Table 1 Effects of a Saccharomyces cerevisiae fermentation product (SCFP) and a subacute ruminal acidosis (SARA) challenge on richness and diversity indices of rumen bacterial communities calculated from 16S rRNA gene sequencing

From: Saccharomyces cerevisiae fermentation products (SCFP) stabilize the ruminal microbiota of lactating dairy cows during periods of a depressed rumen pH

¹SEM standard error of mean
^{a, b}LSmeans with different letters within SCFP treatment (No SCFP or SCFP) differ (P < 0.05)
^{x, y}LSmeans with different letters within SCFP treatment (No SCFP or SCFP) tend to differ (P < 0.10)
