В процессе исследований определены селекционно-генетические параметры белорусской популяции свиней пород ландрас и йоркшир. Рассчитана экономическая значимость селекционируемых признаков. Разработаны экономические селекционные индексы оценки хряков и свиноматок, включающие признаки собственной продуктивности и репродуктивные признаки. Точность индексов составила 0,617-0,783 для индексов состоящих из признаков собственной продуктивности и комбинированных, и 0,349 для индексов репродуктивных признаков свиноматок.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>селекционный индекс</kwd><kwd>агрегатный генотип</kwd><kwd>экономическая ценность</kwd><kwd>свиньи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breeding index</kwd><kwd>aggregate genotype</kwd><kwd>economic value</kwd><kwd>pigs</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dekkers, J.C.M., Gibson, J.P., Bijma, P, and van Arendonk, J.A.M. 2005.
