The expediency of improving the indicators of judgment assessments of individual breeding characteristics of the Hereford cattle breed is justified. The proposed method of selecting cows according to a complex evaluation indicator is based on the principle of a point assessment with the correction of the selection significance of the absolute value of some economically useful characteristics that are definitely related to the economy of animal breeding. At the same time, it is characterized by the Breeding Value Index (BVI), which allows you to complete a selection group of cows in breeding herd with breeding value from 70 points and above. The main values of constructed index must select or create such genotypes that would combine the most important and desirable combinations of breeding traits. The method is universal for cows of different breeds, types, herds, provides breeding and formation of more highly productive and technological animals on the basis of meat productivity.
