Мировая практика показывает, что оптические методы могут служить эффективной альтернативой для разработки и изготовления приборной базы нового поколения, позволяющей определять качественные свойства материалов, в том числе сельскохозяйственных кормов (питательную ценность). Наиболее трудоемкая процедура разработки оптических приборов — это получение оптических калибровок (см. определение), которые обеспечивают интерпретацию значений косвенного параметра, характеризующего питательную ценность сельскохозяйственных кормов.</p><p>Исследование описывает процесс получения оптических калибровок методом варьирования контрольного показателя (на примере влажности корма) с последующим построением корреляционной связи между значением косвенного параметра (интенсивности фотолюминесценции) и контрольного показателя. Формирует методику построения алгоритмической связи для определения питательной ценности сельскохозяйственного корма. В том числе в портативном экспресс-анализаторе, функционирующем на основе фотолюминесценции.</p><p>Предлагаемая методика варьирования контрольного показателя может быть применена для получения оптических калибровок для экспресс-определения общего содержания жира и других показателей питательной ценности.</p></abstract><trans-abstract xml:lang="en"><p>Each type of agricultural feed has unique optical properties and nutritional value characteristics that must be taken into account at the stage of drawing up an animal feeding diet to ensure the rational management of economic processes at industrial livestock enterprises.</p><p>Arbitrage chemical methods for assessing the moisture content and nutritional value of agricultural feed are laborious in the implementation. World practice shows that optical methods can serve as an effective alternative for the development and manufacture of a new generation instrument base that allows determining the qualitative properties of materials, including agricultural feed (nutritional value).</p><p>The most time-consuming procedure for developing optical devices is to obtain optical calibrations (see definition), which provide interpretation of the values of an indirect parameter that characterizes the nutritional value of agricultural feed.</p><p>The study describes the process of obtaining optical calibrations by varying the control indicator (using the example of feed moisture), followed by building a correlation between the value of an indirect parameter (photoluminescence intensity) and the control indicator. Including in a portable express analyzer operating on the basis of photoluminescence.</p><p>The proposed method of forming a control indicator can be used to obtain optical calibrations for rapid determination of total fat content and other indicators of nutritional value.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотолюминесцентный контроль</kwd><kwd>экспресс-определение влажности</kwd><kwd>детектирование питательной ценности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photoluminescent control</kwd><kwd>rapid determination of humidity</kwd><kwd>detection of nutritional value</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">Кирсанов В.В., Беляков М.В., Никитин Е.А., Благов Д.А., Михайличенко С.М.
