Abstract
Condensed liquid made from shochu distiller grains (rice, barley, and sweet potato) were compared with regard to fermentation quality and dry matter recovery of the fermented total mixed ration (TMR). The materials' buffering capacity and volatile basic nitrogen increased and pH decreased by mixture of condensed liquids. During storage, the silage temperature increased immediately after ensiling. Subsequently, it peaked on day 4 after ensiling in the control. Although the temperature of the condensed liquid mixture TMR changed more than the ambient temperature did, the increase was gradual and almost constant. Regarding the fermentation quality of fermented TMR, the pH of the rice and barley condensed liquid portions was lower and the lactic acid content tended to be higher than in the control. In contrast, the lactic acid content was lower and C2+C3 content was higher in the sweet potato condensed liquid portion than in the control. Results show that Flieg's score of the sweet potato condensed liquid portion was lower than that of the control. The dry matter recovery rates were higher in the rice and barley condensed liquid portions than that of the control, although it was low in the sweet potato condensed liquid portion.
