Abstract: 
Effect of replacing alfalfa hay with wheat straw in iso-fibrous (35% NDF) diets with different levels of dietary cation-anion balance (DCAB) was studied by using eight mid-lactation Holstein cows blocked according to parity and milk yield in a 4x4 replicated Latin Square design. The treatments were 1) alfalfa hay (AH) with +35 meq, 2) wheat straw (WS) with +35 meq, 3) WS with +45 meq, and 4) WS with +55 meq (Na` + K+)CI-11t10 g diet dry matter (DM). Treatment periods were 15 d with the first 10 d serving as an adaptation period. Forage to concentrate ratio decreased from 43:57 to 26:74 when WS was substituted for AH. Apparent digestibility of DM, organic matter (OM), and nitrogen (N), and DM disappearance rate at 24 h post-feeding decreased significantly in WS containing rations (P<0.01), but was not increased with increasing dietary cation-anion balance (DCAB) in WS rations. No significant differences were observed in DM intake. Actual milk yield and 4% fat-corrected milk (FCM) were not affected by the treatment. Milk fat percentage was significantly (P
