20.500.12556/RUL-163130 Rumen gas kinetics a comparative analysis of two in vitro assessment methods for forage evaluation Kinetika plinov v vampu Gas production from thirty samples of feedstuffs (10 samples of corn silage, grass silage, and grass hay, respectively) was assessed in vitro using two methods: the Hohenheim gas test (HGT) and the ANKOM RF Gas Production System (ANKOM). Samples were incubated in buffered rumen fluid. Gas kinetic parameters were calculated using the Gompertz model. Results revealed significantly lower gas production with the ANKOM compared to the HGT. Significant differences were observed between the HGT and ANKOM in the specific gas production rate (parameter C), maximum fermentation rate (MFR) and gas produced after 24 h of incubation (Gas24) for each feed group. High coefficients of determination (R2) were calculated between the methods for the gas kinetic parameters MFR, Gas24, total potential gas production (parameter B), decrease in the specific gas production rate (parameter A), moderate R2 for C, and low R2 for time of maximum fermentation rate (TMFR). Despite the lower quantities of gas generated with the ANKOM, there are strong correlations in the parameters of gas kinetics that promise the possibility of developing correction models. Future development of such models could position the ANKOM as a viable alternative to HGT, particularly for calculating metabolizable energy and net energy for lactation in feedstuffs. animal nutrition rumen gas production gas kinetic parameters Ankom RF Gas Production System Hohenheim Gas Test prehrana živali vamp produkcija plinov kinetika produkcije plinov parametri metoda ANKOM Hohenheimski plinski test true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-02 11:25:18 2024-10-02 11:25:19 2026-07-29 12:18:33 0000-00-00 00:00:00 2024 0 0 7 str. no. 1 Vol. 120 2024 0000-00-00 Zaloznikova NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 636.084/.087 1854-1941 10.14720/aas.2024.120.1.16702 206986755 16702_54967_Valcl_120-1.pdf 16702_54967_Valcl_120-1.pdf 1 6DF3064B670E14783055306DD1A8A323 f03519d49447535577eac86abe2ee5411e280264dc7531e8a3a4eb4d06748918 ae65549d-80a0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=192629 https://journals.uni-lj.si/aas/article/view/16702 1 163dfd72-80a0-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=192628 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
