FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular dairy cattle breeding. The method consists in the fact that on the 30th day after the first calving the size and density of the ovaries is determined in cows using rectal palpation (or other method), and the animals with atrophy of the right ovary are culled from the herd.
EFFECT: method enables to predict quickly and accurately a month after first calving the future milk production, reproductive ability of cows.
