С увеличением поголовья пушных животных необходимо производство комбикормов, обеспечивающих высокое качество пушнины при минимальных затратах корма. Для пушных зверей разработаны рецепты комбикормов с содержанием жира 20 % и выше. Целесообразным является скармливание корма в виде гранул, выработанных по технологии, одним из этапов которой является процесс гранулирования комбикормов с повышенным содержанием жира при обоснованных параметрах работы пресса-гранулятора. Для определения оптимальных параметров гранулирования проведены исследования процесса с применением метода статистического планирования многофакторного эксперимента. В качестве факторов, влияющих на рассматриваемый процесс, были выбраны: количество введенного жира, расход пара, зазор между валком и матрицей пресса. Критерием оценки влияния выбранных параметров служили удельный расход энергии и крошимость, позволяющие адекватно оценить эффективность процесса. Полученные данные свидетельствовали, что процесс гранулирования комбикормов при оптимальных параметрах позволяет получать гранулы, качество которых отвечает требованиям стандарта. Все полученные данные лежали в пределах рассчитанных доверительных интервалов параметров оптимизации. Исследовали изменение показателей качества полученного гранулированного комбикорма при хранении. Изменения качества гранулированного комбикорма при хранении свидетельствовали, что значения общей кислотности и кислотного числа жира существенно выросли после двух месяцев хранения вследствие гидролиза жира в условиях свободного доступа кислорода. Значение перекисного числа жира, отражающего глубину окислительных изменений в комбикорме, после двух месяцев хранения резко возрастало. Содержание витаминов А и Е при хранении комбикормов в течение 45 дней в летний период составили соответственно 12,3 % и 10,5 % от исходных значений. Рекомендуемый срок хранения гранулированных комбикормов с повышенным содержанием жира в зимне-весенний период составляет 60 суток, в летний – 45 суток.</p></abstract><trans-abstract xml:lang="en"><p>Currently, fur farming products are becoming more and more in demand. With the increase in the number of fur-bearing animals, it is necessary to produce compound feeds that provide high quality furs with minimal feed costs. Compound feed recipes with a fat content of 20% and higher were developed for fur animals. Feeding fodder in the form of granules produced by the technology, one of the stages of which is the process of granulating compound fodders with a high fat content with reasonable operating parameters of the granulator press, is expedient. Process studies using the method of statistical planning of a multivariate experiment were carried out to determine the optimal granulation parameters. The following factors influencing the process under consideration were chosen: the amount of added fat, the steam consumption, the gap between the roll and the press die. Specific energy consumption and crumbling served as criteria for assessing the influence of the selected parameters, which make it possible to assess adequately the efficiency of the process. The data obtained showed that the process of pelleting compound feed at optimal parameters makes it possible to obtain pellets, the quality of which meets the requirements of the standard. All the data obtained were within the calculated confidence intervals of the optimization parameters. The change in the quality indicators of the obtained granulated compound feed during storage was also investigated in the work. Changes in the quality of granulated compound feed during storage testified that the values of total acidity and acid number of fat increased significantly after two months of storage due to hydrolysis of fat in conditions of free oxygen access. The value of the peroxide number of fat, which reflects the depth of oxidative changes in the compound feed, increased sharply after two months of storage. The content of vitamins A and E during the storage of compound feed for 45 days in summer was 12.3% and 10.5% of the initial values, respectively. The recommended shelf life of granulated feed with a high fat content in winter-spring period is 60 days, in summer - 45 days.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>звероводство</kwd><kwd>гранулированные комбикорма</kwd><kwd>статистическое планирование</kwd><kwd>показатели качества</kwd><kwd>хранение комбикормов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fur farming</kwd><kwd>granulated feed</kwd><kwd>statistical planning</kwd><kwd>quality indicators</kwd><kwd>compound feed storage</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Воронежский государственный университет инженерных технологий</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Паркалов И.В.
