Matching Nutrient Requirements of Farmed Red Deer on Pasture. International and National Experiences: Papers presented at the „Timely questions in grassland and game management” scientific conference (Hungarian Academy of Sciences – Kaposvár University, 18-19 May 2006)
7-12Views:71The authors summarize the factors influencing the nutritional value of grasses which constitute the dominant proportion of pasture biomass, and emphasize the percentage proportion of leguminous species. Interactions are discussed between the phenological status of grasses, digestability, metabolic energy requirements of deer and their voluntary intake. The very often neglected factor of water awailability on feed effciency in red deer farming is stressed. Some data are presented considering the research results obtained at the red deer research farm of the University of Kaposvár.

Let us have our livestock grazed! Appreciation of a carrier devoted to grassland science on the 85th birthday of Prof. Imre Vinczeffy
93-94Views:97Vinczeffy Imre nyolcvanöt évvel ezelőtt született Olasztelken, Udvarhely megyében. Iskolai tanulmányait Székelyudvarhelyen, a mezőgazdasági főiskolát Kolozsváron végezte. Már gyermekkorában felkeltették érdeklődését a természet, a növény- és állatvilág csodái. Pallagon szerezett diplomát 1947-ben. Eddigi fontosabb beosztásai: egyetemi tanársegéd 1950-ben, adjunktus 1952-ben, docens 1954-ben, szakmunkás 1957-ben, tudományos munkatárs 1962-ben, főmunkatárs 1968-ben, egyetemi tanár 1970-ben. A „Veszprém megye gyepgazdálkodása és fejlesztésének lehetőségei” című gyeptipológiai dolgozattal doktorált 1962-ben, „A gyepek termőképességének vizsgálata” témával kandidált 1965-ben, és „A gyepek állateltartó képessége” című, 1985-ben benyújtott dolgozatával szerzett MTA doktori fokozatot.

Analysing of yield and nutritional value of Zselic pastures and its evaluation by D-e-Meter system
33-38Views:56The future way of grassland management is greatly influenced by the new functions of the grasslands relative to the environment. This means that the role of raising nutrition will be expand by the role of keeping the natural resources. In the EU the price of the arable lands are controlled by the supply and demand, so the quality of the arable and the value of it come asunder. The market economy has to evaluate the arable reliable and accurate. In according to these sentences it is necessary to show the real value of soil quality, of arable in the register of estate. An important part of the sustainable developing is to find the adaptation to the local area and the nature. This aspect could be found in the multifunctional European Agricultural model and in the rural development too. Nowadays we use the way of the land evaluation known as the “aranykorona”, which is an obstacle to the way of the sustainability. The evaluation of grasslands in Hungary is not solved, the details we have are disused, so it is hard to plan the yields of the grasslands, we can estimate them a posteriori. In the D-e-Meter grassland module we start the evaluation with the DM yield of the characteristic grass. This starting point is modified with the factors proper to the area. The measured and the estimated DM yield were compared to each other at 3 grassland at Bőszénfa. To evolve an up-to-date evaluating system we analysed grasslands at the University of Kaposvár Deer Farm at Bőszénfa to find answers to the followings:
• Soil analysis of the humus, the N, P, K levels and the pH of the grasslands
• Describe the botanical composition by the Balázs-method
• The quality and the nutrition value of the grasslands
• Yearly yields of grasslands
• Analyzing of the results by the D-e-Meter system

Expectable changes in the utilization of pastures: Papers of the „Challenges and Aspects in Grassland Management” conference held on 22-23 May 2008.
9-12Views:55Analysing the past and the future facts and figures of the Hungarian pasture management the authors has been found the following: − In the period between 1993 and 2003 it was generally believed, that the total area of pasture will be increasing in the future. This forecasting comes not be true. − In the period between 2004 and 2008 the Hungarian pasture area decreased with 13%. We can realise decreasing in the total yield and the yield to/ha too. At the same time in the National Parks and on other protected pastures the grassland management was improved. − Analysing the estimated stock of grazing animal and the necessary pasture area the authors give the main features of the Hungarian pasture utilization in the period after 2008.

Results of grazing preference investigations incounty and abroad
21-25Views:53Many 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.

Some aspects of red deer farming bared on grassland
49-50Views:72A szerzők tanulmányukban összefoglalják a legelőre alapozott gímszarvastartás néhány legfontosabb kérdését a legelöhasznosítás szempontjából. A legelö metabolizálható energiatartalma növekedésével lineárisan javul a szarvasborjak napi tömeggyarapodása a szoptatási idószak azon szakaszában, amikor a borjak legelőfű felvétele számottevó.
A gyepek pillangós alkotóinak növekedésével 0-20% közötti tartományban nagyon jelentös a legelő állatok napi tömeggyarapodás javulása. 20% feletti pillangós arány már kismértékű tömeggyarapodás többlettel jár, és ugyanakkor negatív hatású a területi termelékenységre.
