The latest 2026 August Interbull evaluation confirms that Norwegian Red has strengthened its position as the leading red dairy breed for milk production worldwide. Long recognized for excellence in fertility and health, Norwegian Red now also demonstrates a clear advantage in production performance compared with other red dairy breeds.
Interbull evaluations compare the genetic performance of daughter-proven bulls across multiple countries, providing one of the most reliable international benchmarks for dairy cattle genetics. According to the August 2026 Interbull evaluation, Norwegian Red demonstrates a leading level of genetic progress in production traits among red dairy breed populations (the technical term Interbull uses for the group of bulls representing each breed in a given evaluation).
For the 2021 birth cohort, Norwegian Red bulls achieved a milk yield genetic level that was 18 index points above the average for other Scandinavian Red breed bulls and 20 index points above red breed bulls from other countries, highlighting the strong and consistent genetic progress of the Norwegian Red population.
Genetic Advantage Translates into Farm Profitability
The practical value of genetic progress becomes clear when measuring on-farm performance.
Interbull estimates that offspring from bulls with a 20-point index advantage will produce approximately 436 kg more milk per cow per year than offspring from lower-ranking bulls. Relative to the average Norwegian Red lactation yield of around 8,100 kg, this represents an increase of roughly 5%. Translated into economic terms, this production difference represents a meaningful annual gain per cow. In Norway, for example, with a milk price of approximately NOK 7.5 per kilogram, this translates to an additional value of around NOK 3,270 per cow annually, or roughly €300 per cow annually — giving an indicative sense of scale even though actual milk prices vary by market.
For dairy farmers, this means that selecting Norwegian Red genetics delivers measurable economic benefits while maintaining the breed's established strengths in health and fertility globally.

Proven by Data
Norwegian Red's reputation has traditionally been built on strong fertility and health performance. The latest Interbull results show that the breed is now equally distinguished by its progress in milk production. No other red dairy breed population demonstrates greater genetic advancement in production traits, reinforcing Norwegian Red's position as a breed that combines efficiency, functionality and profitability globally.
For dairy producers seeking sustainable genetic progress, the message from the latest evaluation is clear: Norwegian Red delivers a measurable production advantage backed by internationally recognized data.
