Кролиководство сегодня является перспективной отраслью мясного животноводства, основная продукция которой – высококачественное диетическое мясо. В статье представлены результаты изучения возрастной динамики прироста живой массы гибридного молодняка кроликов на откорме при включении в их рацион разных концентраций мультивитаминного комплекса «НутриСел». Научно-хозяйственный эксперимент проводился в условиях кролиководческой фермы ООО «Русский кролик» Костромского района Костромской области. Лучшие результаты были получены в опытной группе № 2, животным которой скармливали 0,5 мл/гол/сут.: достоверная разница живой массы молодняка кроликов на откорме составила 3,06 кг (Р≤0,05), что на 0,11 кг (3,59%) больше контрольной. Абсолютный прирост имел также преимущество перед аналогами контрольной и опытных групп № 1 и № 3 в среднем на 20 г (6,4%; Р≤0,01). Среднесуточный прирост был выше на 2,64 г (5,77%; Р≤0,01) по сравнению со сверстниками контрольной группы. Относительный прирост живой массы кроликов превосходил контрольную группу на 0,14% (1,41%). При этом сохранность молодняка составила 100%. С целью увеличения прироста живой массы рекомендуем включать в рацион кормления кроликов мультивитаминный комплекс «НутриСел» в количестве 0,5 мл/гол/сут. в течение 3–5 дней с момента отлучки.</p></abstract><trans-abstract xml:lang="en"><p>The problem of increasing the production of high-quality, profitable and in-demand livestock products on the market is acute at the present stage of agricultural development. Rabbit breeding today is a promising branch of beef farming, the main product of which is high-quality dietary meat. The article presents the results of a study of age dynamics and live weight gain of hybrid young rabbits for fattening when different doses of the multi-vitamin complex “NutriCel” are included in their diet. From August to October 2023, a scientific and economic experiment was carried out on the territory of the rabbit breeding farm of Russian Rabbit LLC, Kostroma district, Kostroma region. As a result of the scientific experiment, the following data were obtained: the best results were obtained in experimental group No. 2, the animals of which were fed 0.5 ml/animal/day: a significant increase in live weight of young fattening rabbits was 3.06 kg (P≤0.05), which is 0.11 kg (3.59%) more than the control. The absolute increase had an advantage over the analogues of the control and experimental groups No. 1 and No. 3 by 20 g (6.4%; P≤0.01). The average daily gain was higher by 2.64 g (5.77%; P≤0.01) compared with peers in the control group. The relative increase exceeded the control by 0.14% (1.41%). At the same time, the safety of the young animals was 100%. In order to increase live weight gain, we recommend including the multi-vitamin complex “NutriCel” in the diet of rabbits with a dosage of 0.5 ml/bird/day for preventive purposes within 3–5 days from the moment of weaning. It showed a positive effect not only on the zootechnical parameters of young rabbits, but also on immunity in general.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кролики</kwd><kwd>кормление</kwd><kwd>добавка</kwd><kwd>концентрация</kwd><kwd>рост</kwd><kwd>молодняк</kwd><kwd>содержание</kwd><kwd>сохранность</kwd><kwd>технология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rabbits</kwd><kwd>feeding</kwd><kwd>additive</kwd><kwd>concentration</kwd><kwd>growth</kwd><kwd>young</kwd><kwd>maintenance</kwd><kwd>preservation</kwd><kwd>technology</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">Алексеева Е.А.
