Course abstract

In this studies course enclose characteristics of nutrients and its importance in metabolic processes and animal produced production. Will be taught protein and it fractions, carbohydrates and it forms, lipids and fatty acids, mineral substances, vitamins it requirements and possibility of supply for different species and physiological groups of animals.

Learning outcomes and their assessment

The Master students acquire profound knowledge on the nutrients and their significance for the metabolism on the animal organism and production of produce. The Master students acquire the need for (norms) and supply of protein and its forms, carbohydrates and their types and groups, crude fats and fatty acid groups, mineral substances, including macro- and microelements, vitamins for animals of different species, age groups and productivity. Successful passed practical works. The Master students acquire skills regarding the main principles of nutrient rationing for animals of different species and groups, and how to choose the most appropriate types of feed, additives and preparation to meet the requirements in relation to feeding norms. Successful defense of a public report. As a result, the Master students are competent to apply the acquired skills, abilities and argue own opinion within the process of professional development, as well as to analyze more profoundly the scientific literature and to perform independent scientific research on feeding of animals. Successful passed final exam.
