Summary

Sugar cane and maize silage samples were evaluated by the semi automated in vitro gas production technique. The associations between gas production and dry matter degradation (DMD) were analysed and high coefficients of determination were obtained for all the substrates. The results showed that particles losses could be influencing the DMD, including errors mostly when obtained before 6 hours of incubation. The gas alone could better predict the lag phase than the DMD before 6 hours of incubation.

Resumen

Resumen

Muestras de caña de azucar y ensilado de maíz fueron evaluados con el método semi automatizado de producción de gas in vitro. Se analizó la correlación entre la producción de gas y la degradación de la materia seca (DMS) obteniendose un alto coeficiente de determinación en todos los casos. Los resultados muestran que la pérdida de partícula puede influir sobre la DMS. Los errores por esta causa ocurrieron generalmente antes de las seis primeras horas de incubación. La producción de gas por si sola podría predecir la fase de retraso (lag) de la fermentación de una mejor manera que la DMS en el lapso de las 6 primeras horas de incubación.
