Fecal pH following transitions between cool-season and warm-season grass. Fecal pH of horses across six days following transitions from cool-season to warm-season grass (C–W) and warm-season to cool-season grass (W–C) in both the bermudagrass integrated rotational grazing system and the crabgrass integrated system. There was an effect of transition and grazing system (mixed model ANOVA with Tukey’s post hoc adjustment; P ≤ 0.02), but pH did not differ by day. There were no significant interactions between main effects
