Economic and management considerations in two dairy systems grazed and arable crops based
47-52Views:57On the Hungarian dairy farms grazing is not a common practice presently. What are the reasons for this situation? Necessary conditions are not available for grazing, or the technical considerations about grazing are not favourable in practice. These questions were investigated on two dairy farms with methods of farm visits and technical interviews. Farm 1 still has grazing, Farm 2 used to graze its animals, presently it does not graze its animals, but it plans to establish pasture for grazing. Summarizing results of the investigations:
- Non of the farm has got enough pasture/land area to meet the requirements of grazing. This situation fits to the national situation known from literature and statistics.
- The time of substantial herbage allowance is relatively short, it is maximum 2 month in the season.
- The nutritive value of grass decreases sharply in Spring. It is the reason why only animals requiring less intensive feeding can be grazed (first of all dry cows, than heifers and perhaps low yield cows).
- Grazing can result in remarkable savings regarding inputs and costs.
- Grazing does not need specific labour, present staff of the farms. Can manage grazing at the necessary technical level.
- Asset security of outdoor animals we not considered as a real obstacle against grazing on the farms. This situation is different of that reported about the national situation. -
Fajösszetétel és diverzitás változás kiskunsági száraz és nedves fekvésű legelőkön
15-30Views:120Investigations were carried out in wet – next to Tatárszentgyörgy, and dry grass pasture – next to Bugac, both located in Kiskunság, in the central region of Carpathian Basin. Recordings were taken every June of 2007, 2008, 2009 and 2010 from Tatárszentgyörgy – where cattle were grazed, and 1997, 2005 and 2010 from Bugac, where cattle and sheep were grazed. Coenological recordings were taken in three zones. The first zone ("A" zone) located 0-50 m near the stable, second zone ("B" zone) located 50-150 m from the stable, while the third zone ("C" zone) located farther then 150m from the stable. Analyses of ecological and environmental factors were based on Borhidi’s relative ecological indicators. Life form analyses were performed by Pignatti life form types. For statistical evaluation, R software was applied. Shannon diversity. Based on our results for both dry and wet grasslands, quadrates of "A" zone were well isolated from the rest of the zones. Overgrazing, which involves considerable trampling, vanishes differences among vegetations, thereby promotes weed and disturbance tolerant rich vegetation. The lowest species number and diversity could be found here. Recordings for "B" and "C" zones separated from recordings of "A" zone, furthermore, quadrates of wet and dry grasslands formed separate groups. From recordings of "B" and "C", zone perennial grass species (H caesp) and the emerging perennial (H wrap) species multiplied and these species were the indicators of grazing. The greatest lifeform richment were presented among "B" zone recordings. The amount of intensive grazing indicator species, such as creeping perennials (Hrep) was significant in "B" zone recordings of Tatárszentgyörgy. Grazing stabilised the local vegetation, but increased the ratio of disturbance tolerant species, which was confirmed by conservation evaluation. This is due to the conversion of grassland types, the transition from free grazing to switch grazing, which resulted in an intensive involvement of the more distant "C" zone as well. "A" zones fully converted; they changed into fully reliefs. Further located sample area vegetations were not homogenised by grazing and even helped the preservation of characteristic species. In the aspect of environmental protection, vigorous grazing led to a more valuable vegetation in "B" zone in an arid grassland (Bugac). According to the sample area, wet grasslands from the sandy areas of Kiskunság, preserve nature protection values and grass composition better moving away from stables, due to less grazing pressure. Drier backgrounds tolerate stronger grazing pressure (Bugac), while in case of wetter areas (Tatárszentgyörgy) – considering sustainability – grazing should be carried out with caution.

Investigations on grassland and nature reservation effect of horse grazing in Tapolca and Káli Basins (2008)
65-72Views:64Examined areas can be found in the Tapolca and Káli Basins near Köveskál and Nemesgulács. Near Köveskál 2 horses were grazed on a 1 ha grassland, which was on a degraded association of Cynodonti-Poëtum angustifoliae. Control area was found close to the grazed grassland where Salvinio-Festucetum rupicolae association was found. The grassland was grazed formerly by sheep. Near Nemesgulács 4 horses were grazed on a 6 ha pasture under free range grazing system (0.7 horse/ha) on a Cynodonti- Poëtum angustifoliae grassland that is situated on a slope. Sample areas were selected the upper (UTS) and lower (LTS) third of the slope. This area formerly was as vineyard. 5-5 replicates of 2 by 2 m coenological quadrates were monitored on each sample area. Sward composition was investigated by Braun-Blanquet method (1964) in the grazing season of 2008. Ground cover (D) species composition and species number (n) were evaluated as analytical parameters. Relative nitrogen demand (NB), social behavior types (SBT) (Borhidi, 1995) and nature conservation value categories (TVK) (Simon, 2000) were also analyzed. At the LTS of the slope near Nemesgulács we could find species with bigger proportions indicating nutrient rich production sites and N indicating Artemisia vulgaris, characteristic species of manured sites appeared, too. At the UTS their proportion was smaller. The reason for this difference is the nutrient run off the slope and its accumulation at the LTS. The reason for the low nutritive value of the grassland are the lack of valuable Poaceae and pulses species and the low total cover. Valuable plant species were grazed out of the sward and negative effects of trampling could have been observed. Concerning the selective grazing preference of horses, the species composition of this area is not suitable for horse grazing. Instead of horses the area could be more suitable for sheep grazing. Pasture near Köveskál had extremely high proportion of species requiring nutrient rich conditions that can be probably due to frequent depositions of excreta and urine by grazing horses. Both control and pasture areas has the highest (approx. 35% absolute) cover of natural species with disturbance tolerance. The biggest difference in nature conservation value categories was the decrease of association composing species on the pasture. This was mainly caused by the grazing out of Poa angustifolia that was the most valuable species in the association. Overgrazing and grazing method applied caused very low plant cover on the grazed pasture.

The role of sheep grazing in nature reservation
95-100Views:54Economic and social changes in the last two decades reduced the grazing animal systems more or less to the nature reservation areas. The main objective of these grazing systems on these areas is the preservation of natural treasures herited from the past. Beside that, grazing systems have social (employment) and economic (production) roles as well in some areas of the country. In this paper connections between sheep grazing and the maintenance of different grassland associations of Hungary are investigated from the point of nature reservation friendly farming systems. In general sheep grazing have more positive effects on nature reservation grasslands than its negative effects. It is not difficult to identify the negative effects and to apply proper practical methods avoiding or reducing these effects. Sheep grazing is a proper tool to handle the fragmentation of some of the national grassland areas so it must be kept on as a critical method in the natura friendly farming practices.

Results of grazing preference investigations incounty and abroad
21-25Views:32Many kinds of animals were already studied on which composition of pasture they reside most of their time, respectively which constituents of pasture they eat more pleasantly. In Hungary there have not been done any researches on the red deer grazing habitude in farming conditions yet. The target of this study was to examine which species of the plants are the most preferred by the red deer under the conditions of Bőszénfa’s area. The pasture planting was in 2005. At the choice of the species’ planted the climate conditions and relief of this area were taken into consideration. Seven kinds of pastures or pasture mixtures were planted in two repetitions. Because of the unfavourable weather conditions the development of planted pasture was slower than expected, in this manner the preferences examination was put off to 2007. The preference study of plots planted with different pasture constituents was carried out by grazing of 48 hinds. During the grazing season the time of residence of the grazing hinds on every single plot was measured 14 times by five hours’ observations. The observations could be carried out from April to the end of June because of the pasture plots were totally burnt out due to the lack of the moisture. Our measurements were completed with field reviews. During the reviews the most consumed species of plants were noted. The statistical analysis of the observed period was carried out in monthly dividing too. In April the gramineaes and the white clover (Trifolium repens L) were grazed in the same proportion (P<0.001) by the hinds, but they did not prefere the giant agrostis (Agrostis gigantea Roth) and the bunias orientalis (Bunias orientalis). In May the dears grazed the white clover the most intensively, and the gramineas on the right hand side, the giant agrostis and the bunias orientalis were eaten the least. In June the hinds spent the most time by grazing on the white clover, the graminneaes were mediumly grazed, the giant agrostis and the bunias orientalis were grazed almost not at all. Summarized the red deers spent the most of their grazing time on the white clover, while they grazed on the giant agrostis and on the bunias orientalis for the least time.

Shall we graze?
36-39Views:46Since the end of the 18th century, since 1780, this question has been raised more and more frequently. At that time, an acknowledged authority wrote in his book that we should not graze and the number of those against grazing has been increasing since then. Nowadays many scientific popular and scientific articles are published against grazing.
This short summary examines the question from the aspect of the users and describes those obvious reasons which cannot be neglected. The herds of grazing animals were welcomed by the cities of western countries from Strasbourg to Venice because of their excellent meat quality. This export gave 70% of the country’s revenue.
For the above reasons, the answer to the question of the title is definitely yes!! -
Overutilization of Pastures by Livestock
29-35Views:237Soil degradation caused by overgrazing is a worldwide problem. The degradation of an overutilized area occurs mainly where animals prefer to spend extra time because of the attractants that are around gateways, water sources, along fences or farm buildings. High grazing pressure decreases plant density which results in changes of the botanical composition of a pasture. The effect that grazing has on a plant depends on the timing, frequency and intensity of grazing and its opportunity to regrow. Overgrazing adversely effects soil properties, which results in reduced infiltration, accelerated runoff and soil erosion. Evidence has been corroborated with high bulk density values, high dry mechanical resistance and low structural stability. The degradation of the landscape may be a short-term phenomenon and recovery is possible after grazing pressures have been greatly reduced. Management practices have been used successfully to improve grazing distribution. These practices include water development, placement of salt and supplements, fertilizer application, fencing, burning, and the planting of special forages which can be used to enhance grazing by livestock in underutilized areas.
The authors carried out their grazing experiment on the Hortobágy. The effects of overutilization by livestock on soil properties and vegetation on certain areas of grassland are presented in this paper. -
Botanical and natural conservation comparison of seminatural and man-made grasslands in Paskom near Csakvar
3-14Views:262During the survey, the vegetation, botanical composition and grassland management values of a grassland were studied. The study site was originally a pasture, then was transformed into an arable land and finally back to pasture. The 160-ha-sized area is called „Szűzföld” and is located in the Zámoly Basin, West Hungary. In 1998, grazing of Hungarian grey cattle has begun on the grassland. The changes in the vegetation were followed from 1998, making records in every 6th year (1998, 2015, 2021). 6 coenological records were made in each type of grasslands, by recording the list of the occurring taxa and their cover values. During the survey the main questions were the following: considering nature conservation, coenology and grassland management, in which direction does the vegetation evolve with the grazing? Was the grazing with Hungarian grey cattle successful?
Based on the results, the grasslands became much more mosaic-like; drier and wetter vegetation patches could be separated (2015, 2021). As the grazing continued, species richness and diversity increased, especially in the wet areas.
The number and the cover of economically important grass taxa and legumes have increased. The following taxa became dominant: Festuca pseudovina in the drier parts, Agrostis tenuis and A. stolonifera in the wet ones. Based on the life form system of Pignatti, the area is not overgrazed, as rosette and reptant taxa did not became dominant. Based on nature conservation values, cover of the taxa of natural grasslands increased.
During the grazing, the meadow was universally covered mainly by weeds in 1998, and became much more valuable by 23 years later by means of nature conversation and grassland management. Moreover, this state has been stabilized according to the diversity values.
Based on the results, the grazing with Hungarian grey cattle was successful by both nature conservational and economical means. -
Monthly changes in the production and content values of wet Hungarian gray cattle pasture and the relationship with species richness
19-28Views:75Grassland management tests were performed on different grazing loaded gray cattle pasture and hayland areas 4 times (April, May, June, September) during the grazing season in Tapolca-basin. 5-5 pieces of 2×2 m samples were examined on each sample area, prepared according to the Braun-Blanquet method (1964) in April, May, June and September and with this, we also measured the amount of biomass and its content.
Based on results additional pasture had the largest gazing livestock carrying capacity but it had the weakest feed quality as well. During grazing season due to ongoing livestock grazing, species composition has changed the most in case of pasture and the number of species was the greatest here as well. Proportion of grasses declined in parallel with the amount of legumes, which grown till late summer.
Nutrient content of pasture forage was the most appropriate because of high crude protein and less crude fiber content. Grazing for 34 days/year was not enough in case of additional pasture where Festuca arundinacea had the largest coverage. This is reflected in low number of species richness and small nutritional values of sample areas. For sedge rich low-lying areas mowing utilization is the most effective. -
Comparative investigations of biomass composition in differently managed grasslands of the Balaton Uplands National Park, Hungary
49-56.Views:45Phytosociological and biomass samples were collected in two territories of the Balaton Uplands National Park (Hungary) dominated by grassland habitats. Samples in the Tihany Peninsula had been taken in a pasture of Hungarian Grey Cattle. Studies were broadened to four areas of the Tapolcai Basin, Badacsonytördemic (undergrazed and overgrazed pastures, hayfield, control area). The areas were suitable for following up the changes of vegetation and production in every grazing season of a year. We evaluated the changes of species composition and ground cover, the measure of possible regeneration or degradation, and the changes of these factors from the viewpoint of feeding value. Covering rates of the grassland associations have doubled and species composition has improved in the Tihany Peninsula, however, forage value has not increased, due to the change in land use in favour of the natural area that is converting into grazing field. In case of the Taplocai Basin, low number of species (20 to 30) was detected in the undergrazed pasture and the control area. About one month per year grazing time in the undergrazed area was not enough to achieve a better state for species diversity, and the amount of forage remained high. The overgrazed pasture carries a low forage value and contains a high number of weed species, despite the spectacularly high total number of plant species (38 to 39), consequently, grazing pressure has to be decreased. Although the number of species is lower in the hayfield (26 to 28), species composition and ability for forage supply is much better, showing that the proper management of the area is taken here.

Comparison of vegetation of Hungarian Grey Cattle and Domestic water buffalo pastures in a sample area of the Danube-Tisza Interfluve
15-31Views:54We made a coenological study on the Kelemen-szék in the Kiskunság National Park. The coenological studies were carried out twice, in 2014 and 2015. During these two surveys, we examined in total 90 quadrats of mixed grazed and fenced control areas by domestic water buffalo and Hungarian Grey Cattle. Due to the size and heterogeneity of the studied area, we intended to investigate small homogeneous areas and respective control areas. Coenological surveys were done on lower and higher lying pastures, saline soil areas and loess areas.
The studied areas were assessed based on the Borhidi relative plant ecological indicators NB (relative nitrogen values) and WB (relative groundwater and soil moisture indicator values). The distribution of nature conservation value categories (TVK) and social behavior types (SzMT) were used to assess the areas. Cluster analysis and detrended correspondence analysis (DCA) were used to evaluate the data.
The data were assessed based on both habitat condition in terms of naturalness condition. On the other hand, relative ecological indicators of the occurred species. Our objectives were to provide a detailed description of the vegetation composition of the study areas, to assess the changes in grassland composition and their conservation impacts as a result of grazing and its abandonment, to assess the impact of grazing on the occurrence of protected species and weed species, and to assess grazing as a conservation habitat management practice.
The examination of the species composition showed that the loess and saline soil areas grazed by domestic water buffalos and Hungarian Grey Cattle provided a better composition of grassland in terms of natural condition compared to the control areas. In the dense and tall Puccinellia swards vegetation type, grazing requires more attention, because it is more vulnerable to grazing, has fewer species and is more damageable.

Természetvédelmi és gyepgazdálkodási vizsgálatok a Dinnyési-Fertő gyepeiben
31-38Views:74The present study includes coenological results of the effects of grazing with Hungarian grey cattle in saline grasslands in Dinnyési Fertő Nature Conservation Area. This kind of managment is favourable for the grazing and trampling tolerant grass species and decreases the proportion of the dicots.The classification of species based on the social behaviour types of Borhidi shows the spreading of the ruderal competitor species, mainly Cynodon dactylon with the progress of the grazing season. Grazing prefential from a bird conservation aspect increases the number of species, however, it modifies the mass relations between species in a negative way.

Comparison of vegetation of Hungarian Grey Cattle and Hungarian water buffalo pastures in a sample area of the Danube-Tisza Interfluve
59-64Views:51In the present study, we aimed to investigate the coenology of the Kelemen-szék in the Kiskunság National Park. The coenological studies were carried out twice. We compared areas with different vegetation types. During these two surveys, we examined in total 90 quadrats of mixed grazed and fenced control areas. Ones were grazed by Hungarian domestic buffalo and Hungarian grey cattle and others were no grazed. Based on these surveys, it is possible to conclude about spatial and temporal changes in vegetation as a result of livestock husbandry in the area. Due to the size and heterogeneity of the studied area, we intended to investigate small homogeneous areas and respective control areas. Coenological surveys were done on lower and higher lying pastures, saline soil areas and loess areas.
In the study plots, grazing led to stability in the species composition of loess grassland and saline grassland, so that they also satisfy the requirements moof nature conservation. The dominant and character species of the associations, and the typical species of the genus Festuca have a significant cover value. The dense and tall Puccinellia swards require more attention, because they are more vulnerable against grazing. Grazing and extensive livestock husbandry, which can be applied in the future, is a suitable method for the management of lowland areas. In order to conserve the associations, preservation of grazing is necessary. To provide amount of biomass of areas, the grazing has a significant role. The conservation of native loess grasslands, even in the form of fragments, plays an outstanding function. Hence, based on the initial surveys, the combination of Hungarian grey cattle and water buffalo is beneficial in terms of nature conservation.

Felhagyott jószágállások növényzetének vizsgálata a Hortobágyi Nemzeti Parkban
21-27Views:39Extensive grazing, especially sheep grazing is the most important land use type in alkali grasslands of the Hortobágy National Park. Extensive grazing systems rely on some basic infrastructure, such as sheep corrals, wells and stables. Sheep corrals are characterised by intensive land use: grazing, trampling and manuring is concentrated in these places, thus the vegetation of actively used corrals is markedly different from the vegetation of extensively grazed grasslands. I studied the vegetation composition of eight-year-old and sixty-year-old abandoned sheep corrals and extensively grazed pastures in Hortobágy National Park. I recorded the percentage cover of vascular plants in twenty 2×2-m plots. The cluster analysis showed that the vegetation of abandoned sheep corrals was different from pastures. I found that the cover of annual and biennial species was higher, while the cover of perennials was lower in abandoned sheep corrals compared to the pastures. Due to the intensive land use in the past, the proportion of nitrophilous species was higher in sheep corrals, than in the pastures. The cover of competitors was lower, while the cover of disturbance tolerants, weeds and ruderal competitors was higher in sheep corrals than in the pastures. The results suggest that even grassland regeneration started in the sheep corrals and several target species established in the vegetation, the recovery of grasslands similar to extensively grazed pastures takes longer time.

Animal welfare issues in grazing
31-39Views:46From the very beginning cattle was linked to the pastures and countryside. Development of the animal production and limited land resources pushed producers to keep cattle in places where they would be collected together. That solution helps to run breeding and husbandry procedures more efficiently. However, even with the support of genetics and management, modern agriculture faces problems related to indoor system. There is a dilemma among farmers to keep animals indoor or outdoor. In the following material attempt will be taken to analyse factors related to grazing and cattle welfare issues. This work will not only focus on Hungarian or European agriculture issues. Experiences and animal policies related to grazing cattle from different countries and regions of the world were also collected. Actions taken in one part of the world might be not applicable in another. However, it is still interesting to see how agricultural production affects nature resources and communities. There is the same background off all stories related to grazing cattle - sustainable development and particular lobby behind. Whether there is a farmer, holding, enterprise or animal welfare organisation. There is only a question if this is going to be more economical or ethical approach.

Effects of grazing as anthropogenic environmental factor of natural grasslands in the Hungarian Great Plain, near Bugac
39-41Views:40The coenological quadrats were made in 1997, 2005, 2010 and 2021 in a sandy grassland which is used as cattle pasture. The quadrats can be sort in three groups. The first group of quadrats was made close to the cattle pen (Zone A: 0-50 m). The second group was made farther (Zone B: 50-150), where the grazing is not so intensive. The third group contains the quadrats which were made farther than 150m (Zone C). The animals use this area rarely, therefor this part of the pasture is undergrazed (Penksza et al., 2010a). The coenological survey was carried out with 2×2 meter squares, recording the cover value. The species names follow the nomenclature of Király (2009) and Engloner et al. (2001).
The rate of species which indicate degradation is the highest near to the cattle pen (0-50m). But farther than 50m the rate of species which indicates naturalness is higher. Lower nature conservation value can be observed near to the cattle pen. In this area weeds and degradation tolerant species can be found in the highest amount. Their ratio grew in the second zone (50-150m) too in the past few years, but the species which compose the natural vegetation also survived, so the species composition is able for regeneration. With the decreasing of grazing intensity the sample area could meet the requirements of nature conservation.
Data evaluation was made with considering naturalness state in case of habitats; and on the other hand, according to relative ecological factors of occurring species. A significant change in species composition could be detected. Particularly, deterioration of areas could be experienced. These negative processes are extremely heavy inside and near the animal husbandry farm. Even aggressive, invasive plant species occurred. Among dominant grass species, dominance relations and covering rate of disturbance tolerant Cynodon dactylon and Lolium perenne species have increased, caused partly by overgrazing and trampling as well. A new species, Poa humilis, appeared in the zone “A” in 2020, which is a degradation indicator species and tolerates overgrazing and trampling (Penksza and Böcker, 1999/200; Penksza, 2009). Farther from the farm, rate of degradation showed by vegetation has decreased compared to the areas closer to the farm, however, it has increased even on the farther area between the two time periods. During the preparation of management plans for the grasslands, these data should be considered at a higher rate in favor of preserving natural values,

Botanical and grassland investigations in a pasture grazed by Hungarian grey catte in Badacsonytördemic in 2008
73-78Views:32Sample areas can be found in the Tapolcai Basins. Phytosociological samples were collected: 32 ha grassland stand with low intensity grazing (under-grazed pasture), 38 ha overgrazed pasture, 34 ha meadow (hayfield) and the stand where animals drank. The areas were suitable for following up the changes of vegetation and production during the grazing season of the year. 5 replicates of 2×2 m phytosociological samples plots were examined on each grasslands according to the Braun- Blanquet method (1964) in April, May, June, August and September 2008. 118 Hungarian Grey Cattle were grazed on the pastures. 14 species were common in each saple areas, wich are dominant species of natural grassland associations (Agrostis stolonifera, Festuca arundinacea, Deschampsia aespitose) in the region. The overgrazed pasture had only low nutritive value and contained high number of weed species. About one month per year grazing time in the undergrazed area was not enough to achieve a better state of species diversity, although the forage production of the area remained high. The number of species and the 32 ha grassland was high (58) weeds was due to the high number of weeds, however the nutritive value of this grassland was poor. The species number of the hayfield was lower (31) than and grassland, however species composition was better and the nutritive was higher. It seemed that management was suitable and the hayfield.

Domestic water buffalo (Bubalus bubalis) grazing as a habitat management and application option against invasive species
47-53Views:85In nature conservation, the aggressive expansion of invasive plant species and the preservation of valuable grasslands are a global problem. Based on this, the following question can be formulated: which animal species and breeds are suitable for habitat management? Is the water buffalo suitable for lawn care and to what extent? With the overview work, we review the results so far, highlighting domestic areas where we already have preliminary results and where previous data have already been produced. Based on this, the invasive Solidago was completely suppressed in the marshes of the Zámolyi basin, the pasture was completely transformed, and the dominant species became Sesleria uliginosa. Also in the area of the Zámolyi basin, there were significant floristic and physiognomic differences in the vegetation. You may find that buffalo grazing is a suitable habitat management method in both dry grassland and wet grassland. Therefore, in addition to being effective in the control of Solidago gigantea, grazing with buffaloes is successful both in terms of nature conservation and grassland vegetation from an economic point of view. The first stage of the long-term planned work is an overview of the work on the water buffalo. The research is supported by the creation of Innovation operational groups and the investment necessary for the implementation of the innovative project. call for tenders (VP3-16.1.1-4.1.5-4.2.1-4.2.2-8.1.1-8.2.1-8.3.1-8.5.1-8.5.2-8.6.1-17) and the Innovation and the New National Excellence Program of the Ministry of Technology code number ÚNKP-22-3-I-MATE/2 was supported by the grant funded by the National Research, Development and Innovation Fund and grant AKGF-119-1-202.

Recent issues of animal welfare and health in sheep grazing
45-49Views:58This review paper presents an outlook on animal welfare measures and two potential sheep deceases with the objectives to assist sheep grazing farms in the region. Animal protection and welfare have been controlled by legal acts since 1978. Optimal animal keeping technologies, conditions of pain-free transport and slaughtering are described in specific acts and regulations, deviations from these conditions are fined. In the last decade special attention was paid to a couple of recent sheep deceases internationally: blue-tongue and scrapie. The scrapie, is not a recently recognized decease, but veterinary science turned towards it again as a consequence caused by the problem a cattle BSE decease. Fortunately, Hungary has been free from the scrapie for nearly 50 years. The bluetongue decease was taken to Hungary in 2008 from Western Europe with some imported animals. Strict animal health measures however made it possible for our country to get rid of this decease by now.

Clarifying the effect of season on the early crop development of unconditionally grazed sheep
17-22Views:23The feasibility of first grazing of extensive sheep pastures was investigated by monitoring the height of grassland in the spring of 2022 and 2023 at the Karcag Research Institute, focusing on the effect of vintage in this manuscript. For 6 grassland plots with different parameters, potentially suitable for early spring sheep grazing, in a meadow on solonyec soil with no level of inputs due to environmental subsidies, we refined soil temperature, soil moisture and height of grassland vegetation at the same time of year. For both years, it was concluded that it is justified to start grazing sheep on the fallow grassland and the pasture forest.

On either side of the electric fence: A botanical study of the autumnal aspect of the drained lake bed of a domestic water buffalo pasture in the Zamoly Basin
9-14Views:61Our studies were carried out in a water buffalo pasture of the Zámolyi basin, in the area of the Csíkvarsai meadow, in the bed of a former lake, which was drained in 2022, then dried up by autumn and it was grazed by domestic water buffalo. The grazed area was surrounded by an electric fence. The vegetation of this part of the area and part of the outside was surveyed on 19 of November. We took 3-3 coenological surveys in both separated areas. Based on the results, there were significant floristic and physiognomic differences in the vegetation. Among the clover species, species with ground-running stems (Trifolium repens and T. fragiferum) were dominant in the grazed area, but in the ungrazed area, there was a coherent plant population of 30-40 cm high, densely located alsike clover (Trifolium hybridum) in the lake bed. In addition, the occurrence of swamp pricklegrass (Crypsis schoenoides) was a floristic new discovery.
Due to the loss of water coverage, several Trifolium species have become abundant in the area, which is a result of the germination properties of the species. The thick seed coats were cracked by the loss of the effect of the water coverage on temperature equalisation, and germination could have begun, resulting in a dominant species in the area. During the present study, we have seen a very impressive result of the analysis of the vegetation of the lake bed in autumn aspect in the Zámolyi Basin, which is the result of the impact of water buffalo grazing. The number of species was more significant in the grazed area. Moreover, floristic rarities have been found and as an indicator of grazing, species of different life form types were dominant within the same genus. -
Changes in forage values of differently managed grasslands in the Trans-Danubian Mountain Range, Hungary
26-33Views:74In this study a comparative relevé was conducted in the Transdanubian Central Mountains (Tihany Peninsula, Bakony, Keszthely hills). We evaluated the changes of species composition and ground cover, the measure of possible regeneration or degradation, and we evaluated the changes of these factors in the point of view of feeding value. We surveyed that how extent the main grasses and the papilionaceae appeared or disappeared, how changed the proportion of those species which can tolerate overgrazing, and what is the composition of the weeds on grazed and ungrazed areas. Accordig to results, the grasslands under survey have unfavourable species composition due to the bad management practices and insufficient technological conditions. The distribution of the nature protection value categories of the plant association’s species varies with the associations. The period under survey the closed grassland association near Lake Belső turned more valuable, where the meadow was converted into pasturing lands for Hungarian Grey Cows by changing cultivation methods. The quality of former (over)grazed grasslands near Sóly and pasturing lands near Vad parlag, where grazing was finished also turned more valuable. However the ground cover of species with best feeding value reduced, but feedig value of grasses increased due to the increasing of the cover ground of grasslands. In those grasslands, where the cultivation was finished, after initial increasing of number of species many shrubs appeared on the area, and this process will accelerate in the future. Because of this grazing is necessary with appropriate animal density.

The Special Value of Pastures in Hungary
5-24Views:77For centuries, Hungary used to be a beef store for European cities, from Strasburg to Venice. The cattle born and raised on Hungarian pastures were favoured for the excellent quality meat they produced.
In the 19th century, the tradition of keeping livestock on pastures was gradually replaced by stabling and feeding farm animals with monocultures grown on ploughland. The best pastures were ploughed over and only 30% of those that survived were actually used for grazing. Today, it is mainly pastures in national parks that are used for grazing, while this practice is not typical elsewhere.
Based on several decades’ experiments, it can be established that grazing livestock has several beneficial effects:
– pastures provide the most valuable feed for livestock, which sustain their good health conditions,
– livestock cease to be a source of environment pollution for towns and villages,
– manure raises the nutritive value of pastures,
– all the above makes farming more economical
This study provides evidence for the above, based on experiments and production experience. -
Conservation survey of horse pastures and hayfields in an equestrian centre near Sukoro
37-46Views:24The test was carried out in Sukoró, on the lawns of the Sukoró Equestrian Center in May 2023. The purpose of the survey was to present the natural state and economic value of grasslands with different uses. The ceenological surveys were carried out using the Braun-Blanquet method, during which we recorded the data using 2x2 meter squares and gave the cover values in %. The squares were placed randomly in the given areas. During the survey, we analyzed five sample areas in three units. Our sample area I. is degraded fresh grassland, which was a horse pasture that was overgrazed in 2023, II. the sample area was a meadow dominated by sedge, which is utilized by mowing. The III. the sample area is Siki lawn dominated by Festuca pseudovina, which was also mowed. The IV. the deepest part of the mowing area, marsh meadow-fen, which is also used as a mowing area. Sample area V is silicate rock grassland, which is also grazed by horses, but was left alone in 2023.
With the exception of sample area I, which was intensively grazed in 2023, and therefore overgrazed by trampling, based on the tests, the natural state of the lawns remained valuable even after treatments, mowing and grazing. In the lawns, the largest proportion of elements of the native flora can be found. In the deeper spot on the mowing field, bog elements and the protected species Anacampts pyramidalis also appeared. A protected species, Allium sphaerocephalon, also occurred in the silicate rock lawn. The lawn management methods carried out by the riding center are suitable for maintaining the area's vegetation in a close-to-nature and long-term manner.
