| Red clover and high proportion of forage in dairy cow diet increases the concentration of bioactive substances in milk, e.g. unsaturated fatty acids and antioxidants. In the present experiment twenty-four Swedish Red dairy cows were fed three silages in a Latin Square design to study the effect of silage botanical composition and harvest time on milk fatty acid, α-tocopherol and β-carotene concentration. The silages were red clover/grass silage (mixture of first and second cut), red clover/grass silage (mixture of first, second and third cut) and birdsfoot trefoil/grass silage (mixture of first and second cut). Botanical composition and harvest system affected silage vitamin and fatty acid concentration with higher concentrations of α-linolenic acid,... |

| Phytoestrogens are hormone-like substances in plants that can substantially influence human health (positively or negatively), and when fed to dairy cows are partly transferred to their milk. The aim of this study was to investigate effects of varying the botanical composition and regrowth interval of legume-grass silage on phytoestrogen intake and milk phytoestrogen concentrations. In one experiment, 15 Swedish Red dairy cows were fed two- or three-cut red clover-grass silage, or two-cut birdsfoot trefoil-grass silage. In a second experiment, 16 Norwegian Red dairy cows were fed short-term ley silage with red clover or long-term ley silage with white clover, and the effects of supplementation with α-tocopherol were also tested. There were high... |

| Fytoöstrogener är ett samlingsnamn för östrogenliknande ämnen som finns i växter, t ex i baljväxter som klöver och lusern. Inom djurproduktionen beror intresset för fytoöstrogener på de effekter som de kan ha på t ex fertiliteten hos får. Det finns även en stor marknad för humana preparat, ofta baserade på rödklöver, som används som behandling under klimakteriet istället för syntetiska östrogentillskott. Fytoöstrogener delas in i olika grupper baserat på kemisk struktur. De största grupperna är isoflavoner, som finns i vallbaljväxter som rödklöver, och lignaner, som finns i både baljväxter och spannmål. Daidzein och formononetin är exempel på isoflavoner i vallväxter och de kan med hjälp av vommikrober metaboliseras till equol. Secoisolariciresinol och... |

| Concentrations of α-tocopherol and β-carotene in forage species at various maturities were studied in Scandinavia. Red clover (RC)/timothy (TI), RC/meadow fescue (MF), and birdsfoot trefoil (BT)/TI mixtures were grown in Skara and Umeå, Sweden. RC/TI,RC/perennial ryegrass (PR), white clover/PR and BT/TI were grown in Foulum, Denmark. Forages in Sweden were cut one week before heading (BH), at heading and one week after heading of TI. The regrowth was cut six and eight weeks after each harvest in the spring growth cycle. In Denmark, one first harvest and three regrowths were taken. Results from Skara and Foulum are presented. Highest concentrations of α-tocopherol and β-carotene (mg kg-1 DM) in legumes were found in BT grown in Skara (49.8 and 69.6 in... |

| Intake of dietary phytoestrogens has received a great deal of attention due to their potential influence on hormone-sensitive cancers such as breast and prostate cancer. Cow´s milk contains phytoestrogens and the content varies according to the composition of the feed and the type and amount of legumes used. In this study we evaluated the proliferative effect of milk with different phytoestrogen content in human breast (MCF-7) and prostate cancer cells (PC-3). Milk was obtained from cows fed either a birdsfoot trefoil-timothy silage based ration (B1) or two different red clover silage based diets (R1 and R2) resulting in total phytoestrogen contents of 403 ng/ml, 1659 ng/ml and 1434 ng/ml for the B1, R1 and R2 diets, respectively. Whey was produced from... |

| The effect of silage botanical composition and harvest system on organic milk composition was studied in a feeding trial. Twenty-four Swedish Red dairy cows in mid lactation were allocated randomly to three treatments in a 3×3 Latin square design with each period of three weeks. The treatments were birdsfoot trefoil (Lotus corniculatus L.)/grass silage in two-cut system (B, 16 % birdsfoot trefoil), red clover (Trifolium pratense L.)/grass silage in two-cut system (R2, 42 % red clover) and red clover/grass silage in three-cut system (R3, 38 % red clover). Milk samples from the last week in each period were analyzed for fat and protein concentration. Milk yield was 28.7 ±1.0, 30.3 ±3.2 and 28.6 ±1.4 kg ECM day-1 (mean and SD) for treatment B, R2 and R3... |
