DEVELOPMENT OF ECONOMIC MULTIPLE TRAIT SELECTION INDICES
Abstract
The paper presents the materials of the work with the purpose to develop the optimal economic complex indices for maternal pig breeds. In the course of the research, the selection and genetic parameters of the Belarusian population of Landrace and Yorkshire pigs were determined. The economic significance of the selected traits has been calculated. Economic selection indices for assessing boars and sows have been developed, including parameters of their self-performance and reproductive traits. The accuracy of the indices was 0.617-0.783 for indices consisting of parameters of self-performance and combined, and 0.349 for indices of reproductive traits of sows.
