Milk traits as indicators of energy status in early lactation dairy cows from two farms
The aim of this study was (1) to evaluate the relationship between serum nonesterified fatty acids (NEFA) concentrations and selected milk components in Holstein cows from two farms in the first 5 weeks of lactation, and (2) to find a model predicting serum NEFA concentrations from milk traits valid for both herds. We used serum NEFA concentration as a biomarker to assess the energy status of animals.
