Functional Changes of the Community of Microbes With Ni-Dependent Enzyme Genes Accompany Adaptation of the Ruminal Microbiome to Urea-Supplemented Diets [PDF]
Frontiers in Microbiology, 2020 Urea is an inexpensive non-protein nitrogen source commonly supplemented to the diets of ruminants. It is cleaved to ammonia by bacterial ureases, which require Ni as a catalyst for ureolysis.

Differential Dynamics of the Ruminal Microbiome of Jersey Cows in a Heat Stress Environment [PDF]
Animals, 2020 The microbial community within the rumen can be changed and shaped by heat stress. Accumulating data have suggested that different breeds of dairy cows have differential heat stress resistance; however, the underlying mechanism by which nonanimal factors

Ruminal microbiome-host crosstalk stimulates the development of the ruminal epithelium in a lamb model [PDF]
Microbiome, 2019 Background The development of the rumen is an important physiological challenge for young ruminants. Previous studies have shown that starter feeding can effectively facilitate the growth and development of the rumen in ruminants.

Induction of Subacute Ruminal Acidosis Affects the Ruminal Microbiome and Epithelium
Frontiers in Microbiology, 2016 Subacute ruminal acidosis (SARA) negatively impacts the dairy industry by decreasing dry matter intake, milk production, profitability, and increasing culling rate and death loss.
