Получаемые при очистке семян подсолнечника на воздушно-ситовых сепараторах отходы имеют в своем составе крупные, мелкие и легкие примеси. Крупные органические примеси (остатки стеблей, листьев, корзинок, лузги и т.д.) относятся к сорной примеси и считаются непригодными к использованию в кормлении сельскохозяйственных животных. Однако они содержат много полезных питательных веществ: 224 г сырого жира, 132,01 г крахмала, 121 г сырого протеина, 6,03 г сахаров, а также высокий уровень обменной энергии и большой перечень макро- и микроэлементов, витаминов. С целью улучшения кормовых качеств и повышения биодоступности впервые была применена ферментация данных отходов. Установлено, что в продукте через 24 ч ферментации массовая доля жира в пересчете на сухое вещество в сравнении с исходным уровнем выросла на 78%, сырого протеина — на 10,3%, растворимых углеводов — на 29,4%, содержание крахмала повысилось на 29,4%, обменная энергия увеличилась на 21%. Все показатели биологической и химической безопасности после ферментации не превышали предельно допустимых значений. The wastes of the sunflower seeds cleaned in the air-flow screen separators contain heavy-, middle-, and light-weight particles. The fraction of heavy-weight organic particles (residues of the stems, floret discs, leaves, husks) is usually considered unusable in animal nutrition. However, this fraction contains relatively large amounts of nutrients: 224 gof crude fat in 1 kg, 132.01 gof starch, 121 gof crude protein, 6.03 gof sugars, high level of metabolizable energy (ME), a wide range of macro- and microelements and vitamins. In the presented pioneer study the effectiveness of the fermentation of this fraction aimed at the improvement of its feed value and availability of the nutrients was examined. It was found that after 24-hr fermentation the percentage of crude fat in the dry matter of the resulting product increased by 78% as compared to the initial raw product, crude protein by 10.3%, water-soluble carbohydrates by 29.4%, starch by 29.4%, ME by 21.0%. All studied parameters of biological and chemical safety of the fermented product fell within the respective permitted ranges.

Abstract. The agricultural sector faces challenges exacerbated by global trends such as climate change, market fluctuations and increased international competition. These factors require adaptation and implementation of new technologies to minimize the negative impact on yields and production stability. The importance of sustainable development of the agricultural sector is due to its role in ensuring food security and environmental stability. This requires management flexibility, innovation and collaboration with local communities and government to ensure sustainable development and socio-economic well-being. The purpose of this article is to analyze modern approaches to managing the sustainable development of agricultural enterprises, as well as assessing their effectiveness in the context of globalization. Methods. The article uses methods of analysis of scientific literature, comparative analysis, as well as case studies from various countries. This made it possible to generalize the experience of applying various strategies and practices for managing sustainable development. Scientific novelty lies in the development and application of a multidisciplinary methodological framework that integrates economic, environmental and social aspects to assess the effectiveness of existing management models in the agricultural sector in the context of globalization. An integrated approach includes analysis of indicators such as enterprise profitability, level of environmental impact and degree of social responsibility. Results. The main results are to identify the most effective modern approaches to managing sustainable development, which take into account the specifics of the agricultural sector and global economic trends. The article concludes that the integration of innovative technologies, increasing environmental responsibility and strengthening international cooperation are key factors for successfully managing the sustainable development of agricultural enterprises in modern conditions.

Relevance. The study of the physiological effect of the pancreas, which is a slaughter waste, on the body of calves of early weaning during the formation of digestive activity of the gastrointestinal type to improve the adaptive capabilities of the body of calves is of scientific and practical interest.Methods. Scientific and production experience was carried out on calves of the weaning period for 90 days. The pancreas of pigs (pancreas) was fed, obtained from the waste of the slaughterhouse production, dried with the use of lyophilization. Calves – analogs by breed, age, live weight – were formed into two groups (n = 8), the animals of the experimental group were given a feed product at the rate of 40 mg/kg of live weight daily with compound feed with group loose content. Live weight accounting (n = 8) and analysis of biochemical and hematological composition of blood (n = 5) were carried out.Results. Higher live weight gains of calves treated with PHC were established with improvement of biochemical and hematological blood parameters (without negative aftereffect). With a tendency to increase the level of total protein due to the albumin fraction, a lower level of urea is also positive evidence of an improvement in nitrogen metabolism. Higher creatinine levels in combination with glucose and alkaline phosphatase levels characterize an increase in the availability of energy exchange processes in the body of calves under the influence of a feed product. Positive differences in the levels of phospholipids, triglycerides, cholesterol against the background of lower bilirubin levels indicate an improvement in lipid metabolism, but also (indirectly) lipotropic liver function. Positive trends have been established in hematological indicators of blood, higher levels of erythrocytes, hemoglobin, hematocrit, lower levels of leukocytes.
