Perfil de acidos grasos de barbacoa de borregos pelibuey

The objective of this study was to evaluate the fatty acids profile in Pelibuey sheep barbacoa complemented with protected conjugated linoleic acid. Samples of the Longissimus dorsi muscle were used, from 24 Pelibuey sheep which were housed in groups of six animals. Each group was assigned randomly to apply the treatments: 1) base diet with 0, 2) 25, 3) 50, and 4) 75 g of protected conjugated linoleic acid (ALCp) animal1 d1. A completely random design was used, using the PROC GLM and Tukey test for means comparison. Additionally, polynomials and orthogonal contrasts were used. The Tukey test didn’t show significant differences between treatments, but the orthogonal contrasts evidenced that adding protected conjugated linoleic acid to the sheep’s diet increases the cis-9, trans-11 isomer content, but that the saturated fatty acids tend to increase and the mono-unsaturated to decrease.
