Zusammenfassung:Summary To clarify the influence of feeding of dried soybean curd residue on the milk production and nutritional status in early to mid lactation stage, eight multiparuos cows were assigned to one of two diets which contained dried soybean curd residue 12% in dry matter (group T) or not contain6d (group C). The following results were obtained: (1) There was no significantly difference in dry matter intake, total digestible nutrient (TDN) intake and TDN sufficiency for Japanease Feeding Standard between the two groups during the experimental period. (2) There was no significantly difference in milk yield between the two groups. (3) Milk fat content was significantly lower for group T than group C at 1 to 3 month of postpartum. The concentration of Milk Uera Nitrogen was significantly higher for group T than group C at 1 and 4 month of postpartum. (4) The degree of decreasing of body weight and body condition score in postpartum were less, and recovering earler for group T than group C. There was significantly difference in the loss of body weight at 1 month of postpartum. (5) In the rumen fluid character, the molar percent of acetic acid were significantly lower at l and 4 month of postpartum, and the concentration of ammonium nitrogen were significantly higher at month of postpartum for group T than group C.(6) In the blood metabolism, there were nothing nutritional disorder, thogh there were significantly difference in some item at one time. The results of the present study suggest that it is required the adequate ingredient of diets to prevent reduction of milk fat content in the feeding of dried soybean curd residue.
