Effects of different fat-enriched concentrates on fatty acid profile of cheese from grazing dairy sheep

A trial on different fatty acid supplementation was run in grazing dairy sheep. Forty-eight
lactating Sarda ewes were randomly allocated to four homogeneous groups: PAS, control group grazing for
22h/d without supplementation; NOF, group supplemented with a cereal based non-fat enriched concentrate;
C182, group supplemented with a concentrate rich in sunflower seeds; and C183, group supplemented with a
concentrate rich in linseeds. The results showed that the concentrates, based on oilseeds from both sunflower
and linseed sources determined high C18:1 t11 and CLA c9 t11 cheese fat content. Moreover linseeds supplementation
improved the concentration in the cheese of other beneficial fatty acids such as LN and PUFAω3.
