Effect of deferred and use time on yield and quality of Megathyrsus maximus cv. Gatton panic, in semi-arid Chaco

In semi-arid Chaco, there are areas that present limitations on fodder stocks. In these situations, deferred forage is the main strategy to overcome the forage deficit. The aim of this work was to evaluate the effect of deferred and use time of Megathyrsus maximus cv. Gatton panic on yield and nutri...

Deferred forage Gatton panic yield nutritional quality Forraje diferido Gatton panic rendimiento calidad nutricional In semi-arid Chaco, there are areas that present limitations on fodder stocks. In these situations, deferred forage is the main strategy to overcome the forage deficit. The aim of this work was to evaluate the effect of deferred and use time of Megathyrsus maximus cv. Gatton panic on yield and nutritional quality. Three deferred times (February, March and April) and two use times (June and August) were evaluated. Dry matter partitioning was determined by separating leaves and stems. Through laboratory analysis, forage quality parameters such as crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were evaluated, besides dry matter digestibility (DMD) and metabolizable energy (ME) were calculated. The highest forage yield was recorded in February, although more advanced phenological development was observed, increasing NDF and FDA, and decreasing the ratio leaf/steam and the percentage of CP. There were no differences in yield between time of use, although there were differences in the percentage of CP, which was higher in June. There were also no differences for digestibility and metabolizable energy between deferred  and use time. En el Chaco semiárido hay zonas que presentan limitaciones para la confección de reservas forrajeras. En estas situaciones, el forraje diferido se constituye en la principal estrategia para superar el bache forrajero. El objetivo de este trabajo fue evaluar el efecto del momento de diferimiento y de utilización de Megathyrsus maximus cv. Gatton panic sobre el rendimiento y la calidad nutricional. Se evaluaron tres momentos de diferimiento (febrero, marzo y abril) y dos momentos de utilización del forraje (junio y agosto). Se determinó la partición de materia seca separando hojas y tallos. Mediante análisis de laboratorio se evaluaron parámetros de calidad del forraje: proteína bruta (PB), fibra detergente neutra (FDN) y fibra detergente ácida (FDA) y se calculó la digestibilidad de materia seca (DMS) y la energía metabolizable (EM). El mayor rendimiento de forraje se registró en la clausura de febrero, aunque se observó un desarrollo fenológico más avanzado, aumentando la FDN y FDA y disminuyendo la relación hoja/tallo y el porcentaje de PB. No hubo diferencias en el rendimiento entre los distintos momentos de utilización, aunque sí en el porcentaje de PB, que fue mayor en junio. Tampoco se registraron diferencias para digestibilidad y energía metabolizable entre los momentos de diferimiento y de utilización. Instituto Agrotécnico "Pedro M.
