The effects of cottonseed and sunflower oil supplementation on milk composition were tested using crossbred Moxotó goats. Experimental diets were as follows: control, without addition of oil; addition of 3% cottonseed oil; 5% cottonseed oil; 3% sunflower oil and 5% sunflower oil (%DM). Ten confined lactating goats were allotted to a double Latin square experimental design (5 × 5). Each period was comprised by 12 days of adaptation to the diet and three days of sampling in each period. Cottonseed oil supplementation at 5 %DM increased the fat content (4.99%) and the total solid (13.48%) of milk. However, the addition of sunflower oil at 5% promoted an increase in the linolenic acid (C18:3) concentrations. Therefore, the vegetal oil addition in diets for native goats promoted an increase in the percentage of milk fat and in unsaturated fatty acid contents in milk, resulting in a product of better quality for the human health.
