Effect of addition of Chestnut tannin (CWT) or Stevia rebaudiana Bertoni (SB) extracts to a control (CTR) substrate (dry total mixed ration) on total protozoal counts during the days of fermentation in a continuous rumen fermenter (Exp. 2). (Treatment means of CTR and CT (86.3 × 103 and 76.2 × 103 cell/mL, respectively) differ (P < 0.05) from SB mean (66.7 × 103 cell/mL, standard error of the treatment means is 4.65 × 103 cell/mL); interaction effect of fermentation day × treatment was not significant; means of days under the horizontal asterisk lines are not significantly different; standard error of the fermentation day means: 8.06 × 103 cell/mL).
