Cobalt and Vitamin B12 in Dairy Cattle Nutrition: Requirements, Functions, and Interactions

Animals
Minerals are essential for ruminant health, productivity, and metabolic function, with trace minerals playing critical roles at narrow dietary margins. Cobalt (Co) is essential as it supports ruminal microbial synthesis of vitamin B12 (cobalamin), which ...

Unraveling the interaction between the phageome and bacteriome in the rumen and its role in influencing metabolome dynamics in dairy cows at different lactation stages

Microbiome
Background Although the roles of rumen microbiome in milk yield and milk protein synthesis have been widely recognized, knowledge on how ruminal microbiome dynamic changes affect these two traits during the whole lactation is lacking.

Predicting feed efficiency of Angus steers using the gastrointestinal microbiome

Animal
Microbial composition of the gastrointestinal tracts is an important factor affecting the variation in feed efficiency in ruminants. Several studies have investigated the composition of the ruminal and fecal microbiotas, as well as their impacts on feed ...

A Chiral-LC-MS Method for the Simultaneous Quantification of Short-Chain Fatty Acids and D/L-Lactate in the Ruminal Fluid of Dairy Cows

Molecules
Short-chain fatty acids (SCFA) and lactate in ruminal fluid are products resulting from the microbial fermentation of substrates and can be used to reflect the composition and activity of the ruminal microbiome.

Effects of two types of Coccomyxa sp. KJ on in vitro ruminal fermentation, methane production, and the rumen microbiota.

PLoS ONE
Coccomyxa sp. KJ is a unicellular green microalga that accumulates abundant lipids when cultured under nitrogen-deficient conditions (KJ1) and high nitrogen levels when cultured under nitrogen-sufficient conditions (KJ2).

Balancing High Yield and Metabolic Health in Dairy Ruminants: The Central Hub Role of the Rumen Microbiota

Veterinary Sciences
Modern dairy production has greatly increased milk yield, but high productivity is often accompanied by greater metabolic pressure, particularly during the transition period.

Harnessing the early-life gut microbiome for sustainable ruminant production

Animal Microbiome
The gut microbiome is a dynamic and complex ecosystem that plays an important role in determining ruminant health, productivity, and environmental footprint. Its plasticity during early life presents a critical window for potential programming of long-term physiological and functional capacities, with early interventions demonstrating greater ...

Preliminary Study on the Impact of Ruminal Ciliate Inoculation in Fauna-Free Conditions on the Ruminal Fermentation and Ciliate–Prokaryote Association In Vitro

Fermentation
Ruminants rely on the rumen for the anaerobic fermentation of fibrous plant materials, facilitated by a complex microbial community of bacteria, archaea, fungi, and ciliates.
