The effects of linseed feeding on the stearoyl-CoA desaturase (SCD) activity were evaluatedon grazing dairy goats divided into two homogeneous groups (C, control, and L, treated) fed thesame amount of concentrate which, for group L was supplemented with linseed. Milk yield wasunaffected by the treatment. Group L showed significantly higher milk fat (4.10% vs 2.94%,p<0.01)than group S.

In group L, total CLAswere higher than in group S (0.646% vs 0.311%;p<0.01) mainly because of the differences in CLA cis9trans 11 (0.623% vs 0.304%;p<0.01). In treated animals, SCD activity, measured as cis9 C14:1/C14:0,was lower than in the control group, mainly in July and August .

Abstract
The effects of linseed feeding on the stearoyl-CoA desaturase (SCD) activity were evaluatedon grazing dairy goats divided into two homogeneous groups (C, control, and L, treated) fed thesame amount of concentrate which, for group L was supplemented with linseed. Milk yield wasunaffected by the treatment. Group L showed significantly higher milk fat (4.10% vs 2.94%,p<0.01)than group S. Within milk fatty acids, group C showed significantly higher levels of saturated fattyacids and lower values of mono-unsaturated and polyunsaturated fatty acids. In group L, total CLAswere higher than in group S (0.646% vs 0.311%;p<0.01) mainly because of the differences in CLA cis9trans 11 (0.623% vs 0.304%;p<0.01). In treated animals, SCD activity, measured as cis9 C14:1/C14:0,was lower than in the control group, mainly in July and August .I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
