This study aimed to investigate the effects of dietary supplementation of different dosages of active dried yeast (ADY) on the fecal methanogenic archaea community of dairy cattle. Twelve multiparous, healthy, mid-lactating Holstein dairy cows (body weight: 584 ± 23.2 kg, milk produced: 26.3 ± 1.22 kg/d) were randomly assigned to one of three treatments (control, ADY2, and ADY4) according to body weight with four replicates per treatment. Cows in the control group were fed conventional rations… 
Effect of Limit-Fed Diets With Different Forage to Concentrate Ratios on Fecal Bacterial and Archaeal Community Composition in Holstein Heifers
TLDR
The findings support the potential for microbial manipulation by diet, which could enhance feed digestibility and relieve environmental problems associated with heifer rearing, and provide a better understanding of fecal fermentation parameters and microbiota under a wide range of dietary F:C.
Effect of Dietary Supplementation of Moringa Oleifera on the Production Performance and Fecal Methanogenic Community of Lactating Dairy Cows
TLDR
The study’s main results suggest that inclusion of Moringa oleifera improved milk fat content and changed the composition and diversity of methanogenic community in lactating cows, and indicates that secondary metabolites from Moreda olifera may regulate fermentation conditions and associations between some methanogens and other microbes.
Potential impacts of dietary Lemna gibba supplements in a simulated ruminal fermentation system and environmental biogas production
Abstract Enteric methane production from ruminants contributes to current global warming challenges faced by mankind. Supplements that improve nutritive value of diets are potential mitigating
Camelina sativa L. Oil Mitigates Enteric in vitro Methane Production, Modulates Ruminal Fermentation, and Ruminal Bacterial Diversity in Buffaloes
TLDR
It is concluded that CO enhanced fermentation kinetics while decreasing enteric in vitro CH4 production from fibrous diets and may be considered as a potentially effective and environmentally friendly way of mitigating CH4 emission from livestock.
Dynamic role of single‐celled fungi in ruminal microbial ecology and activities
TLDR
Yeast inclusion in ruminant diets has been reported to decrease toxins absorption such as mycotoxins and promote epithelial cell integrity and its function to improve the health and productive longevity of ruminants is provided.
Effects of particle size of ground alfalfa hay on caecal bacteria and archaea populations of rabbits
TLDR
Both the bacterial and archaeal population in the caecum of rabbit experienced alterations, however archaea response earlier than bacteria to the decrease of alfalfa meal particle size was found.
The structure of microbial populations in Nelore GIT reveals inter-dependency of methanogens in feces and rumen
TLDR
Co-occurrence among ruminal and fecal ASVs reinforces the relationship of microorganisms within a biological niche and indicates a dependency of the predominant fecal methanogen population on the rumen population.
Bacterial Community Diversity Associated With Different Utilization Efficiencies of Nitrogen in the Gastrointestinal Tract of Goats
TLDR
An association of GIT microbial communities as a factor that influences UEN in goats is suggested, as a significant correlation was observed between the UEN and the genera Succiniclasticum, Bacteroides, Ruminobacter, Methanimicrococcus, Mogibacterium, Eubacterium_hallii_group and Ruminococcus_1.
Peer Review #1 of "Effects of particle size of ground alfalfa hay on caecal bacteria and archaea populations of rabbits (v0.2)"
This work was aimed to investigate the effects of the different particle size of ground alfalfa hay on caecal microbial and archeal communities of rabbits. One hundred-twenty New Zealand rabbits
Potential use of chromium to combat thermal stress in animals: A review.
TLDR
Chromium (Cr) is believed to increase insulin action in insulin-sensitive tissues (i.e., adipose and muscles), resulting in increased farm animal productivity through the improvement of feed intake, growth rate, carcass quality, reproductive parameters and immune functions.

Effect of supplementation of allicin on methanogenesis and ruminal microbial flora in Dorper crossbred ewes
TLDR
Supplementation of AL at 2.0 g/head·day effectively enhanced OM, N, NDF, and ADF digestibility and reduced daily methane emissions in ewes, probably by decreasing the population of ruminal protozoans and methanogens.
Rumen bacterial, archaeal, and fungal diversity of dairy cows in response to ingestion of lauric or myristic acid.
TLDR
Results indicate that LA, either through antiprotozoal or direct antimicrobial effects, altered bacterial and archaeal populations in the rumen of dairy cows, but effects on fungal populations were not clear.
Effect of camelina oil or live yeasts (Saccharomyces cerevisiae) on ruminal methane production, rumen fermentation, and milk fatty acid composition in lactating cows fed grass silage diets.
TLDR
Results indicated that live yeasts A and B had no influence on animal performance, ruminal gas production, rumen fermentation, or nutrient utilization in cows fed grass silage-based diets.
The effects of active dried and killed dried yeast on subacute ruminal acidosis, ruminal fermentation, and nutrient digestibility in beef heifers.
TLDR
The study demonstrates the positive effects of yeast, irrespective of its viability, in reducing the severity of SARA, and further studies are required to evaluate the importance of yeast viability for other dietary conditions, particularly when the risk of acidosis is high.
Effect of dietary supplementation with live-cell yeast at two dosages on lactation performance, ruminal fermentation, and total-tract nutrient digestibility in dairy cows.
TLDR
The addition of 4 g/cow per day of LCY to HS diets tended to increase milk fat content and increased total-tract fiber digestibility in dairy cows and the effect of dietary supplementation with live-cell yeast at 2 dosages in high-starch diets was determined.

Effects of active dry yeasts on the rumen microbial ecosystem : Past, present and future
TLDR
The objectives of this paper are to review the most important findings on effects of ADYs in the rumen, to describe identified modes of action, and to provide thoughts for further strain selection and applications in ruminant nutrition.
The Effect of Dietary Replacement of Ordinary Rice with Red Yeast Rice on Nutrient Utilization, Enteric Methane Emission and Rumen Archaeal Diversity in Goats
TLDR
Red yeast rice is a potential feed ingredient for mitigation of enteric methane emissions of goats, however, caution should be taken when it is used because it may inhibit the digestibility of some nutrients.

TLDR
The data indicate that the methanogenic ecology at the species, strain, and/or genotype level in the rumen may play important roles in contributing to the difference in methane gas production between cattle with different feed efficiencies.
