Установлена взаимосвязь индексной оценки с фактическими показателями селекционируемых признаков. Использование отобранных по комплексным индексам лучших хряков (5-10%) и свиноматок (10-30%) позволяет получить ремонтный молодняк хрячков со среднесуточным приростом выше родителей на 11-27 грамм, толщиной шпика на 0,12-0,14 мм меньше, с многоплодием на 0,03-0,09 головы выше средних значений исходной опытной популяции, с незначительным или нулевым ростом показателей массы гнезда при рождении и среднего веса поросят к отъему. Прогнозируемое превосходство свинок над средними показателями родителей составит по среднесуточному приросту 11-16 грамм, по толщине шпика - (-0,12) мм, по многоплодию 0,01-0,03 головы в год.</p></abstract><trans-abstract xml:lang="en"><p>The research to be predict the effect of selection at different intensity of selection according to complex breeding indices. The effect of selection of population of pigs of maternal breeds of the republic at different intensity of selection and matching of prospective fathers and mothers based on index selection. Correlation between the index score and the actual indicators of the selected traits has been established. Use of the best boars (5-10%) and sows (10-30%) selected according to the complex indices makes it possible to obtain replacement young boars with the average daily weight gain of 11-27 grams higher than their parents, and backfat thickness of 0.12-0.14 mm less, with multiple pregnancy rate of 0.03-0.09 animals higher than the average values of the initial experimental population, with insignificant or zero growth in parameters of litter weight at birth and the average weight of piglets by weaning. The predicted superiority of gilts over the average indicators of parents will be 11-16 grams in average daily weight gain, in backfat thickness - (-0.12) mm, in multiple pregnancy rate - 0.01-0.03 animals annually.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эффект селекции</kwd><kwd>селекционный индекс</kwd><kwd>экономическая ценность</kwd><kwd>свиньи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breeding effect</kwd><kwd>breeding index</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.
