Особое место среди злаковых культур в качестве компонента комбикормов занимает рожь. Для производства комбикормов может быть использована рожь, непригодная для продовольственных целей, но вполне пригодная для кормления сельскохозяйственных животных.Методы. Было сформировано 4 группы бычков на доращивании и разработаны 4 рецепта комбикормов-концентратов с различной нормой ввода ржи (0, 20, 30, 40%). Продолжительность опыта составила 135 дней. Для выяснения влияния состава комбикормов на потребление кормов проводили ежедневный групповой учет кормления. Подопытных животных взвешивали каждые 30 дней, то есть ежемесячно. Для выявления влияния испытуемого зерна (ржи) напотребление основного сбалансированного рациона вели записи по учету потребленных кормов и их остатков на следующий день. Изменение состава рациона проводили каждый месяц после взвешивания животных. В течение всего научно-хозяйственного опыта вели учет поедаемости.Результаты. Комбикорма, приготовленные по разработанным рецептам, позволяют балансировать кормление подопытных бычков, которые будут выращиваться для получения говядины по имеющимися на сегодняшний день детализированными нормами кормления, при сравнительно невысокой удельной массе концентрированных кормов. Включение в состав комбикормов от 20 до 40% ржи не снижает сбалансированности рациона животных в опыте. Валовый прирост живой массы и прирост за сутки у подопытных бычков первых трех групп различался несущественно. Животные из IV группы, которым скармливали комбикорм с 40% ржи, уступали контрольным животным по всему приросту на 5,6 кг, по среднесуточному приросту — на 43 г. На единицу прироста живой массы (1 кг) расходовалась 5,87–6,03 ЭКЕ.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Rye occupies a special place among cereals as components of compound feeds. Rye, unsuitable for food purposes, but quite suitable for feeding farm animals, can be used for the production of compound feeds.Methods. To solve the problems, 4 groups of gobies were formed for rearing and 4 recipes of compound feed concentrates with different rye input rates were developed (0, 20, 30, 40%). The duration of the experiment was 135 days. To find out the effect of the compound feed composition on feed consumption, daily group feeding accounting was carried out. Experimental animals were weighed every 30 days, that is, monthly. To identify the effect of the tested grain (rye) consumption of the basic balanced diet, records were kept on the account of the feed consumed and their residues the next day. During the entire scientific and economic experience, feedabilitywas recorded.Results. Studies have shown that compound feeds prepared according to the developed recipes allow balancing the feeding of experimental bulls that will be raised to produce beef according to the detailed feeding standards available today, with a relatively low specific gravity of concentrated feeds. The inclusion of 20 to 40% rye in the composition of compound feeds does not reduce the balance of the diet of animals in the experiment. The gross increase in live weight and the increase per day in the experimental bulls of the first three groups did not differ significantly. Animals from group IV, which were fed compound feed with 40% rye, were inferior to control animals by 5.6 kg in total growth, in an average daily increase — by43 g. 5.87–6.03 ECU was spent per unit of live weight gain (1 kg).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молодняк</kwd><kwd>доращивание</kwd><kwd>рожь</kwd><kwd>комбикорм</kwd><kwd>рацион</kwd><kwd>прирост</kwd><kwd>затрата кормов</kwd><kwd>питательные вещества</kwd><kwd>структура рациона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>young animals</kwd><kwd>rearing</kwd><kwd>rye</kwd><kwd>compound feed</kwd><kwd>diet</kwd><kwd>growth</kwd><kwd>feed consumption</kwd><kwd>nutrients</kwd><kwd>diet structure</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">Аникин А.С., Некрасов Р.В., Головин А.В., Дуборезов В.М., Чабаев М.Г.
