Представленные в отечественной и зарубежной научной литературе модели направлены на оценку выделения различных газов преимущественно от взрослого поголовья. Поэтому разработка модели расчета выбросов КАГ при выращивании молодняка крупного рогатого скота в условиях неопределенности, возникающей при формировании воздушной среды в животноводческом помещении, является актуальной. По результатам проведенных теоретических исследований предложена структурная схема оценки уровня выбросов климатически активных газов из помещений для содержания молодняка, ключевым элементом которой выступает математическая модель расчета этих эмиссий. В ее основу положены разработанные зависимости для расчета объемов выбросов CO2, CH4, NH3 и H2S с учетом результатов мониторинга и технологических параметров. Экспериментальная информация формировалась на основе данных о параметрах воздушной среды помещения для выращивания молодняка КРС и внешней среды с применением специально спроектированной мобильной платформы многоуровневого контроля концентрации климатически активных газов. Были изучены параметры воздушной среды в помещении для содержания 518 гол. молодняка КРС в возрасте от 3,2 до 9,4 мес. Полученные данные позволили провести моделирование и расчет объемов выбросов климатически активных газов в зависимости от возраста животных. Выбросы в целом по исследуемому помещению составили: СО2 – 781,0 кг/сут; CH4 – 24,9 кг/сут; NH3 – 1,1 кг/сут; H2S – 0,003 кг/сут. Полученные результаты будут использованы при разработке рекомендаций к технико-технологическим решениям по снижению эмиссии в окружающую среду климатически активных газов из животноводческих помещений для содержания молодняка КРС.</p></abstract><trans-abstract xml:lang="en"><p>One of the most significant and complex processes in dairy farming is herd reproduction. This process involves rearing healthy calves and heifers, which, in turn, are a source of climate-active gases. The models from existing national and foreign scientific literature aim at assessing the release of various gases mainly from adult livestock. Therefore, it is important to create a model for calculating emissions of climate-active gases in young cattle rearing under variable indoor air environment conditions. This theoretical research resulted in a structural scheme for estimating emission levels from young animal housing that is centered on a predictive mathematical model. The model incorporated previously developed relationships for calculating CO2, CH4, NH3 and H2S emissions and integrated real-time data and operational parameters. A custom-designed mobile platform for multi-level concentration monitoring of climate-active gases recorded the indoor and outdoor air parameters of a young cattle rearing facility. The facility housed 518 young animals aged from 3.2 to 9.4 months. The data obtained were used to model and calculate the quantity of climate-active gas emissions depending on the age of the animals. Overall, the emissions in the studied facility were 781.0 kg/day for CO2; 24.9 kg/day for CH4; 1.1 kg/day for NH3; and 0.003 kg/day for H 2S. These findings will be included in recommendations for engineering and technological solutions to mitigate gas emissions from young cattle housing systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молодняк КРС</kwd><kwd>микроклимат</kwd><kwd>техническое средство</kwd><kwd>мобильная платформа</kwd><kwd>мониторинг</kwd><kwd>климатически активный газ</kwd><kwd>индикаторный газ</kwd><kwd>моделирование</kwd><kwd>модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>young cattle</kwd><kwd>indoor air quality</kwd><kwd>monitoring equipment</kwd><kwd>mobile platform</kwd><kwd>monitoring</kwd><kwd>climate-active gases</kwd><kwd>tracer gas</kwd><kwd>modeling</kwd><kwd>model</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 25-26-00112 «Мо­ дели оценки и прогноза влияния технологий выращивания молодняка крупного рогатого скота на интенсивность эмиссии климатически активных газов в окружаю­ щую среду».</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">Вторый, С.
