    21-27

    The authors of this study seek the answer to the question how to develop, in the first decade or decades of the 21st century, the university-level
    horticultural scientific training, the horticultural innovation and the scientific co-operation between companies and universities in Debrecen and
    in the North Great Plain Region and – in a wider sense – in Hungary to a standard being competitive even in European terms. With the synthesis
    of the prospects of past, present and future, they drew the following conclusions. The reconstruction of agriculture, horticulture and food industry
    is a part of reforming Hungary's countryside. Horticulture, producing high added value, will be able to decisively contribute to the plan whereas
    the value presently produced in an agriculturally cultivated area of 1,000 euros/hectare can reach 2,000 to 3,000 euros in the next two decades.
    A necessary and indispensable precondition to achieving this is the strengthening of the innovation output of the Hungarian horticultural sector.
    Despite the numerous technical criticisms formulated in connection with the serious problems of Hungarian agricultural and horticultural
    scientific innovation, no progress has been made in this field for the past one and a half decade. The scientific research of this topic hardly
    continued or did not continue at all, the up-to-date surveys and in-depth analyses were missing. The objective, basic principles and tasks of the
    Act CXXXIV of 2004 (TTI) enacted concerning research-development and technological innovation are clear and progressive. The co-operation
    between the National Research Technology Office and the Hungarian Academy of Sciences, the setting up of the Innovation Fund are heartening
    opportunities. These – along with the new Higher Education Bill to be passed – may as well be suitable for restarting the Hungarian agricultural
    and horticultural scientific innovation. In our opinion, this requires a new, well-considered national agricultural programme, which can be
    conceived in the framework of the "Ferenc Entz National Horticultural Plan" proposed by us for horticulture. In the most eastern Hungarian
    university knowledge centre, at the University of Debrecen, the continuing of the horticultural scientific innovation strategy started in the last
    decade may be the focal point and generator of the development of the so-called "Hungarian Horticultural Triangle”, or "Hungarian
    Horticultural Cluster". This region comprises the Northern and Southern Great Plain Regions and the area between the Danube and Tisza
    Rivers. Here, about 70 to 75% of the total Hungarian horticultural commodity stock is produced. The objective of the HORT-INNOTECH
    DEBRECEN programme planned in 2004 by the University of Debrecen, Centre of Agricultural Science is to establish the horticultural scientific
    research-development and technological innovation structure and knowledge base of the Hungarian Horticultural Triangle / Hungarian
    Horticultural Cluster. In harmony with this, the objectives are to bring about competitive, new horticultural products, to improve the conditions
    of utilising them, to enhance the competitiveness of enterprises based on technological innovation, to make use of the research-development and
    innovation opportunities available in the regions in an efficient manner, to as full extent as possible, to encourage the creation of places of
    employment producing high added value in the field of horticulture, to improve the technical skills of those employed in horticultural researchdevelopment and to promote their enhanced recognition by the society.

    Fattening and slaughtering characteristics of both types (black and white) of the Hungarian racka sheep were investigated at the site of the National Institute for Agricultural Quality Control in Atkár. The Hungarian merino, the dairy cigaja and the British milksheep were applied as control groups. 10 animals were examined from both sexes in each genotype. The examination was carried out according to the principles set in the Codex for sheep breeding. During the test acute diarrhoea occurred in each control group. However, only few lambs were excluded from the test from the British milksheep and the Hungarian merino groups because of significant changes in their condition. Consequently, the results obtained were not significantly influenced. No symptoms of any illness could be recognised in the Hungarian racka sheep, though. The significance of the difference between the average of the examined groups were checked by T-tests.
    Daily gain was significantly less compared to the control groups, except for the white racka males. The lambs starving for 24 hours before slaughtering weighed 25.3-30.0 kgs on average. The black and white racka females weighed the least while the Hungarian merino females weighed the most. The quantity of abdominal and kidney fat was significant in the case of our native females. The quantity of abdominal fat was significantly bigger compared to each control group. On comparing the investigated groups it turned out that the white racka males had the biggest skin weight while the white Hungarian racka females had the smallest, that is the two extremes were recognised in the same colour (white) of one bred. On qualifying the slaughtered animals females had better results than males in each bred; the racka sheep were better than the dairy cigaja but were worse than the Hungarian merino and British sheep groups.
    The huge differences in the carcasses of the groups were seen clearly when chopping. Examining the leg, it was noticed that the native groups proved to be smaller than the control groups, except for the black racka males. As for the short loin, the Hungarian racka and the Hungarian merino sheep proved to be the best, whereas the dairy cigaja and the British milk males had much smaller ones. The results gained when investigating the rack were similar to those of the short loin. As far as the rib and shoulder are concerned, the black racka females and the dairy cigaja females had the worst results. After chopping, the right side was also boned in every group. The small proportion of bone in the case of racka sheep was easily noticeable that resulted in the fact that the white racka females had the highest quantity of short loin compared to the other groups. When examining the back quarter, the bone proportions of the 4 racka groups proved to be significantly less than those of the control groups but it was not true for the meat proportions. As for the front quarter meat, the racka males were prominent in the great shoulder meat and in the small proportion of bone. The quantity of the first quarter bone was the least in the case of racka sheep and was the biggest for dairy cigajas. This difference proved to be significant in most cases.
    In short, the Hungarian racka groups had the best results in meat quantity, which was especially significant compared to the dairy cigaja sheep. However, the quantity of external fat increased.

    Different goldfish types play an important role both in ornamental fish farming and science. Considering its historical background, the goldfish is a suitable model animal for the study of artificial selection as well as for developmental biological studies. Sperm motility and cell density is an important parameter in determining sperm quality. The aim of our study was to examine the effects of different goldfish types on the sperm quality. Several sperm motility parameters (progressive motility (pMOT, %), straight line velocity (VSL, μm s-1), curvilinear velocity (VCL, μm s-1), linearity (LIN, %), amplitude lateral Head Displacement (ALH, μm), Beat Cross Frequency (BCF, Hz)) of four different goldfish types (Common goldfish-“wild type” N=5, Shubunkin N=4, Black Moor N=4, Oranda N=5) was compared during 60 hours (at 12-hour intervals) at refrigerated storage (4 °C). The variability of sperm density was also investigated in all types. A similar cell concentration was determined in the four goldfish variants (Common goldfish 2.01*1010 ± 3.46*109; Shubunkin 1.71*1010 ± 3.25*109; Black Moor 1.66*1010 ± 3.02*109; Oranda 1.56*1010 ± 5.83*109). Statistically significant difference between the 4 goldfish types in the motility parameters and cell density was not noted. However, a decreasing tendency in Black Moor sperm motility parameters (pMOT, VCL and VSL) was observable, as well as a reduced spermatozoa density in Oranda was also recorded. Our results can contribute to the improvement of the common hatchery propagation of goldfish. Future studies can add more evidence of the possible effects of artificial selection on the reproduction in different goldfish types.

    In our examination, we evaluated Hungarian Merino (ram n=30, ewe n=30), Ile de France F1 (ram n=10, ewe n=10) and Suffolk F1 (ram n=10, ewe n=10) lambs. The best fattening performance was shown by the Ile de France F1 lambs (361 g/day). After the fattening period, Hungarian Merino, Ile de France F1 and Suffolk F1 genotypes lambs were slaughtered with a live weight of 30-34 kg. Carcasses were evaluated for dressing percentage, weight of valuable carcass cuts, percentage of valuable meat, bone to meat ratio, as well as meat conformation and fat cover (S/EUROP grading).
    The slaughter performance proved to be the best for the Suffolk F1 concerned dressing percentage (51,7%), percentage valuable carcass cuts (81,9%). The best percentage valuable meat presented (79,4%) the Ile de France F1 lambs. The best meat conformation and fat covered were in the Suffolk F1 lambs; Hungarian Merinos showed less favourable results.
    Presently, the results derived from Hungarian practice that Hungarian Merino lambs are not eligible for fattening to great live body weight (30 kg). Therefore, it is necessary to revise the Hungarian Merino lambs with meat sheep breeds.

    The aim of our examination was to detect the puberty of the Hungarian Merino and its hairsheep crossbred ewes, and also to determine their average conception rates after having ram exposed in May and June. Hormon diagnostation was used to evaluate the exact date of the very first ovulation. Ultrasound technique was used for checking the conception rates of ewes. The pregnancy detection was applied after a month of the date of taking off the ram.
    We evaluated the ages of ewes at puberty. Statistical deviation and standard error were calculated. The results proved the Hungarian Merino x Somali (N=10), ((x ± s) = 173 ± 43) and also the Hungarian Merino x Barbados Blackbelly crossbred genotypes (N=7), ((x ± s) = 186 ± 19) have their puberty much earlier as compared to the fullbred Hungarian Merino ewes (N=10), ((x ± s) = 231 ± 95). We experienced the highest conception rate in the group of the (Hungarian Merino x Somali) F1 ewes after exposing the ram in the „out-of season” period of time.

    The Hungarian Large White and Hungarian Landrace pig breeds have outstanding lifetime performance, production parameters and crossbreeding ability. Nevertheless, during the recent decades, these breeds could not compete with the West European hybrid pigs concerning on production results. In this study, we made a complex andrological evaluation of boars in different Hungarian nucleus breeding stocks. After taking blood and semen samples, performing gonadotropin-releasing hormone (GnRH) challenge, ultrasonic and thermographic examinations were done. Laboratory tests were accomplished in reproduction labs of NARIC ABNMS. Our goal was to determine the reproductive performances of boars and collect samples for future genetic examinations, respectively.

  • Life in two countries but one home land – Béla Lipthay (1892-1974) the entomologist

    Béla Lipthay lepidopterologist, entomologist, museologist, agriculturist, hussar lieutenant, life-saving Roman Catholic, descendant of the historical family Lipthay de Kisfalud et Lubelle did a long way from his home village Lovrin to Szécsény, the one-time land of his ancestors. His life coincided with the disintegration of the historical Hungary, and the most serious trials of the Hungarian society, culture and spirit. These changes affected him as a member of Hungarian aristocracy many times and in fact wanted to destroy him. The fortune of the ancestors have been swept away by the storms of the wars and confiscated but the human strength of character, the consciousness, the talent, the diligence, the sanctuary of faith have remained. All these made him possible to survive, to do his everyday hard creative work, which gained him affection and respect of the people living around him.

    Lipthay Béla was mainly lepidopterist and dealt with the the species of Hungary. Place of his collection was first his native country, the Banat, and the area of the Southern Carpatian Montain, and after 1944 Nógrád county (Szécsény, Balassagyarmat, Nógrádszakál, Ipolytarnóc, Rimóc, Ludányhalászi etc.). The collected species belonged to Macrolepidoptera but he dealt also with the moths. During his life time he prepared a collection of 60000 individuals and maintained them until his passing away. Great part of this collection can be found at the zoological cabinet of Natural History Museum in Budapest. He discovered many species new for the Hungarian fauna such as e.g. Cupido osiris (Meigen, 1829), and described a new species (Chamaesphecia sevenari Lipthay, 1961) which later proved to be a synonym of Chamaesphecia nigrifrons (Le Cerf, 1911). He knew well the most famous collectors and specialists of the age. After the first World War he worked together with Frigyes König, László Diószeghy, Jenő Teleki, Norman D. Riley (leading entomologist of the British Museum at London, secretary of the Royal Entomological Society), Brisbane C. S. Warren ( member of the Royal Entomological Society), Lionel W. Rothschild (the most important private collector) and many excellent lepidopterists. After the second World War he was well known and respected by the Hungarian entomologists and lepidopterists: he was a friend of Lajos Kovács, the distinguished lepidopterist and Zoltán Kaszab, the eminent entomologist. He had a good relationship with such renowned Hungarian zoologists and entomologists like Gyula Éhik, László Gozmány, László Issekutz, László Bezsilla and László Móczár. He colleted also Hymenoptera, Diptera and capricorn beetles to be found in Hungarian and foreign collections Natural History Museum, (London), a Szekler National Museum (Marosvásárhely). He dealt with agricultural entomology because he was an experienced agriculturist as far as he had the opportunity to do that. He painted wonderful agricultural entomology posters and organized expositions e.g. on the pests of industrial crops and hunting at Balassagyarmat and Salgótarján.

  • The Present and Future of Tokay Aszú

    Tokay 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.

  • Influence of nitrogen fertilisation on the technological quality of wheat

    Wheat is one of the most grown crops around the world. Its primary use is in the production of bread, bakery, and confectionery. The provision of essential nutrients, mainly nitrogen, plays a pivotal role in the growth and development of wheat. The wheat varieties used in the experiment are Alfold and Mv. Menrot. The rates of nitrogen used in the experiment are: 0, 200, 400, 600, 800, and 1000 kg N ha-1. The aim of this study is to evaluate the effect of nitrogen fertilisation on technological quality of wheat and to find the appropriate fertiliser rate to reduce pollution. The results indicate that nitrogen fertilisation did not show a significant effect on thousand kernel weight and test weight. However, nitrogen fertilisation significantly affected protein content, gluten content, Zeleny sedimentation index, and the falling number. The higher the nitrogen fertilisation the better the technological quality parameters of the wheat. The protein content, gluten content, Zeleny sedimentation index and the falling number were the lowest at 0 kg N ha-1 followed by 200 kg N ha-1 then 400 kg N ha-1 and the highest at 600 kg N ha-1.

  • Complex problem analysis of the Hungarian milk product chain

    Hungarian dairy sector went through significant changes in past two decades. The most significant changes were caused by our accession to the European Union. In Hungary milk production remarkably declined after EU accession. The size of our dairy herd has been practically reducing since the political transformation, but increasing yields per cow could compensate it in some way and for some time. However, in recent years, increasing yield per cow came to a stop and in parallel, the number of cows declined further and faster. Low prices, high production costs and tightening quality requirements ousted several producers from the market in past years. Feeding cost represents the highest rate in cost structure of production, but animal health expenditures and various losses are also significant. There are undeniably competitive disadvantages in the level of organisation and labour productivity; however competitiveness already depends on cost effectiveness in the medium run. In Hungary concentration of the dairies is relatively strong in spite of the relative high number of corporations. The dairies compete with each other and with the export market for the raw material and the better exploitation of their capacities. Applied technology of the Hungarian dairies lags behind the Western-European competitors’; in addition they have handicaps in efficiency and product innovation. Presence of chain of stores being dominant in sale of milk products does also not favour in all respects to the position of the dairies. The aforementioned retail chains are namely consumer-centric, engage in price follower conduct and weaken the position of the dairies with their private label products. As a result of increasing import of milk and milk products Hungary became a net importer in recent years. Today, disposable income still essentially determines the consumption habits of price-sensitive consumers. Loyalty for Hungarian products is not typical, consumers are open for import products being preferred by retail chains. In addition Hungarian milk and milk product consumption is about half of the Union average and it is far behind the level being necessary for healthy eating. In Hungary lack of competitiveness and vertical integration relationships and backwardness are revealing among the dairy farmers and the dairies, while chain of stores are in unprecedented “monopolistic situation”; the whole sector can be characterised by defencelessness.

    The effect of mycorrhizal fungi and plant growth promoting rhizobacteria on some physiological properties, yield and soluble solid content (Brix) of ‘Uno Rosso’ F1 processing tomato was studied under water scarcity. Inoculation was performed with mycorrhizal fungi (M) and rhizobacteria preparation (PH) at sowing (M1, PH1) and sowing + planting (M2, PH2). The treated and untreated plants were grown with regular irrigation (RI = ET100%), with deficit irrigation (DI = ET50%) and without irrigation (I0). In drought, the canopy temperature of plants inoculated with arbuscular mycorrhizal fungi (M1, M2) decreased significantly, however, the decrease was small in those treated with the bacterium (PH1, PH2), while the SPAD value of the leaves of plants treated only with Phylazonit increased significantly. On two occasions, inoculations (M2, PH2) significantly increased the total yield and marketable yield, however, under water deficiency, a higher rate of green yield was detected than untreated plants. In dry year using deficit irrigation, the one-time inoculation (M1, PH1) provided a more favorable Brix value, while the double treatments reduced the Brix. In moderate water scarcity, the use of mycorrhizal inoculation (M2) is preferable, while under weak water stress, the use of rhizobacteria inoculation (PH2) is more favorable.

  • Inheritance of Plant and Ear Height in Maize (Zea Mays L.)

    Plant and ear height are very important characters not only for describing new varieties of maize (Zea mays L.), but for green and dry matter production, and even for grain yield. Significant positive correlations have been reported by various authors between plant height and stover yield, plant height and dry matter yield, and plant height and grain yield. The height of the main ear is also correlated to plant height. It depends on the variety or the environment, but is likely to be the same height within a population. Many environmental and agronomical factors (e.g. plant density, fertilization, pests and diseases) influence the expression of these characters, which are not quality traits. Their expression is controlled by many genes and by the interactions between these genes. The heritability of these traits is high and they show significant genotypic variability and positive heterosis, as reported in many research publications.

  • Wine market trends in the EU and Hungary

    Traditions of the Hungarian grape and wine sector go back centuries. However, although this sector is proud of its rich traditions, it has gone through several shocks. Having joined the EU, Hungary has become a part of the integrated internal market. The commercial obstacles and difficulties among EU-members and Hungary have officially been removed. At the same time, within the Common Agricultural Policy, the wine market has been organised at community level by EU-members. There is no possibility for the sector to access any kind of direct supports from the Hungarian budget, unless such activity is definitely allowed by community directions or unless Hungary were authorized in the framework of a supplementary procedure. After joining the EU, the customs-protection - which aim was to protect the EU-market against the third countries - reduced, so wine producers from overseas countries emerged with their competitive wine prices in the home market and also became competitors of Hungarian wine producers who have been working under low technically equipped conditions. In order to increase the competitiveness of Hungarian wines, it is essential to improve the machinery of producers and to improve the equipment of winecellars. Finally, it is also vital that Hungarian wine producers develop a well-constructed marketing policy.

    Modern animal husbandry has drastically changed the genetic structure of some domestic species. The varieties, genotypes that we think we do not need at the moment can only be saved from extinction with the help of gene conservation. Traditional Hungarian horse breeds have a long history (more than 200 years) and a demonstrably different genetic structure from other horse breeds in Europe and the rest of the world. Consequently, their enormous genetic value is undoubted. The subject of our research was to study the structure of the mare families found in the population of the Lipizzan horse breed and the genetic structure of the Hungarian population. Out of the total 61 mare families in the world, 35 are present in Hungary. There are 11 Hungarian, 12 families of Fogaras, 7 original, 4 Croatian and 1 Slovenian mare families in the Hungarian population. The proportion of mare families in Hungary and Fogaras is almost the same. The proportion of Croatian and Slovenian families is negligible. In terms of their number, they are not significant in Hungary. For this reason they have little effect on the Hungarian Lipizzan population. Except one of the original mare families are in the same situation as the Croatian and Slovenian families. The Presciana / Bradamanta mare family is the most populous of all families due to their long stay in Hungary. The proportion of families is unbalanced. Seven mare families accounting for 56.36% of the total population. Given the basic requirements of gene conservation work, this condition is far from optimal.

    Essential oil extraction of wild caraway and thyme was performed using a classical (HD) and microwave hydro-distillation (MWHD) and a laboratory supercritical fluid extraction (SFE) with a carbon dioxide as solvent. Our experiments demonstrated that the extraction yield of the essential oil performed in same conditions was influenced by the location of growth area; the maximum extraction yield of 10 ml 100 g-1 caraway was obtained from dried seeds collected from Csíkmadaras. This quantity far exceeded the yield of the Újtusnád samples. In the case of wild caraway (Carum carvi L.), the extraction method influenced thecomposition of the essential oil (carvone/limonene ratio), the highest limonene content being achieved by classical hydro-distillation. In the case of thyme, this effect was not detected, the thymol/carvacrol ratio was independent from the given extraction method. The obtained thyme essential oil possesses high antimicrobial activity demonstrated by agar diffusion test. The thyme extract provides a good protection against microorganisms collected on the surface of fresh vegetables following bacterial stains: Citrobacter portucalensis, Pseudomonas hunanensis, Pseudomonas baetica, Pseudomonas parafulva, Bacillus mojavensis and Enterobacter cloacae. Protective effect was also detected on the vegetable surface of by chitosan-based edible film coating during a 6-day-long storage period at a temperature of 4 °C. The caraway essential oil used as soft cheese seasoning with a direct, dilution-free method, proved to be unsuitable because the uneven distribution and confer a strong, unpleasant taste to the product in comparison with the ground wild caraway seed-dressed cheese.

    Our objective was to analyse the situation of Hungarian language agricultural higher education in Romania. Our analyses have been focused mainly on Kovászna county. Following the evaluation of the characteristics of the county, we assessed the situation of Hungarian language higher education in Romania. History is considered important, because Hungarian language agricultural higher education goes back to the 1860s. The best solution for measuring the current reputation was the completion of questionnaires, which was done by 140 randomly selected people in Kovászna county. Following the evaluation and analysis of the questionnaires we found that local agricultural education, plant production and livestock farming are important activities for the locals. However, it is sure that even if they are satisfied with the education, they consider continuous development very important, since it would be a major help for the employment and subsistence of fresh graduates in Kovászna county.

    When preserving genetic resources, one of the most important tasks is to conserve as much of the given gene pool for the future generations as we can. Therefore, traits that have no economic value at the moment should also be conserved. The great variety of coat colours seen in the Hungarian Grey cattle form part of the world’s genetic heritage. In order to maintain the world’s genetic diversity, we have to maintain these varieties, as well. The different coat colour varieties were determined – in both sexes and in several age groups – with a Minolta Chromameter CR-410 in an objective way. We found that the rate of the three main coat colour varieties of calves: the light reddish, the reddish and the dark reddish were 26%, 52% and 22%, respectively. Statistically significant differences were found between the L*a*b* values of the reddish coat colour of the Hungarian Grey and the red coat colour of the Limousin calves. The rate of the crane, the grey and the light grey coat colour varieties were determined in the measured female groups. The L*a*b* values of the Hungarian Grey and Maremman bulls’ coat were compared and evaluated.

    The aim of the current research was to estimate variance components and genetic parameters of weaning weight in Hungarian Simmental cattle. Weaning weight records were obtained from the Association of Hungarian Simmental Breeders. The dataset comprised of 44,278 animals born from 1975 to 2020. The data was analyzed using the restricted maximum likelihood methodology of the Wombat software. We fitted a total of six models to the weaning weight data of Hungarian Simmental cattle. Models ranged from a simple model with animals as the only random effect to a model that had maternal environmental effects as additional random effects as well as direct maternal genetic covariance. Fixed effects in the model comprised of herd, birth year, calving order and sex. Likelihood ratio test was used to determine the best fit model for the data. Results indicated that allowing for direct-maternal genetic covariance increases the direct and maternal effect dramatically. The best fit model had direct and maternal genetic effects as the only random effect with non-zero direct-maternal genetic correlation. Direct heritability, maternal heritability and direct maternal correlation of the best fit model was 0.57, 0.16 and -0.78 respectively. The result indicates that problem of (co-)sampling variation occurs when attempting to partition additive genetic variance into direct and maternal components.

    The Hungarian sheep sector has become a one-market sector, almost the whole amount of slaughter lamb went to Italy, which increased its defenselessness. In addition to the sole Italian market showing a permanent demand for Hungarian lambs, it would worth to exploit possibilities in other European markets considering the seasonal differences in Italian prices. Such markets can be the Spanish and Greek for ”light” and the French, German and English markets for ”heavy” lambs. Both the Italian and Hungarian prices have three major periods: Easter, Ferragusto and Christmas. Due to the changes in the prices, the producers often suffer great losses, therefore, the temporal adaptation of production, market research, technological and development activities need to be improved. It is important that the living of Hungarian sheep breeders should not be dependent solely upon the Italian market, distribution of products should be ensured in other markets too, so that the safety of sales be increased and higher prices and higher income could be achieved. The European lamb prices are characterized by large seasonal fluctuation and the degree and timing of changes are different in the different countries. Study of the literature and the results obtained in my study on lamb sales called for an analysis and study of the possibilities of price forecasting. In my study, I performed a forecasting of lamb prices in Hungary and Italy for the period between 1996 and 2006 based on the data of the European Committee. Among the forecasting methods, seasonal decomposition and SARIMA models are the most precise, producers can achieve a better market position by using these in the practice.

    Because of the feeding technology innovation, accelerated transport and communication facilities breeds of high performance breeds replaced local autochone breeds worldwide. These latter species however have an important role in gene conservation. Hungarian cold-blooded horse breeding stock are lacking pedigree, the actual founder breed mares are not known. For this reason, it is an major priority defining the genetic backround of the existing flock, for that breeding could operate with purposeful using of origin maternal founders. In the present study 195 cold-blooded Hungarian mares tail and mane sample were analized. Our analysis was carried out between 15531–15752 base pairs in mithocrondial DNA D-loop region, which reported a total of 222 base pairs. Fourtyone polymorphic sites were determined, which resulted in 39 haplotypes (h=39). The average pairwise differences were k=6.825. High haplotype and nucleotide diversity values were observed (Hd=0.968±0.003, π=0.026±0.003). Based on the previously defined variable positions of haplotypes defined by Jansen et al (2002), we groupped our haplotypes into haplogroups. 23 percent of the studied population (45 mares) belonged to haplogroup F1. Nearly 97% of the analyzed population was classified into one of eight  haplogroups defined by Jansen.et al. (2002). This study gives genetic information nearly 25% of the Hungarian population. Another possibility would be patterning more mares or involving more genetic marker in the study which will assuming the possibility of a more comprehensive analysis.

    Our Faculty has been dealing with the cross-breeding of Hungarian speckled hen to maintain the breed since 1977. We keep two breeds of the Hungarian speckled hen, the bare-neck variant and the feathered-neck type on the pilot farm. Because of the spread of intensive poultry keeping the population of these breeds has become endangered. Beside the gene preservation, we endeavour to find the best way for the production-purpose
    utilisation of the speckled hen stock. We examined the egg production of these breeds.

  • Role of Sowing Time in Maize Production (Review)

    Many authors, both in Hungary and abroad, have reported on experiments carried out to determine the role of sowing time in maize, but the results are often contradictory. This is hardly surprising, since the maize plant exhibits enormous genetic variability and the hybrids created through selection and inbreeding may have very specific requirements as to sowing date. The year effect, too, often complicates the efforts of scientists to provide clear guidance to farmers on the optimal sowing date for each hybrid.

    Animal breeding increasingly lays claim to the theoretical and practical knowledge of applied ethology. The authors’ aim was to evaluate and compare the temperaments of Charolais (CH, n= 10) and Hungarian Grey (HG, n= 10) steers, and also to determine the correlation between their temperament scores and flight speed scores. Temperament was evaluated by the results of the scale test (assessing of behaviour in a 1-5 score system, while the animal is standing on a scale for 30 seconds) and flight speed test (minutes it takes the animal to move a set distance of 1.7 m when leaving the scale), on three occasions (1, 2, 3). Data management was done by SPSS.10 (ANOVA, Mann-Whitney-test, Spearman-correlation). Results of the scale test differed significantly between breeds at the third measurement (CH: 2,9 scores; HG: 1,4 scores; P<0,01) and when evaluating the three measurements together (CH: 2,0 scores; HG: 1,37 scores; P<0,05). Concerning of flight speed score, there were significant differences between breeds of steers at each measurement (1. measurement CH: 2,77 s; HG: 4,09 s; P<0,05; 2. measurement CH: 2,89 s; HG: 5,01 s; P<0,01; 3. measurement CH: 2,46 s; HG: 5,33 s; P<0,01) and overall (CH: 2,71 s; HG: 4,81 s; P<0,001). In the case of both breeds, evaluated by measurements and overall, a negative correlation was calculated between temperament score and flight speed score, but this was significant only in three cases: CH1 (n=10) r= -0,75; P<0,01; CH1+2+3 (n=30) r= -0,44; P<0,05; CH+HG1+2+3 (n=60) r= -0,33; P<0,01). Results indicate that Hungarian Grey steers are calmer than individuals of Charolais. Animals behaving calmer on the scale left the scale, more slowly. The authors propose the use of these temperament tests in Hungarian breeding practice, in order to select too temperament animals.
