Post-fermentation parameters correlated with MDS and CARTs analyses for TGP and CH₄ production.

For TGP and CH4 production, (n = 3–4) species not connected by the same letters within the same column are significantly different. r = Pearson's correlation coefficients from MDS analysis; C2, acetate; C3, propionate; C4, butyrate; Iso C4, Iso-butyrate; C5, valerate; Iso C5, Iso -valerate C2∶C3, acetate/propinate ratio; OMd, organic matter degraded; DCS, decorticated cottonseed meal; SEM, standard error mean.
