Implication

Randomized trial evaluates production and fertility traits in dairy farms, suggesting environmental adaptations may enhance outcomes.

Key Points

The study aims to assess the impact of herd and environmental factors on production and reproductive traits in pasture-based dairy systems in Argentina.
Analyzed 46,588 lactations from 19,936 cows across 16 herds between 2010 and 2023.
Evaluated traits including milk yields, calving intervals, and reproductive performance alongside environmental influences.
Conducted variance component analysis to determine the influence of cow effects on milk and fertility traits.
Calving in autumn-winter led to better production and fertility, coinciding with lower heat stress.
Observed stabilization in milk yield and limited progress in fertility from 2010 to 2023, with improvements in 2020-2023.
Cow effects explained 16-19% variance in production traits and 8-11% in fertility traits.
