The metabolomics study was designed to investigate the effects of feeding cows with Hermetia illucens larvae oil on rumen fluid profiles.

From an animal production and health perspective, our understanding of the metabolites in ruminant biofluids, particularly rumen fluid across different host species is poorly understood. Metabolomics is a powerful and sensitive approach for investigating low molecular weight metabolite profiles p...

Background: High-yield dairy cows are usually accompanied with lower milk fat (MF) rate, with huge variations in MF contents among individuals. The potential mechanisms of key microorganisms, their genes and metabolites participate in MF synthesis are still not well understood. By selec...

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. Phages have been shown to affect&nbs...

Microplastics pollution is prevalent in livestock environments, especially in ruminant feed. Exposure to microplastics can damage the gastrointestinal barrier, alter microbiota, and lead to organ damage. Despite its impact on cattle farming and potential human health risks, the effects of micropl...

BACKGROUND: Lactation is extremely important for dairy cows; however, the understanding of the underlying metabolic mechanisms is very limited. This study was conducted to investigate the inherent metabolic patterns during lactation using the overall biofluid metabolomics and the...

Background

Persistent productivity and productive lifespan determine the lifetime output of dairy cows and influence overall herd profitability. The composition and metabolic activity of the gastrointestinal microbiota of dairy cows influence persistent productivity. However,...
