Norwegian lamb meat production is mainly based on free grazing in mountainous pastures during the summer. Prior to slaughter in the autumn, some lambs not big enough for slaughter are finished on e.g. cultivated pastures. This study looked at the feed quality of different forages, and the effect on lamb meat quality. Lambs grazed on mountain pastures at Kvaløya in Northern Norway (69°N) and Sør-Fron in Mid Norway (58°N) in 2007, and a subgroup at each location was finished on cultivated pastures for 6 weeks prior to slaughter in September. The fiber content was significantly higher in the cultivated pasture in Mid Norway compared to the mountain pasture while no differences between pastures in Northern Norway were found. In Mid Norway the content of polyunsaturated fatty acid (18:3) was significantly higher in meat from lambs grazing the mountain pasture compared to lamb grazing the cultivated pasture. For Northern Norway, the opposite pattern was observed. The higher 18:3 content may be attributable to lower fiber content at the mountain pasture. In our study, there appears to be an effect of fiber content on the fatty acid composition in lamb meat.

The objective of this study was to evaluate the importance of geographic origin and grazing system for Norwegian and Italian consumers" probability of buying lamb meat. The study consisted of a qualitative part with focus groups followed up with a quantitative survey in each country. Included in the survey was a conjoint design with origin of the meat (Norway, Italy and New Zealand) and pasture (lowland pasture and mountain pasture) as factors, plus questions about consumers" motives underlying selection of food. Results from the study shows that country of origin is important for consumers" buying probability of lamb meat, in both countries domestic meat was preferred. In addition, a higher probability of buying meat from lamb grazing on mountain pasture than from lamb grazing on lowland pasture was identified. It is important for producers of lamb meat to increase the communication of these elements in a competitive national and international food market

Innen økologisk landbruk er man generelt opptatt av å ha god dyrevelferd og å gi dyrene mulighet til naturlig atferd. Hensikten med luftegård er at dyrene der får tilfredsstilt behov som fjøset ikke oppfyller. Kravet om lufting av okser i økologisk storfeproduksjon trådde i kraft i 2008. Dette kravet har gjort at mange økologiske storfeprodusenter har valgt å slutte med okseoppdrett. Oksekalvene selges i stedet til framfôring ved konvensjonelle bruk. Dette er ikke en heldig utvikling sett fra et økologisk ståsted. Målet med prosjektet "Luftegårder for okser i økologisk kjøttproduksjon" var å kartlegge atferdsmessige, driftsmessige og helsemessige faktorer knyttet til luftegårder for okser, samt å utarbeide en praktisk veileder om bruk og utforming av luftegårder til okser.
