Course responsible: Knut Egil Bøe
ECTS credits: 5
Faculty: Faculty of Biosciences
Teaching language: NO
(NO=norsk, EN=Engelsk)
Limits of class size:
Minimum 6 students
Teaching exam periods:
Spring parallel
Course frequency: Annually
First time: 2020H
Course contents:
In the first part of the course there are lectures and calculation exercises on the topics of animal thermoregulation, climate requirements and calculations on ventilation needs. Different ventilation systems and relevant measuring equipment are dealt with. There will be excursions to herds with different ventilation systems. Finally, climate measurements are to be made in commercial herds.
Learning outcome:


The student should have knowledge about thermoregulation in farm aninmals and their climatic demands. They should also have knowledge about the heat production and moisture production and the need for additional heating and different types of ventilation systems used for farm animals. 


The studenten should be able to calculate heat- and moisture production, maximum and minimum ventilation volumes and heat balance and the need for additional heating in rooms for animals.

General competence 

The student should understand thermoregulation in farm animals and their thermoregulatory behaviour

The student should understand  how the air exchange rate and the air quality influence both production and welfare in farm animals

Learning activities:
The course is a combination of lectures on the most important topics, practice exercises including calculation exercises, group work on climate measurements in farm animal rooms, colloquia where the teacher is present and excursions.
Teaching support:
The person responsible for the course will, during the entire teaching period, be available at fixed times within the office hours.
Notes from the lectures can be found on Canvas
