Abstract

It can be concluded that S. cerevisiae had significantly increased microbial protein and NH<sub>3</sub>-N concentrations after fermentation without altering pH. Additionally, the addition of S. cerevisiae enhanced TGP and reduced methane emissions. It is worth noting that TGP increased because B. subtilis was added at a concentration of 20 × 10<sup>6</sup> CFU g<sup>-1</sup>, with no significant differences between concentrations. Therefore, we recommend adding S. cerevisiae and B. subtilis to the diet at doses of 8 and 20 × 10<sup>6</sup> CFU g<sup>-1</sup>, as it resulted in higher TGP and reduced methane emissions. © 2024 Society of Chemical Industry.
