Nutrient Parameters of Grass Silages

Abstract

The set of samples was classified by the phenophases: before the heading, the beginning of heading and full heading. Each group contained 12 samples. The parameters of nutritional value were evaluated. The chemical compositions (CP, PDIN and DOM) were highly significantly affected (P < 0.01) by the phenophases. The best results have been reported in grass silage harvested in the phenophase before the heading. The chemical compositions CF and NEL were better (P < 0.01) in grass silages harvested in the phenophase before the heading and in the phenophase the beginning of heading against grass silage harvested in the phenophase full heading.
