Effects of SPC supplementation in the starter diet on the relative abundance of the top 30 bacteria at the genus level of broilers. The values in the histogram are individual sample values from maximum to minimum (n = 8), *P < 0.05. Control = control group; SPC12 = supplementation with 12% SPC to the starter diet group. A Relative abundance of caecal microflora in the top 30 at d 10; B Relative abundance of caecal microflora in the top 30 at d 42; C Relative abundance of Alistipes at d 10; D Relative abundance of Anaerotruncus at d 10; E Relative abundance of Erysipelatoclostridium at d 10; F Relative abundance of Intestinimonas at d 10; G Relative abundance of Flavonifractor at d 10; H Relative abundance of Marvinbryantia at d 10; I Relative abundance of Alistipes at d 42; J Relative abundance of Intestinimonas at d 42. K Relative abundance of Flavonifractor at d 42; L and N LEfSe analysis of caecal microflora at d 10; M and O LefSe analysis of caecal microflora at d 42
