Effects of Saccharomyces cerevisiae fermentation-derived postbiotic on methane production and plasma metabolome of fattening Holstein steers fed a high grain diet.

This study assessed the effects of feeding Saccharomyces cerevisiae fermentation-derived postbiotic (SCFP) on methane production and plasma metabolome of Holstein steers on a finishing diet. Twelve Holstein steers (n = 6 per treatment) were enrolled in a randomized complete block design and blocked into 3 groups based on their initial body weight (BW: 294 ± 12.7 kg).

Effects of fermentation product on ruminal fermentation, total tract digestibility, blood proinflammatory cytokines, and plasma metabolome of Holstein steers fed a high-grain diet.

This study aimed to assess the impact of fermentation product (SCFP) on digestibility, ruminal fermentation, and plasma metabolome of Holstein steers fed a high-grain diet. Steers were fed diet with 80% concentrate and 20% corn silage once daily ad libitum. Steers were stratified based on initial body weight (BW) and randomly assigned to two treatments: 1) control (CON), a basal diet without SCFP; 2) basal diet + 12 g/head/day SCFP, top-dressed.
