"We carriedout several experiment to imprave the productivity of milk by utilizing draffy matter of Soybean curd. We tried to prepare the silage by the use of draff of Soybean curd alone and with or without adding agents and fed dairy cows with fodder prepared silage. Furthermore the deradation patterns of fed protein in the rumen were also examined by a nylon-bag method. The draff of bean curd is liable to conupt due to its high water content, although it is one of the most nourishing fodder. Then,the rise of temperature was under various conditions, and no recoguizable efficacy was found by adding any agents to draff of Soybean card after preparing Total Mixed Ration (TMR). It is rather of importance to prevent the heat frome generating and to seae off the air by using are-tight vinyl film. The feading tests of dairy cows were eonducted under hot Summer season to examined the quality and quantity of milk produced and blood ingredients. The fodder of draffy mather of Soybean curd within the upper limit mixed with the TMR (obc-plot) was compared with those of heat-compressed Soybean and Soybean meal which substituted partially for draff of Soybean curd (control plot). In fodder intake and milk production no difference was found between both plots. Urea nitorogen levels in blood and milk for control plot were higher than for DBC-plot. Results of rumen digestion tests revealed that the digestion rates of dry matter and crude protein were a higher storoybean meal than for heat-commpresed soybean. Crude draff of Soybean curd showed the same digestion rates of dry matter and crude protein as those of the soybeanm meal but their digestion rates of the draff, when preparated silage, were similar to those of heat-pressed Soybean."
