Holstein cows in early lactation, producing about 30 kg/d of milk, were fed high energy diets containing 5% Megalac. Three protein treatments, soybean meal diet (16% CP), fish meal diet (16% CP), and soybean meal-fish meal diet (20% CP) were compared

Two fistulated, nonlactating Holstein cows were fed a high quality diet of dairy concentrate mixed with corn silage or a low quality diet of weathered hay. Both animals were adapted in turn for 6 wk to the high quality and then to the low quality die

Four rumen-fistulated cows were fed alfalfa hay (15.4% CP) ad libitum for 4 wk prior to the experiment and from day 1 to day 8 of the experiment. From days 9 to 15 (period 2) and from days 16 to 39 (period 3) they were fed ad libitum concentrate: ure

A total of 41 multiparous Holstein cows were randomly allocated, prepartum, to one of five diets. Diets were (1) a negative control consisting of 15.5% soybean meal (SBM) concentrate plus control corn silage (CS) (12.6% crude protein, (CP)); (2) 33.5

In two experiments, lactating cows (26 in exp. 1; 32 in exp. 2) were fed an 11.3% crude protein (CP) diet, a 14.7% CP diet containing untreated soybean meal (SBM) or a 14.6% CP diet containing formaldehyde-treated SBM (FSBM), all three fed as a compl
