Forskarutbildning

Generell information

Kursen ger 4 hp/ECTS. Nästa kurstillfälle är våren 2020.

Course Objectives

After completing the course the student shall be able to:

1) describe the basic theory behind the hyperspectral imaging techniques and have basic knowledge of contemporary spectral instrumentation (cameras).
2) conduct basic hyperspectral analysis and relate the spectral data obtained to reference information.
3) show a basic knowledge on how to operate software used to analyse data from hyperspectral technology and chemometric information.

Content (current course)

The course offers an introduction to hyperspectral imaging using desk top/lab, airborn (drone) and satellite techniques for the classification and quantification of spatial distributions and chemometrics in animal, agricultural, food, ecology and related sciences. The students will learn to interpret hyperspectral images using chemometrics and multivariate image and data analysis by user-friendly and intuitive software solutions.

The students will be introduced to the basics of chemometrics, near infrared spectroscopy and digital imaging by state of the arte lecturing, practical laboratory work using, high-speed hyperspectral, video meter and satellite imagines e.g. the Sentinel-2 Satellite for monitoring land and vegetation.

Applications will be presented on animal tissue, plants, food products (e.g. cheese and meat), field plots and landscape levels.

Objective, including learning outcomes

After completing the course the student shall be able to: - describe cell wall factors limiting digestibility and intake in ruminants. - describe different techniques for evaluting forages. - explain the effects of antinutritional factors in plants on animal performance. - describe the use of stable isotopes in forage science. - explain the importance of forages in ruminant nutrition for the production of greenhouse gases (methane). - use practical methods for in vivo and in vitro measurements of methane production from enteric fermentation in cattle.

Content (senaste kurstillfället)

This is the fifth edition of the popular course. We will continue to focus on general aspects of forage evaluation, but this time we also include special sessions about anti-nutritional factors and the use of stable isotopes in ruminant nutrition. The lectures and exercises will be given by several leading scientists e.g. Professor Pekka Huhtanen (SLU), Professor Makkar Harinder (FAO), Dr Peter Udén (SLU), Professor Marin Riis Weisbjerg (Århus University) and Dr Seija Jaakola (Helsinki University).

The schedule includes general topics for all types of studies concerning forage science and ruminant nutrition, such as experimental techniques, modelling and important literature reviews. Teaching in class will be combined with practical exercises in analytical techniques to give a deeper understanding of the subject. Scientific articles will be presented and discussed to highlight important scientific progress. Examination includes solving practical problems as written "take home" project. The event also includes a social program with great possibilities to make contacts with fellows from different scientific environments

Objective, including learning outcomes

After completing the course the student shall be able to - describe in detail feed factors influencing nutritive value of feeds, especially those related to forage chemistry. - describe digestion of nutrients in different segments of the digestive tract of ruminants. - give details of mechanisms influencing feed intake. In addition to lectures the course includes paper discussions to support lectures and explain mechanisms in more detail. Calculation and modeling exercises will be carried out to understand quantitative aspects of nutrient digestion.
