Effect of slaughter age on the fatty acid profile of Celta pig breed

espanolEl cerdo Celta es una raza autoctona del noroeste de Espana, caracterizada por su rusticidad y su adaptacion a las condiciones ambientales, por lo que pueden ser criados en regimen extensivo y semi-extensivo. Se estudio el efecto de la edad de sacrificio (12, 14 y 16 meses) en el perfil de acidos grasos del cerdo Celta. Para este estudio fue usado el musculo longissimus dorsi de 45 machos castrados del genotipo Carballina. El analisis estadistico revela que los acidos grasos mas abundantes fueron los monoinsaturados, los cuales no mostraron diferencias (P>0.05) entre las edades de sacrificio. El contenido en acidos grasos saturados incremento (P EnglishThe Celta pig is an autochthonous breed from the NW of Spain, characterized by its rusticity and its adaptation to the environment, so these animals can be reared in extensive and semi-extensive regimen. The effect of slaughter age (12, 14 and 16 months) on the fatty acid profile of Celta pig breed was studied. For this study, the longissimus dorsi muscle from 45 barrows of Carballina genotype was assessed. Statistical analysis displayed that the fatty acids most abundant were the monounsaturated fatty acids, which did not show significant (P>0.05) differences among slaughter ages. On the other hand, the saturated fatty acids content significantly (P
