  The first part of this review papers presents the history of tall fescue endophyte toxicosis, which used to be a real constraint on grazing beef industry in southern US. The second part reviews some up-dated scientific publications, dealing with vitamins, fats and fatty acids in grass, grass products as well as in animal products produced on these feedstuffs. The papers cited prove that inclusion of grass or conserved (hay, silage) grass in the diets for cattles (beef and dairy) pigs or poultry (broiler chicken and leying han):

  - reduces the fat content of the body
  - improves some vitamin contents of animal products (milk, butter, meat, eggs)
  - improves the unsaturated fatty acid contents of the same animal products.

  The consumption of these high quality animal products consequently may contribute to better human health status of consumers.

  The successful life of Tessedik has been studied for about two centuries by the researchers. From among his activities of public utility the modernization of agricultural production is extremely outstanding.

  His theoretical and practical work covers the main elements of farming of that time period. His results can be studied in the comprehensive system of fooder production, grassland farming and animal husbandry by the analyses of his papers. In his theoretical works he describes the practice of fodder production and feeding of his age as well as the possibilities of more successful farming. His recommendations could be applied only partially among th given economical conditions.

  The aim of our study is to find the most appropriate method for examining the impact of small, extensive livestock/mixed farms on climate change. We would like to describe a self–developed calculation, the application of which requires basic mathematical knowledge. With the method, we get an analysis that can be prepared in a short time, either in the case of real farms or model farms that exist in theory. In order to use it, a detailed description of a farm must be prepared, with the help of a year's work process, annual purchases and the summation of annual production. By drawing conclusions from the obtained results, the farm's GHG emissions can be optimized, and it can also help to find climate–neutral farming methods for the production of animal products.

  Economic 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.

  Grassland 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.

  Understanding global climate change and finding ways to curb it is one of the greatest scientific challenges of our time, a number of studies examining the climatic effects of agriculture, including animal husbandry. Analyzing the most common methods of studying the climatic effects of animal husbandry, we can say that each method has its own shortcomings, their practical application is often difficult, and their results can be contradictory. In articles examining CO2 emissions from grasslands, we often come across results that contradict basic in-kind observations. In my opinion, it is worthwhile to define exactly what is meant by animal husbandry in the research on the topic, as there is no uniform conceptual definition, and in the future it would be expedient to develop a method for calculating GHG emissions from small livestock farms.

  A munkában a Szendrei-féle családi gazdaság szarvasmarha legelőjének és a kaszálójának növényzetét vizsgáltuk. A cönológiai vizsgálatokat 2 alkalommal végeztük, 2018 májusában és szeptemberében 5×5 méteres mintavételi területet alkalmazva, és a fajok borítási %-át megadva. A relatív ökológiai mutatók közül a relatív nitrogén (NB), a relatív talajnedvesség indikátor számai (WB), a természetvédelmi értékkategóriák (TVK), a szociális magatartás típusok (SBT) értékeit használtuk a vegetáció elemzésére. Az adatok főkomponens elemzését (PCA) és detrendáltkorreszpondencia elemzését (DCA) is elvégeztük. A vizsgálat eredményeként az egyik legnagyobb különbség a két vizsgálati terület között a pázsitfüvek arányában van. A legelőkön, a legeltetés hatására eluralkodó hasznos pázsitfüvek aránya 1:3, jelentősen magasabb volt a kaszálóhoz képest. A kaszáló területén a gyomok aránya is magasabb volt, a legelőn pedig a zavarástűrők mennyisége volt jelentősebb. Összességében elmondható, hogy a legeltetéses extenzív állattartás egy fenntartható gazdálkodási technológia, ami kedvező a környezetre és egyben a gazdálkodó számára is megélhetést biztosít.

  Climate change-induced extreme changes are making phytomass yields of extensive grasslands in continental areas increasingly dependent on the season. This situation is exacerbated, inter alia, by the decline in grazing livestock production due to a lack of quality labour, and thus by an increase in the proportion of unused or under-utilised grassland. In our experiments, we have refined the effects of a decade of zero, mulch, mowing and meadow utilisation on carbon emissions, soil moisture and soil temperature during two different types of years. We found that zero tillage with accumulated duff in the absence of utilization had the highest carbon dioxide emission values in different years, even at lower soil moisture values. Our results confirm the fact that fallow grasslands can be considered a source of risk due to their increased greenhouse gas emissions.

  Fenékpusztán, a Balaton egyik természetes állapotában megmaradt partszakaszán, 1999-ben magyar szürkemarha csorda került elhelyezésre idegenforgalmi és természetvédelmi kezelési szempontból. A három éves tapasztalatok alapján a magyar szürkemarha legelési sajátosságai, a legelőfű tér- és időbeli hozzáférhetőségének szabályozásával, gépi kaszálással és a védett fajok populációinak egyedi védelmével kiegészítve jól alkalmazhatók a tájgazdálkodási és természetvédelmi célok megvalósításában.

  For one thousand years the Hungarians kept animals on pastures and lived from animal husbandry by selling their livestock in western Europe.
  In the 19^th cebtury they began to keep animals in stalls, feeding them with monocultures grown on plough lands. The quality of their animals deteriorated in this manner, and keeping them became expensive. Some of the original pastures were broken up, others turned into woodland and only 30% remain today. Between 1975-1995, th ruminant livestock in Hungary fell by 43% due to the price policy.
  According to research and experience gained on agricultural farms, keeping animals on pastures is fruitful, proper from a professional in addition point of view and significantly reduces environment pollution. It would thus advisable to readopt the method of animal husbandry based on grazing.

  Harmincadik alkalommal került megrendezésre az Európai Gyepgazdálkodási Szövetség (European Grassland Federation) nemzetközi konferenciája (30th General Meeting of the European Grassland Federation), 2024. június 9-13. között, ezúttal a hollandiai Leeuwarden-ben.
  Idén a rendezvény szervezői a gyepek általános szerepére, fontosságára és ökoszisztéma szolgáltatásaira helyezték a hangsúlyt (Why Grasslands?). A résztvevők arra keresték a választ, hogy milyen jövő előtt áll a legeltetéses állattartás, illetve milyen egyéb szerepe lehet még a gyepeknek Európában.
  A szakmai program a legeltetéses állattartással érintett résztvevők műhelymunkájával (Grazing Workshop) indult a konferenciát megelőző napon, amely öt fő területre fókuszált:

  • Állategészségügy, állatjóllét
  • Ráfordítás csökkentés
  • Szennyezés ill. kibocsátás csökkentés
  • Biodiverzitás megőrzése
  • Biodiverzitás növelése
