Última Conjugated linoleic acid isomer concentrations in milk from high- and low-input management dairy systems 21 Butler, Gillian; Collomb, Marius; Rehberger, Brita; Sanderson, Roy; Eyre, Mick D.; Leifert, Carlo. BACKGROUND: Different conjugated linoleic acid (CLA) isomers are known to have contrasting physiology or health effects and there is growing evidence that the profile of natural isomers in milk is influenced by the production system. This survey is the first to compare feeding regimes and concentrations of 14 CLA isomers inmilk from three production systems in the UK. RESULTS: Total CLA and seven isomers (including C18 : 2 c9t11 which comprised >80% of total) were significantly higher in milk from both organically certified and non certified low input (LI) systems compared with milk from conventional high input farms. Sampling date also affected concentrations of total CLA and nine isomers; being lowest in March and highest in August. Seasonal...

A trial was carried out to investigate the influence of forage from temporary or from permanent grassland as well as permanent grassland supplemented with maize silage on the milk fat composition. The trial lasted seven weeks: two weeks of adaptation period and five weeks of experimental period. The forage was offered ad libitum in the stable. None of the cows received concentrates, only a mineral supplement was added. Both feed intake as well as milk production were recorded daily. Before the trial and three times during the trial milk samples were taken and in addition to the fat, protein and lactose content different fatty acids in the milk fat were analysed. The variant with the forage from the permanent grassland had, in comparison with the...

Ano: 2009 URL: http://orgprints.org/14054/1/Wyss_14054.pdf Influence of a dry fractionation of butterfat on the content of fatty acids including conjugated linoleic acids 21 Rehberger, Brita; Bütikofer, Ueli; Bisig, Walter; Collomb, Marius. There is a growing demand among consumers for food products with natural nutritional-physiological advantages over comparable conventional products. As part of an EU project, a process using dry fractionation is evaluated that enables the targeted lowinput enrichment of conjugated linoleic acids (CLA) in milk fat. Furthermore, the distribution of CLA isomers in the fat fractions was analysed. In the olein fraction for highland butter a CLA enrichment of 15.3% was obtained. The yield of the CLA rich olein fraction was 44.5% of the total amount of olein and stearin. There were significant increases during the first fractionation step of highland butter for the concentration of the CLA isomer cis-9, trans-11 (P £ 0.05) and during the second fractionation...
