Abstract

This study investigated the effects of dietary lauric acid (LA) and monolaurin (MLA) supplementation in animal feed on rumen fermentation and methane emissions. Notably, dietary LA supplementation resulted in a more significant reduction in methane emissions compared to MLA, while the decrease in volatile fatty acid (VFA) levels was relatively smaller. These findings suggest that LA is more effective as an enteric methane mitigator and can maintain rumen fermentation without adversely affecting livestock productivity. However, the great heterogeneity observed across studies highlights the influence of varying analytical conditions and basal feed compositions. Future research should focus on exploring the synergistic potential of combining dietary LA and MLA, conducting comprehensive livestock feeding trials, and evaluating the additives’ effects on growth performance, potential side effects, and carcass quality. By addressing these aspects, the practical applications of these additives can be optimized for sustainable livestock management.
