Grassland Oregon (www.sucraseed.com) mixes of either alfalfa or red clover.
"This is a significant improvement in silage," says Jerry Hall, research director for Grassland Oregon. "Recent studies by the US Department of Agriculture show that red clover performs
better than alfalfa, and by introducing high-sugar grasses to the mix, we're able to further increase the silage performance."
The improvements are due to the presence of high-sugar grasses. In a study performed in the UK, it was shown that the efficiency of incorporation of silage Nitrogen (N) into microbial N
was more than 20% greater in high-sugar grass than for the control grass silage. A mix containing high-sugar grass and red clover increased the efficiency of N use by greater than 40%
compared with red clover silage. Ensiling high-sugar grasses results in silage with greater residual water-soluble carbohydrate content (Davies et al., 2002).
Water-soluble carbohydrates (WSC) provide the energy needed for fermentation. By incorporating high-sugar grasses into the silage (
