Currently, the assessment of the breeding value of livestock provides for new approaches to determine the genetic qualities of animals that sustainably transmit to offspring. This is achieved by using the phenotypic data of the ancestors, the closest lateral relatives, as well as the animals themselves and their descendants, which, according to all canons, is facilitated by the so-called BLUP methodology. The purpose of the study is to establish the estimated breeding values of Auliekol cattle by productive indicators. For the Auliekol cattle breed, the estimated breeding values in terms of live weight at birth varied in the range: The first year from-3.47 to ++9.03; the second year-5.18 to +12.60; the third year-5.22 to +12.52; in 2021-5.18 to +12.52. The percentile distribution of the calculated EBV of the live weight of the Auliekol cattle breed at weaning in 2018 varied in the range from-19.76 to +53.63, in 2019-23.88 to +63.65, in 2020-24.33 to +63.01, in 2021-23.58 to +62.53. The EBV in terms of live weight at one year of age in 2018 varied from-39.37 to +71.86, in 2019-34.44 to +90.83, in 2020-33.34 to +90.24, in 2021-34.21 to +90.81. The estimated breeding value in terms of live weight for adult animals in 2018 ranged from-43.11 to +57.72, in 2019-97.40 to +105.45, in 2020-95.57 to +106.99, in 2021-176.40 to +110.53. The EBV for the indicator of the milking capacity of mothers of the Auliekol breed in 2018 ranged widely from-28.89 to +65.89, in 2019-26.18 to +52.71, in 2020-24.01 to +51.55, in 2021-23.67 to +52.75. For the Auliekol cattle breed, the EBV in terms of the average daily gain from birth to 12 months of age is in the range of the minimum indicator from-198.29 to-242.68, the maximum indicator from +235.88 to +348.71.
