Goat diet supplementation with linseed oil (LO) can be a fruitful technological strategy to enhance the nutritional value of milk fat. The objective of the present study was to determine the effect of LO in a basal diet rich in starch on goat milk fatty acid (FA) profile. The FA contents were monitored exhaustively during 24 h after LO supplementation or elimination by gas chromatography. Rumenic acid, the main conjugated linoleic acid isomer and α-linolenic acid, both related with bioactive properties, significantly rose in milk between 12 and 24 h after the inclusion of LO in the diet. On the contrary, medium-chain saturated FA decreased. Changes in other nutritionally relevant milk FA as well as short term effects caused by dietary LO suppression are discussed.
