FIELD: agriculture.
SUBSTANCE: invention relates to the field of agriculture. Method to detect high-milk cows at early age, differing by the fact that the value of cortisol is detected in blood serum in nine-month heifers, and animals having cortisol concentration of more than 5.65 nmole/l are related to high-milk cows.
EFFECT: method makes it possible to quickly and accurately forecast future milk productivity of cows at early age.
