| Økologisk melk produsert på rødkløvergrasbeite (RB) eller botanisk allsidig beite (AB) ble analysert for fettsyresammensetning, vitamininnhold og oksidativ stabilitet. Hypotesen i forsøket var at melk produsert på RB har et høyere innhold av flerumettede fettsyrer og at melkefettet dermed er mer utsatt for oksidasjon enn melk produsert på AB. Det var også forventet å finne et høyere innhold av vitaminer i melk produsert på RB enn på AB som kan hemme oksidasjonsprosessen. I et kontinuerlig produksjonsforsøk gikk to grupper à åtte kyr (Norsk Rødt Fe) i tre perioder à tre uker på henholdsvis RB (28 % rødkløver, 19 % timotei, 33 % engsvingel, 17 % andre urter) eller AB (21 % hvitkløver, 19 % engrapp, 17 % timotei, 15 % engsvingel, 3 % rødkløver, 9 % andre... |

| 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... |

| Metabolism of the isoflavones biochanin A, genistein, formononetin, daidzein, equol and prunetin, the lignans matairesinol, secoisolariciresinol, enterodiol and enterolactone and the coumestan coumestrol was investigated to study the metabolism of phytoestrogens in dairy cows, and the possibilities to influence the content in milk. Four Norwegian Red Cows where allocated in a 4x4 latin square with four different silages. Silages had different botanical composition; red clover, botanical diverse, perennial ryegrass and timothy. The concentration of phytoestrogens was measured in feeds, omasum phases, feces, urine and milk by using the liquid chromatography (LC)-mass spectrometry (MS)/MS technique. Metabolism in reticulorumen and in digestive tract as well... |

| Literature data from experiments with lactating dairy cows offered silage-based diets was reviewed to evaluate the effects of the grassland legume species Trifolium repens (WC, white clover), Trifolium pratense (RC, red clover) and Medicago sativa (M, lucerne) on feed intake, milk production and milk quality. Seven data sets were created to compare grass silage (G) with grassland legumes in general(L), G with RC, G with WC, G with M, RC with WC, RC with M and different silage proportions of RC. Daily dry matter intake and milk yield were on average 1.6 and 1.6 kg, respectively, higher and milk fat content 1.2 g/kg milk lower on L than on G based diets. Similar differences were found when G was compared with RC or WC diets. Cows offered WC yielded 1.1 kg/d... |

| Fettsyresamensetning og innhold av vitaminer i melk ble i stor grad påvirket av sesong og produksjonssystem og i mindre grad av engalder. Beitesesongen hadde gunstig effekt på fettsyresammensetning sammenlignet med innefôringsperioden, mens økologisk driftsform hadde gunstige effekter som økt andel av C18:3c9,12,15 og negative effekter som økt andel mettede fettsyrer. Hovedfaktorene bak de observerte effektene antas å være fôrrasjonens andel av kraftfôr, beiteopptak, rødkløver og kraftfôrets innhold av lipider. |

| Bulk tank milk from 28 dairy farms was sampled every second month for 2 yr to assess the effects of grassland management, production system and season on milk fatty acid (FA) composition, concentrations of fat-soluble vitamins, Se, and milk sensory quality. Grassland management varied in terms of time since establishment. Short-term grassland management (SG) was defined as establishment or reseeding every fourth year or more often, and long-term grassland management (LG) was defined as less frequent establishment or reseeding. Fourteen organic (ORG) dairy farms with either short-term or long-term grassland management were paired with 14 conventional (CON) farms with respect to grassland management. Within ORG farms, SG farms differed from LG farms in... |
