Article Synopsis
- This study examines the impact of increasing temperatures on dairy cattle fertility and production, focusing on Holstein and Montbeliarde breeds.
- Genetic correlations showed that while fertility is generally stable across different temperature-humidity conditions, the best reproducers in Holsteins are more negatively impacted by heat stress than in Montbeliarde, highlighting breed differences.
- Overall, rising temperatures are not expected to worsen the trade-off between production and fertility, but the top-producing animals today may face greater challenges due to heat stress in the future.
In the long term, resilient animals are able to maintain their normal biological processes when confronted with environmental perturbations, reducing their risk of being culled. Therefore, longevity can be proposed as an indicator of long-term resilience. Decisions to remove a given dairy cow from the herd are mainly related to low milk production (i.
