 64%. |
Monitoring infestations of oak forests by Tortrix viridana (Lepidoptera: Tortricidae) using remote sensingOriginal PaperLeila Gooshbor, Mahtab Pir Bavaghar, Jamil Amanollahi, Hamed GhobariPlant Protect. Sci., 2016, 52(4):270-276 | DOI: 10.17221/185/2015-PPS We tested the suitability of Landsat images to track defoliation by insect herbivory with focus on the oak leaf roller, Tortrix viridana (Lep.: Tortricidae). Landsat images from the period before (2002) and after the T. viridana infestation (2007, 2014) were compared in oak forests of Zagros in western Iran. The Normalised Difference Vegetation Index (NDVI) was calculated for the test area from Landsat 5, 7, and 8 images. Because the red and near-infrared spectral bands of Landsat 8 OLI sensors are different from the other two, a model for the calibration of Landsat OLI NDVI was developed. The proposed model with a correlation coefficient of 0.928 and root mean square error of 0.05 turned out to be applicable and the NDVI decreased significantly during the observation period. Taking into account the protection status of the area and small fluctuations in temperature, the decrease in NDVI could be attributed to T. viridana damage. |
Heavy metals in the common carp (Cyprinus carpio L.) from three reservoirs in the Czech RepublicFood Analysis, Food Quality and NutritionPetra Vičarová, Hana Dočekalová, Andrea Ridošková, Pavlina PelcováCzech J. Food Sci., 2016, 34(5):422-428 | DOI: 10.17221/100/2016-CJFS Toxic metals (cadmium, lead, and mercury) in the tissues of common carp fished from three reservoirs (Pilská, Domaninský, and Matějovský) in the Bohemian-Moravian Highlands were measured in the period from April 2013 to September 2014 and the risk of consuming the fish from these localities was evaluated. During this project 25 fish specimens from each locality were analysed. The concentration of metals in muscle tissue and liver was determined by atomic absorption spectrometry. A variation in the content of heavy metals in fish samples and fish tissues was demonstrated and discussed. Higher concentrations of cadmium in the fish tissue were found in 50 samples of carp liver. Because the fish liver is not commonly consumed, common carp from the Moravian-Moravian Highlands does not pose any health risk for consumers. Concentrations of the other monitored toxic metals in fish tissue were low and were complying with the maximum residue limit in all cases. |
15N isotope tracing of nitrogen runoff loss on red soil sloping uplands under simulated rainfall conditionsOriginal PaperH.J. Zheng, J.C. Zuo, L.Y. Wang, Y.J. Li, K.T. LiaoPlant Soil Environ., 2016, 62(9):416-421 | DOI: 10.17221/246/2016-PSE Stable isotope 15N tracer technique was used in combination with artificial rainfall simulation to study the influence of interflow and surface-flow on nitrogen (N) migration loss of soil-plant systems on typical red soil sloping uplands. This study also investigated the utilization efficiency of fertilizer N during different peanut plant growth stages. The results indicated that soil N loss was predominantly via interflow and erosive sediment. Fertilizer N loss during the initial growth stage was mainly through surface runoff, while that occurred as interflow increased from less than 5% to around 16% during the middle and late growth stages. The loss of fertilizer N through surface runoff, erosive sediment and interflow accounted for over 18% of the total N application. The utilization rate of fertilizer N by peanut plants was around 45% through its life cycle, and that 70% of N absorbed by this plant derived from the soil. This highlighted the importance of adopting effective methods to reduce nutrient loss through interflow and surface-flow, the need to increase the utilization rate of fertilizers, and the importance to maintain soil fertility at a relatively high level. |
An approach to mapping the potential of cultural agroecosystem servicesOriginal PaperJarmila MAKOVNÍKOVÁ, Jozef KOBZA, Boris PÁLKA, Jozef MALIŠ, Radoslava KANIANSKA, Miriam KIZEKOVÁSoil & Water Res., 2016, 11(1):44-52 | DOI: 10.17221/109/2015-SWR A system for evaluating outdoor recreation as a cultural agroecosystem service is presented. Every agroecosystem presumably has the potential for providing some kind of outdoor recreation. Two approaches to mapping the recreation potential were used and compared - the Social Values for Ecosystem Services (SolVES) model and the regional model (RegMOD). From the possibilities of recreation activities, hiking, biking, and cross-country skiing were chosen. The comparison of the two approaches showed that the RegMOD incorporates a wider range of categories than the SolVES model, particularly for hiking. The robust character of the SolVES model is reflected by narrowing the spectrum of categories of this recreation activity. The differences in the map view are marked in the case of biking and cross-country skiing. Overall, the grasslands of the study area in Slovakia offer mainly medium relevant capacity (53.90% by the results of the SolVES, 64.90% by the results of the RegMOD) for providing selected outdoor recreation activities. The less productive (53.88% of all non-productive grasslands by the results of the SolVES, 48.00% by the results of the RegMOD) and non-productive grasslands represent a higher relevant capacity (41.18% of all non-productive grasslands by the results of the SolVES, 54.40% by the results of the RegMOD) for providing outdoor recreation activities. This brings about a new view of their management as well as use. The RegMOD developed in this paper is replicable and could be applied by managers mainly at the regional level on condition of their proficiency in geographical information systems. |
Origin and distribution of the brachial plexus in the Spix's yellow-toothed cavy (Galea spixii Wagler, 1831) (Rodentia, Caviidae)Original PaperH.N. Araujo Jr, G.B. Oliveira, A.V.N. Silva, R.E.M. Oliveira, F.V. Camara, C.M. Oliveira Jr, F.V.F. Bezerra, M.F. OliveiraVet Med - Czech, 2016, 61(6):337-343 | DOI: 10.17221/206/2015-VETMED Due to the absence of literature on the brachial plexus in the Spix's yellow-toothed cavy, this study was conducted to examine the origin and neural distribution of this rodent's brachial plexus. Ten adult animals obtained from previous experiments were thawed, fixed in 10% formalin solution for 72 h and then dissected. Cotton blocks soaked in 2% hydrogen peroxide were placed on the ventral roots of the plexus. Photographs of the most representative specimens were taken and schematic sketches were prepared to illustrate the results. The Spix's yellow-toothed cavy's brachial plexus primarily originated from the ventral roots of the sixth (C6), seventh (C7) and eighth (C8) cervical nerves and from the first two thoracic nerves (T1, T2), and less frequently from C6-T1 or C6-T3. The peripheral nerve trunks of the Spix's yellow-toothed cavy's brachial plexus are the following: suprascapularis (C6-C7), axillaris (C6-C7), subscapulares (C6-C7), cranial pectoral (C6-C7), musculocutaneous (C7-C8), radialis (C7-T2), medianus (C7-T2), ulnaris (C7-T2), pectorales caudales (C7-C8), thoracicus longus (C7-C8), thoracicus lateralis (C7-T2) and thoracodorsalis (C7-T2). |
Impact of climatic conditions on the reproductive phenological phases of European hazel (Corylus avellana L.) in SlovakiaOriginal PaperJ. ŠkvareninováJ. For. Sci., 2016, 62(2):47-52 | DOI: 10.17221/55/2015-JFS The work presents the results of phenological observations of flowering and fruit ripeness of the European hazel (Corylus avellana L.) in Slovakia in two time periods: 1964-1983, and 1994-2013. The phenological stations at elevations from 100 to 875 m a.s.l. were grouped to 7 elevation zones, each 100 m wide. In the first studied period, flowering started on 19 March on average, while in the second period it started 5 days earlier. The average duration of flowering equal to 7-9 days did not depend on the elevation, but on the air temperature and weather patterns in the different elevation zones. During the first period, the average elevation gradient of flowering was 5.6 days per 100 elevation meters, while in the second period it was reduced to 3.5 days in the entire elevation profile. In the elevation zones between 300 and 500 m, a high correlation (P < 0.01) between the onset of flowering and elevation was reduced to a moderate level of correlation due to changing environmental conditions. In 1994-2013, the ripeness of hazel nuts started on average on 30 August in Slovakia, showed low variability and moderate correlation with elevation. The phenological elevation gradient was 2.9 days per 100 m of elevation. |
Influence of chestnut flour addition on quality characteristics of pasta made on extruder and minipressFood Technology and Economy, Engineering and Physical PropertiesIndira Kosović, Marko Jukić, Antun Jozinović, Đurđica Ačkar, Daliborka Koceva KomlenićCzech J. Food Sci., 2016, 34(2):166-172 | DOI: 10.17221/451/2015-CJFS Durum semolina was replaced with 10, 15, and 20% of chestnut flour. Pasta was produced on a single screw extruder with the temperature profile of 80/90/90°C and on a laboratory minipress. Pasta samples were dried at room temperature and physical and sensory properties were determined. Generally, the chestnut flour addition to durum wheat pasta decreased optimum cooking time, hardness, cohesiveness, and chewiness, but increased cooking losses and pasta adhesiveness. Samples made on an extruder showed shorter optimum cooking times in relation to samples made on a minipress. Absorbed water was decreased with chestnut flour addition. Pasta made on an extruder showed a higher sensory score in comparison with pasta made on a minipress. The addition of chestnut flour influenced the colour of the samples. Samples made on an extruder showed darker colour in dried and cooked pasta samples in relation to minipress samples. In dried pasta samples, the extruder gave yellower samples in relation to the minipress, while in cooked pasta samples it was reversed. Overall, the extruder gave higher-quality pasta compared to the minipress. |
The effect of cover crops on the fungal and bacterial communities in the soil under carrot cultivationOriginal PaperE. Patkowska, M. Błażewicz-Woźniak, M. Konopiński, D. WachPlant Soil Environ., 2016, 62(5):237-242 | DOI: 10.17221/117/2016-PSE The purpose of the study was to establish quantitative and qualitative composition of soil-borne microorganisms in the cultivation of carrot. The experiment considered rye, white mustard, buckwheat and sunflower as cover crops and three systems of cultivation. The population of bacteria and fungi having an antagonistic effect towards selected fungi pathogenic to carrot was determined. The greatest total population of bacteria as well as Bacillus spp. and Pseudomonas spp. was observed in the soil when rye was the cover crop. The greatest quantity of fungi was found in the control, a slightly smaller amount - after using sunflower, buckwheat and white mustard. The system of tillage had no effect on the communities of the investigated microorganisms. Rye and white mustard had the most positive effect on the quantity of antagonistic Bacillus spp., Pseudomonas spp., Clonostachys spp., Myrothecium spp., Penicillium spp. and Trichoderma spp. Regardless of the tillage system, the smallest quantity of antagonistic microorganisms occurred in the conventional cultivation of carrot. |
Haematological and biochemical response of burbot (Lota lota L.) exposed to four different anaestheticsOriginal PaperP. Svačina, J. Příborský, M. Blecha, T. Policar, J. VelíšekCzech J. Anim. Sci., 2016, 61(9):414-420 | DOI: 10.17221/14/2016-CJAS The aim of this study was to compare the effect of four anaesthetics on haematological and biochemical blood profiles in burbot Lota lota L. Blood profiles of burbot were evaluated 10 min and 24 h after anaesthesia with tricaine methanesulfonate (MS 222) (100 mg/l), clove oil (33 mg/l), 2-phenoxyethanol (0.3 ml/l), Propiscin (1 ml/l) and compared to non-anaesthetized control. The tested anaesthetics had no effect on haematological profile of burbot. The exposure to clove oil, 2-phenoxyethanol, and Propiscin significantly (P < 0.01) influenced the level of ammonia and glucose. The level of lactate was significantly (P < 0.01) increased following anaesthesia with 2-phenoxyethanol and Propiscin. The levels of total protein, aspartate aminotransferase, and calcium were higher (P < 0.01) with clove oil, 2-phenoxyethanol, and Propiscin compared to control. The use of MS 222 showed the lowest effect on haematological and biochemical blood profile and is recommended as a suitable anaesthetic for burbot. |
Long-term evaluation of bicipital tenodesis with T-staple in three dogs: a case reportCase ReportS. Pinna, A. De Giorgi, G. SpinellaVet Med - Czech, 2016, 61(3):162-168 | DOI: 10.17221/8768-VETMED The purpose of this report is to describe the T-staple tenodesis of biceps brachii in three client-owned dogs and long-term ultrasonographic follow-ups. The orthopaedic examination revealed grade 2/4 (n = 2) and 3/4 (n = 1) lameness, moderate pain on passive movement and positivity to the tendon biceps test with a complete extension of the elbow during the flexion of the shoulder (Cases 1 and 2). Ultrasound examination was crucial for diagnosis of partial or complete rupture and tenosynovitis of biceps tendon. Surgical tenodesis was carried out with a metal T-staple. One-year ultrasound follow-up was performed, confirming the correct integration of the staple on the bicipital fibres and the absence of macroscopic tendon injury or degenerative disease. The results suggest that the metal T-staple could be a good alternative for bicipital tenodesis in dogs. |

Clubroot caused by Plasmodiophora brassicae Wor.: a review of emerging serious disease of oilseed rape in the Czech RepublicReviewVeronika Řičařová, Jan Kazda, Khushwant Singh, Pavel RyšánekPlant Protect. Sci., 2016, 52(2):71-86 | DOI: 10.17221/87/2015-PPS Winter oilseed rape is the second most frequently grown crop in the Czech Republic. Clubroot, caused by Plasmodiophora brassicae (Wor.), was previously a problem in production of vegetable. The disease has been spreading on winter rape (Brassica napus L.) over the past four years. Infected stands were reported throughout the country in autumn 2011. The pathogen is probably widely spread in the whole country, its incidence depends on suitable weather conditions. Every field with clubroot is considered as contaminated for many years. The amounts of inoculum and its distribution are not sufficient yet, but this is just the initial stage of colonisation. There is a similar situation resembling experiences from other countries (Canada, Germany) where clubroot has gradually expanded in the last 15 years. |
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. |
Monitoring of selected emissions of internal combustion engineOriginal PaperM. Králik, J. Jablonický, Z. Tkáč, Ľ. Hujo, D. Uhrinová, J. Kosiba, J. Tulik, R. ZáhorskáRes. Agr. Eng., 2016, 62(10):S66-S70 | DOI: 10.17221/72/2015-RAE The paper deals with the possibility of appropriate measurement and evaluation of emissions of nitrogen oxides. Development of exhaust systems which captures the solid particles emitted from engine, lost an objective assessment of the emission status of the diesel engine of agricultural tractor. Therefore, it is necessary to find a new method of measuring and quantifying the emission state of the diesel engine by measuring emissions, which should be economic and time-saving, but especially universal and sufficiently precise. The selected method should also provide sufficient information on such emissions that are subject to approval but they are not controlled during periodic checks. |
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. |
Presence of Arcobacter species in pet cats and dogs in the Czech RepublicOriginal PaperM. Pejchalova, S. Zabcikova, L. Silhova, D. Silha, I. Brozkova, M. HaslovaVet Med - Czech, 2016, 61(8):449-455 | DOI: 10.17221/273/2015-VETMED This study was conducted to evaluate the occurrence of the genus Arcobacter in cats and dogs in the Czech Republic. These animals may be carriers of the bacteria and potential sources of human infection. Oral smears were collected from animals using smear swabs and brushes. Based on previous studies, commercially available DNA kits were used for DNA isolation. Samples were analysed using polymerase chain reaction (PCR) and evaluated using gel electrophoresis. Overall, 178 oral smears were tested, of which 108 were from dogs and 70 were from cats. Out of all smears, five were positive, of which four samples were from dogs and one from a cat. In all five positive cases, PCR confirmed the presence of Arcobacter butzleri. In follow-up sampling, the presence of Arcobacter butzleri was demonstrated in two samples from a dog. |
The first contribution to the fauna of psocids (Insecta: Psocoptera) in forests in the Drahanská vrchovina Hills (Czech Republic)Original PaperD. MazáčJ. For. Sci., 2016, 62(5):211-222 | DOI: 10.17221/97/2015-JFS Taxocenosis of psocids (Psocoptera) was studied in the territory of the Drahanská vrchovina Hills in the Czech Republic. Representative research plots were selected in forest ecosystems with natural species composition and spatial structure (small-scale strictly protected areas) as well as in forest ecosystems with altered tree species composition and spatial structure. Research was conducted in three altitudinal vegetation zones (AVZ): in 2nd communities of Fagi-querceta s. lat. (beech-oak forests), 3rd Querci-fageta s. lat. (oak-beech forests) and 4th Fageta abietis (beech forests with fir). Research plots are situated at altitudes ranging between 275 and 540 m a.s.l. In the 2013 growing season, totally 3,474 imagoes and 2,532 nymphs of 32 psocid species were collected. Of those, 748 imagoes of 25 psocid species were collected in Fagi-querceta. The occurrence of Caecilius burmeisteri, Caecilius flavidus and Graphopsocus cruciatus was eudominant. 2,194 imagoes of 23 psocid species were found in Querci-fageta, eudominant were there Caecilius flavidus and Caecilius burmeisteri. 532 imagoes of 18 psocid species were found in Fageta abietis, eudominant were there: Caecilius flavidus, Peripsocus subfasciatus and Caecilius burmeisteri. In respect to the species composition, 3rd AVZ and 4th AVZ are similar to each other while 2nd AVZ is less similar. |
First record of Dendroctonus micans (Kugelann, 1794) on non-native spruces in Slovakia - short communicationShort CommunicationJozef VAKULA, Milan ZÚBRIK, Juraj GALKO, Andrej GUBKA, Andrej KUNCA, Ján PAVLÍK, Christo NIKOLOVPlant Protect. Sci., 2016, 52(4):277-282 | DOI: 10.17221/60/2016-PPS In 2015, we recorded the first attack of the great spruce bark beetle, Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae, Scolytinae) on non-native Picea orientalis (L.) and Picea pungens (Engelmann) in Slovakia. To our knowledge, the occurrence of D. micans on P. orientalis in Central Europe has not been described yet. We found that D. micans preferred P. orientalis over P. pungens and other coniferous trees in urban areas. In laboratory conditions, 352 adults of D. micans emerged and only 1 predator, Rhizophagus grandis (Gyllenhal) (Coleoptera: Monotomidae), was recorded. D. micans has a potential to become a serious pest of P. orientalis and P. pungens in urban, and in air-polluted areas. |
Influence of technology and ripening on textural and sensory properties of vacuum packaged ewe's cheeseFood Technology and Economy, Engineering and Physical PropertiesAlessandra Del Caro, Costantino Fadda, Anna Maria Sanguinetti, Maria Giovanna Carboni, Giuliano Pinna, Tormod Naes, Elena Menichelli, Antonio PigaCzech J. Food Sci., 2016, 34(5):456-462 | DOI: 10.17221/32/2016-CJFS The effect of curd cooking temperature (40 and 42°C), pressing, and ripening on textural and sensory properties of vacuum packaged semi-cooked ewe's milk cheese was studied. Chemical and microbiological analyses, colour, texture, and sensory characteristics were determined. Curd cooking temperature and pressing influenced aw, moisture and salt-in-moisture content. Texture parameters were partially modified by pressing. On the contrary, cooking temperature resulted mainly in changes of cheese colour. Storage time was the most important factor in changing cheese characteristics, including sensory characteristics, whereas an increase of bitter aftertaste was observed during storage, likely due to packaging in a plastic pouch. |
Response of soybean (Glycine max (L.) Merr.) to bacterial soil inoculants and foliar fertilizationOriginal PaperW. Jarecki, J. Buczek, D. Bobrecka-JamroPlant Soil Environ., 2016, 62(9):422-427 | DOI: 10.17221/292/2016-PSE Soybean yields can be considerably improved by inoculation with selected Bradyrhizobium japonicum strains and foliar fertilization. An exact field experiment was carried out in 2012-2014 at the Experimental Station of Cultivar Assessment in Przecław, Poland. The test plant was soybean cv. Aldana. The experimental factors were: bacterial inoculant Nitragina (Bradyrhizobium japonicum); foliar fertilization with Mikrokomplex; combined applications Nitragina + Mikrokomplex and the control treatment. Significant effect of Nitragina on an increase in the number of plants prior to harvest, plant height and the number of pods per plant was indicated. Fertilization with Mikrokomplex caused an increase in the number of pods per plant and thousand seed weight. Nitragina + Mikrokomplex increased the number of plants prior to harvest, plant height, the number of pods per plant and thousand seed weight. Seed yield was significantly higher in all the treatments compared to the control (2.31 t/ha). Higher soil plant analysis development values were found after the application of Nitragina + Mikrokomplex, and in the stage of pod development, also after foliar fertilization with Mikrokomplex. Application of Nitragina and Nitragina + Mikrokomplex resulted in an increase in leaf area index and mean tip angle and total protein in seeds. Fe content in seeds was the lowest in the control (69.2 mg/kg) and significantly higher in the other treatments (Nitragina, Nitragina + Mikrokomplex), and Mg content significantly increased after the application of Mikrokomplex and Nitragina + Mikrokomplex. |
Sensitivity analysis of key operating parameters of combine harvestersOriginal PaperM. Kavka, M. Mimra, F. KumhálaRes. Agr. Eng., 2016, 62(3):113-121 | DOI: 10.17221/48/2015-RAE The sensitivity analysis of key operating parameters on the average annual sub-profit in a group of three combine harvesters operating in companies providing agricultural services were analysed. Based on the results of the cost analysis, the following key operating parameters with the greatest influence on the costs were identified: the purchase price of the machine, the price of fuel, maintenance costs, personnel costs and annual performance. These parameters were used in the sensitivity analysis to investigate their effect on unit costs. Changing the above-mentioned parameters is calculated within ± 30% from their mean value. To perform a sensitivity analysis of the average annual sub-profit of combine harvesters, the unit price of mechanized work was additionally used. The results showed that greatest impact on both the average annual earnings of combines operation and on the changes in unit cost was those of the annual performance of the combine harvester, combine harvester purchase price and the cost of fuel. On the other hand, maintenance and personnel costs had a smaller influence concerning these changes of parameters. |
Response of organic nitrogen in Black Soil to long-term different fertilization and tillage practices in Northeast ChinaOriginal PaperLi YAN, Hui LI, Jinjing ZHANG, Zhidan ZHANG, Ping ZHU, Qiang GAO, Wenxi LUSoil & Water Res., 2016, 11(2):124-130 | DOI: 10.17221/32/2015-SWR A long-term (18 years) effect of different fertilization and tillage management practices- fallowing treatment (no fertilizer, no cultivation); CK (no fertilizer, cultivation); N (nitrogen fertilizer); NP (nitrogen and phosphorus fertilizer); NK (nitrogen and potassium fertilizer); PK (phosphorus and potassium fertilizer); NPK (nitrogen, phosphorus, and potassium fertilizer); M1NPK (chemical fertilizer plus manure); 1.5M1NPK (1.5 times M1NPK); NPKS (mineral fertilizer plus straw); Rot (3-year crop rotation of maize-maize-soybean with M1NPK), and M2NPK (2 times manure plus mineral fertilizer) - on the content of total nitrogen and organic forms of nitrogen and the nitrogen content in different particle-size fractions were studied in topsoil (0-20 cm) in Black Soil of NE China by using the methods of Bremner. The results showed that the combined application of organic and mineral fertilizers could significantly increase the contents and proportions of total nitrogen and organic nitrogen forms in soil. Comparing to CK treatment, the content of total nitrogen and hydrolyzable nitrogen increased in the fallow and organic materials treatments. Compared with M1NPK treatment, rotation was more beneficial to increasing organic nitrogen content, especially remarkably increasing amino acid nitrogen. The nitrogen response of sand, silt, and clay was most sensitive on manure; the effects of fallow and manure treatments on sand were notable, the nitrogen content in sand with NPKS increased by 40.86% compared with CK treatment. Our results imply that fallow/rotation managements, and manure/straw application can improve soil fertility. |
Determination of the diversity and antibiotic resistance profiles of Staphylococcus species from dogs with otitis externa and examination of mecA gene occurrenceOriginal PaperK. Metiner, A.F. Bagcigil, A. IlgazVet Med - Czech, 2015, 60(5):261-267 | DOI: 10.17221/8178-VETMED The aim of this study was to determine the distribution of Staphylococci from swab samples of dogs with otitis externa and to determine their antibiotic resistance profiles, particularly methicillin resistance. For this purpose 116 ear swab samples were collected from 100 dogs and examined for the presence of Staphylococcus species by conventional culture methods. Antibiotic susceptibility of the isolates was determined by the disk diffusion test and for methicillin resistance, by PCR. Forty Staphylococci were isolated from 37 (31.9%) of the 116 ear swabs. Among the 40 isolates, 30 of them were coagulase-positive Staphylococcus species (CPS), while 10 (25%) were coagulase-negative Staphylococcus spp. (CNS). S. pseudintermedius (n = 11), S. aureus (n = 8), other not determined Staphylococcus spp. (n = 7), S. chromogenes (n = 7), S. schleiferi coagulans (n = 3), S. hyicus (n = 1), S. hominis subsp. hominis (n = 1), S. simulans (n = 1), S. saprophyticus (n = 1) were isolated. Results of the antibiotic susceptibility tests have shown that 60% of the isolates were resistant to sulfamethoxazole/trimethoprim, 32.5% of them were resistant to erythromycin, 25% were resistant to clindamycin, and all isolates (100%) were sensitive to amoxicillin/clavulanic acid and cephazolin. The majority of isolates (97.5%) were sensitive to ciprofloxacin and gentamicin which are frequently used in otitis externa treatment. It was determined that only one (2.5%) (S. hominis subsp. hominis) of the 40 isolates was resistant to methicillin and carried the mecA gene. We found 77% of Staphylococcus spp. to be resistant to one or more antimicrobial drugs, and 25% of Staphylococcus species were found to be resistant to three or more antimicrobial classes. Thus, multidrug-resistance as detected in our study should always be taken into account and close attention should be given to the antimicrobial therapy protocols of pet animals. |
