Unlocking Insights into Saccharomyces cerevisiae and Milk Yields: A Meta-Analysis

Dairy farming’s sustainability thrives on profitable milk production, which demands an in-depth knowledge of influencing aspects. One of the dietary aspect involves Saccharomyces cerevisiae, a yeast that improves nutrient digestibility and milk yield. This meta-analysis, encompassing 44 research studies and 59 comparisons, investigates the link between Saccharomyces cerevisiae supplementation and milk yield in Holstein, Holstein-Friesian, and Holstein-Friesian x Thai Native cattle. Key factors such as milk yield, breed, and Saccharomyces cerevisiae dosage were retrieved and evaluated using OPENME and Minitab, with RSM and meta-analysis approaches. The results show that Saccharomyces cerevisiae has a statistically substantial and moderate effect on milk yield (Hedges’ d = 0.240). Sub-group analyses suggest breed-specific effects, and recommend optimal dosage of 173.1 g for increased milk output in dairy calves. The findings are useful for future research studies Dairy farming’s sustainability thrives on profitable milk production, which demands an in-depth knowledge of influencing aspects.
