Research methods - zootechnical (assessment of qualitative and quantitative performance indicators); methods of modeling and forecasting based on the use of informational and statistical multidimensional models. The results of the conducted scientific and research work: the selection of the Holstein breed is possible to increase the productivity of animals with a lower milk yield without impairing the reproductive capacity, and for the breeding of highly productive cows, use those that differ by plus-deviations from the average level according to "A" and KVZ; with increasing animal age (i.e. lactation number) estimates of the informational fractal dimension (FD1) had a probable tendency to decrease, which indicates an increase in the degree of fractality associated with an increase in the role of selection work with animals of this herd as a result of culling after I-II - th lactation of cows with an unsatisfactory level of milk productivity; the use of fractal analysis to study the mechanisms of formation of signs of milk productivity of dairy cows made it possible to determine the influence of both their origin and generation (in terms of mother - daughter); estimates of the repeatability coefficient for the traits characterizing the nest size of BBP sows were generally low - 0.217 ± 0.037, 0.141 ± 0.032 and 0.073 ± 0.027 for the total number of piglets, fertility and number of piglets at weaning, respectively.
