С целью разработки алгоритма оценки физиологической упитанности молочных коров по параметрам маклаков, крестца и голодной ямки на ферме ГУП «Григорьевское» проведено исследование 80 гол., которые были распределены на группы упитанности (от 1 до 5). Исследования проводились в ноябре 2021 г. во время утреннего доения. Сбор массива данных производился с использованием 3D ToF-камеры O3D 303. Предварительно было проведено моделирование установки трехмерной камеры на ферме, разработан алгоритм, учитывающий рост коровы и расстояние от высшей точки позвоночника до трехмерной камеры. Разработан алгоритм оценки физиологической упитанности молочных коров в соответствии с оценкой состояния маклаков, крестца, голодной ямки, определяющий наивысшую точку холки, пропорции между длиной и шириной туловища, а также глубиной голодных ямок и выраженность хвостовой связки. Разработано программное обеспечение, позволяющее регистрировать номер коровы и определять балл упитанности, а также показывать динамику изменения упитанности животного. Обработка данных проводилась в соответствии с разработанным алгоритмом. Обработка изображений проводилась методом регрессии. Сравнение оценки упитанности коров, проведенной согласно разработанному алгоритму, и оценки экспертов показало, что погрешность работы алгоритма в диапазоне упитанности 2…4 балла составила в среднем 10%. При определении упитанности коров, имеющих пограничное и граничное состояние упитанности (1 и 5 баллов), ошибка измерения предложенным алгоритмом увеличивается до 25%. На основе полученных результатов для дальнейших исследований рекомендовано обучить нейронную сеть; определить корректирующий коэффициент для 1 и 5 баллов упитанности; доработать программное обеспечение, разработать пользовательское ПО с разработкой проходного станка бонитировки и провести испытания.</p></abstract><trans-abstract xml:lang="en"><p>Cow’s body condition scoring (BCS) based on neural network algorithms is necessary to monitor the health and productivity of the animals. To develop an algorithm for assessing the physiological fatness of dairy cows according to the parameters of the fermur heads, the sacrum and the hunger hollow, the authors studied eighty animals on a farm of the state unitary enterprise “Grigorievskoe”, which were divided into fatness groups (from 1 to 5). The studies were carried out in November 2021 during the morning milking. Data were collected using a 3D ToF camera O3D303. Previously, the installation of a three-dimensional camera on the farm was simulated, and an algorithm was developed that takes into account the cow height and the distance from the highest point of the spine to the three-dimensional camera. An algorithm for assessing the physiological fatness of dairy cows (BCS) has been developed to take into account the condition of the fermur heads, the sacrum, the hunger hollow, which determines the highest point of the withers, the proportions between the body length and width, as well as the depth of the hunger hollows and the severity of the caudal ligament. Software has been developed to register the unique number of a cow and determine the BCS, as well as show the dynamics of changes in the animal’s fatness. Data were processed in accordance with the developed algorithm. The image was processed using the regression method. Comparison results of the BCS of cows, obtained according to the developed algorithm, and the experts’ assessment showed that the algorithm error in the fatness range of 2…4 points averaged 10%. When determining the BCS of cows with borderline and limit fatness state (1 and 5 points), the measurement error by the proposed algorithm increased to 25%. Based on the results obtained, the authors recommend pre-setting a neural network for further research; determine the correction factor for fatness points 1 and 5; finalize the software, develop customized software and an automatic system for body condition scoring, and conduct tests.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лактирующие коровы</kwd><kwd>оценка состояния тела (BCS)</kwd><kwd>3D-датчик TOF</kwd><kwd>бесконтактная оценка упитанности</kwd><kwd>маклаки</kwd><kwd>крестец</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lactating cows</kwd><kwd>body condition scoring (BCS)</kwd><kwd>3D TOF sensor</kwd><kwd>non-contact body condition scoring</kwd><kwd>fermur heads</kwd><kwd>sacrum</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Совета по грантам Президента Российской Федерации на право получения гранта Президента Российской Федерации для государственной поддержки молодых российских ученых-кандидатов наук – МК-2513.2022.4.</funding-statement><funding-statement xml:lang="en">The work was supported by the Council for Grants of the President of the Russian Federation for the right to receive a grant from the President of the Russian Federation for state support of young Russian scientists – PhD holder – MK-2513.2022.4.</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">Pavkin D.Yu., Dorokhov A.S., Vladimirov F.E., Dovlatov I.M., Lyalin K.S.
