Abstract |
In this study, we conducted a next generation sequencing based microbial community analysis to investigate gut
microbiota of the two commercially most available swine breeds, Yorkshire and Landrace. Bacterial 16S rRNA gene
was amplified from fecal DNA using universal primer sets designed for V4 regions. Our comparison analysis of the
gut microbiota of the two breeds suggested that their gut microbiota changed depending on the growth stages, while
the difference between the two breeds was insignificant. However, there was a limited number of genera, the
abundance of which was found to be different between the breeds. Those included the genus Xylanibacter in the
Yorkshire samples, which was previously reported as a fiber digesting bacteria, likely increasing energy harvesting
capacity of swine. In addition, others included opportunistic pathogens mostly found in the Yorkshire samples while
the Landrace samples had significantly more prevalent Clostridium_IV species that were known to play a key role in
systemic immunity of hosts. While microbial community shifts was found to be associated with growth stages, the
difference between the two breeds seemed to be insignificant. However, there were several bacterial genera showing
differential abundance, which may affect growth of hosts. |
