Muscle FA and mucosal microbiota that were differentially expressed between obese Ningxiang pigs (NX) and lean DLY pigs

The longissimus muscle and ileal mucosa samples from 43 obese Ningxiang pigs and 50 commercial lean DLY pigs were collected for FA and gut microbiota analyses.

(A) Marbling score.

(B) pH value of muscle.

(C) Muscle FA concentrations.

(D) Differential FAs between Ningxiang pigs and DLY pigs.

(E) Pearson correlation analysis between FAs and meat quality.

(F) Bacterial α-diversity (ACE, Chao1, and Simpson indices).

(G) Bacterial β-diversity (PCoA plot).

(H) Marked associations between the top 100 genera and muscle FAs.
