Abstract

The paper summarizes the results of additional information resources of multidimensional statistical analysis resources on the basis of research carried out by the authors. For the large white breed the authors made the equations of multiple regression for the initial forecast of some lifetime parameters of sows, taking into account the obtained reliable values of correlation coefficients on the basis of development at the beginning of animal application. The obtained parameters of phenotypic correlations highlight the possibility of using dairy capacity and number of cows in the herd when weaning to predict the weight of the piglets’ nest aged 2 months within the limits of the corresponding (1, 3, 6) sows’ farrows. The results of using regression equation show that the next farrowing or lifetime productivity of a group of pigs can be estimated by means of several indicators of any farrowing. The article outlines that selection index inheritance coefficient calculated by the method of dispersion analysis of half-sibs according to male (fathers) was 0.41±0.04 (P<0.001). This confirms complex improvement of the the reproductive properties of herd sows by means of the index. This is proved by by the results of ranking the parameters of the investigated features after modeling of 50% of the selection. Similar modeling of dealing with the results related to assessment of fattening and meat qualities of young Kemerovo breed outlines a tendency, which is common for both reproductive qualities of sows and parameters of control fattening. When selecting according to one single feature, the authors observed the highest (lowest) parameters in comparison with the analyzed characteristics that were not subject to selection. However, the index selection prevailed in terms of the set of features.
