Three experiments were conducted to examine the fermentation process and the effect of some pre-ensiling treatments on quality and palatability of napiergrass (Pennisetum purpureum Schumach). The grass were harvested four times per year at ten weeks interval and were ensiled in laboratory silos after the following treatments: 1) Sample with no treatment (control), 2) Wilting for 2 to 3 hours (wilting) and 3) Addition of molasses at the rate of 3-9% as silage additive (molasses) in both experiment 1 and 2. In experiment 3, the grasses were harvested four times per year at eight weeks interval and were ensiled in laboratory silos after the following treatments: 1) Sample with no treatment (control), 2) Wilting for 2 to 3 hours (wilting), 3) Inclusion of beet pulp at up to 5% (beet pulp), 4) Inclusion of bagasse at up to 5% (bagasse) and 5) Inclusion of citrus pulp at up to 5% (citrus pulp) as an additive to control water and available carbohydrate content. The fermentative quality of treated silage was either same or higher as compared with the control. The ratio of lactic acid content to total organic acids of the respective silage was increased by these pre-ensiling treatment. The lactic acid content especially was increased to over 10% on average and pH also decreased to under 4.0 in both molasses and citrus pulp treated pulp silages.
