“…The potential mechanisms have been demonstrated for health benefits of yeasts as efficient probiotics in the animal production can be identified and are attributed to the ability to be involved in highlighting these criteria (Fig. ): (i) adhesion capacity to intestinal cells (ii) improvement in feed digestibility and enhancement of beneficial micro‐organisms in the gut, (iii) promotion of digestive enzyme activity, (iv) immunostimulant effect, (v) tolerance to high acidity (vi) resistance to bile salts (vii) improving gut morphological structure (Pourabedin et al ) and (viii) direct antagonistic effect on enterobacteria and other yeasts and inhibition of the formation of destructive bacteria (Ogbuewu et al ) (Fig. ).…”

“…Therefore probiotics such as yeast S. cerevisiae have been evaluated among others as potential feed supplements to improve feed utilization, enhance feed digestibility, reduce the number of pathogens (Haldar et al ), improve animal performance and health (Cheng et al ). Yeast is known to induce positive effects in both ruminants and nonruminants; yeast supplementation also reduces the negative environmental impacts of livestock production (Ogbuewu et al ). In available scientific literature, supplementation of monogastric feed with live yeast cells did not show uniform results.…”

The production of livestock and poultry faces major challenges to meet the global demand for meat and dairy products and eggs due to a steady increase in the world’s population and the ban of antibiotics in animal production. This ban has forced animal nutritionists to seek for natural alternatives to antibiotics. In this context, the yeast Saccharomyces cerevisiae has received considerable attention in the last decade. It has been reported that feed supplementation with live yeast cells improve feed efficiency, enhance feed digestibility, increase animal performance, reduce the number of pathogenic bacteria, improve animal health and reduce the negative environmental impacts of livestock production. The current review sheds light on the effects of the use of live S. cerevisiae cells in the diets of nonruminant and pseudo‐ruminant’s animals and the mechanisms by which they exert its effects. This review work revealed that the addition of S. cerevisiae in poultry feed causes a phenomenon called competitive exclusion of pathogenic bacteria capable of causing disease adhere to the yeast surface, and so removing a large amount of harmful micro‐organisms and allowing the Animal defend more effectively, the production of antimicrobial agents, the balancing the gut microbiota and stimulation of host adaptive immune system and improving gut morphological structure, thus these benefits are reflected on the overall poultry health. In addition, in the presence of live S. cerevisiae cells, the immunity of rabbits was improved due to the high number of white blood cell. In addition, apparent digestibility of acid and neutral detergent fibre was improved in horses and rabbits. Saccharomyces cerevisiae in pig diets augment mucosal immunity by increasing IgM and IgA activity against pathogens, enhance intestinal development and function, adsorb mycotoxins, modulate gut microbiota and reduce postweaning diarrhoea.

“…The aim of these alternatives is to enhance performance while protecting environment and animal health (Mehdi et al, 2018). Thus, probiotics like yeast S. cerevisiae have been investigated as a feed additive for improve animal performance and health (Ogbuewu et al, 2018). Probiotics are live microorganisms that improve animals' health by competing with undesirable microorganisms, improve intestinal microbial balance and absorption of nutrients (Al-Khalaifah, 2018).…”

The objectives of the current study were to investigate the impact of dietary yeast (Saccharomyces cerevisiae) supplementation on growth performance, some serum parameters, intestinal morphology and pathogens reduction in Japanese quails. In total, 300 d-old Japanese quails were randomly allocated to 5 dietary groups (6 replicates of 10 Japanese quails per pen). At beginning of the experiment (d 14), Japanese quails fed a basal diet without contain any yeast while, the other treatments provided basal diet plus 0.5, 1.5, 2.5 and 3.5% yeast on feed basis. The results showed that dietary supplementation of yeast, particularly at a level of inclusion of 3.5% on feed basis, resulted in highest BW for Japanese quails (P<0.05). Japanese quails fed diets supplemented with yeast reduced (P<0.05) cholesterol and triglycerides concentrations in serum compared to control. Dietary yeast supplementation at 3.5% reduced (P<0.05) interleukin 1 β (IL-1 β), IL-6 and TNF-α levels in serum compared to those fed dietary yeast at level of 0.5% or fed non supplemented diets. Feeding yeast at level of 3.5% led to increase in duodenal villus height significantly compared to other treatments. Japanese quails fed yeast supplemented diets at 2.5 or 3.5% reduced E. coli (P<0.05) and C. perfringens CFU counts in excreta than those fed non supplemented diet. It is concluded that dietary yeast supplementation of Japanese quails improved growth rate as a result of an increase in villus height and a reduce in the counts of E. coli and C. perfringens.

“…Manipulating the rumen microbiome to enhance productivity and health of ruminants could be limited by the resilience of the microbial community in the rumen of mature animals (Yáñez‐Ruiz et al ) . Although the effect of manipulating the rumen microbiome may not be permanent in the long term, it might have a positive effect on fattening/milk yield (Ogbuewu et al ). Yeasts have given better results in ruminants (Seo et al ).…”

Summary In ruminants, high fermentation capacity is necessary to develop more efficient ruminant production systems. Greater level of production depends on the ability of the microbial ecosystem to convert organic matter into precursors of milk and meat. This has led to increased interest by animal nutritionists, biochemists and microbiologists in evaluating different strategies to manipulate the rumen biota to improve animal performance, production efficiency and animal health. One of such strategies is the use of natural feed additives such as single‐celled fungi yeast. The main objectives of using yeasts as natural additives in ruminant diets include; (i) to prevent rumen microflora disorders, (ii) to improve and sustain higher production of milk and meat, (iii) to reduce rumen acidosis and bloat which adversely affect animal health and performance, (iv) to decrease the risk of ruminant‐associated human pathogens and (v) to reduce the excretion of nitrogenous‐based compounds, carbon dioxide and methane. Yeast, a natural feed additive, has the potential to enhance feed degradation by increasing the concentration of volatile fatty acids during fermentation processes. In addition, microbial growth in the rumen is enhanced in the presence of yeast leading to the delivery of a greater amount of microbial protein to the duodenum and high nitrogen retention. Single‐celled fungi yeast has demonstrated its ability to increase fibre digestibility and lower faecal output of organic matter due to improved digestion of organic matter, which subsequently improves animal productivity. Yeast also has the ability to alter the fermentation process in the rumen in a way that reduces methane formation. Furthermore, yeast inclusion in ruminant diets has been reported to decrease toxins absorption such as mycotoxins and promote epithelial cell integrity. This review article provides information on the impact of single‐celled fungi yeast as a feed supplement on ruminal microbiota and its function to improve the health and productive longevity of ruminants.
