Figure 4.

Interaction of treatment (TRT) and temperature (TEMP) on the predicted ME and comparison of predicted ME by the in vitro gas production technique (IVGP) and the direct measure ME of steers 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% RH) or heat stressed (HS; 35 ± 0.55 °C; 42% RH). Contrasts of TN and HS (red) are included to denote possible effect of TEMP on passage rate and accuracy of IVGP prediction.
