Discussion

Observational study shows that factors like insemination age and live weight impact milk yield in Holstein cows.

Milk productivity significantly varies with age at first insemination, with optimal results seen at 12.5 months.
Heifers with a live weight of 376 kg yield more milk, fat, and protein, underscoring the importance of proper weight.
Cows calving in autumn demonstrate the highest milk productivity, indicating seasonal effects on dairy yield.
Strong correlations exist between age, weight, and milk yield traits, emphasizing the need to consider these factors together.

Шишкина et al. (2025) studied this question.
