The aims of this project were to establish a technique for preparing pellet feeds for cattle using shochu distiller's by-products and to evaluate the product as a feedstuff for beef cattle. Pellets were made by extrusion using a mixture of buckwheat, shochu distiller's condensed solubles and its cake (both wet) as the main material, together with smaller amounts of barley bran and beet pulp. Three pellet feeds among the thirteen prepared showed good payability, had high protein contents and normal levels of minerals. Very little amounts of vitamins A and D were detected, while vitamins E and B6 were present at almost the same concentration as in corn and grain sorghum, respectively. Six Japanese black cattle, three animals each in control and experimental groups, received for 16 months a commercial formula feed (Miyazaki Shimofuri Tokugo) as a control diet and a formula feed replacing 15% of the dry matter of the 'Miyazaki Shimofuri Tokugo' with the pellet feed as an experimental diet. The experimental diet contained the same levels of TDN and CP as those of the control diet. No differences in body weight gains or feed conversion were detected for the first 10 months ; thereafter, up to more than 27 months after birth, animals supplied with experimental diets showed higher daily gains and lower feed conversion (higher feed efficiency) than those observed in control animals. However, there have been almost no differences in meat quality between the control and the experimental cattle as a whole, although alpha-tocopherol content in rib eye of the experimental cattle was higher than that of the control. Total lipid content in of the control animal was higher than that of the experimental animal.
