| 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 the 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. |

| A continuous grazing experiment with three measurement periods, 3 weeks each, was conducted with 16 Norwegian Red dairy cows in mid lactation to compare milk quality when grazing red clover-grass (R) or botanical diverse pasture (D). The cows were offered either R or D from the start of grazing season in mid May until beginning of September 2008. Milk yield was measured and milk samples were collected in the last week in each period (end of June, beginning of August and end of August). Pasture type had no effect on milk yield and milk content of fat or protein. Cows grazing R had higher proportion of the fatty acids C18:0 (22.41 vs. 9.96, P<0.05) and C18:1t11 (0.58 vs. 0.44 g/100g FAME, P<0.05) and lower proportion of C16:0 (27.83 vs. 30.92,... |

| Et kontinuerlig beiteforsøk med 3 perioder à 3 uker ble gjennomført med 16 NRF-kyr i midtlaktasjonen. Målsetningen var å sammenligne melkequalitet når kyrne beitet rødkløvergras (RB) eller botanisk allsidig beite (AB). beitetype hadde ingen effekt på ytelse, melkas fettinnhold eller proteininnhold. Kyr som beitet RB hadde en høyere andel av fettsyrene C18:0 (22.41 vs. 9.96, P<0.05) og C18:1t11 (0.58 vs. 0.44 g/100g FAME, P<0.05) og lavere andel C16:0 (27.83 vs. 30.92, P<0.05) i melkefettet sammenlignet med kyr som beitet AB. Innholdet av alfatokoferol var høyere i melk fra RB enn AB (3.01 vs. 2.64 µg/ml, P<0.05). Den oksidative stabiliteten av melkas lipider ble bare i mindre grad påvirket av beitetype. |

| Bulk-tank milk was collected every second month (in 2007) from 32 farms in Middle Norway to examine the effect of grassland management and farming system on milk composition. Sixteen farms with organic farming system were paired with 16 farms with conventional farming system. In both farming systems, 9 farms had short-term rotational grassland and 7 farms had long-term grassland. Milk fatty acid (FA) composition and milk concentration of α-tocopherol, β-carotene, retinol,phytoestrogens and selenium were analyzed. Only small differences were found in milk composition from farms with different grassland management, except for the concentration of phytoestrogens and selenium that were highest on farms with short-term grassland. Milk FA composition, milk... |
