In the book in the form of questions and answers considerable attention is paid to data on the needs of all types of poultry in nutritional, mineral and biologically active substances, taking into account age of poultry. The characteristic of the main feed products is given, and the rational norms for including them in mixed feed for poultry are indicated. The role of vitamins, macro- and microelements, enzyme preparations, probiotics, prebiotics, antibiotics, organic acids, antioxidants, emulsifiers and other sources of biologically active substances in poultry nutrition is shown. Both nutritional factors that reduce the immune system and the causes of major feed diseases, which are related to the quality of feed, with violations in the rationing of nutrients and minerals, are indicated, and also biologically active substances, technologies for feeding and keeping poultry, methods of their prevention are given.
