| White clover (WC, Trifolium repens L.) or red clover (RC, Trifolium pratense L.) was grown in mixture with grasses. Samples of the mixtures and pure clovers were taken during three cuts, and the fatty acids (FA) compositions were determined. The clover species had no significant effect on the individual FA contents of the leys (g kg-1 dry matter (DM)), nor on the total FA content. Pure clovers had lower content of all individual FA (8.2 vs. 12.4 g kg-1 DM) than mixtures; the contents of all FA decreased with increasing percentage of clover in the mixture, but the decrease was weaker for C18:3n-3 than for the other FA. Although pure WC and RC had similar FA contents, the relative proportions (percentage of total FA content) of C16:0 and C18:3n-3 differed;... |

| Relationships among commencement of luteal activity (C-LA), milk yield, and energy balance (EB) were investigated in 3 selection lines of Norwegian Red cows at the Norwegian University of Life Sciences from 1994 through 2001. The cows were selected for low genetic merit for milk yield (LMP), high genetic merit for milk yield (HMP), and a combination of high indices for milk yield and fertility (HI). Breeding values for fertility were based on 56-d nonreturn rate. The material included 268 lactations from 147 cows. Milk samples for progesterone analysis were drawn 3 times weekly from 1994 through 1998, and 2 times weekly from 1999 to 2001. Commencement of luteal activity was defined as the first 2 consecutive measurements of progesterone concentration >3... |

| Diekalvproduksjon på utmarksbeite kan gi like stor tilvekst og slaktevekt som tilsvarende produksjon på innmarksbeite. Begge beitetypene gav meget god kjøttkvalitet med kun små forskjeller i kvalitet mellom kjøtt produsert på inn- og utmark. Prosjektet er gjennomført av Nortura og Bioforsk med besetninger av forskjellige storferaser fra Lillehammer, Gausdal, Øyer og Ås. |

| Daglig opptak av surfôrtørrstoff, energi og protein var langt høgere hos NRF kyrne enn STN kyrne. NRF kyrne hadde også et påviselig høgere opptak av grovfôr og NDF enn STN kyrne uttrykt per 100 kg kroppsvekt.STN kyrne la mer på seg enn NRF kyrne, og kyrne som fikk kraftfôr la mer på seg enn kyr uten kraftfôr, men verken rase eller kraftfôrnivå hadde signifikant effekt på dyras vektendring. Det ble ikke påvist noen signifikante samspilleffekter mellom rase og kraftfôrnivå på noen av opptaksparametrene.Som forventet produserte NRF kyrne mer mjølk og EKM enn STN kyrne, men innholdet av fett og protein i mjølka var høgest hos STN kyrne. Daglig produksjon av fett og protein var imidlertid høgest hos NRF kyrne enn STN kyrne pga høgere mjølkeproduksjon. Hverken... |

| Previous research has shown that grazing pastures compared to feeding preserved forages has large impact on milk fatty acid (FA) composition, but differences between grazing red clover (Trifolium pratense L.) or white clover (Trifolium repens L.) are small, whereas the herbage proportions of dicotyledon botanical families is positively correlated with the milk-fat proportions of total polyunsaturated FA when grazing pastures in the Alps. The objective of the present study was to investigate the influence of botanically different pastures on bovine milk composition and milk susceptibility to oxidation. Two groups of 8 multiparous Norwegian Red dairy cows [mean (standard deviation); 599 (45.1) kg body weight, 73 (15.0) d in milk, 29.9 (2.90) kg milk/d at... |

| The Norwegian government has since 2006 had a goal of 15 % organic food production and consumption, initially by 2015 and later adjusted to 2020. The goal has primarily been justified by consumer demands, and to some extent by environmental benefits. Organic farming is said to be a “spear point” in the development of a more environmental friendly and sustainable agriculture in Norway, but the government’s policy lacks thorough political support and the goal is far from achieved. In 2012, certified land and land area under conversion to organic farming comprised 5.6 % of the agricultural area (Debio 2013). The turnover of organic products was more than 1.1 billion NOK in 2012; an increase of 11 % from 2011 (NAA 2012). In 2009, organic food represented 1.3... |

| 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... |

| Progesterone profiles in Norwegian Red cows were categorized, and associations between the occurrence of irregularities in the profiles and the commencement of luteal activity were investigated. The cows were managed in 3 feeding trials from 1994 to 2001 and from 2005 to 2008 at the Norwegian University of Life Sciences. The cows were followed from calving, and the milk samples collected represented 502 lactations from 302 cows. Milk samples for progesterone analysis were taken 3 times weekly from 1994 throughout 1998 and from 2005 to 2008 and 2 times weekly from 1999 to 2001. Commencement of luteal activity was defined as the first day of 2 consecutive measurements of progesterone concentration ≥3 ng/mL not earlier than 10 d after calving. Delayed... |

| 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,... |
