Discussion

Observational analysis highlighted the variability of milk yield and components in Holstein cows, indicating genetic and environmental influences.

The modeled lactation curves achieved a high accuracy of 93.5%, showcasing their potential for dairy science.
Key biomarkers, including acetone, BGB, and urea, were assessed in over 11,500 Holstein cows, revealing important metabolic insights.
Determination coefficients for protein content during lactation reached 83.9%, while fat content demonstrated lower accuracy at 63.7%.
Dynamic analysis of milk yield changes emphasizes the importance of regression equations to assess herd functional qualities.

Karlikova et al. (2025) studied this question.
