BIOMETRIC MODELS AND SELECTION-GENETIC PARAMETERS OF SELECTABLE TRAITS OF BREEDING PIG POPULATION
Abstract
The article contains the materials of research, the purpose of which was to develop biometric models and to carry out the calculation of selection-genetic parameters of selectable traits of breeding pig population. Based on variance analysis of systemic environmental factors, optimal forecast equations (biometric models) for the development of selectable traits of breeding pigs were elaborated. In the course of variance analysis of fixed factors of reproductive traits of maternal breed sows, it was found that the average values of all traits in the context of factors had significant differences in all studied variants of models. On the basis of the developed optimal statistical models describing the development of selectable traits, the components of the total variance, as well as the inherited (additive) genetic part of the total phenotypic variability - inheritance coefficients - were determined.
