    Abstract:
    Swine have a complex microbial community within their gastrointestinal tract that plays a critical role in both health and disease. High-throughput 16S rRNA gene-based pyrosequencing was used to identify the possible core microorganisms in the gut of swine groups that differ in meat quality and weight grades (level 1 as higher meat quality and level 2 as lower meat quality). Samples were taken from the rectum and/or stool from ten animals, DNA was extracted, and the V1-V3 regions of the 16S rRNA gene were amplified. Two bacterial populations (Bacteroidetes and Firmicutes) dominated and were shared between the two groups. Significant differences between the groups were found at the genus level. The genera Lactobacillus and Oscillibacter were found in slightly higher proportions in the level 2 group (12.6 and 12.4% of the classified reads, respectively) than those of level 1 (9.6 and 7.7%, respectively). By contrast, the proportion of reads assigned to the genus Roseburia in the level 1 group (13.0%) was higher than that of level 2 (4.8%). The largest differences were related to the genera Clostridium, Oscillibacter, and Roseburia as core microorganisms. Moreover, two genera, Roseburia and Clostridium, related to level 1 produced linoleic acid or short chain fatty acids that might contribute to swine health and development. In conclusion, the presence of core bacteria in the swine gut is associated with meat quality with reduced body fat in swine.
