The Role of Yeast Saccharomyces cerevisiae in Supporting Gut Health in Horses: An Updated Review on Its Effects on Digestibility and Intestinal and Fecal Microbiota.

Abstract: To support the overall health of horses, it is essential to maintain an optimal gut health (GH) status, which encompasses several physiological and functional aspects, including the balance and functionality of intestinal microbial populations and, accordingly, the effective digestion and absorption of nutrients. Numerous biotic and abiotic stressors can lead to an imbalance of GH, such as the quality of forages and the composition of diet, e.g., the inclusion of high energy-dense feeds to meet the energy requirements of performance horses. To support the digestive function and the intestinal microbial populations, the diet can be supplemented with feed additives, such as probiotic yeasts, that promote the ability of cellulolytic bacteria in the hindgut to digest the available fiber fractions, finally increasing feed efficiency. Among the different yeasts available, is the most used in horses' nutrition; however, results of digestibility trials, as well as data on intestinal and fecal microbial populations, are sometimes contradictory. Therefore, the purpose of this review is to summarize the effects of on in vivo and in vitro digestibility, providing an updated overview of its effects on the intestinal and fecal microbial population.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article discusses the role of Yeast Saccharomyces cerevisiae as a dietary supplement to support gut health in horses by promoting the digestibility of nutrients and maintaining a balance of intestinal microbes.

Importance of Gut Health in Horses

  • The overall health of horses significantly relies on the health of their gut. Gut health in horses involves several physiological and functional aspects, majorly the balance of intestinal microbiota, which hugely contributes to the digestion and absorption of nutrients in their system.
  • Various biotic and abiotic stressors affect the balance of the gut health. For instance, the quality and composition of the horse’s diet greatly impacts the gut health. The inclusion of high energy-dense foods in the diet of performance horses is one of the significant factors keeping the gut health in balance.

Role of Probiotic Yeasts in Horse Diet

  • To aid the digestive function and help maintain the intestinal microbial populations, the horse’s diet can be supplemented with probiotic yeasts that are known to enhance the ability of cellulolytic bacteria to digest the available fiber fractions in the hindgut, hence increasing feed efficiency.
  • Saccharomyces cerevisiae is one such probiotic yeast commonly used in horse nutrition to support gut health.

Effects of Saccharomyces cerevisiae on Digestibility and Microbial Populations

  • However, research has provided contradictory results concerning the effects of Saccharomyces cerevisiae on the digestibility and intestinal and fecal microbial populations in horses. This discrepancy has led to inconclusive evidence regarding its effectiveness in improving gut health and nutrient assimilation in horses. Therefore, this review aims to consolidate the various effects of Saccharomyces cerevisiae documented in previous scientific studies.
  • The article aims to provide an updated summary of the effects of Saccharomyces cerevisiae on in vivo and in vitro digestibility, its impacts on intestinal and fecal microbial populations, and overall gut health in horses.
