Гомозиготные хряки по аллелю В способствуют сокращению периода откорма получаемого молодняк на 7 дней и увеличению среднесуточных приростов на 25 г. Ремонтный молодняк, отцы которого имели генотип ВВ, отличается умеренной осаленностью (20,3-24,0 мм толщина шпика) и повышенной мясностью - 47,5 % (прибором Piglog-105).</p></abstract><trans-abstract xml:lang="en"><p>It is determined that most part of boars (80 %) are represented by AA genotype of gene-marker IGF-2 (intron 2), and the frequency of allele A - 0.87. Homozygous boars by B allele promote reducing the fattening period of the produced young animals by 7 days and increase in average daily gain by 25 g. Replacement young animals with fathers that had BB genotype is peculiar of moderate fat content (20.3-24.0 mm backfat thickness) and high meat content - 47.5 % (by unit Piglog-105).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>селекция</kwd><kwd>генотип</kwd><kwd>ген-маркер IGF-2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>selection</kwd><kwd>genotype</kwd><kwd>gene marker IGF-2</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">Достижения и перспективы использования ДНК-технологий в свиноводстве : моногр. / Т.
