Influencing the growth kinetics of yeast strains with vitamin supplementation
113-115Views:311The aim of the current experiment was to optimize the creation process of single cell protein on plant-based substrate solution with the intention to improve end-product turn out by means of adding vitamin solution. Based on the results of the fermentation processes of yeast strains, it was concluded that the vitamin-supplementation produced its greatest effect on the dry matter production, primarily on the K. marxianus DSM 4908 strain, while it was less beneficent when it comes to the figures of wet cell mass. In addition, it can be assumed that vitamin supplementation increased the maximum specific rate of growth (μmax) and decreased the generation time (tg) significantly. In the case of the K. marxianus yeast strain on corn steep liquor treated with vitamin-supplementation, the highest (μmax) and the lowest (tg) data were observed [(0.226 h-1) and (4.4 h), respectively]. Based on the results it was found that K. marxianus DSM 4908 is expedient to be applied on corn steep liquor medium in order to determine its suitability to produce additive for feeding.

N-fertilization using „Biofert” in Sustainable Maize Production
30-33Views:620In synthetic fermentation of lysine (amino-acid) a by-product (Biofert) originates which can be characterized by 6% N-content and other ingredients (vitamins, enzymes, micro-elements etc). In small and large plot experiments Biofert was studied in different agroecological (cropyear, soil), biological (genotypes) and agrotechnical (non-irrigated and irrigated; N-splitting etc) conditions in order to obtain information about agronomic efficiency and environmental effects of its applications.
Our results proved that Biofert has the same agronomic efficiency as traditional N-fertilizers (applied in equal doses and splitting), but Biofert has economic and environmental advantages (less N-leaching in soils) for maize production. We found a special interaction between N-supply and irrigation. In maize production (irrigation) with the optimum application of nutrient- (N-fertilization, Biofert) and water- supply we could stabilize maize yields at a high level (11.0-14.0 t/ha) fairly independently of agroecological factors. When applying Biofert in autumn, NO3-N leaching was less in 100-200 cm chernozem soil-layers than for applications of traditional N-fertilizer. There were no differences between different maize genotypes concerning the agronomic efficiency of Biofert. In maize production 120-190 kg/ha N (chernozem soil) and 165 kg/ha N (meadow soil) doses of Biofert were the optimum doses in splitting applications (autumn + spring). -
Pricing in the pig production
25-29Views:194During my research work I will exame the state of pig production and the pigmeat trade in Hungary as well as in the EU. In this article I am looking at this branch, I plan to ask consumers about this topic. There is no point in importing pork if there is no market for it. The reality is that we like what is new, unusual and different. What lies behind this way of thinking?
Everybody agrees, consumer habits differ culturally, and this is true in European countries as well. I find it interesting to examine what parts of the pig are favoured the most by consumers in certain countries. As habits are different we can say that certain countries prefer pork chops while on other countries’ menus pork knuckles can be found. If we follow this train of thought it becomes apparent that due to these differences the price of pork varies from country to country.
According to figures, it is clear that certain countries are able to produce pork products cheaper. Since market works on the principle of supply and demand, those who offer their products cheaper will have a greater chance of remaining in this sector. Those on the other hand who can only produce their products at a higher price will eventually disappear from the market. The price is determined by the rate of the forint to the euro. Today’s strong forint is leading to the growth in imports. Recently, pork exports have fallen, but if the rate were to be 280 forints as it has been in the past, then it would be more favourable to sell pork products.
As Hungarian prices are high, meat processing companies are forced to import from neighbouring countries, which means a cheaper source of product. This has led to a decrease in the number of pig in Hungary meaning that we are now an overall importer of pork products rather than an exporter. -
Regional economic achievements and reindustrialisation in Hajdú-Bihar county
65-74Views:736The North Great Plain region is one of the backward regions of Hungary. The low level of economic development is mainly due to the lack of industrial development. The region is poor in natural resources, its main resources are land, natural gas fields, carbon dioxide, thermal water and the clay mineral stock.
The structure of GDP per capita of the county is different than the country average mainly because of the high proportion of agriculture.
The proportion of the industry and the building industry is not significant. Of the various service provider sectors, trade, transport and telecommunications have a small proportion, while financial and economic service providers have even lower share, which is due to the fact that these sectors are mostly concentrated in Budapest. The share of public and human service prodivers is higher than average due to the University of Debrecen.
The GDP which expresses the economic development of the county in a complex way increased four times its previous value in nominal value between 1995–2009. However, if the real value is considered, the increase is less than 25%, as opposed to the country average, which was less than 40%.
The most complex index of the development level of an economy is GDP expressed either in nominal or real value. If expressed in dollars, GDP is suitable for international comparison with the correction based on the purchasing power parity per person.
The county represents 4.3% of the people employed in the industrial sector in Hungary, while its share in industrial production is only 3.3% which is lower than the regional and population share of the county within Hungary. As regards industrial production per person, Hajdú-Bihar was the 10th county in Hungary; therefore, it is considered to be a less industrialised county.
The product structure of GDP is suitable for drawing useful development conclusions, but the result is more reliable if the income creation ability is also analysed on the basis of the employment structure. -
Effects of Site on Winter Wheat Quality 2002/2003
100-107Views:503The demand of modern societies for high food quality is evident. Thus, it is important for agriculture to produce row materials that are valuable for nutrition and have favourable characteristics for food processing. For this we need a knowledge about the factors which determine the quality of products. One of the main features of plant production is the “immobility”. This way the characteristics of the field influence the quality of the product, like example winter wheat, which is the main cereal in Hungary and Europe.
The Concordia Co. has charged the Central Laboratory of Debrecen University, Agricultural Centre with laboratory testing of the 2002/2003 winter wheat crop. The samples consist of thirteen winter wheat varieties from six different sites under the same cultivating conditions. Therefore, the important wheat quality factors were analysed solely against site conditions with the use of Győri’s “Z” index, which contains these parameters.
Soils were tested first. In this experiment excepting the negligible differences between the sites, there were no linear relations found between quality factors, productivity and soil features. The case is the same with the relation between precipitation, temperature and quality parameters. However, it must be noted that additional soil analyses are required to interpret the extreme results obtained from Karcag.
The calculated Győri’s Z-index shows relative stability concerning certain varieties, although considerable deviation can be found in varieties related to the sites. According to these results, it can bestated that winter wheat quality was not linearly influenced by soil and weather in the 2002/2003 vegetation period. As the same cultivation technology was used in the experiment, the index was determined by genetic features. It must be noted that these findings are relevant only to this experiment. -
The effect Benefit PZ biostimulant on the fruit size and yield production of apricot varieties (Prunus Armeniaca)
16-18Views:361Fruit size is determined by the genetic makings of varieties the pomology and enviromental factors. The climate and the previous year’s harvested yield have a great effect on yield volume. It is not easy to harmonize the qualitative and quantitave parameters of the fruit. High yield usually causes smaller fruits.
The aim of our trials was to evalaute the effect of Benefit PZ biostimulant on fruit size. We examined two apricot varieties (Bergeron, Magyarkajszi C235) for the efficacy of the product. The three applications were made with 400 l/ha water with 2500 ppm. The optimal interval of application with Benefit PZ is during in the early phases of development. The size of the final fruits depends on the number of cells making up the fruits. The later application could not increase fruit size growth, there are no significant differences between the Benefit PZ sprayed and the control plots. The totally harvested fruit weight was 13.5% more on the trees of cv. Bergeron, it was caused by the higher fruit set. On the sprayed trees were 12.2% more fruit. Therefore were no differences between the average fruit weight. Fruit weights of the treated trees were 44.37 g on cv. Bergeron, 44.15 g on cv. Magyarkajszi C235 and on the no treated trees were 43.83 g as well as 45.33 g. -
Weed control with herbicide incorporation in sunflower
73-76Views:339During the last decade certificate registration of 13 active ingedients were removed by European Union from sunflower herbicide market, including the basis for the incorporating technology, the trifluralin active ingredient as well. Its relative, the benfluralin active ingredient, which include the Balan 600 WDG herbicide product in sunflower, will be sold again from 2015 spring in Hungarian pesticide market. It has a broad-spectrum and lond residue besides it has very high level selectivity on sunflower. It has very good effect against annual monocotweeds such as common barnyadgrass, foxtail species, large crabgrass and wild proso millet, dicotyledonous weeds such as common lambsquarters,and redroot pigweed. It has significant side-effect against common ragweed, black nightshade, wild buckweed and prostrate knotweed. The long effect residue provide the weed-free til harvest. Benfluralin is totally selective on sunflower, as no colouring, any deformation or growth inhibition was not observed during the entire growing season. It should be sprayed 3-4 days before sowing within 1 hour and to be incorporated into the soil in 4-6 cm depth with tillage equipment. It can be used in tank mix with fluorochloridon in incorporated technology against annual dicotyledonous weeds. After the Balan incorporation can be used postemergence timing imazamox and tribenuron-metil active substances against hard kill and deeply germinating weeds. The products can not be used in tank mix with bacterial products.

Microbiological and Chemical Characterization of Different Composts
106-111Views:179Composting of agricultural waste is considered particularly important from the point-of-view of environmental protection. Degradation of organic substance results in a significant reduction of waste volume.
The end product of the composting process, mature compost, can be used as soil coverage against excess loss of wastes, for mulching, for organic manure etc. The problem of composting has come into limelight in environmental studies and in agriculture.
The quality of the mature compost is determined by physical, chemical and biological parameters of the composting process which, in turn, depend on initial composition of the raw materials, the technology, e.g. regular mixing and moistening and on environmental factors. Quality is the key question in compost use.
We studied the composting process in compost windrows of different raw material composition. We measured temperature, humidity content, pH, organic substance content, nitrogen and carbon content.
We counted the number of bacteria, microscopic fungy, ammonifying and cellulose decomposing microorganisms. We directed the composting process with turning weekly (to provide oxygen) and watering (to provide humidity content 40-60%).
We set up windrows of 1 m3 volume from dry plant substances (cornstalk, pea straw, tomato stalk and crop, weeds) and cow manure not older than 1 week. The cow manure was used at ratios of 0%, 35%, 50%, 65% and 100%, respectively.
We measured changes in compost temperature relationship with outside temperature until they were almoust the same. Humidity was 40-60% in most cases.
At the beginning of the process, pH was slightly acidic-neutral; it later becomes neutral-slightly alkaline (pH: 6.93-8.02) as ammonia is liberated from proteins.
At the end of the process, pH decreased again, due to humification.
Organic substance content decreased as microorganisms mineralized them. Organic carbon content decreased gradually due to microorganisms used it as an energy.
Total nitrogen content increased until middle of july and decreased gradually until than.
The carbon/nitrogen rate were higher in the beginning, it decreased until july-august and increased by smaller degree until end of the process.
The number of bacteria was higher in the first three weeks and between june-september. The number of cellulose degrading bacteria was the highest in the first three month, the number of ammonifying bacteria was the highest from the end of may until sepember.
The number of microscopic fungy was significant in the second part of process, after july. -
Intensity of free radical processes in the leaves of arboreal plants under act of industrial dust borne extracts
83-87Views:189The influence of industrial pollutants on the intensity of lipid peroxidation in the assimilatory organs of arboreal plant was investigated. The differential changes of the probed indexes are set depending on the species. Information is got can testify to participation of lipid peroxidation products in forming of reactions-answers of arboreal plants on influence of industrial dust borne extract with content of heavy metals. Determination of level and rates of accumulation of Zn, Ni, Pb and Cd, in the leaves of arboreal plants in the conditions of different
contamination level allowed to take species to two groups. To the first (phytoextraction potential exceeds a base-line level in 10 times) belong Populus bolleana Lauche, P. italica (Du Roi) Moench, Picea pungens Engelm and Sorbus aucuparia L. To the second (exceeds a base-line level from 5 to 10 times) belong Acer negundo L., Aesculus hippocastanum L., Betula pendula Roth and Tilia cordata Mill. The most substantial increase of peroxidation secondary product content (more than in 2.5 times) is peculiar for B. pendula, A. hippocastanum and P. pungens Engelm., that well conforms to the rates of heavy metals translocation, it has however species-specific character. -
Effect of Storage on Fruitquality of Apricot (Prunus Armeniaca)
164-169Views:346The quality of a product is determined by numerous characteristics. As quality characteristics are polygenic, they cannot be improved easily. Moreover, there often is a negative correlation between the different parameters in the case of apricot. The firmness of fruits decreases with increasing size. The year effect also has a great influence on the expression of the potential quality of the given cultivar.
Our examinations were carried out in 2004 at Boldogkőváralja, in the cold storage plant of the Northcot Ltd. We monitored the development of fruits from fructification until harvest, and also the quality changes during storage. 100 fruits were observed from each cultivar directly after harvest. We measured height, width, weight, firmness, dry matter content and seed weight. From each cultivar, 100 fruits were stored, of which 25 fruits were observed each week. The value and the dynamics of the changes in the parameters compared to the values at harvest varied greatly for the different cultivars. Strong correlations between the parameters have not been found within one cultivar either. The heavier fruits did not lose more weight, either in absolute value or relatively, than the lighter fruits. The increase in the firmness of fruits was not accompanied with a desirable decrease in the dry matter content. -
Scientific background of precision animal nutrition
95-99Views:292Precision animal nutrition consists of meeting the nutrient requirements of animals as accurately as possible in the interest of a safe, high-quality and efficient production, besides ensuring the lowest possible load on the environment. This is facilitated by electronic feeding based on IT technology, an important but by far not the only tool of precision nutrition. In the present paper the following most important elements of precision nutrition are discussed: diet formulation, quality control of ingredients and compound feeds, reduction of the harmful effects of heat stress in pigs with different nutritional tools, application of the recent findings of the molecular genetics in animal nutrition, the relationship between genetics and animal nutrition and reduction of the N and P excretion by nutritional tools.

The effect of feeding different glycerol sources on the performance of lactating sows
99-103Views:339Glycerol is a by-product of the biodiesel industry and it might be a good alternative to moderate the energy deficiency of sows during the lactation period. Preliminary experiments were carried out to test the effect of a powder, solid based “food grade” glycerol source with 72.9% glycerol content (Trial 1) and a liquid “feed grade” glycerol source with 86% glycerol content (Trial 2) on the performance of lactating sows and their litters. Trial 1 was conducted with 5 Hungarian Large White×Hungarian Landrace sows/treatment (313±24.9 kg) and Trial 2 with 12–12 DanAvl (323±17.0 kg) sows and their litters/treatment. Neither the solid, powder based glycerol (Trial 1), nor the liquid glycerol source (Trial 2) had significant effect on the feed intake, reduction in live weight and back-fat thickness, and weaning-tooestrus interval (p>0.05) of lactating sows. In Trial 2, on the 14th, 21st and 27th days of lactation the milk samples were collected and it was found that 50 kg/t glycerol decreased the protein content of milk samples (p<0.05). Glycerol supplementation had no effect on dry matter, fat, lactose content of milk samples (p>0.05). In Trial 2, no significant difference was found between control and experimental sow groups in triglyceride concentration of blood samples and in the activity of liver enzymes (ALT, AST, GGT; p>0.05), but the concentration of plasma glucose and cholesterol increased tendentiously (p<0.10).
Based on our preliminary results, it can be concluded that additional dose trials are needed to perform in order to study the effect of glycerol supplement on milk production and on metabolic processes of lactating sows.

Economic issues of crop based ethanol production for energetic uses
90-94Views:246The United States Congress passed the “Clean Air Act” in 1990, which targeted the creation and use of so-called “green fuel”. This Act came into full force on January 7, 1995. Its essence is that an oxygen rich component is added to fuel by which it burns more cleanly and harmful emissions of vehicles are reduced by 25%. This oxygen rich component is basically ethanol and its ether ETBE, made of domestically produced grains.
America’s traditional grain exporter status could be converted into a stabile income resource during production, many more valuable by-products – should this program succeed – are also produced, giving the opportunity for further utilisation either in the foods or form feeds industries, or as export products.
Ethanol or ETBE production is also important to replace fuel imports from any specific country, the additive which is necessary for producing the fuel is the imported product MTBE.
This programme therefore simultaneously assisted in environmental protection, agricultural and foreign trading issues as well as some market regulation issues. At the same time, based on grain production, it has an effect on the social strata by creating new jobs, especially in those areas which can be considered in recession due to the lack of any large-scale industrial cities.
In the future, the European Union should carry out this project and it will affect Hungary, as well. -
Evaluation of technologies and resources from the spatial and social aspect
73-75Views:565The basic functioning of the world is mostly led by negative trends. One of the fundamental reasons for this phenomenon is that the different technologies (hardware, software, resources) do not act properly and in the proper structure by means of the produced products and services. Therefore, the examination of technologies and resources is a key question of our world and development from various aspects. Technologies convey all positive and negative impacts which can be regarded as the fundamental reasons and causes of harmonious or disharmonious development. For this reason, the role of technologies in development and harmonious functioning is of paramount importance.
As a final conclusion, we established that the different technologies (hardware, software, resources) are interpreted as impact conveyors which predominate by means of products and services in a way that their relation system is determined. By using the thermodynamic interpretation which is the basis of the functioning of the world, we built a system consisting of 14 elements to evaluate different technologies, to interpret its functioning and to develop positive interactions and trends.

Result of Wine Consumption Survey
387-393Views:257Wine has always played an important role in the Hungarian culture and gastronomy. Today, average wine consumption is about 33 liter per person per year, which figure, comparing with datas in Western Europe, is acceptable. However, cultured wine consumption has begun to develop only in last few years. Consumers, whose knowledges about wines have been widening, demand quality wines. The number of high standard scientific contributions on this subject has risen greatly. But comparisons of them are rather difficult because of adopting different surveying methods. This research has supported and confirmed that wine is a confidental product and previous experience could be an important determining factor during wine-purchasing. Wine is popular as a present, so the nice, elegant look, proper bottles and labels are essential for the higher rate of selling. Further, price-value rate could also be a main factor during the customers’ decision. This survey is a result of a test-research and its methodolical experience will have been used in my following researches.

Effect of vitamin e and selenium supplementation on the antioxidant content of milk and dairy products in dairy cows
9-12Views:432In 2007, the aim of the Ányos Jedlik program and the call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants - in this case: vitamin E and selenium – used as feed-additives can increase the antioxidant content of milk. The milk with an increased level of vitamin E and selenium content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E and selenium as feedadditives can significantly increase the amount of vitamin E and selenium in the milk and also in the diary products.

The role and impact of N-Lock (N-stabilizer) to the utilization of N in the main arable crops
51-55Views:387The nitrogen stabilizer called N-Lock can be used primarily with solid and liquid urea, UAN and other liquid nitrogen, slurry and manure. In corn it can be applied incorporated before sowing or with row-cultivator or applied with postemergent timing in tank-mix. In postemergent timing need precipitation for long effect. In oil seed rape and autumn cereals the N-Lock should be applied with liquid nitrogen in tank mix late winter or early spring (February-March). The dose rate is 2.5 l/ha. N-Lock increases the yield of maize, winter oil seed rape, winter wheat and winter barley 5-20 %. The yield increasing can be given the thousand grain weight. In case of high doses of nitrogen it can be observed higher yield. The quality parameter also improved, especially the oil content of winter oil seed rape and protein and gluten contents of winter wheat. The use of N-Lock increases the nitrogen retention of soil and reduces nitrate leaching towards the groundwater and the greenhouse effect gas emissions into the atmosphere. The degradation of the applied nitrogen is slowing down and the plant can uptake more nitrogen in long period. The effect of N-Lock the nitrogen is located in the upper soil layer of 0-30 cm and increasing the ammonium nitrogen form. The product can be mixed with herbicide products in main arable crops.

The Present and Future of Tokay Aszú
87-92Views:243Tokay wine is Hungary’s noblest wine. Beyond doubt, it is one of those uniquely Hungarian products, which has been without rival for centuries. Today the role of quality has become increasingly important and consumers who are ready to pay more for quality wines expect it. This wine will be able to get back its original popularity if the message of its excellence reaches the public. Knowledge of historical wine-producing regions constitutes a part of basic education and wine-marketing could take important measures to spread it since good products need to be sold properly and consumers require information about wines – with gastronomy – and wine producing regions.
With foreign invested capital, advantageous changes have been started in Tokay-Hegyalja. However, there is much still to do in order to produce, sell and consume Tokay wine on such conditions that are really worthy of a Hungaricum. It is essential to approach the famous oenologists of Europe and the world and to establish suitable production conditions for every winegrower. In addition to following consciously prepared wine-marketing directions, our country needs to make an expected name for this Hungaricum. These aims are important mainly because of approaching EU-accession. There is timely to study on what conditions Hungarian viticulture and oenology could access. It would be a great success of the Hungarian delegation if they could make current Hungarian laws of Tokay-wine-production accepted in the EU. Of course, all of these would be valid after EU-accession. During the pre-accession period, our country needs to fulfil several stipulations. For example, origin-protection, establishment of a registry system, law harmonisation, development of an institutional system.
Strengthening of home consumption has always been an inspirational tool in a product’s life cycle. It is important not only to take the requirements of foreigners into consideration and to produce for export, but we also need to satisfy the home market. Considerable stress should be laid on establishing and preserving viticulture. Increasingly, buyers expect high standards and they are ready to pay more for quality wines. They also demand appropriate professional information and consultation. So there is a lot to do and theoretical approach should be followed by action. In order to get to know what quality expectations exist, we have to examine the consumers of the Hungarian wine-market. Study of the Hungarian people’s consumption behaviour, referring to Tokay „aszú”, was closely connected with my work.
Participants of my study were consumers who buy Tokay „aszú” mainly in shopping centres, supermarkets and low-price shops specified for wine selling. Wine shops have important roles as they give opportunity for salespersons to make closer relationships with buyers. These shops could be communication channels of spreading wine culture. It would be favourable if in every town or city there were at least one wine shop giving the opportunity of consultation besides commercial activity and also providing services that support the improvement of wine culture’s position. The majority of questioned people spend less than 4.000 Forints on buying of Tokay „aszú” in a year. Results of the questionnaire survey support the fact that there is a demand for these wine-specialities, but lack of money strongly effects demand.
The Following summarises the history of Tokay wine, tasks of Hungary and the expected effects relating to EU-accession. Regulation of oenology and the wine-market, referring to quality wines and main results of the survey are also overviewed in the text. -
Realisation of customer focus from quality and forage safety aspects in the Hungarian mixed feed production
35-38Views:217Customer focus is one of the main principles of Total Quality Management, and it is inevitable for long term, mutually successful vendorcustomer partnerships. The strictly controlled quality management systems of animal feed industry ensure that product quality meets the expectations of all parties involved and, indirectly the reliability of human food raw materials. Meanwhile, the participants of agricultural production are variably quality conscious, so feed manufacturers support their supply chain and also their customers with professional background and they play a key role in safe food chains from farm to fork.

The effect of β-glucan, carotenoids, oligosaccharides and anthocyanins on bacteria groups of excreta in broiler chickens
15-20Views:860This study was conducted to examine the effect of natural compounds, such as β-glucan, carotenoids, oligosaccharides, and anthocyanins in the diet on bacteria gropus of excreta in Ross 308 broiler chickens. Chickens were fed 5 diets: control (basal) diet, a diet supplemented by β-glucan at 0.05%, and diets supplemented by carotenoids, oligosaccharides, or anthocyanins at 0.5% of each compound. On experimental day 19, excreta were collected to determine the proportion of Lactobacillus, Bifidobacterium, Campylobacter, Clostridium, and Escherichia coli. Samples were collected aseptically and snap-frozen in liquid nitrogen. Bacterial DNA was isolated from samples, then polymerase chain reaction using primer pairs designed to the 16S rDNA of bacterial groups were applied to define the proportion of the mentioned bacteria. Another universal primer pair was used to amplify a region of 16S rDNA of all the examined bacteria. Proportion of each bacterial groups was determined relatively to the intensity of universal PCR product band by gel documenting system and ImageLab software. Based on the results, carotenoids and anthocyanins increased the proportion of Bifidobacterium, which might imply the beneficial effects of the mentioned compounds on the bacteria composition of excreta.

Regional Development Differences in Hungary and the Northern-Great Plain Region
62-71Views:512The most important endeavour of European Union’s regional policy is to moderate disparities. An emphasised strategic objective of member states, based on the principle of solidarity, fairness and justice, is to develop regions and almost forty percent of the common budget is devoted to achieving this objective.
Hungary, as a full EU member state, will get a new chance for underdeveloped regions, especially for the Eastern-Hungarian as well as the North Hungarian and North Plain Region.
The differences in development among the regions are significantly influenced by the economic characteristics of the specific region, quality and quantity of human resources, accessability of the region and other factors influencing local quality of life beside natural conditions.
The new spatial structure was formed by change of regime, processes of the nineties, primarily the economic renewal based on foreign capital investments and the crisis phenomena in parallel with these. The economic, political and social consequences of the transformation significantly changed spatial structure and increased disparities. New disparities formed which were further aggravated as a consequence due to the formation of the eastern-western slope and local crisis zones. As a result of the outstanding development of the capital, the long term differentiation of regional development differences can also be detected when examining the regional distribution of Hungarian gross domestic product. The collapse of heavy industry and agricultural mass production based on the eastern markets primarily affected the north-east counties in the eastern part of the country.
Strengthening regional competitiveness is of key importance for the region, which requires the application of consistent development policy. The most important is economic development which, if it operates well, also infers the possibility of establishing welfare infrastructures. Drawing in external sources to ease the significant lack of capital is important for the processing industry and the development of supplier networks. Agricultural development also plays an important role in transforming economic structure, since the characteristics of the region, its traditions and long term competitive advantages are favourable, therefore it is going to represent a higher ratio within the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting market accession, quality agricultural production and stimulating producer-retailer cooperation. The development of transportation and informatics infrastructure as well as human resource development plays a significantly important role in the development of the region.
In conclusion, the implementation of such a consistent regional development policy is required in the future, based on the strengths of the region, that serves the most efficient utilisation of regional development funds through the implementation of regional policy principles and prevents the irreversible decay of the region while promoting rapid development. -
Some basic problems concerning world animal production at the beginning of the XXI century
77-80Views:250The author summarizes the main new challenges facing animal agriculture: growing GDP in many countries increasing animal protein demand, bioenergy industry as a new player using potential food or feedstuffs, increasing demand, Growing water and land scarcity, weaking the position of plant agriculture, feed production. Forecasts are summarized regarding the magnitude of meat consumption increases, and the possible plant biomass quantities required additionally in the next 20 years to cover the needs of food, feed and biofuel on a global scale.
Efficiencies of various animal production sectors, poultry, pork, beef, mutton meat, milk and eggs and their environmental footprints are compared, summarizing the most important research results concerning UK, USA, OECD evaluations. Intensive systems using highly productive plant and animal population will play an even more important role in the future especially in poultry, pig, milk and aquaculture production system being efficient users of resources (feed, water, land) and the environmental foot print is smaller per unit product. -
HPLC-MS analysis of the active ingredients of chamomile (Matricaria chamomilla) bee feeding syrup
61-65Views:714Apiarists 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.

Data supporting the quality of sheep milk for processing
67-73Views:353Although the volume of ingredients in ewe’s milk is substantially higher than in cow’s milk, its hygienic quality is lower. The weak quality of raw ewe’s milk limits the possibilities of processing and results in bad quality products. In our investigation we analysed the state of ewe’s milk processing at a typical medium size dairy firm. We investigated the collection, the amount and the quality of milk and the level of ingredients in milk throughout the purchasing period (lactation period).
The purchasing of ewe’s milk was limited to 5 months (from April to September). Although meat (lamb) provides the major source of income to sheep breeders the extension of the period of ewe’s milk production can be beneficial to shepherds and dairy firms. The amount of ewe’s milk ingredients found corresponded to published findings. However, the hygienic quality of ewe’s milk was varied greatly in the different milk samples and these deviations meant bad quality on average. Physiological factors, the circumstances of sheep breeding and milking, the slow cooling of the milk, the little amount of daily milk and the long storage before transportation to the dairy firm together cause poor hygienic quality. The main problem is the long storage time of milk, but our results raise the question of reconsidering the quality classes. Investigating the effect of the hygienic quality of raw milk on product quality, we can get correct data that can be really authoritative. -
