Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Young, female nutrias (<italic>n</italic> = 13) were fed a diet supplemented with 0.36 mg/kg selenium in selenium‐enriched yeast (SeY; Sel‐Plex; Alltech, Inc., Nicholasville, KY) for 60 days (total Se concentration in the basal diet was ∼0.1 mg/kg). Concentrations of fatty acids (FA) in the liver were compared to those of nutrias on a control diet (<italic>n</italic> = 11). Animals were sacrificed at 8 months of age and liver samples (approximately 30 g) were collected. The gas‐chromatographic analysis of tissue samples from the experimental group revealed a significant decrease in saturated fatty acids (<italic>p</italic>&lt;0.001), monounsaturated fatty acid (<italic>p</italic> = 0.006), and polyunsaturated fatty acid (PUFA) (<italic>p</italic> = 0.02) compared to controls. The linoleic and linolenic acids, which are precursors of <italic>n</italic>‐6 and <italic>n</italic>‐3 PUFA, respectively, were significantly lower (<italic>p</italic> = 0.01 and <italic>p</italic>&lt;0.001, respectively) in the supplemented group. The <italic>n</italic>‐6 to <italic>n</italic>‐3 PUFA ratio was significantly affected (<italic>p</italic> = 0.001) by the SeY dietary supplement (13.17 vs. 8.93, respectively).</p> </abstract>
