The aim of the study is to compare the content of nutrients, including selected macro- and micro-elements, in and offal (liver, heart, kidneys, tongue, brain) derived from animals (calves, beef cattle, and lambs) that are fed and maintained in organic production conditions. The experimental material consisted of 60 animals: 20 calves, 20 beef cattle, and 20 lambs. This research was carried out using Limousin cattle and Ile de France sheep. From the obtained results, it is concluded that the physicochemical and nutrient composition varied significantly among the organs and species studied. Almost all byproducts are a rich source of trace elements, whose levels/amounts are usually much higher in byproducts such as offal than in muscular tissues. Also, for economic reasons (profitability), byproducts (offal) can be commercially sold for human and animal nutrition. Byproducts are processed and incorporated into many food products and provide competitive nutritional value for use by tissues and muscles (vitamins and elements).
本研究的目的是比较在有机生产条件下饲养和维持的动物（犊牛、肉牛和羔羊）的肉类及内脏（肝脏、心脏、肾脏、舌头、大脑）中营养成分的含量，包括选定的常量和微量元素。实验材料包括60只动物：20头犊牛、20头肉牛和20只羔羊。本研究使用了利木赞牛和法兰西岛绵羊。从所得结果可以得出结论，在所研究的器官和物种中，物理化学和营养成分存在显著差异。几乎所有副产品都是微量元素的丰富来源，其含量在诸如内脏等副产品中通常比在肌肉组织中高得多。此外，出于经济原因（盈利能力），副产品（内脏）可用于商业销售，供人类和动物营养使用。副产品经过加工后被纳入许多食品中，并为组织和肌肉提供具有竞争力的营养价值（维生素和元素）。
