Chord diagram depicting Pearson’s correlation coefficients (r) for statistically significant relationships among the nutritional variables (p < 0.05).
Coloration and width of the ribbons indicate the direction and magnitude of the correlation, with darker blue for stronger positive (r > 0.4) and darker red for stronger negative (r < −0.3).

Dry Matter (DM), Organic Matter (OM), carbon on a wet basis (Cwb), carbon on a dry basis (Cdb), organic carbon (CO), moisture (M), Crude Protein (CP), Neutral Detergent Fiber (NDF, Acid Detergent Fiber (ADF), Nitrogen (N), Phosphorus (P), Magnesium (Mg), Potassium (K), Calcium (Ca), Sodium (Na), Zinc (Zn), Manganese (Mn), Copper (Cu) and Iron (Fe).
Table 2.
Cumulative in vitro gas production per incubated dry matter, degraded organic matter, and dry matter degradation of Piptocoma discolor. MSE = mean square of the error, CGP: production of accumulated gas, IDM: incubated dry matter; DMD: dry matter degradation, DOM: degraded organic matter.

Parameters of the Gompertz model for gas production obtained in the incubation of Piptocoma discolor forage in two contrasting landscapes (hill and alluvial plain) of the Colombian Amazon piedmont. MSE = Mean square error; a = Maximum gas production (ml); b = difference between initial gas and final gas at time x; c = Specific gas accumulation rate; TTP = Time to tipping point (h); GTP = Gas to tipping point (ml); MGPR = Maximum gas production rate (ml/h); HPI = Turning Point Time; GPI = Tipping point in gas production; TMPG = Maximum Gas Production Rate.
