Utmarksbeite kan gi like bra tilvekst og slaktevekt som innmarksbeite hos diekalv, men det er avhengig av beitesesong og kvaliteten til utmarksbeitet. Det var liten verknad av utmarksbeite på feittsyresamansetjinga av feittet i ytrefileten

With the objective of studying the effects of production systems on meat quality, 75 Norwegian White Sheep lambs were subjected to one of the following treatments: continuous grazing on a semi-natural lowland pasture until slaughtering (Control); continuous grazing followed by either stall-feeding on concentrate and grass silage or grazing ryegrass pasture for 44 or 24 days before slaughtering (Conc44, Conc24, Rye44, Rye24). Loin samples of M. longissimus dorsi including the subcutaneous fat were analysed for sensory attributes and fatty acid composition. Compared with the control group, a lower intensity of acid taste (P<0.05) and a lower content of C18:3n-6 fatty acids (P<0.001) were observed in the Conc44 group. The n-6/n-3 ratio was higher (P<0.001) in meat tested from the concentrate treatments compared to the ryegrass treatments. These findings indicate that the fattening of lambs on improved pastures or a concentrate-based diet prior to slaughter may alter meat characteristics.

The challenges of grassland management are not quite the same in different European countries. I have always been of the opinion that there is a lot to learn by visiting other countries and by participating in international conferences. I have on two occasions stayed a year at research institutes in Europe. My first stay was in Switzerland, where I had the opportunity to work on a specific subject; biological nitrogen fixation in white clover. On my second stay, at North Wyke in 1997-98, I had a much broader approach. I wished to work with several of the research groups at the Station in order to learn about research methods and results. All members of the staff had a positive attitude to me as a visiting scientist, and they were helpful and did not seem to be tired of all my questions on research issues, or on social and political conditions in Great Britain.

Enga må slåast ung og ofte dersom  grovfôret skal ha høg potensiell næringsverdi.  Ein slik intensiv haustepraksis vil ein forvente gir lågare avlingar og ei mindre varig eng i høve til ein praksis med sjeldnare og/eller seinare slåttar. Desse spørsmåla har ein sett nærare på i prosjektet "Mer og bedre grovfôr som basis for norsk kjøtt- og mjølkeproduksjon ". Ein fann moderate avlingstap med tidlege og hyppige slåttar.

There is hardly any commercial growing of agricultural crops for energy purposes in Norway. Cereal straw is to some extent used as solid biofuel. There is no reason to believe that production of energy crops will increase significantly in Norway in the near future, partly due to political reasons. In Denmark, Finland and Sweden cultivation of energy crops has been commercial for several years. The objective of this presentation is to give a review of the significance and types of possible energy crops in Norway, focusing on crops for biodiesel and solid biofuel.
