Diversity measures (beta-diversity) for the cecal bacterial communities in the second trial. Diversity measures (beta-diversity) for the cecal bacterial communities of chickens in the control group, and the groups receiving wax and fat-protected butyrate. Cecal content was collected from the 21-day-old chickens in the first trial, 4 days after Salmonella infection, while receiving a standard diet supplemented with wax (blue) or fat-protected butyrate (green) or non-supplemented (pink) for 21 consecutive days. The PCoA plot of the abundance based on Bray–Curtis dissimilarity matrix showed diet-related clustering indicated with ellipses with p-value < 0.001, and was created with the web-based tool MicrobiomeAnalyst [47].
