Fig. 2From: Astragalus affects fecal microbial composition of young hens as determined by 16S rRNA sequencingRarefaction curve sequences showing the complexities of the microbial communities in the fecal samples of 27 young hens. Samples A1–A13 were collected from hens fed conventional feed supplemented with a crude Astragalus (0.5%) additive, while samples B1–B14 were collected from hens fed conventional feedBack to article page
