摘要：

The objective of this study was to evaluate the effect of low dietary protein sources on the gut microbiota in finishing pigs. Thirty-six Duroc x Landrace x Large White finishing barrows were randomly allocated to four equal groups. Soybean meal (SBM) as a protein source is a control group and had a general protein level of 15% (SBM15). The pigs fed soybean meal (SBM11), soybean-cottonseed corn germ meal (SCCM11), and cottonseed-corn germ meal (CCM11) were offered low protein (11%) diets. The results showed that the ileum and feces microbiota of the SCCM11 group were significantly increased compared to the SBM15 group (P<0.05). At the phylum level, the relative abundance of Proteobacteria phyla was significantly increased in the ileum microbiota of the SCCM11 group compared to the SBM15 group (P<0.05). At the genus level, the abundance of Lactobacillus and Bifidobacterium showed a significant increase in the ileum microbiota of the SCCM11 group (P<0.05). The abundance of Ruminococcaceae, Phascolarctobacterium was significantly increased in the feces microbiota of the SCCM11 group than the other three groups (P<0.05). These results indicated that the SCCM11 group with added crystalline amino acid may modulate intestinal microbiota.
