Metabolomics reveals potential biomarkers in the rumen fluid of dairy cows with different levels of milk production [PDF]
Asian-Australasian Journal of Animal Sciences, 2020 Objective In the present study, an liquid chromatography/mass spectrometry (LC/MS) metabolomics approach was performed to investigate potential biomarkers of milk production in high- and low-milk-yield dairy cows and to establish correlations among rumen

Investigating cow−calf contact in a cow-driven system: performance of cow and calf [PDF]
Journal of Dairy Research, 2021 AbstractIn this research communication we describe the performance of dairy cow−calf pairs in two cow-driven CCC-systems differing in cows' access to the calves through computer-controlled access gates (smart gates, SG). We investigated cows' machine milk yield in the automatic milking system (AMS), calf growth, and intake of supplemental milk and ...
