Abstract. The purpose In the light of current agricultural development trends aimed at the production and increase of environmentally friendly sheep products, breeding methods need to improve approaches based on the use of new, more subtle bioinformatic techniques. Scientific novelty of the work lies in the fact that, for the first time, comprehensive studies have been conducted that make it possible, through the use of bioenergetic parameterization of superficially localized biologically active centers, to evaluate breeding indicators of the productive potential of reproducing sheep of different ages. Based on the above, an information model of the process of assessing the productive potential of reproducing sheep of different ages will be compiled. The purpose of the research perform bioenergetic parameterization to create a digital model for estimating the wool productive potential of reproducing sheep of different ages. Methods. The research was carried out at the Navesnoye laboratory from 2016 to 2022. The object of the research were sheep and queens of sheep of the North Caucasian breed. The experiments used 136 heads of queens and 9 heads of breeding sheep aged from 1.5 to 3.5 years. Bioelectric potential levels were measured using an ELAP-type device in superficially localized biologically active centers (SLBAC) № 13, № 15, № 64, № 65, № 80 for three consecutive days with the calculation of averages. Results. The productive indicators of breeding sheep and ewes are interrelated with the levels of bioelectric potentials of their sheep; parameterization of the levels of bioelectric potentials of sheep of the North Caucasian breed makes it possible to evaluate the breeding and genetic parameters of wool productivity of reproducing sheep and to form optimal options for the selection of parental pairs. These patterns can be successfully used in breeding work with sheep of the North Caucasian breed in the assessment of their breeding heritable productivity indicators and in the selection of parental pairs. The developed digital model of bioinformatic assessment of sheep productivity indicators makes it possible to predict the degree of heritability of productive indicators with a high degree of probability and increase the profitability of the industry.
