Popis:	In two trials 57 and 44 Holstein cows were used to determine the effect of feeding wet corn gluten feed (CGF) on total dry matter (DM) intake and milk production. Treatments compared were: Trial I, control vs. wet CGF at either 18.6 or 37.1% of ration DM; Trial II, control vs. dried or wet CGF each at 26% of ration DM. Within each treatment in Trial II, cows were balanced to receive sodium bicarbonate in either the first or second half of the 10-wk experimental period. Total mixed rations were offered ad libitum. In Trial I the multiparous cows fed either level of CGF, consumed less DM and produced less actual and solids-corrected milk (SCM) than did those fed the control diet. Differences across treatments were greater in the first 4 wk. Primiparous cows showed no (P > 0.05) treatment effects. In Trial II parities were similar in response to treatment. Sodium bicarbonate did not (P > 0.05) affect performance. Milk yield was lower (P
