Gut microbiota compositions for two lines (HW and LW) of chickens with different quantitative genotypes.

(a) Distribution of gut microbiomes composite for HW females, HW males, LW females and LW males at the genera level. (b) The principal components analysis (PCA) plot of 56 samples from HW and LW lines using 29 gut microbiome species which were affected by quantitative genetics background. (c) PCA plot of 56 samples from HW and LW lines using 11 gut microbiome species belong to Lactobacillus which were affected by gender. (d) PCA plot of 29 samples from HW and LW males using 8 gut microbiome species which were affected by quantitative genetic background. (e) PCA plot of 27 samples from HW and LW females using 20 gut microbiome species which were affected by quantitative genetic background.
