Theoretical Methane Emission Estimation from Volatile Fatty Acids in Bovine Rumen Fluid

Methane production from livestock farming is recognized as an important contributor to global GHGs. Volatile fatty acids (VFAs) found in bovine rumen may be utilized a substrate for methanogens form CH4, and thus improvement of quantitative VFA measurements can help facilitate greater understanding mitigation CH4 production. This study aims contribute the development more accurate methods quantification specification VFAs rumen. The were analyzed using conventional method alternative catalytic esterification reaction (CER) method. Substantial differences detected concentrations C3+ (chain length ≥ 3) observed between both methods, especially butyric acid. Evaluation sensitivity detecting standard solutions confirmed that values resulting CER closer known solution than those results this provide first proof show improved accuracy when compared with Therefore, recommended analyze rumen, acid other VFAs.
