Abstract

Recent studies have shown that increasing dietary crude protein (CP) prepartum above National Research Council (NRC) (1989) recommendations does not influence multiparous dairy cow performance. To evaluate the effect of prepartum dietary CP level on performance during early lactation, 64 multiparous Holstein cows were utilized in a randomized complete block design
