    <p>Аннотация. Цель – выявление и объяснение паттернов биохимических показателей у коров с учетом особенностей породы. Методы. В настоящих исследованиях проводили сравнение выборок животных пяти пород (голштинская, тагильская, суксунская, сычевская, истобенская) по 17 биохимическим показателям. Общее число исследованных животных составило 407. Для анализа полученных результатов использовали методы статистического анализа, включающие метод нелинейного анализа главных компонент по алгоритму CATPCA (Categorical PCA). Научная новизна. Выбранный метод позволил обобщить большое число биохимических показателей и выявить процессы, по которым изученные группы коров различались в большей или меньшей степени. Результаты. Выделены и интерпретированы 5 главных компонент, объясняющих в сумме 67,4 % общей дисперсии. Некоторые наблюдаемые паттерны могут свидетельствовать о развитии патологических состояний животных. Схожие биохимические паттерны наблюдали с одной стороны у коров тагильской, голштинской и суксунской, а с другой – истобенской и сычевской пород. Наиболее близкими к физиологической норме были животные суксунской породы. У коров голштинской породы регистрировали более выраженные изменения, связанные с отрицательным энергетическим балансом.</p>

    <p>Abstract. The purpose of this study was to identify and explain patterns of biochemical parameters in dairy cows, taking into account the characteristics of their breed. Methods. A comparison was made of samples of animals of five breeds (Holstein, Tagil, Suksun, Sychevsk, Istoben) according to 17 biochemical parameters. The total number of animals studied was 407. To analyze the obtained results, statistical analysis methods were used, including the method of nonlinear principal component analysis using the CATPCA (Categorical PCA) algorithm. Scientific novelty. The chosen method made it possible to summarize a large number of biochemical indicators and identify processes in which the studied groups of cows differed to a greater or lesser extent. Results. Five principal components were identified and interpreted, explaining a total of 67.4 % of the total variance. Some observed patterns may indicate the development of pathological conditions in animals. Similar biochemical patterns were observed, on the one hand, in cows of the Tagil, Holstein and Suksun breeds, and on the other, in the Istoben and Sychev breeds. The animals of the Suksun breed were closest to the physiological norm. More pronounced changes associated with a negative energy balance were observed in Holstein cows.</p>
