The purpose of the study was to evaluate the effects on fermentation parameters of replacing alfalfa hay in ruminant diets with amarant (Amaranthus caudatus) hay. Diets containing amaranth hay at 0%, 10%, 20%, and 30% were created using in vitro gas generation, preserving isocaloric and nitrogenic levels. There were significant changes in true digestible dry matter (TDDM), true digestibility (TD), gas and methane output per digested dry matter (DM), and microbial protein, but not in methane (CH4) production. Substituting alfalfa with amaranth hay resulted in relatively higher microbial protein synthesis compared to gas and methane production, supporting the potential for up to 30% replacement. This change improved microbial protein and decreased methane output. To assess its effect on feed intake and overall animal production, more in vivo studies are required.
