Scrophularia striata Extract Supports Rumen Fermentation and Improves Microbial Diversity in vitro Compared to Monensin

This study was designed to evaluate effects of SE on SCFA production, methane production as well as the diversity and abundance of the rumen microbiome compared to monensin in a semi continuous in vitro system. We hypothesized that feeding of SE, similar to monensin, could alter the rumen microbiome leading to beneficial modifications to rumen fermentation including increased propionate production and an inhibition of ruminal methane production.
