Figure 1.
Effect of different diets on ruminal pH of dairy cows. LCF is low-concentrate mixed forage diet with a concentrate to roughage ratio of 46 : 54; HCS is high-concentrate corn straw diet with a concentrate to roughage ratio of 65 : 35; LCS is low-concentrate corn straw diet with the same concentrate to roughage ratio (46 : 54) as LCF. A-BMeans between treatments differ (P < 0.01).
