ABSTRACT:
ABSTRACT: Live yeasts may favor ruminal fermentation and nutrient utilization in small ruminants. Their action is associated with the modulation of microbial activity, maintenance of anaerobic conditions, stimulation of cellulolytic and lactate-utilizing bacteria, as well as changes in volatile fatty acid production and nitrogen utilization. These mechanisms may enhance fiber degradation, minimize lactate accumulation, and contribute to the stability of the ruminal environment. The effects of supplementation may also influence feed intake, digestibility, and productive performance. In goats and sheep, positive responses in digestibility, weight gain, and feed efficiency have been reported, although results are variable. This chapter was developed based on a literature review on the use of Saccharomyces cerevisiae in goat and sheep nutrition, with searches conducted in the CAPES Journals Portal and PubMed, using Elicit as a supporting tool. Supplementation with Saccharomyces cerevisiae has the potential to improve the ruminal environment, digestibility, and performance of small ruminants. However, the variability in the reported results highlights the need for studies to establish appropriate inclusion levels under different dietary and production conditions.
