Abstract

This study was conducted from April 2013 to September 2013 at the School of Sustainable Agriculture (SSA), Universiti Malaysia Sabah. This study was carried out to determine the biomass yield and chemical composition of three forage species. The effect of effective microorganism activated solution (EMAS) towards the quality of the silage produced from the three forages was also assessed in this study. The treatment in this study was three forage species that were Guinea grass, Splendida grass and Signal grass. For silage production there were two treatments which were the control treatment and silage with 0.001% EMAS. Each treatment consisted of three replications. The experimental design used was Completely Randomized Design (CRD) and the data for biomass yield and chemical composition was analysed using one way ANOVA and the data for silage quality was analysed using two way ANOVA both at 0.05% significance level. No significant differences (p>0.05) were observed in fresh yield, DM yield, CP yield as well as OM, Ash contents among the three forages. However, the DM content in Splendida grass was significantly higher (p<0.05) compared to the other two grasses. The CP and EE content in Signal grass was significantly lower (p<0.05) when compared to the other two forages. The CF content in Guinea grass however was significantly higher (p<0.05) than the other two grasses. There was a significant difference (p<0.05) in the nitrogen free extract content among the three forages with Signal grass containing the highest amount followed by Splendida grass and Guinea grass. In terms of silage quality, there was no significant difference (p>0.05) between the two silage treatments. However, there was a significant difference (p<0.05) in the silage quality among forage species. In the control treatment, the pH of Guinea grass was significantly higher (p<0.05) compared to the other two forages which had no significant difference among each other. In the treatment with 0.001% EMAS, the pH of Signal grass was Significantly higher (p<0.05) compared to the other two forages which had no significant difference among each other. It was concluded that Guinea grass was better than Splendida grass and Signal grass on the basis of DM yield, CP yield and overall chemical composition. In addition, the usage of effective microorganism activated solution was also not effective in improving the silage quality. Further research is needed however, to investigate the lactic acid content to understand the type of fermentation microorganism which dominated the fermentation, the effect of water soluble carbohydrate content on silage quality and the performance of the animals when fed silage produced from EMAS.
