Short description: During the course the properties of biological active substances and feed additives as well as their categorization and content in various feedstuffs, mechanism of biological activity, manner of administration. Moreover the profits come out of their usage and hazards for human and animals stemmed from their improper application will be discussed. The current specification list and demands needed to be fulfilled to register feed additives will be presented. Furthermore the necessity of inclusion of biological active substances to animal nutrition taking into consideration sources and quality of raw materials, applied methods of feeds preservation and processing, animal health and physiological state, environmental conditions as well as consumers’ requirements related to animal origin product used in human nutrition (meat, milk, eggs) will be taught.
Full description: Actual status of biologically active substances, their classification, content in raw feed components, mechanisms of biological action, use guide as well as the profits followed from use of them and potential danger for human and animals followed from the improper use will be presented. Also the demands related to the registration and current list of allowed additives. There the necessity of their application according to the kind and quality of feeds, used technology of feeds preparation, health status, environmental conditions and consumers demand (animals origin products quality) also will be presented.

Learning outcomes: After course completion In area of knowledge: 1. student knows classification of allowed to application in animal nutrition feed additives; 2. student is able to characterize the basic physical and chemical properties of biological active substances that are present in raw feed materials, feedstuffs as well as are applied as feeds additives; 3. student has a wide knowledge about mechanisms of biological action applied in animal nutrition substances and feed additives as well as potential danger for live organisms and environment followed from the improper use In area of skills: 1. student is capable to choose the kind and the chemical form of feed additive for different groups of animals; 2. student is capable to calculate the amount and share of applied feed additives in rations or concentrate mixtures with respect to chemical form and activity of chosen supplements; 3. student is capable to track down and practically use available information concerning chemical-physical properties different feed additives; student is able to analyse the data concerning feed rations composition and introduce, in reasonable causes, indispensable corrections. In area of social competences: 1. student is aware of responsibility for tasks that are realized in team; 2. student is open for looking for new information about specific subject and is conscious continuous of changes resulting from technological progress; 3. student obeys the rules of different feed additives application resulted from the law; student perceives relationship between the choice of biological additive and consequence of its application on live organisms and environment.
Assessment methods and assessment criteria: Subject completion – two positive evaluated written tests, ongoing assessment of learning achievements and activity (on the base of carried out tasks and students reports). To achieve subject positive grade student is obligated to present all reports and to achieve positive grade for all written tests.
