Sammanfattning
This study aimed to examine the effects of rumen-protected choline and methionine (RPC and RPM, respectively), with respect to their chemical composition, on in vitro accumulated biogas (BG), kinetics, and in vitro rumen fermentation profile. This study was carried out at different incubation time intervals utilizing an in vitro gas production approach. The experimental design was a 2x2 factorial arrangement in a completely randomized design (CRD) with six replicates per treatment. Total gas production volume and fermentation parameters were measured at 2, 4, 6, 8, 12, 24, 36, 48, 72, and 96 hours of incubation. The addition of experimental RPC, RPM, or their mixture did not affect cumulative gas production and gas production kinetics during the various incubation times compared to the control group in terms of b (mL/g DM; P = 0.15), c (fraction per h; P = 0.14), L (fraction per h; P = 0.21), or both (P > 0.05). For all evaluated parameters of the in vitro rumen fermentation profile, including pH, DMD, OMD, and SCFA, no interactions were observed compared to the control (P > 0.05). Overall, the findings showed that the values of the experimental groups for rumen fermentation, gas production kinetics, and in vitro accumulative gas production were identical. Additional studies are required to test the correctness and precision of the current data offered in the paper through using up to update technology.
