FIG 4.
Correlations between OTU at 29 dph and feed efficiency, performance traits, and excreta characteristics. Correlations were significant (P ≤ 0.05) if correlation coefficients were ≤−0.33 or ≥0.33. The OTU were included in the matrix if they occurred in at least half of the chickens and if they were significant for at least one of the parameters. Low-RFI FMT females, n = 8; low-RFI FMT males, n = 7; high-RFI FMT females, n = 7; high-RFI FMT males, n = 6; low-RFI CT females, n = 7; low-RFI CT males, n = 7; high-RFI CT females, n = 7; high-RFI CT males, n = 7. RFI, residual feed intake; TFI, total feed intake; TBWG, total body weight gain; DM, dry matter; NH3, ammonia; FM, fresh matter.
