  A literature review was done on the selection and utilization of grass species by beef cattle in the Limpopo province. The literature study was complimented by research done on the Towoomba Research station and the University of Limpopo, both in Limpopo Province, in South Africa. The Province is well known for its low rainfall and good quality rangeland. The main aim was to categorize the most important grass species in different utilization (palatable) classes. The thirteen grass species which were under investigation could be classified as follows: Highly palatable species: Panicum maximum and Urochloa mosambicensis; Palatable species: Digitaria eriantha, Heteropogon contortus, Schmidtia pappophoroides and Themeda triandra. Less palatable: Trachypogon spicatus and Themeda triandra and Least palatable: Eragrostis rigidior, Hyparrhenia hirta, Pogonarthria squarrosa, Melinus repens and the Aristida species.

  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.

       A szerzők arra kerestek választ, hogy a húsmarhatartásban a bikaborjak kiegészítő abrakolása milyen hatással van a borjak növekedésére és a tehenek kondíciójára.
       Két egymást követő évben összesen 65 tehén + borjainak vizsgálatai alapján megállapították, hogy a kiegészítő abraketetésben részesült bikaborjak súlygyarapodása 7,4%-kal nőtt, mindehhez átlagosan 2,73 kg napi abrakfogyaszlás párosult. A választást követő hízlalásban nem volt különbség a korábban legelőn abrakolt, ill. abrak-kiegészítésben nem részesült borjak teljesítménye között.
       A borjak kiegészitö abrakolása nem befolyásolta a tehenek legeltetés alatti súlyváltozását és kondícióját. 

• The Special Value of Pastures in Hungary

  For 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.

  From 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.
