Fats are excellent sources of energy for pig feeding. The objective of this work was to analyze the levels of fatty acids in meat of pigs fed with diets including cassava flour, corn ground, and expeller soybean, supplemented with fish oil. Four pigs were used in three repetitions per treatment. The assay was carried out using a completely randomized design during 21 days (7 days for adaptation and 14 days for determinations). The experience included 4 diets; T1: basal diet (DB) prepared with ground corn (66%) plus soybean expeller (31%), T2: DB + fish oil 5% (by weight), T3: DB with 40% corn replaced by integral cassava (DBM) and T4 = DBM + fish oil 5% (by weight). Descriptive statistics and analysis of variance were performed by one-way, where the null hypothesis was rejected with an a risk level of 5%. Means were compared using the Tukey's test. Treatment averages did not show significant differences for saturated, mono-unsaturated nor poly-unsaturated fatty acids. It can be concluded that fish oil in pig diets does not cause changes in fatty acid meat profile.
