^aAverage abundances of important OTUs in ileal microbial communities of birds fed either a barley (B) diet or barley-plus-enzyme (BE) diet are shown. OTUs are listed in order of their contribution (_i) to the average dissimilarity δ (= 72.86%) between diets. The percent contribution of individual OTUs and the cumulative percent contribution to the top 50% of average dissimilarities are shown. OTUs identified as being good discriminators between diets are marked with an asterisk in column 1.
