Landscape use of protected areas in the Hódmezővásárhely micro-region
179-193Views:78One of the biggest questions of developing rural areas is that people and organisations living and making their activity there how and in what measure utilize the local or obtainable external
resources. The concept of the landscape expresses the direct connection of the natural resources with the socio-economic processes. This is a two-way connection, (1) on the one hand the single landscapes provide the unique combination of natural conditions for the socio-economic utilisation which is different from other landscapes, (2) on the other hand as the result of the interaction of natural spheres together with the social and economic spheres the landscapes change in a different manner and in a different measure. The landscape as a territorial unit and as a resource is inseparable from the natural resources, and the nature
conservation plays an increasingly important role in the use of the landscape and landscape management, which is an essential task not only in protected areas, but everywhere. The natural resources, the landscape, the nature conservation and the landscape use are related tightly, in which the so-called ecological/biological resources and their sustainable use have a
significant role. -
The impact of population management on urban and rural Hooded Crow populations
119-123Views:76Hooded Crow (Corvus cornix), originally native to agricultural areas, has become widespread in urban areas in recent decades. However, this process has negative consequences on urban animals and humans. Due to these problems, the control of urban crow populations is needed. Crows also cause significant damage to wildlife management, and are constantly being controlled in rural areas as well. In this study, we compare rural and urban populations to find out whether hunting activities have a population reduction effect. In the rural population, the reduction is carried out by weapons and traps, while the urban crows are controlled using traps only. In both sample areas, crow nests were surveyed during the nesting period. 29 active nests were monitored in the rural area in 2021, and 39 in 2022. In the urban area, 44 nests were recorded in 2021 and 35 nests in 2022. In 2021, 30 individuals were removed in the rural area, and 84 in 2022. In the urban area, 223 individuals were removed in 2021 and 144 in 2022. Results show that the number of crows removed follows the number of active nests, so that the reduction of a given year is likely to have an effect on the following year's nesting population. Because traps mostly capture juvenile birds, reducing the breeding population in the city can only be achieved in the long-term. Considering this, it is likely that increased attention to population control can effectively maintain crow populations and reduce the problems they cause.

Evaluation of population parameters and biometric data of an Eurasian Collared Dove (Streptopelia decaocto Friv.) population in the Great Plain of Hungary
89-92Views:316The Eurasian Collared Dove shows different patterns in density all over Hungary. In some cases, the population has decreased to a lower level, but there are habitats where the population remained stable. Several factors were taken into consideration during the evaluation of this phenomenon. These publications state that the increased urbanization of corvids, the lack of food sources, and the changes in nesting sites caused the decrease in numbers. During our research, we intend to contrast the differences in population structure of Collared Doves that differ from each other in the density of predators presented at nesting sites. As a first step, in this paper, numerous samples (n=118) were taken from a population that is less influenced by corvid species’ nest predation. Our prediction was that the population parameters remained at the level of 1980’s, in which the population of Eurasian Collared Dove has reached its maximum, according to further publications.
During the evaluation process, our data were collected from hunting bags near Nyíregyháza. Results were compared with former publications. We stated that the population structure, such as age and gender distribution remained stable in the evaluated population. In addition, morphometric factors of the collected individuals were also measured, such as weight, wing length, 3rd primary feather, and tail length, which were compared with former surveys. During statistical tests no significant difference was revealed among population parameters, but there were significant differences between most of the morphometric data, (p>0.05).

Az elmúlt tíz év változásainak vezetői értékelése különböző szervezeti formában működő vállalatoknál
82-86Views:99revolutions and changes. Effects of these changes can be sensible at all parts of agricultural production. It results in new ownership and organisation structure. Agriculture has to suit to the new circumstances of changed firm-size and structure. These kinds of changes essentially define conditions of agricultural production in the future, and they have an affect on husbandry of enterprises.
To be succeed in managing changes, we have to know the reasons of these alterations and nature of them. It is very important to get to know the advantages and disadvantages of the typical change-management methods and its typology. These methods are more elaborated and widespread at industrial enterprises. It is necessary to get to know the nature, characteristics and reasons of changes, and we should work out ways agricultural companies, taking notice of their speciality.
The methods and means of examinations
We aimed to point out what kind of changing processions were typified the activity of agricultural ventures. What are the speciality, strains, the arousing and obstructive factors of nowadays changes. We made questionnaire and sent them to numerous enterprises.
Most of the answers show that leaders are „floating with flow” and most part of their power is used to fight back actually challenges. Generally consciousness is missing, so they are not govern the events still more they are passive objects of occurrence.
Naturally, the given answers show, that the most important changes of past are changing of markets, importance of quality production and changes in the structure of enterprises. And – especially at companies, which deal with plant growing –, modifying of structure because of compensation. -
Possibilities of biodiversity conservation in agricultural fields
39-45Views:122The biodiversity loss is one of the biggest environmental problems in the world. The objective of this paper is to present some nature conservation practices on agricultural land. Farmlands play a significant role to preserve biodiversity because some highly protected species can only find their needs on agricultural land. The Biodiversity Strategy of the European Union (2010-2020) creates new directives to reduce biodiversity loss, preserve and improve diversity, especially on agricultural land. Furthermore the importance of this subject is that the share of farmland in Hungary is much higher (57%) than in the EU-27 on average (42%). The loss of agricultural land and the increase of land abandonment cause intensification of agricultural production leading to the loss of biodiversity.

Mitochondrial DNA-based diversity study of Hungarian brown hares (Lepus europaeus Pallas 1778)
23-29Views:131The brown hare being an important game species which is widespread across the European continent has been in focus of many population genetic studies. However only a few comprising researches can be found on the diversity of Central-European populations.
The aim of our large scale long term ongoing study is to fill this gap of information on the species by describing the genetic history and structure of the brown hare populations of the area using both mitochondrial DNA markers and genomic skin and hair colour regulating genes.
This article gives forth a part of our results concerning the mitochondrial DNA diversity of Hungarian brown hares based on amplification of a 512 bp long D-loop sequence. N=39 tissue or hair samples have been collected from 15 sampling sites on the Hungarian Great Plain. We have described a high level of haplotype diversity (Hd=0.879±0.044) based on a 410 bp alignment of our sequences. We have found 17 haplotypes within our sample set with the nucleotid diversity of π=0.01167±0.0022. Our ongoing research shows high genetic diversity for the brown hare in the studied region and a second alignment with 156 sequences downloaded from GenBank indicates a geographic pattern of haplotypes among the studied populations though these results need confirmation by our further analyses.

Marginalisation and Multifunctional Land Use in Hungary
50-61Views:75Our study prepared as a brief version of National Report in the frame of EUROLAN Programme. We deal with the interpretation of some definitions (marginalisation of land use, multifunctionality of land use, marginalisation of agriculture, multifunctionality of agriculture), with sorting and reviewing indicators of marginalisation and finally with the analysis of functions of land use. We suggested a dynamic and a static approach of marginalisation. We can explore the dynamic process by time series and the static (regional) one by cross-section analyses.
It is very hard to explain the perspective of the future of marginalisation of land and of agriculture in Hungary. The process of marginalisation seems faster in the agriculture in the coming years, but it depends on the utilisation of new possibilities given by the EU financial resources and by the Common Market. At this moment agriculture seems one of the big losers of the accession.
In the long term we should face considerable challenges in the land use. It is necessary to take into account that there is a supply market of foods and traditional fibre production world-wide. There are limited possibilities to produce and to market for example biodiesel (fuel), bioethanol, or maybe biogas. Thus the environment and landscape preservation becomes more and more real land use alternatives.
The environmental interpretation of the multifunctionality of land use: activities (functions) of environmental preservation and nature conservation in a certain area, which aim to preserve natural resources by the existing socio-economic conditions.
Preservation of rural landscapes is the task mainly for land-users, who can be commanded by legal means and can be encouraged by economic measures to carry out the above activity. In the recent past measures of „command and control” type regulation were predominant, however nowadays, especially in the developed countries, the role of economic incentives increases.
As a conclusion of our analysis we can state that as long as the main land-dependent activities (agriculture, forestry, housing, tourism, local mining) cease to be viable under an existing socio-economic structure, then it is hardly possible to sustain the rural landscape on an appropriate level by non-commodity products (such as environment preservation, cultural heritage, nature conservation, employment etc.).
1 The study was prepared in the frame of EUROLAN (EU-5 Framework Project), QLK5-CT-2002-02346, as a compiled version of the Hungarian National Report, The national project co-ordinator: Prof. Dr. Gabor Szabo.
A part of places with high ecological values coincides with the areas with unfavourable agricultural endowments and underdeveloped micro-regions. We think so that the marginalisation preserves the non-environmental-sound activities and hinders the development of multifunctional agriculture and this process can change only by joint utilisation of endogenous and exogenous resources and methods. Thus the successful programmes for agri-environmental protection and multifunctional land use can serve the moderation of negative effects of marginalisation or maybe the marginalisation process itself. -
Survival analysis of sow longevity and lifetime reproductive performance – Review
75-80Views:254Sow longevity plays an important role in economically efficient piglet production. Improving sow longevity results increase in the productivity and profitability of a sow herd. Longevity is a complex trait with many factors that can contribute to a sow having a long and productive life. Not only the sow’s genetics, but also nutrition, environment and the management policies are important. In addition, the removal of non-productive sows along with the introduction of replacement gilts is an essential part of maintaining herd productivity at a constantly high level. The objective of this paper was to summarize the current knowledge about the sow longevity and lifetime performance values, as well as, discusses the survival analysis methods for sow longevity traits. This method can estimate the hazard rate indicating proportional risk of sows being culled at any given time, in addition, it is able to investigate the effects of different factors on longevity. Identifying factors that influence the longevity could assist many commercial pig producers in becoming more efficient.

HPLC-MS analysis of the active ingredients of chamomile (Matricaria chamomilla) bee feeding syrup
61-65Views:240Apiarists let prepare by bee honey products containing medicinal drugs. Our aim was to prove that the active ingredients originated from the herbs are also present in the bee products. This publication focuses only to the chamomile (Matricaria chamomilla) containing feeding syrup and the difference between the various syrup phases. To fulfil this task, we developed a method analysing the non-volatile components of the syrup using the flowers of chamomile. The method involves a filtration followed by HPLC-MS analysis. The analyses and the data evaluations proved that the non-volatile components of the herb were transferred to syrup. As the characteristic components of certain herbs could be identified also in the syrup, it is obvious that the components responsible for the medicinal effects are also transferred.

Comparision of growth of mature all-female and mixed-sex Common carp (Cyprinus carpio L.) stocks in RAS
65-68Views:441The common carp (Cyprinus carpio L.) is the most important fish species in Hungary, it is more than 70% of the total Hungarian fish production. The common carp production is important not only just in Hungary but in Middle-East Europe, as well as Southeast Asia. Majority of the production comes from fishpond culture. If the production sector wants to meet the increasing customer demands, there is need to intensify research on the intensive fish production opportunities for example all-female common carp technologies. The all-female technology is one of a genom-manipulation technology. Its production showed better growth rate than mixed-sex population in pond culture. Our experiment combined the recirculation aquaculture system (RAS) and the all-female common carp stocks intensification technologies. The reason for the experiment, is that there are no result about the growth of all-female common carp growth in RAS.
The experiment used the „Tatai grey scale type” common carp stocks. We propagated two all-female stocks (T2 and T3) and a control group (TK). Due to technological characteristics of RAS, the water quality parameters were the same for all treatments and corresponded to the technological tolerance of common carp.
The experimental period was from July 10, 2019 – November 20, 2019. Result of growth performance showed that the growth of mixed-sex stock was significantly higher than all-female stocks; (Control=3692.0±590.5g, T2=3438.8±415.4g, T3=3294.1±659.1g). Feed conversation ratio (Control=1.3±0.1 T2=1.5±0.2 T3=1.6±0.5) and SGR% (Control=0.8±0.0 T2=0.7±0.1 T3=0.7±0.1) were similar.
By the results it can be said the all-female common carp technology has neither advantages nor disadvantages compared to the mixed-sex stock. The all-female technology can be beneficial if the consumers need female common carps. It is worth continuing the experiment and examine how the stocks will perform above 3kg body weight.

Environmental Conditions of the Berettyóújfalu Sub-Region
403-413Views:64The purpose of this paper is to introduce the environmental conditions of the Berettyóújfalu sub-region, which is geographically located in Hajdú-Bihar County. I specifically target the regions’ relief, soil and hydrogeological conditions, climate, flora and fauna, natural value and present nature conservation activities.
On the basis of my investigation of these points, I can state that although this sub-region has unfavorable soil conditions, polluted surface and subsurface waters, it is rich in thermal waters, nature reservations and wildlife. It’s disadvantageous characteristics can or should be amended, while the advantageous ones should be utilized by considering the principles of sustainability. At the end of this paper, I will make recommendations in connection with the latter point. -
Effect of genotype on the hematological parameter of TETRA-SL and Hungarian Partridge coloured chickens at young age
99-104Views:184Indigenous chickens are well known for their dual-purpose function and palatable meat. However, the information on their hematology parameters is lacking and hence hampering the poultry industry production of local breeds. The main objective of this study was to examine the hematological parameters of Hungarian Partridge Coloured hen (HPC) and TETRA-SL (TSL) genotype and determine the hematological reference interval values. This trial was part of the larger experiment where a total of 200 chicks (HPC + TSL) were reared. For this trial the blood samples were obtained from brachial wing veins of 8 chicks of each genotype for blood hematological analysis. The results indicated that some of the hematological parameters such as red blood cells-RBC, white blood cells-WBC, hemoglobin-Hb, hematocrit-Ht, platelets-Plt, lymphocytes-LYM, and granulocytes-GRAN were significantly affected by the genotypes (p < 0.05). The genotype did not affect the mean corpuscular volume-MCV, mean corpuscular hemoglobin-MCH, mean corpuscular hemoglobin concentration-MCHC, and GRAN (p > 0.05). The hematological reference interval values were slightly higher in the TSL genotype compared to HPC chicks. It is concluded that genotype has a significant effect on the hematological parameters. The results from this trial will be help and design the baseline reference values for the HPC genotype which will be useful in assessing the health status of these indigenous chickens.

Insect base-protein: A new opportunity in animal nutrition
129-138Views:459The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protein can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.
This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.
The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.
However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

The father of the term ‘biotechnology’ was Hungarian: The forgotten works of Károly Ereky
107-110Views:294In the Nature, Robert Bud gave an account of the fact that the generator of the concept "biotechnology" was the Hungarian Karl Ereky who, in his book published in Berlin in 1919 entitled "Biotechnologie der Fleisch-, Fett- und Milcherzeugung im landwirtschaftlichen Grossbetriebe" ("Biotechnology of Meat, Fat and Milk Production in a Large-Scale Agricultural Farm"), disclosed his observations and new views in that regard. Later on, Ereky's two essays, published in German language again, and other contemporary German sources have been processed which have confirmed the assumption whereas – in scientific terms – the further first applications of the expression "biotechnology" can be attributed to Ereky's works. Recently, we have explored and found biographical sources and documents which had been published by Ereky, which, however, have already been forgotten, by dint of which the story of origin of the first concept "biotechnology" can as well be clarified in a factual manner.

The Effect of Changes in Forest Area on the Transcarpathian Tisza River Basin
181-185Views:66Forests are unique global factors which ensure life for almost every living being on Earth. They play a major role in controlling water flows, preventing erosion and controlling the oxygen content of Earth’s atmosphere. By the end of the XXth century, it was realized that forests help to nature maintain and are vital parts of our natural environment. By the time societies realized this fact, economic and environmental effects had amplified which endanger forests. Due to their good water control and water protection abilities, and their function in climate control, mountain forests can provide a suitable environment for themselves, for their successful growth.
Forests play a major role in soil protection, especially in mountain areas where they prevent soil erosion. By converting surface waters into subsurface waters, forests help with the accumulation of subsurface waters, which are the sources of springs, rivers and streams. In the summer, they protect the soil from drying out by creating a special microclimate. They positively affect the climate of surrounding territories. -
Different ideas on the pathogenesis and treatment of swine edema-disease
45-48Views:150Although literature data associate the reason of swine edema-disease with certain serotypes of Escherichia coli bacteria, the authors assume that the primary cause of edema is more different. Susceptible agents and factors, mostly of feed compound are involved. During the digestion of some feed-origin protein opiate-like metabolites, exorphins arise, simultaneously arrest the release of acetylcholine. Consequences of acetylcholine shortage are spasm of sphincters (mostly pylorus), intestine-dilatation, contraction of bladder-sphincter, and urine retention. The endorphins and exorphins intensify the insulin release from the pancreas, hypoglycemia evolves, which is associated with loss of balance. According to the authors in edema-disease piglet dies because of hypoglycemia.

Daily soil carbon dioxide flux under different tillage conditions
141-144Views:158Over the last few years, warming of the atmospheric layer near Earth's surface is increasingly experienced and researchers have also established that concentration of numerous greenhouse gases have risen over the past two centuries value. Change is basically a legitimate process - considering atmospheric concentration as well - but the change experienced during the past centuries could not have become this critical without the contribution of human activity. Due to the nature of the greenhouse effect, the result of a very fragile, complex process is experienced currently on Earth, which can be significantly unbalanced even by a slight change. Carbon dioxide emitted from the soil is involved in the global cycle and has an impact on the greenhouse effect. The rise in soil respiration may result in the further intensification of warming. In the scope of the present study, it was examined how carbon dioxide emissions of the soil evolve over a day. The results have been established based on the comparison of the effects of different parts of the day, tillage methods and irrigation.

Significance of biogas production in Hungary
127-129Views:111It is known that the quantity of fossil energy sources are rapidly reducing, therefore it is necessary to determine a new direction which has to point directly to renewable energy sources. Increasingly comes into view the agriculture’s energy producing nature next to it’s traditional food producing one. The enviromental protection is connected to the energy production by the ultilization of biomass for energy purposes, within the biogas production has an emphasized importance. Quasi every organic material can be used in biogas production, such as: food processing by-products, manure, sewage sludge, hoousehold waste.

Yield and sward composition responses of a native grassland to compost application
35-38Views:170A major part of the animal products are based on the grasslands, due to the fact that the grassland ecosystems can be found all over the globe. In places where economical and successful crop production cannot be realized, the grassland based animal husbandry can be an efficient way of food production. In addition these ecosystems have an important role in carbon sequestration, and with their rich flora – and the fauna connected to it – in conservation of biodiversity. The protection of nature, and the sustainable agriculture is getting more and more attention in the European Union, but looking at the consumers’ needs, the production of healthy food cannot be neglected either. Because of these facts, the effects of two specific composts - which are officially authorized in organic farming, in Agri-environment Schemes and Natura 2000 programs – on grass yields and sward compositions were investigated in a field trial. The investigation took place in Hungary, on a natural grassland based on solonetz soil. The first type of compost was a natural one (N) without any additional material and the other one was enriched in phosphorus (E). Both was produced by the research institute, made of sheep manure. Three rates of compost (10 t ha-1, 20 t ha-1,30 t ha-1) were tested on 3 m×10 m experimental plots. Every treatments had four replications and both type of compost had four-four control plots too, this way 32 experimental plots were included in the investigations. The yield of the pasture was harvested two-times (in May and in September) and before cutting the plots measurements on botanical compositions were made. Samples for laboratory analysis were also taken. Dry matter yield and crude protein content was measured in laboratory and with the received data the yield per unit area was calculated. Based on the research results we can say that the application of compost in any dose inflicts higher dry material and crude protein yield. The changes were partly due to some positive changes in sward composition, because of the better nutrient conditions. The research results indicate, that use of organic compost can be an efficient way to increase grass yields in a sustainable way.

The effect of silver crucian carp (Carassius auratus gibelio Bloch) on the yields and the production value of common carp (Cyprius carpio) fingerlings
5-10Views:83During the last few years, the spread of the silver crucian carp has caused significant problems in pond fish culture. One of the main challenges of successful fish production in fishponds, is to rid ponds of the silver crucian carp. The nature of the damage caused by silver crucian carp is a complex question. To get into the ponds, the crucian carps occupy the territory before the common carp, and competes for food with common carp. The silver crucian carp has a less favorable food coefficient than the common carp, and it’s value is also lower. Therefore, the income of the fish farm decreases. In the course of the experiment, carp fry were stocked in 5 nursing ponds at the same stocking rate, with different (0,- 50-, 100-, 150-, 200%) stocking rates of silver crucian carp fry, respectively. At the end of the experiment, the yield/hectar and the production values were calculated. The experiment proved that the presence of the silver crucian carp in the fishponds causes lower yields and production values.

Effect of anthocyanin-rich sour cherry extract on the level of IL-8 in LPS-induced endothelial cell
27-30Views:196The anthocyanin content of the Hungarian sour cherry is remarkable. Nutraceutical and pharmaceutical effects of the anthocyanins and their role in disease prevention have been studied extensively. Endothelial cells are involved in the pathogenesis of several inflammatory diseases. The objective of this work was to investigate pure sour cherry extract on human umbilical cord vein endothelial cells (HUVECs) as an inflammatory model. HUVECs were treated with 100 ng/mL lipopolysaccharide (LPS) and 50 mg/mL sour cherry extract or M199 medium as control. The optimal concentration range of the sour cherry extract was investigated and selected based on MTT assay measuring the conversion of the tetrazolium salt to formazan by mitochondrial dehydrogenases. The level of interleukine-8 (IL-8), a pro-inflammatory cytokine, was measured in Luminex MagPlex assay. LPS treatment significantly increased the secretion of IL-8. The pure sour cherry extract was able to attenuate this increment indicating the potent anti-inflammatory effect of pure sour cherry extract. Our results emphasize that pure sour cherry extract could reduce the LPS-induced inflammatory response thereby may improve endothelial dysfunction.

Investigation of the effects of biggame-preserves on forests with different species composition
21-24Views:120Hungary is well known for its high level game management. In order to develop a concentrated and more profitable gamemanagement new game preserves were established in the last few years. According to the law, in the game-preserves the game bearing capacity is not the most important parameter, because in these areas the feeding is continuous. In practice it means that in gamepreserves we find a much higher density of games than in nature. This causes a relative big loading of the area (of the herbaceous and arboreal), where the game-preserves are located.
Our aim is to study the ecological and management issues of forest- and game resources. The scene of these work is a gamepreserves related to the Nyírerdő Corporation (Nyíregyháza). We made forest structure survey to determine the main stand-forming tree species in the area of the game preserves as well as to estimate the number of the measuring points. -
Current Conditions and Opportunities of Biofarming in Hungary
150-156Views:85The aim of organic farming is not to maximize income, but to achieve optimal product quality. It is completed by the tightest possible material, and energy flow within the farm. Organic agriculture significantly reduces external inputs by avoiding the use of chemo-synthetic fertilizers, pesticides and pharmaceuticals. Instead it works with nature to increase both agricultural yields and disease resistance. Total independence of external resources can not be achieved in Hungary due to the small-scale of organic animal husbandry. Some materials in limited quantities can be purchased from external resources, though the group of these materials is strictly regulated. Organic farming harmonizes with the concept of European multifunctional agriculture, because besides farming, it includes social considerations, as it helps to maintain natural resources and the relationship between people and their environment, and provides a living for those living in the region.
As regards organic farming the fertility of the soil and the health of vegetation can be influenced in various ways. Farmers have to be highly skilled and able to manage a farm with great expertise. Generally it can be stated that as the use of non-organically produced products is limited, the opportunities to correct failures made by the farmer are minimal, contrary to conventional farming. Farmers must be intent on developing the tightest material- and energy flow. This means that organic farms ideally have both animal husbandry and crop production. This energy and skill demanding system of farming is compensated by state subsidies, growing market share and relatively high prices for organic products.
