A review on fish in vitro digestion studies
55-63Views:211(1) Background: In vitro experiments in fish have been developed to search for dietary substitutes of fish meal in aquafeeds by measuring the digestibility of various feedstuffs by simply simulating the conditions of the stomach or portions of the digestive tract. In vitro digestion studies involving mainly commercial fish species have been conducted to determine the digestibility of conventional and alternative ingredients in fish diets using diverse digestion models. However, there remains a significant knowledge gap, particularly regarding the enzyme functionality, digestion mechanisms in many fish species, and the factors influencing enzymatic activity. This review article is focused on the importance of the use of different enzyme sources in the in vitro digestion model to predict protein hydrolysis.;(2) Methods: For this review, a comprehensive analysis of articles was conducted to gain insights into diverse enzyme interactions and feed evaluation assessments, from the nutritional science and biotechnology sector.; (3) Results: A total of 36 peer-review papers, which include original, and review articles were selected.; (4) Conclusions: In vitro digestion studies offer a valuable tool for evaluating the digestibility of conventional and alternative feed ingredients, helping to identify sustainable dietary substitutes for fish meal while reducing dependence on live animal trials.

Study of animal welfare status and heat stress measures applied in dairy cow herds in Hungary
79-82Views:386The following material focuses on dairy production and climate related issues in Hungary. All the data was gathered during PhD
project: Study of animal welfare status in dairy cow herds in Hungary. Relations between animal welfare and climate changes expressed by
increase in temperature are described. Extremely hot weather creates hard conditions for milking cows when animal welfare is highly
compromised. From the preliminary results obtained one might formulate hypothesis that there are still areas on the farms where immediate
actions should be taken to give a relief to cows in hot seasons. There was found significant number of farms with too many animals per one
water trough, dirty water troughs, limited access to water troughs and hazardous surface for cows in critical places where many animals are
gathered. Calves with not sufficient amount of water in hot days and other parts of the year were reported. Silage exposure to the sun and
mouldy food in a silage clump was also found to be an important factor in monitoring impact of warm weather. Half of the farms letting
animals to spend time on the pasture or paddock did not provide shade for animals. Low conception rate of first insemination was predicted
to be influenced by heat stress, what is proved by lack of heat decreasing measures taken on the farms. -
The effect of different shading net on the Quantum Efficiency of PS II in chilli pepper cultivar ‘Star Flame’
21-23Views:582The study was undertaken to identify the effect of different shading net on the quantum efficiency of PS II on ‘Star Flame’ chilli pepper (Capsicum annuum) over a period of time cultivated under plastic house environment. ‘Star Flame’ pepper was grown under red shading net and samples without shading were used as control. Analysis of photosynthetic activity revealed a significant difference (p<0.05) between Fv/Fm values in control and red shading at the end of July (p = 0.031) after the first harvest. Chlorophyll fluorescence parameter Fv/Fm reflects the maximum quantum efficiency of photosystem II (PS II) used in the detection of early stress in plants.

Slight damage of the great green bush-cricket (Tettigonia viridissima) (Orthoptera: Tettigoniidae) in some Hungarian maize fields
65-70Views:478Characteristic cricket damage was observed in two maize fields in northern Hungary, at Máriabesnyő, a district of Gödöllő. The damage level of the two fields did not differ significantly and continual monitoring of field1 showed also a stable infestation level. T. viridissima nymphs and a female were found and observed as feeding on maize plants. The crickets must have disappeared after 18.07. because no more fresh damage was observed after this date. The chewing’s number about on one and two % of the examined plants amounted one and six a plant and their size was between one and eight cm2. This infestation was quite little and might have caused apparently no yield loss. Compared this damage of T. viridissima with former Hungarian experience, this was the usual negligible damage despite the explicit draught in July and August 2015. As regards the global warming, orthopteran damage may be more obvious in the future.

Pathogenic fungal pathogens and diseases: a mini review of effects on maize production
93-102Views:374Maize, the most important cereal globally in terms of nutrition and income, is highly susceptible to biotic stresses caused by various pathogens, including fungi, bacteria, viruses, nematodes, and parasitic plants. This review gives an account of the epidemiology, diversity, and effect of fungal diseases on maize, with a focus on common pathogens, namely Ustilago sp. and Fusarium sp. Additionally, the review explores the major contributors to the pathogen and disease development, namely: soil quality, temperature, and humidity. Clarity is made herein about the damages and effects on maize growth, including development, yield, and grain quality, with marked economic losses recorded annually. The increasing threat of climate change escalates the dangers, pointing out the urgency for sustainable control strategies of the diseases. Conventional methods of using chemicals have been rendered inadequate for maize fungal disease control, underscoring the need for applying biopesticides and natural products obtained from microorganisms as innovative, remediation strategies. Together with these innovations are biocontrol agents that provide better solutions for reducing the reliance on chemical formulations as well as strengthening a healthier agricultural environment. Finally, a comprehensive understanding of the interaction between maize pathogens and environmental determinants is vital for the development of more effective integrated pest management strategies to enhance maize productivity and subsequent food safety.

Economic impacts of applying EU animal protection regulations in hog breeding farms
76-80Views:323Hungary’s intention to join the EU makes it necessary to adopt, introduce and use the EU system of law. In Hungary, the legal control of animal welfare has improved (XXVIIIth law in 1998); however, most of our pig farms do not meet the EU animal welfare law requirements for some reason. We examined 9 pig farms in Hajdú-Bihar, Borsod-Abaúj-Zemplén and Heves counties. We chose those farms which use the combined breeding
technology most frequently used in Hungary. The most important part of the welfare directive is the definition of the minimum space per animal. We analysed the data in comparison with EU laws. On the basis of the analysis, it can be said that there is a narrow cross-section: the breeding of piglets. During the cost analysis, we analysed cost and highlighted the permanent cost. We studied how these costs would change if EU animal welfare laws were observed. We also examined the specific data per 1 sow and per 1 kilogram of slaughter pig. We compared the present data (1999) with those we get if EU animal welfare laws concerning minimal space per pig were now followed. It can be stated that after decreasing the sow live-stock in accordance with EU directives, the permanent cost would increase by 17,7% per sow. If the required space per sow were provided, the total cost per sow would increase by 1,9% from 421,1 thousand forints to 429 thousand forints, on average. This would mean a decrease of 7,9
thousand forints profit per sow. As with the decrease of the number of sows, the number of slaughter pigs also decreases. Total cost per 1 kg of slaughter pig would increase from 214,7 forints to 218,2 on average. -
Assessing the impact of salinity stress on some morpho-physiological traits of two chickpea genotypes under hydroponic conditions
47-53Views:356Evaluating the performance of crop species to salinity stress is considered an intricate task due to differences in performance, response and susceptibility at different phenological stages of chickpea crop. Assessment of the performance of chickpea genotypes in response to NaCl-induced salinity stress at the initial vegetative phase is of great importance to have a crystal idea about the threshold level of tolerance. An experiment was carried out under hydroponic conditions to evaluate the performance of two chickpea genotypes (ELMO and ORION), in response to different salinity levels (0, 25, 50 and 75 mM NaCl) as factorial arrangement under completely randomized design with three replications. The average of shoot and root dry matter weight was significantly higher for the ELMO genotype at the control treatment (1.143, 0.4133 g respectively), while it was significantly lower in the two genotypes ORION and ELMO at the highest salinity level (0.267 and 0.2700; 0.0433 and 0.0533 g respectively). The root to shoot ratio was significantly higher in both genotypes in the control and the lowest salt level (25 mM NaCl), without significant differences among them (47.98, 43.30, 37.10 and 36.25% respectively). The relative water content and stomatal conductance were significantly higher in the ORION genotype (88.01%; 335.40 mmol m-2 s-1) compared to ELMO (84.09%; 299.10 mmol m-2 s-1), and increasing salinity level caused a proportional decline in both traits, where they were significantly lower at the highest salt level (75Mm) (77.45%; 87.50 mmol m-2 s-1). Results indicate genotypic variability in response to NaCl-induced salinity stress under hydroponic conditions and the physiological traits are more expressive and reliable as selection criteria than morphological ones.

Evaluation of Lipizzaner mares’ fertility data in 10 Hungarian stud farms
23-26Views:207Despite numerous studies on the genetic background and performance traits of the Lipizzan breed, fertility characteristics of Hungarian Lipizzan mares have not been systematically examined. This study evaluates the reproductive performance of 220 Lipizzaner mares from 10 Hungarian stud farms, born during the period of 1981 to 2019, using breeding records from 1998 to 2022. The mares were grouped into 25 mare families and 24 birth cohorts. Data on successful pregnancies and foalings were analyzed with respect to age, family affiliation, and breeding year. Results show that mares aged 8–12 years had the highest fertility rates, while a gradual decline was observed after 15 years. Breeding activity increased markedly after 2011, peaking in 2022 with the highest number of matings and foals born. Fertility varied considerably among mare families: some achieved consistently high reproductive success, while others showed low or zero foaling rates despite repeated matings. Hungarian mare families generally produced better fertility results, whereas Fogaras families displayed greater heterogeneity. The study emphasizes the importance of monitoring reproductive efficiency in small mare families, as unfavorable fertility trends may jeopardize their long-term viability. These findings contribute to improving breeding strategies and ensuring the preservation of genetic diversity in the Hungarian Lipizzaner population.

Examination of different fungicides against Macrophomina phaseolina in laboratory conditions
65-69Views:411In Hungary, sunflower is the third most important arable crop, which has a lot of pathogenic fungi. One of these fungi is the Macrophomina phaseolina, which is a well-known fungus in all over the world, since this pathogen has more than 700 host plants. In Hungary, several host plants can be found as well. The M. phaseolina produces microsclerotia, which can survive in the soil and residues for almost 10 years. For now, there is no efficient treatment against this pathogen because of this fungus, since it is extremely resistant and cannot be destroyed easily. The only effective treatment against the fungus is genetic defence. In this study, three different fungicides were tested in vitro against the fungus. The Mirage (prochloraz) seemed to be the most effective fungicide as it completely arrested the hyphal growth. In contrast, the Amistar Xtra (azoxystrobin and ciprochonazol) has only a minor effect on the growth of M. phaseolina. Thirdly, the Retengo (pyrachlostrobin) arrested the hyhpal growth of the fungus with 71% at 100 ppm, in other words, the use of this fungicide seems promising.

Characterisation of basic water balance parameters of Debrecen
35-40Views:701This work aims to develop a hydrological modelling tool to help managers make the right decisions for Debrecen, in the face of water scarcity and the increase in agricultural and domestic needs over time. The methodology was based on the creation of a climatic database, at monthly time steps, from 2016 to 2019, and cartographic (land use, digital elevation model, and hydrological network). As a next step, the watershed was delimitated into sub-basins to determine the shape and the physiographic characteristics of sub-watersheds. Finally, a hydrological study was prepared by calculating the time of concentration to build a database of water resources in the study area. This water resource will be used as an input parameter for urban farming.

New occurence of woolly cupgrass (Eriochloa villosa [Thunb.] Kunth) in Hajdúság area, East-Hungary
51-54Views:501Because of the globalization and global warming the emergence of invasive weeds in Hungary are more common. The woolly cupgrass (Eriochloa villosa [Thunb.] Kunth) is published as an important invasive weed in Hungary. Woolly cupgrass is native in East Asia and it spreads into several parts of the World and causes difficulties in plant protection. It has been spreading extensively during the last few years,as the weed shows a very serious invasion potential.

Examination of Zn deficiency on some physiological parameters in case of maize and cucumber seedlings
5-9Views:226Zinc (Zn) is an essential micronutrient needed not only for people, but also crops. Almost half of the world’s cereal crops are deficient in
Zn, leading to poor crop yields. In fact, one-third (33%) of the world's population is at risk of Zn deficiency in rates, ranging from 4% to
73% depending on the given country. Zn deficiency in agricultural soils is also a major global problem affecting both crop yield and quality.
The Zn contents of soils in Hungary are medium or rather small. Generally, the rate of Zn deficiency is higher on sand, sandy loam or soil
types of large organic matter contents. High pH and calcium carbonate contents are the main reasons for the low availability of Zn for
plants (Karimian and Moafpouryan, 1999). It has been reported that the high-concentration application of phosphate fertilisers reduces Zn
availability (Khosgoftarmanesh et al., 2006). Areas with Zn deficiency are particularly extensive in Békés, Fejér and Tolna County in
Hungary, yet these areas feature topsoils of high organic matter contents. Usually, Zn is absorbed strongly in the upper part the soil, and it
has been observed that the uptakeable Zn contents of soil are lower than 1.4 mg kg-1.
Maize is one of the most important crops in Hungary, grown in the largest areas, and belongs to the most sensitive cultures to Zn
deficiency. Zn deficiency can causes serious damage in yield (as large as 80 %), especially in case of maize. On the other hand, Zn
deficiency can also cause serious reduction in the yields of dicots. One of the most important vegetables of canning industry is cucumber,
which is grown all over the world.
In this study, the effects of Zn deficiency have investigated on the growth of shoots and roots, relative and absolute chlorophyll contents,
fresh and dry matter accumulation, total root and shoot lengths, the leaf number and leaf area of test plants in laboratory. Experimental
plants used have been maize (Zea mays L. cv. Reseda sc.) and cucumber (Cucumis sativus L. cv. Delicatess). A monocot and dicot plant have
chosen a to investigate the effects of Zn deficiency, because they have different nutrient uptake mechanism.
It has been observed that the unfavourable effects of Zn deficiency have caused damage in some physiological parameters, and
significantly reduced the growth, chlorophyll contents of monocots and dicots alike. -
Optimal age of breeding gilts and its impact on lifetime performance
15-20Views:962Age at first breeding and lifetime reproductive performance was analyzed on 17,558 F1 Landrace x Yorkshire gilts from 9 piglet producing herds of Midwest, United States entered in herds between 1st Jan 2014 and 31st July 2016. At the time of data collection Dec 2018, 15% of the sows were still active in the herds hence excluded from the analysis. Individual gilt data included date of birth, age in days at first mating, piglet total born by parity, lifetime piglet total born and reason for culling. Quality data checks were done before analysis to eliminate all outlier values together with sows that had no entry information for any listed category. The total database of the sows was classified into 6 classes according to age at the first mating in days 170-190(n=754), 191-211(n=4683), 212-232(n=7123), 233-253(n=3385), 254-274(n=1002) and 275-369 (n=611). Piglet total born obtained from each sow during the lifetime production was significantly (P < 0.05) greater for gilts bred between 233-253 days of age at first mating. Gilts that were bred at <233 days appeared to have a higher risk of removal by farrowing productivity as compared to the other groups. However, the results show that the risk of being culled due to health problems and conformation issues increases as the age at first mating is delayed. Overall reproductive failure appears to be the most economical culling reason across all age groups. There is a need to evaluate the best management decisions for gilt initiation in a herd to maximize her lifetime performance. The results indicate that gilts mated for the first time at the right age, 233–253 days, are more productive, both in lifetime total born and have a minimal risk of culling due to farrowing productivity.

Changes in the Hungarian law and in the classification system regarding to ’people living with disabilities’ between 2008 and 2013
43-55Views:260Nowadays employment is a hot topic in Hungary. The rate of inactive people on the labour market is very high. Many kinds of supplies are provided by the State for example for the group “people living with disabilities”. It is very difficult to provide job for these people after their rehabilitation. Statistical figures show, that the highest ratio of “people living with disabilities” can be found in the North Great Plain Region of Hungary (30 per cent of the total number of “people living with disabilities”).
The employment of these people means extra costs for enterprises. At the same time the complete accessibility of workplaces is still not realized in many cases in Hungary yet. Currently only a few enterprises are specialized to employ people living with disabilities in the North Great Plain Region. Unfortunately most of the enterprises don’t want to employ them. New workplaces for these people should be created by the utilisation of European Union and national available sources in order to integrate them into the job’s world in long run. I represent the changes in the law and in the classification system in this area.

Environmental Indicators – Agri-Environmental Indicators
248-255Views:189close relation. This means that policies related to the economy and the environment cannot be handled without each other. The United Nations Conference (Stockholm, 1972) was the first global conference to signal that environment concerns have increasingly become subject of mainstream socio-economic policies. The process started in the Seventies, laying emphasis on environment protection, plays an important role in the policy of international agencies. The use of environmental indicators is essential for monitoring the effects of environmental measures. The best way of evaluating sustainability if the results can be compared on a global level. International efforts are being made by the United Nations (UN), the Organisation for Economic Co-operation and Development (OECD), the Statistical Office of the European Commission (Eurostat) and other international agencies to develop a framework for environment statistics. This study deals with these frameworks, paying attention to agri-environment indicators. Hungary became a member of the UN in 1955, of the OECD in 1996, and will become a member of the European Union in 2004. The first summary in connection with environmental indicators of Hungary, taking the OECD Pressure – State – Response framework as a basis, was published in 1994. As a result, comparability of environmental indicators for Hungary with those used international are given.

The correlation of foreign language proficiency, employment and regional competitiveness in the North Great Plain Region of Hungary
74-82Views:152Employment is one of the basic factors when evaluating a region’s competitiveness. Boosting employment figures will also increase individual income. However, the creation of jobs alone will not solve the problems of unemployment, as labour force with skills matched to labour market demands should also be available. Continuous development of the labour force, adjusted to recent needs in the labour market, can contribute to a region’s competitiveness. Mismatches between education and labour market requirements would be too expensive, especially for backward regions like the North Great Plain Region of Hungary. Foreign language education should also be adapted to the changing economy when selecting target languages and language skills. A workforce equipped with contemporary and needed second language skills can be an element in making a region attractive for investors. Although current trends show signs of improvement, Hungary and especially the North Great Plain Region still does not have much to offer in this respect. The paper examines the reasons for the low level of second language acquisition among Hungarians and the population of the North Great Plain Region and explores the ways foreign language knowledge could promote economic development.

Occurrence and damage of the alfalfa root longhorn beetle (Plagionotus floralis Pallas, 1773) in old alfalfa stands in Hungary
82-88Views:342The alfalfa root longhorn beetle is a pest of small importance in old alfalfa stands. It is rarely cited in the international, national literature, or even mentioned in specialized manuels. Plagionotus floralis is common in Hungary but its population density is low. It is a polyphagous species but it has importance - regarding the references – only in alfalfa. This paper analyses data gained in old alfalfa fields at two different regions of the country (Máriabesnyő, Debrecen). Damage of P. floralis was 56% in the roots of an 8-year-old stand in Máriabesnyő. Lenghts of tunnels were between 3 and 22 cm. In spite of the tunnels the alfalfa plants were viable. There was no root longhorn beetle in the 15-year-old Debrecen stand, however it has been found former in the region. The reason for the important density of P. floralis in Máriabesnyő could be the considerable diversity and covering of flowering weeds around the field. Adults of P. floralis feed on flower pollen and nectar. As to the Debrecen area,weeds were cut regularly, so the edge vegetation was poor. Present conditions (no pest control on alfalfa fields, overuse of old and failing alfalfa stands, many untrained growers) favour the reproduction and possible damage of alfalfa root longhorn beetle.

Results of weed surveys in greening plants
53-57Views:355Greening crops play an essential role in Hungary's agriculture. Weeds can also cause many problems during the development of greening plants. Our research aimed to evaluate the weed control properties of greening crops sown with different germination rates. Analysis of the effect of crop rotations on weed density. Comparison of weed growth in control, fertilised and greened areas. In October of 2021, a weed survey was carried out in lupin (Lupinus albus L.), common vetch (Vicia sativa L.), oil radish (Raphanus sativus var. oleiferus L.) and buckwheat (Fagopyrum eculentum Moench). During the weed survey, we determined the different weed species and their abundance. In terms of seed rates, the higher seed rates for lupin, oil radish, and buckwheat may be worth choosing for weed suppression. Plots in rotation III had the lowest weed incidence of all greening crops. The probable reason for this finding is that there was no prior greening in rotation III. For greening, the choice of buckwheat and oil radish will result in higher weed pressure. The most important weeds were the cereals sown before the greening crop. Fertilised plots had minimally fewer weeds than control plots. Research results show the difficulties of weed control in herbicide-free greening crops.

Production and disposition of purebred Jersey populations
89-96Views:444In Hungary crossbreeding wit Jersey has been in practice since 2004. Uniquely in the Hungarian history of the Jersey breed two times fifty head pregnant heifers were imported in 2006. The aim of our study is to present through the description of the production and the type traits of the population the inherent possibilities of Jersey. The breed is presented by the figures of the rolling lactations, 305 day milk production, correlations between the traits and by the results of the evaluation of type traits. Analyses of the data were done by using independent samples t-test.
Based on data of 87 cows the average number of days in milk is 308 and 48 cows has finished lactation. During the rolling lactation they produced 5050 kg milk with 5.34% fat and 3.8% protein content.
The first lactation Jersey cows’ production when corrected to 305 days was 5089 kg milk with 5.35% fat and 3.81% protein. Between the herds there was significant difference in milk kg, amount of fat produced, protein content and amount of protein produced. On the two farms distribution of cows belonging to different production levels is very different. The biggest difference is when categorized by the amount of milk produced.
Correlation between the milk kg and fat kg is the greatest (r=0.950). Similar values were obtained for the correlation between fat and protein kg (r=0.919) and for the milk kg and fat kg (r=0,898).
Disposition of the Jersey cows is very well balanced. Their stature, strength, body depth, dairy form, rump angle and pin width is favorable, the average scores are between 4.5 and 6.5. The leg of the cows is a bit sickly, and is hocking in a little with medium-low angled hoof. Average values of all traits describing the udder are between 4 and 5. Cows belonging to the two herds differ by disposition. Significant difference exists in the following traits: body depth, dairy form, pin width, rear leg - side view, rear leg, rear view, foot angle, fore udder attachment, teat length. The
Jersey population imported to Hungary has a final score of 78 points which equals with the “good” qualification. -
Examination of different grain hardness varieties of the grinding technology properties of wheat
423-435Views:348In the mill industry, the purpose of the grinding technology is to separate wheat endospermium and shell and to recover grists. The most important and the highest energy requirement operation is shredding. Flour quantity and quality produced from wheat depends on the variety of wheat that will be shredded, the type of grinding equipment and the condition used before the grinding. For this reason, during my experiments, I ground two grain structured varieties of wheat in laboratory conditions using a disk grinder, stone grinder and roll grinder in air-dry and conditioned states. We measured the equipment’s performance and the produced grist’s particle size distribution, followed by the calculation of the energy requirements of the grinders. In the grinding experiments we compared the ash contents of the different particle sized grist’s fractions to map the wheat’s particular properties.

An overview of swine production and marketing in Africa - Mini review
121-129Views:678Pigs are the oldest domesticated animals, though their ancestry is still uncertain because of a lack of archaeological and genetic evidence. Pigs serve a vital role in reducing the demand for livestock and livestock products in most parts of the world. Especially in the African continent, pigs serve as mobile cash implying how easily they can be converted into cash to sort pressing family needs. Pig production in Africa is different from advanced systems of production in temperate countries, however, it has similarities with most of the tropical low and middle-income nations. Pig production in Africa requires attention to enable it to contribute effectively to the growing African population. However, it has been orchestrated with a myriad of challenges including market access. This mini-review is designed in a manner to provide an overview of pig production contribution to livelihoods in Africa and associated challenges with possible appropriate solutions.

Connections between land usage, property structure and agricultural enterprises in Hungary
31-34Views:185The last decade of Hungarian agriculture was marked and changes which affected all parts of agricultural production. This process resulted in a new ownership and organisation structure. The paper presents the effects of the changes in ownership on land use and the various enterprise forms and intends to outline the main tendencies. In general, it can be stated that the role of agriculture in GDP production and employment is decreasing in Hungary, but according to concurrent opinions of experts, agriculture still has and will have a major role in income production and the ease of social tensions in rural areas in the future as well. Hungary’s accession to the European Union provides new chances and new prospects for Hungarian agriculture and rural areas. Hungarian agriculture became a part of the internal market which includes about 450 million people. The safety of marketing became stronger, the rate of financial support is increasing and the income of growers will increase in the future. This process implies more obligations and the keeping of strict regulations. Competition inside the internal market is intensifying, competitiveness will be more important while the chances of development and investment of the growers and the feasibility of more effective land use are increasing. After the accession, integration into the directives formulated in the CAP and the packages of measures accepted in it is framework have growing importance.
These directives encourage farm-reallocation, namely the rational estate concentration. In general, it can be stated that rational estate concentration, and more effective land use as a consequence, will increase the efficiency of agricultural production. -
Characterization of Hungarian touristical turnover 2006-2009 – focus on health tourism
47-50Views:240Tourism is one of the biggest and mostly increasing branch all over the world. Since it is getting more and more significant in Hungary as well in this article I analyze the turnover of Hungarian tourism on the basis of guest nights spent on commercial lodgings. I examine its changes in time and its territorial spreading. Finally I explore the health touristic volume, because it is one of the most important touristic product of Hungary and the North Plain Region and the infrastructure based upon preserves unique opportunities both for health and wellness tourism.

Interpretation of rurality and the situation of land use in Hungary
79-85Views:509The summarizing data collection of our study has been carried out in the scope of the FP7-REGPOT-2010-1 ’UD_AGR_REPO’ project as a part of the cooperation with the University of Lincoln. The University of Lincoln is an important partner of the project, the knowledge transfer activities that have been carried jointly with them are multilateral. One of the most important cooperation areas is the analysis of rural areas, rurality itself, determination of breakout points, exploration of alternative income sources, diversification possibilities. Some part of the work of the University of Lincoln on the field of rural development is based on the assessment and documentation global similarities and differences of rural areas. Present study also contributes to that work, it has been prepared on the request of the University of Lincoln with the aim of providing insight into the special political and economic changes/processes that took place in Hungary, and through them into the structure and operation of the unique Hungarian rural areas.
The study first positions the definition of rurality and rural areas into context on the basis of official EU and Hungarian legal classification. Then it covers the important agricultural nature of Hungary, which significantly determines the possibilities and properties of Hungarian rural areas. The further description of rural areas is completed by some historical summary, the introduction of ownership changes, detailed description of employment and income conditions and finally by the listing of breakout points of rural areas as a conclusion.

Lack of polymorphism of the agouti signaling protein (ASIP) gene among four different brown hare (Lepus europaeus Pallas 1778) populations
81-85Views:417The brown hare (Lepus europaeus Pallas 1778) is a common palearctic and a popular game species therefore it has been an obvious subject for population genetic studies since the second part of the 20th century. Among the several mitochondrial DNA studies some have been carried out concerning nuclear genes as well. The agouti signaling protein gene (ASIP) is involved in regulating the synthesis of eumelanin and pheomelanin in melanocytes of mammals. Though many studies focused on it in relation with several mammalian species, minimal information is available on this topic concerning the brown hare.
Here we present a short communication concerning the agouti signaling protein (ASIP) gene in four different country’s L. europaeus populations, namely Lithuania, Hungary, Serbia and Georgia. N=45 tissue samples have been investigated from overall 17 sampling sites of the different countries. There has not been found any polymorphism among the sequences. In an alignment with other Leporid species’ partial ASIP sequences downloaded from ENA we have found that based on a 178 base pairs long DNA sequence the haplotype of our samples contains three other Lepus species as well. This is concordant with the findings of a previous study focusing predominantly on the European rabbit (Orycto lagus cuniculus Linnaeus 1758) and the several mutations of its ASIP gene.
