“…However, we do not agree with the assumption of these authors that intensively fed animals had a higher total proportion of SFA. In our study, the concentration of SFA was 35.8-38.3%, which was similar to the results of Glogowski et al (2010) who reported 33% in females and 35.1% in males with forage-based feeding. The MUFA contents were significantly higher in females than in males, which corresponded with the findings of Saadoun et al (2006) and Glogowski et al (2010).…”

“…In all colour types, the saturated fatty acids (SFA) had the highest content followed by monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA). The SFA contents were similar to those described by Glogowski et al (2010). However, we do not agree with the assumption of these authors that intensively fed animals had a higher total proportion of SFA.…”

“…Relatively more is known about nutria slaughter traits and carcass composition, as described by Faverin et al (2002), Mertin et al (2003), Cabrera et al (2007), and Glogowski and Panas (2009). Tulley et al (2000), Saadoun et al (2006), Cabrera et al (2007), Glogowski and Panas (2009), Glogowski et al (2010), and Migdal et al (2013) have all recently determined the nutritional value of nutria meat.…”

ABSTRACT:The effects of sex and colour type on carcass composition, nutrients content, and muscle fibre characteristics of hind leg meat of nutrias raised under intensive conditions were the focus of this study. Thirtysix eight-month-old nutrias of both sexes with three colour types (Standard nutria, ST; Moravian Silver, MS; and Prestice Multicolour, PM) were studied. Live weight was affected by colour type (P < 0.05) and sex (P < 0.001); however, no effects of these variables were found for the dressing out percentage. Crude protein content was significantly higher in males than in females, whereas crude fat content was higher in females. A significant interaction between colour type and sex was found for hydroxyproline and ash contents. Fatty acids were affected primarily by the sex of nutrias. No effect of colour type on the distribution of muscle fibres in the Biceps femoris muscle was found. However, females had fewer βR (P < 0.05) and more αR fibres (P < 0.001) than males.

Young, female nutrias (n ¼ 13) were fed a diet supplemented with 0.36 mg/kg selenium in seleniumenriched 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 (n ¼ 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 ( p < 0.001), monounsaturated fatty acid ( p ¼ 0.006), and polyunsaturated fatty acid (PUFA) ( p ¼ 0.02) compared to controls. The linoleic and linolenic acids, which are precursors of n-6 and n-3 PUFA, respectively, were significantly lower ( p ¼ 0.01 and p < 0.001, respectively) in the supplemented group. The n-6 to n-3 PUFA ratio was significantly affected ( p ¼ 0.001) by the SeY dietary supplement (13.17 vs. 8.93, respectively).

Ruminant diets supplemented with different sources of unsaturated fatty acids (UFA) may be effective for modulating the rumen biohydrogenation process as well as for de novo fatty acid synthesis in animal tissues. Such a supplementation may consequently improve the proportion of fatty acids in animal products. The obtained effect in animal products depends on the quantity and composition of dietary fat; particularly UFAs. This study illustrates the effect of diets in which two doses of Camelina sativa (100 and 200 g in concentrate dry matter, respectively) were given as the primary sources of UFAs. The study shows the effect on the fatty acid contents in longissimus dorsi muscle of lambs. Diets containing C. sativa led to higher contents of either C18:2 c9t11 or C18:2 t10c12 isomers in lamb muscle as well as an increase in vaccenic acid (VA), arachidonic acid (AA), eicosapentaenoic acid (EPA) and docosapentaenoic acid (DPA) contents. The results also indicated that the addition of C. sativa leads to a higher content of linoleic, oleic and alpha linolenic acids in lamb muscles. Practical applications: The results of this study showed favorable changes in the UFA contents in longissimus dorsi muscle of lambs. The changes were obtained by supplementing the diets of the lambs with C. sativa cake, the plant cultivated as a biodiesel source. Inclusion of C. sativa cake in the concentrate dry matter for lambs may allow animal products to obtain the nutritionally desired fatty acids. Consumption of enriched products may act as chemopreventive agents and counteract the development of some human diseases.
