FIELD: agriculture.
SUBSTANCE: method lies in the following: every year in herd of fresh cows group of animals is selected with length of service-period up to 30 days. From said group selected are highly-productive animals whose index of milk quantity during the first month of lactation is one sigma:
above the average group index, where 
is the average sign value, σ is average quadratic deviation.
EFFECT: method allows to predict quickly and accurately during the first lactation month future life-long productivity and longevity of cows and form bull-producing pedigree nucleus at farms with different productivity level.
