Objectives

The aim of the course is to provide in-depth knowledge of factors that affect milk production and interactions
between reproduction, nutrition, behavior and lactation, including effects of lactation on the lactating animal.

After completing the course, the student should be able to:
- describe the development, anatomy and physiology of the mammary gland and surrounding tissue, including the physiology of lactation,
- explain how the quality and process characteristics of the milk can be affected by management, feeding and milking routines and the impact of the genotype on the composition and quality of the milk,
- give examples of interactions between reproduction and lactation,
- explain the milk ejection reflex, describe its significance for the possibility of emptying the mammary gland and describe in detail different steps in lactation and in milking routines, describe in detail how a milking machine works and describe the interaction between animals, humans and technology regarding milking,
- give examples of the most common pathogens and pathological changes affecting lactating udders and describe metabolic disease states that are linked to lactation,
- describe and propose different forms of methodology analysis used for quality determination of milk,
- on the basis of biological knowledge, assess and evaluate milking techniques, routines and care adjacent to milking to achieve optimal production, milk raw material and animal health and discuss the impact on the sustainability of milk production from a social, economic and ecological perspective,
- discuss and summarize scientific studies in lactation biology.

Content

The course content is udder anatomy, udder physiology, milk formation, milk extraction, udder health, care routines, milking technology, milking equipment and genetics. In addition, the composition of the milk is treated as an effect of feeding, milking and management routines as well as breeding, milk chemistry and milk analyses.

The course makes comparisons between different milk-producing animal species, such as cattle, water buffalo, goats, sheep and camels. The course is further based on basic knowledge mainly in cell biology, physiology and nutrition, but ethology, animal welfare, food science, production systems, sustainability and interaction between humans, animals and technology are also included.

The course compares different mammalian species, including humans, regarding lactation, but cows, sheep and goats are given the most space. During the first part of the course, the different topics will be covered in lectures, exercises and demonstrations. At the end of the course, the student works on a project/thesis.

Within the course the following general skills is trained: critical thinking, scientific communication and oral presentation

Formats and requirements for examination

Passed written and oral examination. Passed participation in compulsory course modules.
  • If the student fails a test, the examiner may give the student a supplementary assignment, provided this is possible and there is reason to do so.
  • If the student has been granted special educational support because of a disability, the examiner has the right to offer the student an adapted test, or provide an alternative assessment.
  • If changes are made to this course syllabus, or if the course is closed, SLU shall decide on transitional rules for examination of students admitted under this syllabus but who have not yet passed the course.
  • For the examination of a degree project (independent project), the examiner may also allow the student to add supplemental information after the deadline. For more information on this, please refer to the regulations for education at Bachelor's and Master's level.

Other information

  • The right to take part in teaching and/or supervision only applies to the course date to which the student has been admitted and registered on.
  • If there are special reasons, the student may take part in course components that require compulsory attendance at a later date. For more information on this, please refer to the regulations for education at Bachelor's and Master's level.

Additional information

It is recommended that the student has basic knowledge in cell biology and physiology.
