Characterization of whole plant corn silage harvested at different cutting heights and with two openings of the grain conditioner in field conditions
Maize was harvested for whole plant silage at two cutting heights (CH) above the ground, 30cm (CH30) and 55 cm (CH55), and with two grain conditioner roller openings (RO), 1mm (RO1) and 3 mm (RO3). The amount of dry matter of the remaining material (DM) and its dry matter percentage (%DM) at both CH...

The amount of dry matter of the remaining material (DM) and its dry matter percentage (%DM) at both CH was determined. In a bifactorial design, the CH*OR treatments were analyzed for their kernel processing scores (KPS) on the harvested material, and chemicalcomposition and in situ ruminal degradation of starch (DegS) in micro-silage. Plots harvested at CH55 had a larger DM and showed a tendency to present higher %DM and higher %DM in the ensiled material compared to CH30. In themicro-silage, there were some differences in the contents of neutral detergent fiber and of lignin in acid detergent, for both variables the lowest value was presented by the combination CH55-RO3. Both the KPS of the ensiled material and DegS were similar among all treatments. The KPS value indicates minimal processing under the field conditions. Un cultivo de maíz destinado a la confección de silaje de planta entera, se cosechó a dos alturas de corte (AC), 30 cm (AC30) y 55 cm (AC55) desde el suelo, y con dos aperturas de los rodillos (AR) del acondicionador de granos, 1 mm (AR1) y 3 mm (AR3). Se estimó la cantidad de materia seca por unidad de superficie (MS) del remanente y su porcentaje de materia seca (%MS) para las diferentes AC. Para los tratamientos AC*AR, definidos en un diseño bifactorial, se evaluó el índice de procesado del grano (IPG) del material a ensilar, y composición química y degradación ruminal in situ del almidón (DegA) de silajes confeccionados en microsilos. En AC55 el remanente tuvo mayor MS y una tendencia a presentar mayor %MS, y el material de los microsilos tuvo mayor %MS en relación a AC30. En la composición química de los microsilos, sólo el contenido de fibra detergente neutro y de lignina en detergente ácido mostraron diferencias, los menores valores los presentó la combinación de AC55-AR3. Para IPG y DegA, los tratamientos no fueron diferentes. El valor de IPG refleja un bajo nivel de procesamiento en las condiciones de campo en las que se trabajó.
