AB - Five corn (Zea mays) and four sorghum (Sorghum bicolor
L. Moench) silages were used to investigate the relationship between chemical
composition, In Vitro Dry Matter Digestibility (IVDMD), In Vitro Neutral
Detergent Fiber Digestibility (IVNDF) and in vitro Gas Production (GP)
measured after 1, 2, 3, 4, 5, 6, 9, 12, 24, 48 and 72 h of incubation. Then,
the capability to predict IVDMD and IVNDFD based on chemical composition and
GP data was examined. Silage contents of NDF, ADF and lignin were negatively
correlated (p<0.05) with IVDMD. A negative relationship (p<0.05) between
CP and asymptotic GP was also observed. The NDF, ADF and lignin contents of
silages were positively correlated (p<0.0001) with time to reach half-maximal
GP, however, the relationship of half-maximal GP with Non-Fibrous Carbohydrate
(NFC) was negative (p<0.0001). After the 1st h of incubation, GP was negatively
related with lignin content and positively correlated with NFC (p<0.001 and
p<0.05, respectively). After h 9 of incubation, the correlations between
NDF and ADF with GP were highest (p<0.01) until 48 h of incubation and decreased
at 72 h (p<0.05). Chemical composition combined with GP data adequately predicted
IVDMD.
