Alpha-tocopherol and b-carotene in legume–grass mixtures as influenced by wilting, ensiling and type of silage additive Organic Eprints
Lindqvist, H.; Nadeau, E.; Jensen, S.K..
Effects of wilting, ensiling and type of additive on atocopherol and b-carotene contents in legume–grass mixtures were examined. Swards of birdsfoot trefoil + timothy (Bft + Ti), red clover + timothy (Rc + Ti) and red clover + meadow fescue (Rc + Mf) were harvested as a first regrowth in August 2005. Forage was wilted to a dry-matter (DM) content of 273 g kg)1 and ensiled without additive or with an inoculant or acid. Wilting decreased a-tocopherol concentration by 30% in the Bft + Ti mixture (P = 0x015). Untreated Bft + Ti silage had higher a-tocopherol content than red clover silages (56x9 vs. 34x2 mg kg)1 DM; P = 0x015). The a-tocopherol concentration of Bft + Ti silages increased during ensiling from 41x1 mg kg)1 DM in wilted herbage to 56x9, 65x2 and...

Alpha-tocopherol and beta-carotene in legume-grass mixtures as influenced by wilting, ensiling and type of silage additive Organic Eprints
Lindqvist, H.; Nadeau, E.; Jensen, Søren K..
Effects of wilting, ensiling and type of additive on a-tocopherol and b-carotene contents in legume–grass mixtures were examined. Swards of birdsfoot trefoil + timothy (Bft + Ti), red clover + timothy (Rc + Ti)and red clover + meadow fescue (Rc + Mf) were harvested as a first regrowth in August 2005. Forage was wilted to a dry-matter (DM) content of 273 g/kg and ensiled without additive or with an inoculant or acid. Wilting decreased a-tocopherol concentration by 30% in the Bft + Ti mixture (P = 0.015). Untreated Bft + Ti silage had higher a-tocopherol content than red clover silages (56.9 vs. 34.2 mg/kg DM; P = 0.015). The a-tocopherol concentration of Bft + Ti forages increased during ensiling from 41.1 mg/kg DM in wilted herbage to 56.9, 65.2 and 56.8...

Vitaminer og fedtsyrer i hø og ensilage – hvad sker der vid forvejring og lagring? Organic Eprints
Jensen, Søren K.; Hymøller, L.; Soegaard, Karen; Lindqvist, H.; Nadeau, E..
For at undersøge stabiliteten af vitaminer i moderne ensilage- og høproduktion, har FØJO III projektet ECOVIT, igennem to vækstår, målt vitaminindholdet i forskellige græsmarksafgrøder ved forskellige høsttidspunkter og sletintervaller. Resultaterne viser, at det største tab af vitaminer og umættede fedtsyrer sker i forbindelse med forvejringen, mens tabet i lagringsperioden er begrænset.
