Исследования показали, что между целлюлозой и лигнином, как комплекса входящего в состав кислотно-детергентной клетчатки, корреляционная связь была высокой и отрицательной – r = -0,71. Установлено, что среднее содержание лигнина в отобранных образцах составляла 6,97%±0,06, корреляционная связь между структурными углеводами КДК и содержанием лигнина была незначительной и слабой – r = 0,15. Исходя из полученных корреляционных связей, можно сделать вывод, что при увеличении концентрации лигнина с возрастом растения происходит количественное уменьшение содержания целлюлозы в клеточной стенке растений.</p></abstract><trans-abstract xml:lang="en"><p>In the presented work, the composition of structural carbohydrates of corn silage was studied and their correlations with energy value were established. The research showed that between cellulose and lignin, as a complex included in the acid detergent fiber, the correlation relationship was high and negative – r = -0.71. It was found that the average lignin content in the selected samples was 6.97%±0.06, the correlation between the structural carbohydrates of ADF and lignin content was insignificant and weak – r = 0,15. Based on the obtained correlations, it may be concluded that with increasing lignin concentration with plant age, there is a quantitative decrease in cellulose content in the plant cell wall.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>структурные углеводы</kwd><kwd>целлюлоза</kwd><kwd>гемицеллюлоза</kwd><kwd>лигнин кукурузный силос</kwd></kwd-group><kwd-group xml:lang="en"><kwd>structural carbohydrates</kwd><kwd>cellulose</kwd><kwd>hemicellulose</kwd><kwd>lignin</kwd><kwd>corn silage</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">Wilson, J.
