Abstract
Eight primiparous and nine multiparous Holstein cows were used in a randomized block design to determine the effect of wet corn gluten feed in the diet during the last 21 days of gestation on dry matter intake and early postpartum performance. Multilactation cows fed wet corn gluten feed maintained a higher dry matter intake and intake as a percentage of body weight during the last week before calving than cows fed the control diet. First-lactation cows fed wet corn gluten feed consumed less dry matter, both total and as a percentage of body weight, across calving than first-lactation cows fed the control diet. Milk, milk components, and blood metabolites were not influenced by diet. Wet corn gluten feed may help alleviate the depression in intake typically observed during late gestation for multiparous but not primiparous cows.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Summary
The 30% decrease in dry matter (DM) intake often observed in dairy cows during the last week before calving is of interest, because it appears to be associated with an increase in body fat mobilization, the onset of fatty liver, and a lower DM intake after calving. Wet corn gluten feed (WCGF) increased DM intake and milk yield in two lactatingcow studies at Kansas State University. The observed improvement in intake may have been due partially to an increase in dietary fiber digestibility and a positive effect on ruminal pH as reported by others. If this is the case, its inclusion in close-up diets might reduce the severity of the observed prepartum intake depression and enhance DM intake immediately after calving. Our objective was to evaluate the effect of wet corn gluten feed on DM intake and performance of dairy cows during the periparturient period
