Effects of feeding dairy cows different legume-grass silages on milk phytoestrogen concentration Organic Eprints
Höjer, Annika; Adler, Steffen; Purup, Stig; Hansen-Møller, Jens; Martinsson, Kjell; Steinshamn, Håvard; Gustavsson, Anne-Maj.
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...

Phyto-oestrogens in herbage and milk from cows grazing white clover, red clover, lucerne or chicory-rich pastures Organic Eprints
Andersen, Charlotte; Nielsen, Tina Skau; Purup, Stig; Kristensen, Troels; Eriksen, Jørgen; Søegaard, Karen; Sørensen, John; Fretté, Xavier C.
A grazing experiment was carried out to study the concentration of phyto-oestrogens in herbage for cattle and in milk during two periods (May and June). Forty-eight Danish Holstein cows were divided into four groups with four treatment diets; white clover, red clover, lucerne and chicory-rich pastures. Each experimental period lasted 15 days. Herbage samples from the first day and individual milk samples from the last day of the experimental period were analysed for phyto-oestrogens using LC-MS technique. The total concentration of phyto-oestrogens was 21 399 mg/kg DM for red clover and 238-466 mg/kg DM for the other three herbages mainly due to a much higher concentration of biochanin A, formononetin and glycitein in red clover. In the milk, the total...

Phytoestrogens and Their Metabolites in Bulk-Tank Milk: Effects of Farm Management and Season Organic Eprints
Adler, Steffen A.; Purup, Stig; Hansen-Møller, Jens; Thuen, Erling; Steinshamn, Håvard.
Phytoestrogens have structures similar to endogenous steroids and may induce or inhibit the response of hormone receptors. The objectives of the present study were to compare the effects of long-term vs. short-term grassland management in organic and conventional dairy production systems, compare organic and conventional production systems and assess seasonal variation on phytoestrogen concentrations in bulk-tank milk. The concentrations of phytoestrogens were analyzed in bulk-tank milk sampled three times in two subsequent years from 28 dairy farms: 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. Grassland management varied in...

Proliferative effect of whey from cows’ milk varying in phyto-oestrogens in human breast and prostate cancer cells Organic Eprints
Nielsen, Tina Skau; Höjer, Annika; Gustavsson, Anne-Maj; Hansen-Møller, Jens; Purup, Stig.
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...

Phyto-oestrogens and their metabolites in milk produced on two pastures with different botanical compositions Organic Eprints
Adler, Steffen A.; Purup, Stig; Hansen-Møller, Jens; Thuen, Erling; Gustavsson, Anne-Maj; Steinshamn, Håvard.
Phyto-oestrogens are a group of secondary plant metabolites that may bind to oestrogen receptors and exert oestrogenic or anti-oestrogenic effects in humans and can protect against cancer diseases. When ingested by dairy cows, phyto-oestrogens can be metabolised and transferred to the milk. The objective of this study was to assess the effects of grazing a recently established pasture containing red clover (Trifolium pratense L.) and an older pasture containing a variety of sown and unsown plant species on milk concentrations of phyto-oestrogens. Sixteen Norwegian Red dairy cows [mean (standard deviation); body weight 599 (45.1) kg, stage of lactation 73 (15.0) d in milk, milk yield 29.9 (2.90) kg/d at the start of the experiment] were divided into two...

Effects of clover-grass silages and concentrate supplementation on the content of phytoestrogens in dairy cow milk Organic Eprints
Steinshamn, Håvard; Purup, Stig; Thuen, Erling; Hansen-Møller, Jens.
A 2 × 2 factorial continuous experiment was conducted with 28 Norwegian Red dairy cows in early lactation to compare milk content of phytoestrogens when feeding ad libitum white clover (WCS) or red clover (RCS) grass silages prepared from the second and third cut without and with 10 kg/d supplementation of a standard concentrate. The cows were offered either RCS or WCS for 88 d (period 1) and thereafter a mixed red clover-white clover-grass silage for 48 d (period 2). Total dry matter intake and milk yield were not affected by forage type but increased with concentrate supplementation. Intake of isoflavones was several times greater in RCS than in WCS, whereas intake of lignans was greater in WCS. Concentrate supplementation reduced the intake of most...
