“…Previously, the indices of the breeding value of cattle of the Hereford breed of the Kazakh population were determined using generally accepted research methods. At the same time, it was found that the share distribution of accuracy for the calculated breeding value index in 2021 according to the productive indicators of Hereford breed animals contains zero values for the most part for the indicators of dairy cows (Bissembayev et al, 2022). Similar data were obtained by us for the Auliekolsky breed of cattle.…”

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.
