  Glycerol is a by-product of the biodiesel industry and it might be a good alternative to moderate the energy deficiency of sows during the lactation period. Preliminary experiments were carried out to test the effect of a powder, solid based “food grade” glycerol source with 72.9% glycerol content (Trial 1) and a liquid “feed grade” glycerol source with 86% glycerol content (Trial 2) on the performance of lactating sows and their litters. Trial 1 was conducted with 5 Hungarian Large White×Hungarian Landrace sows/treatment (313±24.9 kg) and Trial 2 with 12–12 DanAvl (323±17.0 kg) sows and their litters/treatment. Neither the solid, powder based glycerol (Trial 1), nor the liquid glycerol source (Trial 2) had significant effect on the feed intake, reduction in live weight and back-fat thickness, and weaning-tooestrus interval (p>0.05) of lactating sows. In Trial 2, on the 14th, 21st and 27th days of lactation the milk samples were collected and it was found that 50 kg/t glycerol decreased the protein content of milk samples (p<0.05). Glycerol supplementation had no effect on dry matter, fat, lactose content of milk samples (p>0.05). In Trial 2, no significant difference was found between control and experimental sow groups in triglyceride concentration of blood samples and in the activity of liver enzymes (ALT, AST, GGT; p>0.05), but the concentration of plasma glucose and cholesterol increased tendentiously (p<0.10).

  Based on our preliminary results, it can be concluded that additional dose trials are needed to perform in order to study the effect of glycerol supplement on milk production and on metabolic processes of lactating sows.

  Buildings in industry, mining, transportation and for personal and commercial activities cover increasingly more valuable agricultural land. The increase of sub-urbanization and vehicular traffic and the spread of malls and other kinds of investments are causing serious harm for not only to human society, but to a whole national economy as well.
  The law on agricultural land (1994:LV) contains legal rules for the preservation, use and classification of agricultural land. These rules define the temporary or permanent use of land for agricultural and non-agricultural purposes; the scale of the land-protection fee and the rules of the process on cases in which land is used for non-agricultural purposes without the consent of the land registry. In the field of land classification, the law prescribes the regulations which are to be followed in order to define the net income of agricultural land in Golden Crowns.
  Hungarian land protection rules are unique in the European Union, because only few member-states have similar laws to ours. Community law does not regulate the member states, except in the case of land classification, because this is the basis of the tax paid on the agricultural lands, but even here, there are differences among the states.

  Responsible leaders of more and more companies build legal, ethic, moral, environmental and social aspects in their goals and values beyond profit maximization. The number of companies whose activities in terms of social responsibility (CSR) has clear connections with promoting and putting forward sports shows an increasing tendency.

  The aim of this study is the conceptual clarification of corporate social responsibility, and emphasize the CSR’s significance in sport management, next the analysis of 3 top food and beverage companies’ (Coca-Cola, Nestle, Danone) CSR activity in special regard to sport management in Hungary and abroad.

  The Agricultural Research and Development Institute P.U.C., Szarvas – realizing the importance of using the biomass in a number of ways – was one of the first in Europe, who began the breeding of grasses suitable for industrial utilization. The possible areas of using the energygrass – which could be called industrial grass – are the following:
  – Energetical use
  – Paper industry use
  – Utilization as an industrial fibrematerial
  – Use for feeding
  The aim of the breeding programme: developing the kinds of grass, which yields big drymaterial mass and suitable for industrial utilization. These kind of grass, taking soil-utilization, economicality and environmental protection, offer and ensure new marketing perspectives and employment facilities for the disadvantageous areas.
