General animal nutrition (176009)
Students will learn to evaluate the nutrient contents in feeds and nutritional needs of animals - a basis for the correct preparation of diets on the farm, planning crop and livestock production and additional activities facilitating enrollment to doctoral studies. Students will learn about nutrients present in feeds as well as about the nutrient needs of different types and categories of animals. The analytical methods for nutrient quantification will be learned (dry matter, crude protein, crude fat, crude fibres, water soluble sugars, starch, neutral detergent fibres, acid detergent fibres, lignin, digestible fibres etc.) and discussed. The effect of nutrition on the course of livestock production in several distinguished production types will be learned and discussed (for example: lactating dairy cows, grazing animals, poultry etc.).
Type of course
- Graduate studies / MS Courses taught in English (Elective course, 1 semester, 1 year)
Teaching hours: 60
Sufficient (2): 60-70
Good (3): 71-80

Conditions for obtaining signature
• Participation in teaching.
• Preparation and presentation of a seminar paper.
After completion of the Module, students will be competent to use their knowledge in practical conditions. They will know how to evaluate quality of feeds in compare to nutritional, health and productive needs of different types of animals (i.e. poultry, pigs, beef etc). They will learn how to evaluate and compare different types of feeds. Main objective of this module is to prepare students to on farm conditions and how to use basic knowledge in animal feeds quality in order to optimize on farm production.
Types of instruction
Trace elements and their physiological role in animal nutrition
Comparison and implementation of various systems assessment of the nutritional value of feed. Visit to the various farms: poultry, pig and lactating dairy farm - field exercise
|Learning outcome||Evaluation methods|
|Recognize the importance of nutrients essential in animal feeding. Distinguish differences between the biological role of different nutrients.||Written or oral|
|Describe the process of feed digestion and metabolism of nutrients. Compare the needs of nutrients and energy in different animal species.||Written or oral|
|Explain the impact of nutrition on animal welfare, human health and the environment||Written or oral|
|Define the specific chemical analysis of diverse nutrients in feed and fodder, and on the basis of the results obtained with this analysis design the animal diets.||Written or oral|
