The main objective of this experiment was to compare timothy and X-Festulolium varieties Felina and Felopa as forage for growing bulls. Thirty one-year-old Norwegian Red bulls were assigned to one of the three feeding groups by stratified block randomisation within weight in individual boxes and feeding. The forage was grown at Bioforsk"s research station in Bodø, (latitude: 67.28 °N), Norway, and harvested at a NDF content of 500 g/kg dry matter in the summer of 2008. The grass was ensiled in round balls and fed ad libitum. The bulls were fed a fixed amount of one kg of concentrate/day through the experiment. Animals were slaughtered at a live weight of 600 kg, and the slaughters were classified according to the EUROP system. The animals fed with timothy had an overall larger weight gain than the bulls fed with the X-Festulolium variants, though the weight gain decreased towards the end of the feeding period. The forage consumption in the timothy group was also larger. Grass type had no effect on the on the classification of the slaughters.

Thirty-two dairy farms in Middle-Norway with different grassland systems (short-term (7 years) grassland (L)) and different production systems (organic (O) or conventional (C)) were compared in a field study in 2007. In a principal component analysis on variables including farm details, botanical composition and chemical forage composition the farms were separated into organic and conventional farms with exception of one farm. Amongst the organic farms most SO farms were distinguished from LO farms. Concentration of forage crude protein was positively correlated with proportion of grasses. Concentration of non-fibrous carbohydrates, in vitro digestibility and net energy lactation was positively correlated with proportion of legumes. Species diversity and cutting time at first cut was positively correlated with proportion of non-legume herbs

Milk samples from sixteen Norwegian Red dairy cows grazing mixed swards of either grass-red clover (GR) or mixed swards of sown and unsown species of grass, clover and other herbs (GCH) were collected during four periods. Both pastures were organically managed. Pasture botanical composition had no effect on milk fat, protein or vitamin concentration and only minor effects on fatty acid composition. Milk from GR had higher concentrations of the phytoestrogens equol, genistein and biochanin A than milk from GCH. Concentrations of equol in milk from GR were higher than concentrations reported from experiments with red clover silage. The oxidative stability of the milk lipids was not affected by pasture type

The effects of different production systems on sensory profile and fatty acid composition were examined in a study performed in Northern Norway (65o50"N, 12o28"E) in 2008. One-hundred and fifty Norwegian White Sheep lambs grazed on the same semi-natural pasture with their dams for three months or more. The effect of pre-slaughter fattening on meat quality was compared using a control group of lambs slaughtered directly from the pasture. Four pre-slaughter treatments were established: weaning and indoor-feeding on concentrate and grass silage for either 24 or 44 days before slaughtering (Conc24, Conc44), weaning and grazing on ryegrass (Lolium multiflorum) pasture for the same periods (Rye24, Rye44). Loin samples of M. Longissimus dorsi including the subcutaneous fat over the muscle from fifteen carcasses from each treatment were analysed for sensory attributes and fatty acid composition. A lower intensity of acid taste was observed in meat from lambs in treatment Conc44 compared with meat from lambs in the control treatment. A higher content of the fatty acids C16:0, C18:1n-9 and C18:2n-6 and the n-6/n-3 ratio was related to meat from lambs fed concentrate, while a higher of the fatty acids C18:0, C18:1t-11 and C18:3n-3 was found in meat from grazing lambs.

In experiments at the Western coast of Norway, a dry matter (DM) content regarded acceptable for baling was reached within 6-8 hours after mowing in wide-spread crops as opposed to within 24 hours for swathed crops. Samples containing Clostridiae and butyric acid were more frequent in silages wilted wide-spread for 24 hours and then windrowed than in silages wilted in swaths equally long. This difference in hygienic quality might have been caused by differences in DM content and fermentation in the two types of silages as well as by contamination of soil borne organisms through additional handling and wheeling of wide-spread crops. Rapidly wilted crops and silages had a higher concentration of water soluble carbohydrates (WSC).
