Goals
C1
The scope of the course includes classification and properties of selected biologically active substances present in feed and feed materials, as well as their impact on animal health and the quality of animal products. The course content includes, among others, vitamins and substances with antioxidant activity, pro-, pre- and
synbiotic additives, as well as polyunsaturated fatty acids as an important ingredient determining the quality and healthiness of animal products (meat, milk, eggs). The lecture content will be extended with a overview of research results on selected biologically active substances on the example of poultry and horses. As part of the practical section, students will be familiarized with the modern research equipment for measuring of antioxidant capacity in selected products / feed materials, and will perform selected procedures evaluating the antioxidant capacity of silage and assessing the oxidative stability of fats used in complete feed mixtures.
