To determine the possibility of obtaining goat milk with a high dietetic quality, an experiment was carried out using two groups of goats. Animals were fed with either a diet supplemented (9 per cent) or not supplemented (0 per cent) with a protected fat rich in polyunsaturated fatty acids (PUFA). These diets were completed diets, pelletted and administered in this way together with a long fiber food, cereal straw. Feed intake was lower for goats fed the supplemented diet. Type of diet had no effect on milk production. However milk dry matter (DM) and fat contents were higher for goats fed the diet supplemented with the protected fat whereas protein content was lower. Type of diet affected fatty acid composition of the milk fat. Thus, the percentages of monounsaturated and polyunsaturated fatty acids in milk fat were higher for goats fed the diet supplemented with the fat. It is concluded that the use of protected fats rich in PUFA may be an appropriate strategy to improve the healthy quality of goat milk
