Overview

Observational analysis reveals age at insemination and calving season significantly affect milk productivity in dairy cows.

Key Points

  • The highest milk productivity observed was 10339 kg for cows calving in autumn, indicating seasonal influences.
  • Animals inseminated at 12.5 months yielded the most milk fat and protein, suggesting optimal insemination timing.
  • Lower live weights at first insemination correlated with decreased milk yields, emphasizing the importance of growth conditions.
  • Strong correlations were found between increasing age at first insemination and lower milk productivity outputs.
