dc.description.abstractForages and concentrates have consistently distinct patterns of fermentation in the rumen, with forages producing more methane (CH?) per unit of digested organic matter (OM) and higher acetate to propionate ratio than concentrates. A mechanism based on the Monod function of microbial growth has been proposed to explain the distinct fermentation pattern of forages and concentrates, where greater dilution rates and lower pH associated with concentrate feeding increase dihydrogen (H?) concentration through increasing methanogens growth rate and decreasing methanogens theoretically maximal growth rate, respectively. Increased H? concentration would in turn inhibit H? production, decreasing methanogenesis, inhibit H?-producing pathways such as acetate production via pyruvate oxidative decarboxylation, and stimulate H?-incorporating pathways such as propionate production.
