Interpretive summary: Dietary components and changes cause shifts in the ruminal microbial ecology that can play a role in animal health and productivity, but the magnitude of these changes remains unknown. The objective of this study was to utilize pyrosequencing to analyze the diversity of ruminal bacterial populations of cattle fed citrus pulp pellets (CPP), which are fed to cattle to improve animal growth and have an impact on foodborne pathogenic bacteria in live cattle. 0, 10, or 20% of the concentrate portion of the ration was replaced with citrus pulp pellets (CPP,) and the microbial population of the rumen was found to change only slightly. Overall, there were relatively few changes in ruminal microbial populations possibly due to a lack of essential oils in the CPP which are thought to be critical in the alteration of ruminal microbial populations.
