The study programme Master in Animal Science.
Introduction to theories that influence the supply and utilisation of nutrients for ruminants. Performance of in vivo experiments with cannulate dairy cows. The experiment will measure fermentation products in the rumen, digestion kinetics and nutrients in blood and animal products. Introduction to and use of systems and computer tools for optimising feed allowances for ruminants. The in vivo experiment and laboratory work will be carried out in the June block.
After the course has been completed, students should have an elementary and applied understanding of: 1. Methods used for chemical analysis of feed and analytical methods for determining metabolic compounds in blood and animal products. 2. Dietary metabolism in the digestive tract. 3. Mathematical description of nutrient metabolism in the digestive tract. 4. Absorption of nutrients from the digestive tract and how it is affected by diet composition. 5. Intermediary metabolism of absorbed nutrients and how they affect nutrient utilisation and production responses. 6. Regulation and determination of feed intake. 7. Determination of the nutritional value of feed for ruminants. 8. Introduction to new systems for feed evaluation in ruminants. 9. How feeding strategies in ruminants affect nutrient requirements and production responses. 10. Mathematical methods and tools for optimising feed allowances. After the course has been completed, the student shall have elementary knowledge of practical feed planning and ration optimisation for ruminants.
The course is a combination of lectures and exercises including performance of an animal experiment.
Materials to be copied will be handed out. These cover the subjects brought up in the lectures. It is assumed that the students will find literature on their own, which will be needed to carry out the exercises.
KJM110, KJB200, HFE200, HFE202, HFE203, HFX201, HFX202, HFX210, HFX250, HFX251.
The animal experiments and laboratory work are compulsory.
Student assessment will be as oral examination and exercises in a ratio of 60:40.
