El \u00e9nfasis mundial en la sostenibilidad y el bienestar de los animales est\u00e1 impulsando mejoras adicionales en todos los \u00e1mbitos, desde ingredientes para piensos de origen m\u00e1s responsable hasta pr\u00e1cticas de producci\u00f3n mejoradas.&nbsp;<\/p>\n\n\n\n<p>El selenio (Se) es un oligoelemento esencial que desempe\u00f1a un papel fundamental en la regulaci\u00f3n de las defensas antioxidantes tanto en peces como en humanos. Adem\u00e1s, se ha demostrado que la suplementaci\u00f3n de los piensos para peces con Se org\u00e1nico aumenta el contenido de Se en el m\u00fasculo y mejora los rasgos de calidad.&nbsp;<\/p>\n\n\n\n<p>Sin embargo, se han promulgado normas estrictas para el Se en los piensos de acuicultura, y Europa ha establecido un estricto l\u00edmite superior de 0,2 ppm para la suplementaci\u00f3n con Se org\u00e1nico. Estas normativas suponen un reto importante para los nutricionistas, especialmente en el contexto de las dietas reducidas en harina de pescado, con un mayor uso de ingredientes con un contenido pobre o limitado de Se. Este art\u00edculo explora las ventajas de Zinpro<sup>\u00ae<\/sup> Disponible en<sup>\u00ae<\/sup> Selenio sobre otras fuentes, arrojando luz sobre los beneficios que puede aportar a la industria acu\u00edcola.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-oxidative-stress-a-permanent-threat-to-fish-health-and-wellbeing\">El estr\u00e9s oxidativo, una amenaza permanente para la salud y el bienestar de los peces<\/h2>\n\n\n\n<p>El estr\u00e9s se refiere a la respuesta del animal a cualquier desaf\u00edo f\u00edsico, qu\u00edmico o ambiental, desencadenado por diversos factores. El estr\u00e9s puede ser agudo (a corto plazo) o cr\u00f3nico (a largo plazo) y dar lugar a diferentes respuestas fisiol\u00f3gicas y conductuales, que son naturales y necesarias para que los animales se adapten a los cambios ambientales y los afronten.&nbsp;&nbsp;<\/p>\n\n\n\n<p>El estr\u00e9s oxidativo se produce a nivel celular y est\u00e1 causado por un desequilibrio entre la producci\u00f3n de especies reactivas del ox\u00edgeno (ROS) y la capacidad del organismo para neutralizar o desintoxicar estas mol\u00e9culas. Las ROS son muy reactivas y pueden da\u00f1ar los componentes celulares, como el ADN, las prote\u00ednas y los l\u00edpidos. El estr\u00e9s oxidativo tiene varias consecuencias negativas:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Crecimiento y rendimiento:<\/strong> escasa conversi\u00f3n alimenticia y menor ganancia de peso, lo que repercute negativamente en la rentabilidad.&nbsp;&nbsp;<\/li>\n\n\n\n<li><strong>Susceptibilidad a las enfermedades:<\/strong> Inmunidad debilitada, mayor vulnerabilidad a los par\u00e1sitos y bacterias pat\u00f3genas con mayores tasas de mortalidad.&nbsp;&nbsp;<\/li>\n\n\n\n<li><strong>Da\u00f1os en tejidos y \u00f3rganos:<\/strong> da\u00f1os en los componentes celulares con perturbaci\u00f3n de las funciones fisiol\u00f3gicas, como la osmorregulaci\u00f3n.&nbsp;<\/li>\n\n\n\n<li><strong>Deterioro de la reproducci\u00f3n:<\/strong> mala calidad de los \u00f3vulos y espermatozoides, desarrollo embrionario y menor supervivencia de las fases larvarias.&nbsp;<\/li>\n\n\n\n<li><strong>Impacto negativo en los indicadores de sostenibilidad:<\/strong> Reducci\u00f3n del bienestar animal y aumento de la huella alimentaria.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-harnessing-selenium-nutrition-to-boost-fish-strength\">Aprovechar la nutrici\u00f3n con selenio para aumentar la fuerza del pescado<\/h2>\n\n\n\n<p>El selenio es un elemento clave de importantes selenoprote\u00ednas, como la glutati\u00f3n peroxidasa, que protegen al organismo del estr\u00e9s oxidativo.
