Content

Building on the lecture on Feed Science (Bachelor), the following topics are explored in greater depth and expanded to include the effects (structure, degradability, digestibility, bioavailability) of a wide variety of technological treatment processes.
In addition, the technology and processing of finished compound feed is discussed in detail

1) Feed and its processing
- Root crops and by-products
- Cereals and by-products
- Oilseeds and their processed products
- Grain legumes
- Animal feed
- Mineral feed and additives

2) Concentrate feed mill
- Definition of some physical parameters: flow behaviour, bulk density, abrasion, pellet quality, mixing accuracy
- Deactivation of anti-nutritional factors, hygienisation
- Necessity and advantages/disadvantages of grinding, conditioning, pelleting, expanders/extruders, granulation, fat coating, flocculation on animal performance
- Influence of feed technology processes on starch digestion, on the change in the proportion of bypass protein (ruminants), on the digestibility of crude fat, crude fibre and crude protein, and increase in the content of metabolisable energy (ME)
- Basics of setting up a mixed feed plant

3) Feed preservation and feed quality:
- Special aspects of feed production in different land use systems
- Genotype x environment interactions
- Methods of feed preservation and effects on feed value
- Analysis and evaluation of current methods of feed quality research
Previous knowledge expected

Basic knowledge of animal nutrition and feed science
Objective (expected results of study and acquired competences)

Students will learn about the technological options available for treating feed and compound feed in order to make the production of animal-based foodstuffs more sustainable and thus more resource-efficient.

Students will:
- recognise important steps in the processing of individual components and compound feed for farm animals
- identify and evaluate important methods and results of feed quality analysis and products of compound feed production
- assess genotype x environment interactions and feed preservation measures on the feed value of different feed production systems
