Modification of the content of n-3 highly unsaturated fatty acid, chemical composition, and lipid nutritional indices in the meat of grass carp (Ctenopharyngodon idella) fed alfalfa (Medicago sativa) pellets
A 120-d feeding trial was conducted to determine the effect of alfalfa (Medicago sativa) feeding on growth and chemical composition, fatty acid content, and nutritional and lipid indices of the meat of grass carp (Ctenopharyngodon idella). Two experimental diets were used: alfalfa pellet (AP) diet a...

| description | A 120-d feeding trial was conducted to determine the effect of alfalfa (Medicago sativa) feeding on growth and chemical composition, fatty acid content, and nutritional and lipid indices of the meat of grass carp (Ctenopharyngodon idella). Two experimental diets were used: alfalfa pellet (AP) diet and artificial grain diet (GD). Final weight, feed conversion rate, and protein efficiency ratio were significantly greater in the GD group (P < 0.05). However, no differences in the length and condition factor were observed. The composition of the meat differed between treatments. The protein content was significantly greater in the AP group (P < 0.05), while the lipid and cholesterol contents were significantly greater in the GD group (P < 0.05). A greater proportion of saturated, n-6 polyunsaturated, and n-6 highly unsaturated fatty acids was obtained in the GD group. The AP group accumulated a greater concentration of eicosapentaenoic (EPA), docosapentaenoic (DPA), and docosahexaenoic (DHA) acids (P < 0.05). The fatty acid composition of the meat determined a significant decrease in the thrombogenicity index and saturation index (S/P) in the AP group (P < 0.05). The Elongase index was greater in the GD group (P < 0.05). In contrast, the AP group had a greater index of Δ9 Desaturase and Δ5 + Δ6 Desaturase for n-3 and n-6 fatty acids (P < 0.05). These results suggest that alfalfa feeding decreases the growth of C. idella but improves the quality of meat by increasing the protein, EPA, and DHA contents. It also reduces cholesterol content and improves nutritional indices. |

Se realizó una prueba de alimentación de 120 días para determinar el efecto de la alimentación con alfalfa (Medicago sativa) sobre el crecimiento y la química composición, contenido de ácidos grasos e índices nutricionales y lipídicos de la carne de carpa herbívora (Ctenopharyngodon idella). Se utilizaron 2 dietas experimentales: dieta de gránulos de alfalfa (AP) y dieta de granos artificiales (GD). Peso final, tasa de conversión alimenticia, y la relación de eficiencia proteica fueron significativamente mayores en el grupo GD (P < 0,05). Sin embargo, no hay diferencias en la longitud y factor de condición fueron observados. La composición de la carne difirió entre tratamientos. El contenido de proteína fue significativamente mayor en el grupo AP (P < 0,05), mientras que los contenidos de lípidos y colesterol fueron significativamente mayores en el grupo GD grupo (P < 0,05). Se obtuvo una mayor proporción de ácidos grasos saturados, poliinsaturados n-6 y muy insaturados n-6 en el grupo GD. El grupo AP acumuló una mayor concentración de eicosapentaenoico (EPA), docosapentaenoico (DPA) y ácidos docosahexaenoicos (DHA) (P < 0,05). La composición de ácidos grasos de la carne determinó una disminución significativa en la índice de trombogenicidad e índice de saturación (S/P) en el grupo AP (P < 0,05). El índice de Elongasa fue mayor en el grupo GD (P<0,05). En cambio, el grupo AP tuvo mayor índice de Δ9 Desaturasa y Δ5 + Δ6 Desaturasa para los ácidos grasos n-3 y n-6 (P<0,05). Estos resultados sugieren que la alimentación con alfalfa disminuye el crecimiento de C. idella pero mejora la calidad de la carne al aumentando los contenidos de proteína, EPA y DHA. También reduce el contenido de colesterol y mejora los índices nutricionales. Instituto de Investigación de Tecnología de Alimentos (ITA) Fil: Montenegro, Luciano Federico.
