Проведение голштинизиции выявило ряд проблем в разведении помесных животных, в том числе снижение продуктивного долголетия коров. Это ставит новые задачи по решению вопросов воспроизводства стада и выращиванию ремонтного молодняка. Изучение взаимосвязи динамики живой массы по периодам роста в разрезе линий молодняка актуально и имеет практическое значение. В результате проведенных исследований установлено, что телки линии Вис Бэк Айдиала 1013415 по живой массе во все периоды превосходят своих сверстниц из линии Рефлекшн Соверинга 198998, несмотря на то, что они выращивались в одинаковых условиях содержания и кормления и при рождении имели практически одинаковую живую массу. В 6-, 10- и 12-месячном возрасте разница по живой массе оказалась достоверной при p ≤ 0,05– 0,01 в пользу телок из линии Вис Бэк Айдиала 1013415. По периодам роста установлена положительная сопряженность с изменением живой массы. Корреляция между живой массой по периодам и возрастом первого осеменения отрицательная. </p></abstract><trans-abstract xml:lang="en"><p>In Sverdlovsk region the Ural type of Holsteinized black-and-white cattle is raised and used. Admixing of Holstein line revealed a number of problems in the breeding of crossbred livestock, including decrease of the cows’ productive longevity. This poses new challenges for solving the issues of the herd reproduction and growing of young replacement livestock. The research of correlation between the dynamics of live weight gain by periods of growth along the young livestock lines is relevant and has practical significance. In result of the research it was found that the heifers of Vis Back Ideal 1013415 line outcompeted their peers from the Reflection Sovering line 198998 in terms of live weight in all periods, provided that they were raised under the same conditions, same feeding and same care; moreover all heifers had practically the same live weight at birth. At 6, 10 and 12 months of age, the difference in live weight was significant at p ≤ 0.05–0.01 in favor of heifers of the Vis Back Ideal 1013415 line. According to the periods of growth, a positive conjugation of body weight changes was revealed. The correlation between live body weight by periods and the age of the first insemination is negative. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>коровы</kwd><kwd>ремонтный молодняк</kwd><kwd>живая масса</kwd><kwd>продуктивность</kwd><kwd>периоды роста</kwd><kwd>мясное животноводство</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cows</kwd><kwd>replacement livestock</kwd><kwd>live weight</kwd><kwd>productivity</kwd><kwd>growth periods</kwd><kwd>beef farming</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">Sheveleva O.M., Smirnova T.N., Sukhikh N.S.
