Fig. 7From: Effects of supplemental xylanase and xylooligosaccharides on production performance and gut health variables of broiler chickensA heatmap showing an association between some cecal bacterial species and biological parameters across all treatments in broilers at d 42 post-hatch. The Spearman’s rho (ρ) correlation coefficient is denoted by the color of the heatmap, and the values are represented in the legend, where the blue color denotes negative correlation while the brown color denotes positive correlation. The yellow asterisks in the cell indicate a statistically significant correlation (*P ≤ 0.05, **P ≤ 0.01), while the dots indicate approaching significance or a trend (P < 0.1). The dendrogram is generated by the Euclidean distance method and represents the clustering of bacterial species. ADFI: average daily feed intake, ADG: average daily gain, FCR: feed conversion ratio.
