Figure 2.

Representation of the mean diurnal fluctuation of ruminal pH (A) and ruminal temperature (B) over 48 h consuming a finishing diet. Treatments were control diet (CON) or control diet + 3 g/d of an active dried yeast (ADY). Temperatures were thermoneutral [TN; 18 ± 0.55 °C; 20% relative humidity (RH)] or heat stressed (HS; 35 ± 0.55 °C; 42% RH). Interaction of TRT and red arrows indicate feeding events. The mean pH represents the average of 8 replications per treatment combination, respectively over 48 h at 10-min intervals.
