Abstract
The objective of this study was to obtain the basic information on the development of fermented total mixed ration (TMR) including malt whisky distillery byproducts for fattening cattle. Fermented TMR consisted of barley distillers grains (BDG), barley distillers solubles (BDS), rice straw, sugar beet pulp and molasses was prepared to determine its fermentation quality, animal preference and nutritive value. Laboratory ensiling method using a plastic pouch for packing was applied to compare the fermentative quality among four treatments: a mixture of 50％ BDG and 50％ BDS in a FM basis (BDG・BDS), a mixture of 40％ BDG and 60％ BDS (BDS60), BDG・BDS with lactic acid bacterial inoculant (BDG・BDS・LAB) and BDS60 with the bacterial inoculant (BDS60・LAB). Flieg score (99 points) of the fermented TMR in the BDS60・LAB pouch was significantly higher than those of other treatments (P＜0.05), suggesting that the quality was much superior to others. The intake rate of the BDS60・LAB by fattening steers increased day by day after feeding, and the average intake rate reached about 80％ on the 3rd day. Thus, it was shown that the animals preferred the BDS60・LAB. Crude protein content and total digestible nutrients of the BDS60・LAB were 15.1 and 68.5％, respectively. In conclusion, malt whisky distillery byproducts prepared by 50％increase of BDS in a mixture of BDG and BDS, rice straw, sugar beet pulp and molasses ensiled with LAB can cause excellent fermentative quality, and relatively higher palatability and nutritive value.
