Summary

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
forage from the temporary grassland, higher proportions of unsaturated fatty acids and
higher contents of omega-3 and of conjugated linoleic acid (CLA). With increasing age
of the forage, the contents of omega-3 and CLA decreased. The addition of maize
silage had a stronger influence on these fatty acids, as the lowest amounts of omega-
3 and CLA were found.
