Effects of Enteromorpha prolifera polysaccharides on cecal microbiota in yellow-feathered broilers under heat stress. A Alpha diversity of cecal microbiota, B Detection of intergroup distance of cecal microbiota composition based on distance matrix analysis, C Principal component analysis (PCA) of cecal microbiota composition between groups, D Correlation analysis of cecal microbial proportions at the genus level with growth performance and jejunal barrier function among three groups, red represents a positive correlation, while blue represents a negative correlation. TN Thermal neutral zone, HS Heat stress, HSE Heat stress group supplemented 0.1% Enteromorpha prolifera polysaccharides. ^*P < 0.05 and ^**P < 0.01 indicate a significant correlation
