Abstract excerpt
Milk urea nitrogen, the primary form of nonprotein nitrogen (N) in milk, is an indirect indicator of N metabolism in dairy cows. The MUN concentrations are modulated by various factors, including dietary composition, physiological status, and environmental conditions. However, the potential roles of host gut microbiota and metabolome in the development of distinct MUN phenotypes remain insufficiently elucidated....
