Fats are key components in animal nutrition for maintaining normal development and performance. They are organic, water-insoluble substances and are classified as saturated (SFA), unsaturated (USFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acids (1). The level of inclusion in the diet affects animal growth and feed conversion. The inclusion of fats in the diet differs in monogastric and polygastric animals as it is related to lipid metabolism. In ruminants, dietary fats are hydrogenated in the rumen before intestinal absorption, for this reason, absorbed fatty acids are more saturated than fatty acids supplied by the original diet. In contrast, in non-ruminants, the intestinal digestibility of fatty acids depends on the degree of saturation of these fatty acids supplied in the diet (2).
