Abstract Background A need for research searching for alternative rumen enhancers warrants immediate attention. The in vitro fermentation experiment was conducted using factorial arrangement of two factors of roughage to concentrate and seven level of red amaranth leaf powder percentage of total substrate in a Completely randomized design (CRD). Two factors, namely Factor A was two ratio of roughage (R) to concentrate (C) at 60:40 and 40:60 and Factor B was level of red amaranth (Amaranthus cruentus, L) leaf powder (RALP) supplementation at 0, 2, 4, 6, 8, 10, and 12% of total dietary substrate. Results Red amaranth leaf powder (RALP) contained phytonutrients both condensed tannins and saponins in addition with high macro minerals (Ca, K, and Mg). This experiment revealed innovations of the RALP supplementation by enhancing rumen propionate (C3) production, reducing acetate (C2) to (C3) ratio, reducing protozoal population and mitigating methane (CH4) production. Furthermore, rumen dry matter degradation percentages were remarkably enhanced (P < 0.001) by increasing RALP supplementation. Conclusion Plants rich in phytonutrients and minerals such as red amaranth leaf powder (RALP) have a vital and promising role in modulating rumen fermentation, mitigating methane production, as well as increasing substrate degradability.
