“…Some experiments have illustrated the fact that Eh is an indicator of bacterial activity. Studies conducted in calves from birth to weaning byRey, Enjalbert, and Monteils (2012) andJulien et al (2015) have shown that the Eh in the rumen takes positive values in the first day of life then declines over few days to reach highly negative values, characteristic of a strong reducing environment. The values range from +224 mV at birth to −141 mV at weaning for Rey et al(2012) and from +253 mV to −159 mV for Julien et al (2015).…”

SummaryThe ruminal ecosystem is a fermentative milieu which is interesting to discuss in terms of its redox status as a reflection of an intense bacterial activity. The objective of this systematic literature review is to quantitatively analyze data collected on redox potential (Eh) in the rumen and to explore relationship between ruminal Eh, nature of the diet fed to ruminants, and ruminal fermentation parameters. Data obtained from 15 studies comprising 24 different diets was used in the analysis. Studies included in the data file were selected based on the criteria of: (i) the nature of the reference electrode was specified, (ii) the ruminal Eh was recorded simultaneously to pH, (iii) animal body weight (BW) and dry matter intake (DMI) were reported and (iv) the composition of the diet was precisely described.

“…Muhammed and He () reported that the addition of S. cerevisiae improved rumen environment across treatments with greater total VFA, propionic and butyric acids. Live yeast used as a dietary feed additive permits a better utilization of diet in dairy cows (Julien et al ) and moreover, increased ruminal total VFA. Saccharomyces cerevisiae fermentation product supplementation manipulated rumen microbial population and resulted in improved energy supply (enhanced VFA production) and improved protein nutrition (higher microbial protein synthesis and more efficient conversion of dietary N to milk N) of lactating cows fed diets containing low‐quality forages (Zhu 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.

“…In addition, Salvati et al [4] have demonstrated under heat stress conditions the beneficial effects of supplementation with live yeast in terms of more effectively controlling an animal's homeothermy and hence maintenance of milk production. This improvement in the performance of animals receiving live yeast is explained mainly by the animal's ability to use feed more effectively: Julien et al [9] have observed an increase of between 0.8 and 3.7 points in the digestibility of total organic matter in lactating dairy cows receiving probiotic yeast supplementation. Regarding fibre degradation, Marden et al [7] have reported that probiotic yeast supplementation in dairy cows with digestive disorders such as subclinical ruminal acidosis significantly increased total fibre digestibility from 29.6% to 41.6%.…”

Probiotic yeasts are used widely today in the diets of dairy cows with a high production potential. Various studies have researched the effects of live yeasts, in particular Saccharomyces cerevisiae, on digestion, metabolism and performance in dairy cows. The present study aims at evaluating the beneficial effects of using probiotic yeast in dairy cattle farms as a means of improving the breeding performance of milking cows. A group of 14 dairy cattle farms, with at least 40 dairy cows, was selected for the study, all of them using artificial insemination (AI) and that had not used probiotics in the two milking years preceding the study. On these farms, the lactating cows received probiotic yeast supplementation (5 g/cow/day, Actisaf ® , Saccharomyces cerevisiae Sc47-CNCM I-4407, 1.10 10 CFU/g, Phileo Lesaffre Animal Care,
