Canonical Correlation of Milk Composition Parameters and Blood Biomarkers in High-Producing Dairy Cows During Different Lactation Stages

Abstract

Key findings of our study included strong positive relationships between lactation stages and blood biomarkers like glucose and cholesterol, as well as milk protein levels. Blood biomarkers such as triglycerides, magnesium, and urea showed significant correlations with various milk parameters. Canonical correlation analysis identified strong relationships between blood biomarkers and milk composition, with blood triglycerides and milk urea being the most influential variables. The presented findings suggest that understanding these correlations can help improve dairy cow management and milk production strategies.
