Genetic diversity of the Hungarian draft horse assessed by mitochondrial DNA
29-32Views:253Hungarian draft is a horse breed with a recent mixed ancestry. It was developed in the 1920s by crossing local mares with draught horses imported from France and Belgium. To genetically characterize the breed and to set up the basis for a conservation programme, we have employed a molecular marker: a 256-bp D-loop mitochondrial DNA fragment. We analyzed 124 horses representing Hungarian draft horses to assess the maternal phylogeography of the breed. Sequence analysis of a 256-bp segment revealed a total of 34 haplotypes with thirty-four polymorphic sites. High haplotype and nucleotide diversity values (Hd=0.953±0.001; π=0.024±0.001) were detected. The average number of pairwise differences were k=5.998. This breed counts 800 mares today, and only survive due to breeding programmes, this way each haplotype frequency depends on the extent to which mares are involved into the breeding. The reduced number of surviving maternal lineages emphasizes the importance of establishing a conservation plan for this endangered breed. Due to the revealed 34 polymorphic sites we could presuppose twelve maternal linages, which could be a first step for making a breeding programme.

Analysis of the Station Test Results of the Hungarian Large White and Hungarian Landrace Populations Applying Survival Analysis
37-40Views:88Authors analysed the days of fattening in relation to the station test for Hungarian Large White and Hungarian Landrace pig populations using, survival analysis. Survival and hazard functions were calculated in both groups separately for castrates and females. The log-rank test was applied to determine the significance of the differences across the groups. Authors established that within the breeds the functions of the castrates and females were significantly different, namely the castrates reached final weight sooner or, in cases where final weight was not reached by a certain period, castrates reached this weight during the next time unit with a higher probability than the females.

Tourism-Based Analysis and Development Potentials in Hortobágy
272-278Views:107Tourism – especially ecotourism and health-tourism – could be one of the sectors which could make Hungary economically competitive after joining the European Union, by ensuring thousands of people employment possibilities, if they take advantage of local and regional opportunities. For this reason, it would be necessary to analyse the two types of tourism mentioned above, as well as to collect data and especially impressions concerning how these potentially lucrative sectors could best be structured and managed, as well as to predict their probable effects.
The most important objectives of my study are to introduce the values of Hortobágy, to analyse the present status of tourism in the Hortobágy National Park, and to make suggestions for increasing the numbers of tourists, by making Hortobágy more attractive.
As a resident of Debrecen, I visited the region several times and took part in programs at Hortobágy as well. I was always curious how the trip to the Hortobágy could be made more enjoyable.
My research was carried out with the help of questionnaires, which were made in three languages – Hungarian, English and German –. In August 2002, I approached foreign and Hungarian tourists in Hortobágy village, and asked them to fill them in. To evaluate the questionnaires, I used Microsoft Excel ’00. During the evaluation, I calculated distribution, arithmetic mean and deviation. Moreover, I obtained the level of significance.
My assumption that tourists visiting Hortobágy are “one-day” tourists, who are visiting the Hungarian Pusta because of an actual program, was supported by my research. I must emphasise that mostly passive tourism opportunities are offered in Hortobágy, where tourist are only external observers of the programs.
In order to change this situation, I suggested that visitors to Hortobágy can be encouraged to stay longer by offering them various programs, in which tourists are actively involved. My program recommendations include a craftsman’s house or tent, where the visitors can try to make typical folk instruments. Moreover, I made suggestions as to how to teach tourists to make Hungarian dishes. I also outlined several one-day program possibilities. Among the opportunities, I also mentioned the need to provide tourists possibilities to spend several days in a conventional Pusta life-style. To realise these things adequate infrastructure and information system should be developed. -
Remembrance of Bognár Sándor (1921-2011)
16-20Views:89Dr. Sándor Bognár was a distinguished cultivator of the horticultural entomology and a determining personality of the higher education of Hungarian crop protection. Training of the scientific and extension specialists of Hungarian agricultural entomology would have been unimaginable without him. He was researcher of the Plant Protection Institute, innovator of the crop protection training’s essential and organisational standard at the Horticultural College and Faculty, who sacrificed his life’s work for developing the crop protection and for the tracking of the history of Hungarian crop protection. He dealt with the Pimplinae (Ichneuminidae) at the very beginning of his carrier and later with the difficulties of soil dwelling pests (Elateridae) but he dedicated a lot of time to the pests of rice and the pest-assemblages of fruit trees and grape. It is important to mention his activity on the phytophagous mites, thus one can call him as one of the founders of the Hungarian agricultural acarology. One top of his educational work was the wonderful manual „Agricultural Entomology” written with László Huzián in 1974 and 1979. László Szalay-Marzsó said of this book that it was impossible to write a better one. He has been right. In spite of his advanced age he participated systematically in the conferences in Hungary and shared the knowledge gained during his long life, and the morals and patriotism got from his models and developed considerably.

Horn colour varieties of the Hungarian Grey cattle
83-87Views:121The Hungarian Grey Cattle breed is a ‘success-story’ of the national genetic conservation work. Traits of the breed have been subjects of several research projects, although many relationships remained unclear. Our present research results were meant to call attention to a less emphasized trait of the breed: the different horn colour varieties. Research work was carried out in the Hungarian Grey stock of the Hortobágy Non-profit Company for Nature Conservation and Gene Preservation. Ratio of the three main horn colour varieties (white, ‘cardy’, green) were determined in the observed female, male and steer stocks. Our results showed no significant differences (P<0,05) in the distribution of the horn colour varieties of the female and bull stocks, and of the female and steer stocks. We found that on the basis of the ratio of white colour, four sub-categories can be distinguished within the ‘cardy’ colour variety. Results of the statistical analysis (P<0,05) confirmed that the colour of the horn and the ratio of the black part on the horn tip are two different traits.

Comparative Evaluation of the Temperaments of Charolais and Hungarian Grey Steers
14-19Views:137Animal 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.

Survival Analysis of Hungarian Large White, Duroc and Pietrain Sows
31-36Views:273The aim of the present study was to perform lifetime performance analysis in three pig breeds; Hungarian Large White (n=295), Duroc (n=76) and Pietrain (n=91) on a commercial farm using analysis of survival sows. We took into consideration the age of sows at the time of their inclusion into breeding, their age at the time of culling, time spent in production, number of mating and parities, parity percentage, intervals between litters, number and mean of piglets born alive and born dead, number of raised piglet litters, number and mean of 21 days old piglets, the weight and mean of raised litter and raise percentage.
We carried out the analysis by SPSS 22.0. Single factor analysis of variants, Kaplan-Meier analysis and Cox PH model were used. The determination of the significance of risk rates differences was done by Wald chi square test.
Our results showed that the average culling age were 1056 (±33.52) days for the Hungarian Large White, 735 (±73.56) days for Duroc and 818 (±71.98) days for the Pietrain.
The log rank test of the survival analysis indicated a significant difference between the three tested genotypes (χ2=16.981, P<0.001), which means that the survival percentage of the individual breeds varied significantly from one another. In comparison with the Hungarian Large White genotype the Duroc genotype has a 1.6 times higher (P<0.001) culling risk while that of the genotype Pietrain was 1.36 times higher (P<0.001).
Our results can be used to compare the breeds kept under the same conditions and to compare the life span of one genotype under different farming conditions. Factors that increase survival and improve the profitability of pig farming can be determined by this method.

Carcass and the Meat Quality of Hungarian Lambs
65-71Views:123The author investigated 153 lambs of nine genotypes originating from breeding flocks, and 50 lambs originating from production flocks. The investigations were performed between 1995 and 1998. The authors discuss the evaluation of comformation and fat cover according to EUROP standards. The authors also investigate the proportion of valuable meat by genotype, and – out of the internal value indicators – the dry-matter, protein, fat, connective-tissue and hemin contents comparing the flavour, aroma, tenderness, and oven loss of the different genotypes.
The following findings should be highlighted:
♦ The Hungarian Merino breed should be improved, as – according to EUROP standards, more than 70% of these animals were rated as quality „R”.
♦ Hungarian fattening technology has to be preserved, as the lambs reach the desired slaughter weight within a short period of time, and without over-fattening.
♦ Readiness for slaughter, typical of each genotype, has to be defined, and slaughter at proper weight be achieved.
♦ It has to be re-evaluated whether the Hungarian Merino is the only breed which can be used in Hungary, as none of the investigations really proved the special characteristics and significance of this breed.
The author summarizes the findings of the investigation in five tables. -
The status of the Hungarian Merino sheep breed compared to the other merino breeds
151-156Views:285Merino and Merino-derived sheep breeds have been widely known and distributed across the world, both as purebred and admixed populations. They represent a diverse genetic resource which over time has been used as the basis for the development of new breeds. In spite of this, their gene-pool potential is still unexplored. The Merino sheep represent the most important sheep resource of the Hungarian husbandry. It has the largest amount of individuals between both of the stock and commercial flocks. But in Europe the Merino stocks went through a drastic reduction in number. Thus these breeds became endangered in several countries as well as in Hungary. In this study we would like to present the recent status of different Merino breeds of the world to ground our further phylogenetic research with the Hungarian Merino breed.

The Situation and Prospects of Hungarian Rural Development Preceding EU Accession
224-231Views:109Today’s Hungarian rural development is defined by the fact, that Hungary will be a member state of the European Union from May 1, 2003. Our accession means the end of a long period, and new rural development programs that are going to build on the basic of previously accepted EU standards and experience will highlight the immediate future.
From the Hungarian rural development programs I especially dealt with the SAPARD, AVOP and NVT, which in my opinion had and will have the greatest influence on the improvement of the Hungarian county. The AVOP and NVT are still under development (or just submitted to the EU), but their role in the future will be particularly essential, because these programs are going the act as the first programs in Hungary as a member state and a lot will depend on them in the improvement of the rural development. -
Evaluation of the relationship between main type traits and longevity in Hungarian Simmental cows
205-209Views:152The Hungarian Simmental cattle is a dual-purpose breed, having good milk and meat production characteristics. Simmental cows have some other important traits, for example, a longer productive life. The longevity or productive life is the time period between first calving and culling. The conformation contributes to productive life, reproduction, and milk production.
The aims of this study were to analyze the longevity of Hungarian Simmental dual-purpose cows, to evaluate the effects of the size of the herd, age at first calving, main type traits (frame, musculature, feet and legs, mammary system), and combination of main type traits (frame and musculature, feet and legs and mammary system).
Animal, age at first calving, herd*calving, musculature, the mammary system as well as the combination of mammary system and feet and legs were significant effects on longevity. The highest risk ratio was observed for cows first calved after 31 months. The risk of culling increased with increasing scores of musculature and decreasing scores of the mammary system. The highest risk ratio was estimated in category 11 (lower scores of mammary system with lower scores of feet and legs). In this case, the risk ratio was 36% higher than the reference group.

The analysing of value measuring features of Hungarian speckled hen
17-23Views:53Our College has been dealing with the crossbreeding of two Hungarian speckled hen breeds, the bare-neck and the featheredneck, to maintain the breeds since 1977. Apart from the gene preservation, we endeavour to find the best way for the production-purpose utilisation of the speckled hen stock. On the basis of our experiments the laying hens can be used in small-scale egg production. As for meat production, these pure-breds cannot compete with the various types of the colour-feathered hybrid constructions available in Hungary. On the basis of the results of the cross-breeding with cock-lines of various hybrid types for direct production purposes we can conclude that the Hungarian speckled hen is suitable as a mother line to produce meat-type chickens in alternative breeding systems.

Effects of diets with different fibre content on the performance of rabbit does and on parasitological infection
41-44Views:129The effect of two diets with different fibre contents was examined on rabbit does’ performance and parasitological infection. Diet P2 had 1% higher crude fibre, ADF and starch contents than that of diet P1. The performance of 12–12 does and litters per group were examined during two consecutive inseminations. In both dietary groups, according to a 49-day reproduction rhythm, the does were artificially inseminated 18 days after kindling. Most production traits were not affected by the diets (kindling rate, weight of does and their kits, feed intake, mortality; P>0.05). Significant differences were only found in litter sizes as the number of kits was lower in P1 diet fed group at all examined days of lactation. The significant “Diet x Reproduction cycle” interaction showed that the litter sizes of dietary groups did not differ at the first examined insemination, however at the subsequent reproduction cycle 6–8% lower litter sizes were counted in P1 fed does compared to group P2 (litter size at 4 day: 9.00 vs 9.58–9.92, P = 0.004; litter size at 11 day: 8.83 vs 9.58–9.92, P = 0.037 for diet P1 at the 2nd reproductive cycle compared to all the other cases, respectively). The two diets with different compositions did not affect most of the production results of the rabbit does and their kits, but the lower litter size of does consuming P1 diet at the second examined lactation suggests the adverse effect of P1 diet’s long-term use. From the collected manure samples not any parasites were detected which presents a very favourable picture of farm from the point of view of hygiene and animal health.

Examination of two artichoke cultivars under single year Hungarian climate conditions
112-115Views:82Based on the results of a previous experiment, we concluded that by choosing a suitable cultivar, it is possible to produce artichoke in a one-year cultivation system in Hungarian weather circumstances. The objective of the present experiment was to investigate the performance of two Californian artichoke cultivars (Green Globe, Imperial Star) under the local conditions. Experiments were conducted in 2002 and 2003, by using four
different sowing and two different planting dates (03.01. and 03.20. – planting 05.07.; 04.24. and 05.06. – planting 06.12.). For both cultivars, 100% of the plants initiated buds. In most of the cases, Imperial Star produced higher total and marketable yields than Green Globe did, while it formed bigger and more uniform buds. Our opinion is that the main reason for this result was that Imperial Star tolerated the dry and warm Hungarian summer much better. Irrespective of the variety by earlier sowing dates higher total yield was achieved. Based on our results, we found that under Hungarian circumstances, both cultivars could produce acceptable total yields. However, the weather circumstances of the given year influenced bud quality, and thus marketable yield, to a great extent. -
Dimensionality Expressed by Caseendings and Spatial Prepositions
7-15Views:92The purpose of this essay is to investigate some of the uses of English prepositions and Hungarian case endings employed to express spatial relations. The observation of invariant mistakes Hungarian native speakers learning English make initiated the investigation. The questions raised are: (a) where do the two systems match and where do mismatches lie, (b) how do language users perceive the world, and (c) do speakers observe spatial relations as two-dimensional or three-dimensional cognitive models? Do different languages see the same thing as either three-dimensional, or two-dimensional?
Abondolo (1988) gives an adequate morphological analysis of ten Hungarian case-endings (inessive, illative, elative, superessive, delative, sublative adessive, ablative, allative and terminative) used in spatial reference, which give a closed set in references made to factors, such as (1) location which can be broken down as interior vs. exterior location with the latter being further analysable as superficial and proximal, and (2) orientation which can be analysed as zero orientation (position), source and goal. In addition to those in this list, two other case endings (genetive/dative and locative) are also used for expressing spatial relations but the last is only a variant of the inessive and superessive case-endings and is only used with place-names. The set is closed in the sense that the same item is meant to refer to the same sort of spatial relation in every case. Language textbooks, c.f. Benkő (1972) seem to suggest a neat match between the above Hungarian case endings and their English prepositional counterparts, e.g. London-ban (inessive) = in London.
The picture, however, is far from being so clear-cut. The data, which were taken from various dictionaries and textbooks, show that the choices of both the prepositions and the case endings listed above depend on how the speaker considers factors (1) and (2) and that proximity is very important. Instead of a one-to-one match between the prepositions and the case endings, we rather find that the above case endings will match a dual, and in some cases a tripartite system of prepositions with the correspondences found in the two languages, which yield the following chart:
We suggest that languages may view or map the same physical entities in different ways, for example along surface vs. volume or goal vs. passage, etc.
Furthermore, we also find it possible that it is the language specific, inherent coding of the nominal phrase that decides – in many cases – upon the choice of prepositions and case endings. -
60th Anniversary of Hungarian Plant Protection Service
8-10Views:152The author briefly overview the history of the 60-year-old Hungarian Plant Protection Service, which has improved to a model by its ’golden age’ period with a well organized system and excellence of specialists on the chemistry period of Hungarian agriculture. The profound changes both in policy and economy resulted a serious structural changes which continue even nowadays. Meanwhile country borders have been opened than EU membership of Hungary have generated new challenges by appearance and spread of new pests.

How have thermal conditions changed in different phenological stages of apple (Malus domestica) in Northeastern Hungary?
137-142Views:71In temperate climates, most fruit trees need cold weather, low temperatures in winter, and a certain amount of heat during the growing season until harvest. One of the most apparent effects of climate change is the elevated temperature in all seasons of the year. In our study, the changes in thermal conditions have been calculated in Hungary's most significant growing region of apples using the Chill Unit for winters and the Growing Degree Days for summers. The meteorological data were obtained from the gridded dataset of the Hungarian Meteorological Service on a 10 km × 10 km grid, so the whole studied area is well-covered over the last 50 years. The results show that the trees are more exposed to early budding than a few decades ago. Furthermore, the accumulated heat amount in summers has increased drastically, which may increase the heat stress and lead to higher yield losses.

Evaluation of the current situation of the Hungarian higher education based on a few indexes
121-125Views:114Around the Millennium we experienced the worldwide development and the growing importance of the role of higher education played in the social and economic development. A few years later, however, a crisis appeared in the situation of higher education (Kadocsa, 2002). The Hungarian higher education system faces the perspective of serious changes in its fundamental principals – such as its main activities and the economical ways which are used to finance these activities – even if only parts of the new educational scheme come into effect. Considering this fundamental activity aspect of the issue, there are new challenges which make necessary to rethink the role and aim of higher education and to define the new tasks needed in connection with education, research and other services. Hungarian Education needs to be renewed and improved to avoid a complete
break away; therefore, future priorities and tasks in order to fulfill these priorities need to be defined (Vincze and Harsányi, 2011). The new conception seems to be based on restrictions of the budget as it is experienced recently: a new structure available for a smaller part of society with a restricted budget has been under development. However, not even a battle, let alone a war can be won without money, horses and arms. The recent financial restrictions as well as the parts of the Széll Kálmán plan concerning education prove that serious amounts of governmental funds is taken away from education. The international improvement tendencies contradict to basically all of these Hungarian priorities.
All in all, no reform or change – no matter how much wanted – can be achieved without appropriate funds. -
Genetic analysis of selected body measurements of Hungarian Sport Horse mares
40-43Views:187The authors made their analysis based on the body measurements of 3080 Hungarian Sport Horse mares listed in the Hungarian Sport Horse Studbook. Height at withers by stick, height at withers by tape, heart girth and cannon-bone circumference were measured in Hungarian Sport Horse mare performance tests.
Phenotypic correlations among height at the withers and heart girth and cannon-bone circumference varied within a range of 0.45-0.55. There was close genetic correlation (r=0.63-0.82) between the body measurement traits. Heritability values were moderate for height at withers by stick, height at withers by tape and heart girth (h2=0.31-0.49). There were high heritability values (h2=0.51) for cannon-bone circumference.
There were low phenotypic correlations between frame (as conformational trait) and height at the withers (measured by tape and stick) and heart girth. -
Önitatók konstrukciós és hidromechanikai vizsgálata
52-57Views:112Our research aimed to examine Hungarian automatic drinking system constructions and hydromechanics under laboratory conditions and in operation with special emphasison the small volume, valve types.
Considering that no Hungarian standard of automatic drinking system examination and qualification exists, on the basis of technical literature, the new examination method of automatic drinking systems has been elaborated.
For laboratory measurements, a universal measuring bench was assembled which is applicable to the hydromechanic testing of all automatic drinking systems (cattle, sheep, pig).
Summary of the laboratory measurements:
Upon comparison of the flow capacity of the valves, in the case of same opening values (h/dn), the rubber spring valve of SZI type automatic fountain has the highest flow capacity, although in the case of 100 kPa pressure even this type has only 15-16 l/min value which hardly surpasses the lower limit of the desired 15-25 l/min range.
The loss coefficients of the valves, on investigating in the range 100-200 kPa, showed the lowest value (2,2-5,8) with the steel spring self drinking device.
Summary of the operational investigations:
In the long term operational investigations, the rubber stripped valve and the rubber spring automatic fountains had the most favourable operational reliability values: K4=0,98 and K4=0,94, respectively.
From the aspect of animal operation of the valves, all the Hungarian types are frontal operated, thus such system automatic valve drinking devices can be used only in long and moderately long stands, directed toward the animal.
On the basis of hydromechanical and construction examinations of the Hungarian tied cattle production technology the construction modification of the rubber spring valve of SZI type automatic drinking fountain, which is the most frequantly used in this country, was carried out. Due to design modifications the valve parameters improved significantly.
The goals of the accomplished valve modification were
ζ'sz – loss coefficient to be reduced
q – flow capacity to be increased -
Horn and coat color varieties of the Hungarian grey cattle
44-48Views:123Due to the intensification of agricultural production, genetic diversity has been reduced to a large extent. Presently, in the period of worldwide genetic conservation, we try to preserve as much of the gene pool of our valuable indigenous domestic animal breeds as we can. Therefore, traits that have no economic value at the moment should also be conserved. The different horn and coat colour varieties of Hungarian Grey Cattle are such valuable traits. Research has been done on the largest Hungarian Grey Cattle stock, at the Hortobágy Kht. Rates of the different horn and coat colour varieties were determined and relationships were analyzed between the above mentioned qualitative traits

The applicability of 10 ml cryotubes for sperm cryopreservation in a Hungarian carp landrace (Cyprinus carpio carpio morpha accuminatus)
93-97Views:245In our study, the comparison of 5 ml straw and 10 ml cryotube during sperm cryopreservation in a Hungarian carp landrace (Cyprinus carpio carpio morpha accuminatus) was carried out. Three different dilution ratios (1:1, 1:4 and 1:9) were also tested using the cryotube. A significantly higher pMOT was recorded using the cryotube in comparison with the straw. VCL and STR were similar in both groups. Cryopreservation had a negative effect on pMOT and VCl using the cryotube and also the straw where, STR was not reduced significantly. An increasing tendency was observed using higher dilution of sperm during cryopreservation; however, significant difference was not recorded between the three groups. VCL and STR were similar in all groups. Cryotube was applicable for the sperm cryopreservation of the Hungarian carp landrace. However, the standardization for the freezing method specified for this volume is recommended. The different dilution ratios needed be tested also during fertilization.

Changes of Longissimus Muscle Area and Rump Fat Thickness in Hungarian Simmental Fattening Bulls Measured Using Real-Time Ultrasound Equipment
11-15Views:99The aim of the authors was to evaluate changes in the longissimus muscle area (LMA) and rump fat thickness (P8) based on real-time ultrasound scanning in the Hungarian Simmental cattle breed. Ultrasonic measurements were carried out on the same 11 Hungarian Simmental fattening bulls by Falco 100 (Pie Medical) equipment (I.: age: 357±23.47 days, live weight: 475.55±51.40 kg; II.: age: 418±23.47 days, live weight: 555.10±54.11 kg) on two occasions. Animals were kept in small groups, on deep litter, and fed on silage and concentrate. LMA and P8 were measured on the scans, between the 12th and 13th ribs by manual outlining. Results for the investigated traits during the examinations were as follows: P8: I.: 0.373±0.154 cm, II.: 0.624±0.161 cm; LMA: I.: 65.72±5.89 cm2, II.: 71.74±8.94 cm2. During the fattening period, P8 increased significantly (I-II.: t=3.73, P<0.001). A significant positive correlation was calculated between results of measurements I. and II. in the case of LMA (r=0.71, P<0.05). Results imply the possibility of selling bulls with smaller LMA earlier, at lower body weight. Application of ultrasonic measurements in fattening technology could generate a more quality-related pricing system.

Values of Hungarian pigeon breeding
9-14Views:203Pigeon breeding has a history dating back several centuries in Hungary. It has internationally renowned and accepted results. Our aim was to estimate the range of values related to Hungarian pigeon breeding and draw attention to the importance of their conservation. We studied the biological values of native breeds and the appearance of pigeon breeding within the Hungarian culture. These include the use of the symbol, the relating beliefs and customs, language, gastronomy, architecture and object values, as well as the community-building effect. Based on our results we can say that this topic is worthy of further research.

Local strategical tasks in the Hungarian fruit production with respect to the global economic and climatic changes
39-34Views:131After identifying the problems, we have determined the local tasks which Hungarian fruit growing has to accomplish to remain competitive despite global market pressures and global climate change.
Fruit growing in the Great Plain is of determining importance in Hungary as 75% of fruit originates from the Great Plain. Therefore, the maintenance of the competitiveness of fruit growing on the Great Plain is an important economic interest which is a difficult task to resolve, because the global economic pressure against local resources and climate change affect the fruit growers sensitively.
In Hungarian fruit production, it is necessary to select/develop with great care the appropriate location, training system and methods of emergency technology which have to be harmonised.
