The effects of two levels of ether extract based on rice oil concentrate in 30 Saanen goats during early lactation were evaluated. The feeding was based on the ratio of 60% forage (alfalfa hay) and 40% commercial concentrate with two levels of lipids (3% and 5%). The variables were the quantification and qualification of the fatty acid profile of whole milk and forward to the time of lactation. The addition of rice bran oil in the diet decreased significantly (P<0.05) the concentration of saturated fatty acids and increased (P<0.05) the concentration of polyunsaturated fatty acids in goats' milk. The linoleic acid was also positively affected by the addition of rice bran oil in the diet. The inclusion of rice bran oil at levels of 3% and 5% of dry matter in the diet of Saanen dairy goats influences the fatty acid profile of milk, with emphasis on linoleic acid until the 11th week of lactation.
