Diurnal pattern of ruminal pH in beef cattle fed high-grain diets supplemented with different levels of fumaric acid (low fumaric acid [LF], 61 g/d, and high fumaric acid [HF], 125 g/d) or malic acid (low malic acid [LM], 59 g/d, and high malic acid [HM], 134 g/d). The position of the arrow indicates the time of feeding, that is, 1000 h.
