The aim of this work was to evaluate the effects of dietary fat supplements on the fatty acid (FA) composition of milk from goats in early lactation. Sixteen Sarda breed goats, fed 1.5 kg per day of concentrate and hay ad libitum: eight goats were supplemented with fat from linseed (LIN) with a high C18:3 content, and eight received fat from cottonseed (COT) with a high C18:2 content for 5 weeks: a 2-week preliminary period (PRE), a 2-week experimental period (EXP) and 1 week of recovery where the fat supplement was removed (REC). The FA profile of the goats' milk was determined by gas chromatography. The milk FA profile did not differ between PRE and REC periods. In the EXP period the milk FA profile was significantly influenced by the fat source. The results suggest that it may be possible to enhance the nutritional value of goat milk fat in early lactation by adding linseed to the diet
