New research from New Zealand’s dairy sector highlights that improving herd fertility is not just a breeding goal but a critical driver of milk production, farm workload, and overall costs, with findings showing that the timing of conception has a direct impact on long-term farm performance.
The study found that cows failing to conceive early in the mating period tend to calve later, resulting in lower milk production early in lactation and a higher likelihood of being carried over to the next season, which over time reduces lifetime productivity while increasing labour demands and operational costs.
Researchers emphasised the growing importance of fertility breeding value (BV) as a key management tool, enabling farmers to select cows with better reproductive traits that resume cycling sooner, conceive more reliably, mature earlier, and remain productive longer, ultimately improving herd stability and economic outcomes.
The findings, part of the Resilient Dairy Programme—a collaboration between DairyNZ, NZ Animal Evaluation, LIC, and the Ministry for Primary Industries—also point to future innovation areas such as improved pregnancy diagnosis and wearable technology to track reproductive cycles, reinforcing fertility as a central lever for boosting efficiency, sustainability, and profitability in modern dairy systems.
