Probióticos en pollos parrilleros: una estrategia para los modelos productivos intensivos

Abstract

ResumenLa industria avícola se ha convertido en una importante actividad económica en Argentina. En nuestro país, el consumo de carne aviar ha experimentado un aumento sustancial en los últimos años debido al incremento y a la diversificación de la oferta de productos. Gracias a los avances tecnológicos experimentados en los últimos años (mejoras genéticas, automatizaciones, planes sanitarios, etc.), el pollo parrillero alcanza en solo 50 días el peso requerido para la faena, con 2,7kg y una conversión alimentaria de alrededor de 1,6kg de alimento/kg de carne. Para satisfacer la demanda actual y continuar en la búsqueda de mercados internacionales, los pollos parrilleros son sometidos a sistemas de crianza intensivos en confinamiento. En esos sistemas, los pollos parrilleros están expuestos diariamente a diversos factores de estrés. La suplementación con antibióticos fue ampliamente utilizada en las últimas décadas para estabilizar la microbiota intestinal, mejorar los parámetros productivos y prevenir las enfermedades aviares. Sin embargo, la utilidad de esta estrategia ha sido cuestionada debido a la aparición y propagación de bacterias resistentes a los antibióticos en la carne. Por lo tanto, hay un renovado interés en la búsqueda de alternativas viables a los antibióticos; es así que la suplementación de las dietas con probióticos se plantea como una opción interesante. Esta revisión proporciona un resumen actual sobre el empleo de probióticos en pollos parrilleros, haciendo énfasis en el papel de estos como una terapia alternativa que podría reemplazar a los antibióticos utilizados en producción y sanidad animal.AbstractThe broiler industry has become an important economic activity in Argentina. Global production of broiler meat has been growing in Argentina faster than for any other meats, possibly due to declining poultry prices and increasing incomes. Modern rearing systems can produce broilers ready to slaughter in 50 days, with the required 2.7kg of weight and a feed conversion of about 1.6kg feed/kg of meat. Nevertheless, broilers raised under these intensive conditions are exposed to various stressors every day. For many years, feed supplementation with antibiotics was widely used to stabilize the gut flora, improve general parameters and prevent avian diseases. However, the utility of antibiotics has been questioned because of the emergence and spread of antibiotic-resistant bacteria in meat. Therefore, there is a renewed interest in finding viable alternatives to antibiotics. One potential method is the supplementation of broiler diets with probiotics. This review provides an updated summary of the use of probiotics to improve sanitary conditions and enhance performance in broilers, demonstrating the role of probiotics as a reliable option to replace antimicrobial growth promoters.
