A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

The Oxidation Mechanisms of Saturated Fatty Acids: Formation of Hydroperoxide Isomers and Production of 2‐Alkanones and Lactones

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saturated fatty acids (SFAs) are generally regarded simply as being resistant to oxidation compared with unsaturated fatty acids. However, it has long been reported that SFAs can undergo oxidation when heated at high temperatures, leading to the formation of unique degradation products such as 2‐alkanones and lactones.

MICROBIAL PROTEIN PRODUCTION IN THE RUMEN OF STEERS FED LOW QUALITY FORAGE SUPPLEMENTED WITH VARIOUS LEVELS OF BARLEY GRAIN OR BARLEY GRAIN PLUS PROTEIN [PDF]

, 2006
An experiment was conducted to examine the effects of increasing intake of barley grain or barley grain plus protein as supplement on microbial crude protein (MCP) production, efficiency of microbial crude protein production (eMCP) in the rumen of ...

Accumulation of trans C18:1 fatty acids in the rumen after dietary algal supplementation is associated with canges in the Butyrivibrio communitytrans

, 2008
Optimization of the fatty acid composition of ruminant milk and meat is desirable. Dietary supplementation of algae was previously shown to inhibit rumen biohydrogenation, resulting in an altered milk fatty acid profile.

In vitro study of dietary factors affecting the biohydrogenation shift from trans-11 to trans-10 fatty acids in the rumen of dairy cows [PDF]

, 2012
On the basis of the isomer-specific effects of trans fatty acids (FA) on human health, and the detrimental effect of t10,c12-conjugated linoleic acid (CLA) on cows’ milk fat production, there is a need to identify factors that affect the shift from trans-

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Can a fermentation gas mainly produced by rumen Isotrichidae ciliates be a potential source of biohydrogen and a fuel for a chemical fuel cell? [PDF]

, 2010
Bacteria, fungi and protozoa inhabiting the rumen – the largest chamber of the ruminants’ stomach, release large quantities of hydrogen during the fermentation of carbohydrates.

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

Animal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]

, 2004
The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

Early life treatment with Lacticaseibacillus rhamnosus strains drives reduced enteric methane emissions in dairy heifers

Journal of Animal Science and Biotechnology
Background Methane emissions from enteric fermentation in ruminant livestock make up 27% of anthropogenic methane emissions. Results Screening > 1,700 lactic acid bacteria identified Lacticaseibacillus rhamnosus FNZ118 (Kowbucha™ FNZ118) and L. rhamnosus
