Importancia del tamaño de partícula y el uso de inoculante en ensilajes
Importance of particle size and use of bacteria in inoculant silages
Contenido principal del artículo
Resumen
El objetivo de la presente revisión es discutir sobre la importancia del ajuste adecuado del tamaño de partícula en el momento de la colecta de la planta de maíz al ser ensilada y del uso o no de inoculante bacteriano. Los ensilajes han sido ampliamente utilizados por los ganaderos por exigir tecnologías simples y presentar resultados satisfactorios, ya que esta tecnología de conservación es menos dependiente de factores climáticos, en comparación al heno. El tamaño de corte de las partículas puede causar modificaciones en la fermentación de la masa ensilada, a través de diferentes densidades obtenidas en el silo, lo que a su vez puede provocar modificaciones en la actividad masticatoria e en el desempeño de los rumiantes. La fermentación en el silo es un proceso complejo y dinámico que es afectado por una gran variedad de factores inherentes al manejo, por eso, se ha intensificado el uso de inoculantes bacterianos para acelerar la fermentación del forraje y disminuir las pérdidas durante el proceso de descargue. Todavía existe un gran espacio para investigar sobre los verdaderos efectos del ajuste en el tamaño de partícula asociada al uso de inoculantes bacterianos, tanto en lo que se refiere al ambiente del silo como al desempeño animal.
