Shochu distillery by-product cake was added to 4 varieties of roughage, and the feed composition and fermentation quality characteristics of these roughage silages were examined. Roughage used included corn silage (CS), Italian ryegrass silage (IS), forage rice silage (RWCS) and rice straw (RS), and shochu distillery by-product cake derviced from barley shochu was also used. Four varieties of roughage silage were prepared by mixing 5% or 10% of shochu distillery by-product cake in a dry matter base. The pH of CS, IS and RS, when measured 28 days after being prepared, were lower than the levels measured immediately after preparation. However, the pH of RWCS were equivalent both immediately after preparation and 28 days after preparation. The general volatile fatty acid content of all silages proved significantly higher 28 days after preparation as compared to immediately after preparation. The V-score for all silages was also good. Based on these results, we have learned that the addition of shochu distillery by-product cake to roughage rises the crude protein content, and can preserve shochu distillery by-product cake.
