15 multiparous Holstein cows kept at the Ibaraki Prefectural Animal Experiment Station in Japan were given diets containing soyabean meal (SBM) or fish meal (FM) from 4 weeks before expected calving date to 20 weeks post partum. During the pre- and postpartum period diets were formulated to contain 4 and 7.5% SBM or 2.5 and 5% FM. Each diet was formulated to contain similar amounts of CP, ADF, and NDF.
